    0. Introduction

    The institutional investor is in the business of understanding, pricing and managing risks to earn a

    return for the benefit of all stakeholders. In this paper I discuss how structured products can be used by

    institutional investors.

    In a perfect world (Arrow-Debreu state-claim framework) there exist enough securities to recreate any

    payoff. Some assumptions of this idealized world are: there exist basic securities, Arrow securities,

    that they have a risk-free payoff in any state, no transaction cost, no information asymmetry, all

    investors have the same expectations. Then derivatives are redundant instruments, as they can be

    replicated. The price of the replicating strategy should be equal to the price of the derivative; otherwise

    there is an arbitrage opportunity.

    Several research papers discuss the optimal existence of derivatives. [Merton 1971], [Carr Madan

    2001], [Carr Madan 1998], [Liu Pan 2003], [Ross 1976]) The research results are usually dependant

    on assumptions about the process of the underlying. The case of including derivatives in an investorsportfolio is usually solved making the assumption that investor preferences follow a certain

    mathematical function. The optimal investment in derivatives is then determined as the solution which

    maximizes the investors utility function. A closed form solution may or may not be available

    depending on the assumptions about the underlying process and the utility function.

    I treat the problem in a practical, applied way. Needless to say, financial markets have readily justified

    the existence of derivatives and derivatives related products. The focus is on how structured products

    can be handy to an institutional investor, as opposed to how do we price, replicate and hedge them.

    While in the back of every properly priced derivative there is a lot of mathematics, in this paper I

    focus on the investment interpretation and application.

    I present structured products as a natural investment choice of an institutional investor who faces the

    business constraints of a liability stream and of stakeholder and client expectations. Their main

    applications are in creating risk-return flexibility, isolating risks and providing exposure opportunities.

    I point at possible specific applications, but there is no almighty product that will magically solve all

    investment problems and unless a specific investor is consider it is impossible to make a strong

    statement about the best choice.

    For a retail institutional investor, structured products present new ways to reach the investment needs

    of clients by adding new products to the product basket, preserving the level of distribution fees and

    increasing the ability to raise new money.

    For the pension or trust fund investor, in particular in a core-satellite framework, structured products

    provide payoff flexibility, bundled or unbundled exposure to new and old asset classes, and can be

    optimally added as satellites to the investment portfolio.

    For the asset manager in an insurance company, structured products stand out with their ability to

    implement sophisticated investment views, and to isolate and hedge risks.

    Research on the pricing and replication of some of these structures are widely available; others do not

    have a closed-form solution. The most flexible approach is using Monte Carlo (MC) pricing tool

    Based on the martingale approach of derivatives pricing, this approach can price any possibly payoff

    and has gained widespread acceptance among practitioners.

    1. What are structured products?

    1.1 A definition

    Structured products are investment instruments that combine at least one derivative with traditional

    assets such as equity and fixed-income securities. The value of the derivative may depend on one or

    several underlying assets. Furthermore, unlike a portfolio with the same constituents the structured

    product is usually wrapped in a legally compliant, ready-to-invest format and in this sense it is a

    packaged portfolio.

    The usual components of a structured product are a zero-coupon bond component and an option

    component. The payout from the option can be in the form of a fixed or variable coupon, or can be

    paid out during the lifetime of the product or at maturity. The zero-coupon bond component serves as

    buffer for yield-enhancement strategies which profit from actively accepting risk. Therefore the

    investor cannot suffer a loss higher than the note, but may lose significant part of it. The zero-coupon

    bond component is a floor for the capital protected products. Other products, in particular variousdynamic investment strategies, adjust the proportion of the zero-coupon bond over time depending on

    a predetermined rule.

    From an economic point of view, the structured product can be broken down in two main components:

    Investment view + Payoff structure = Structured product

    The investment view is driven by factors such as:

    Investor expectations towards the underlying: bearish, flat, bullish, range bound, ladder etc Choice of underlying. The underlying may be available in a readily investable format or has to

    be synthetically extracted:

    o Single stocko Basket of stockso Index or multiple indiceso Mutual fund, hedge fund, Fund of Hedge Funds, discretionary managero Systematically rebalanced strategyo Volatility, correlation, dispersiono Hybrido Credito Inflationo Commodities etc

    The investment view may be based on fundamental or technical research. The choice of the underlying

    may depend on the market, on the investors expertise, and on fundamental factors.

    Payoff structure

    The payoff structure is a mathematical formula applied on the underlying. The features of the payoff

    structure will include:

  • 8/8/2019 Deriv Survey

    5/42

    Cash flows timing: periodic coupons from an underlying that pays none; total lump paymentwhen underlying pays coupon; variable coupon or fixed coupon; fixed coupons during certain

    periods of the life of the product etc.

    Risk profile: leverage, conditional capital protection, partial capital protection, full capitalprotection

    Maturity: Short-term, medium-term or long-term

    The importance of both components is evident when we look at the fundamental exposure types in the

    next section. The focus here is that despite the fact that the option types have been known for a long

    time, the investment view gives them a different interpretation.

    1.2 The fundamental exposure types

    The fundamental exposure types are the generic option payoffs. Combining these with a long zero

    coupon bond gives the primal structured products, some of which have not failed to go out of fashion.

    Figure 1 shows clearly the interaction between investment view and payoff structure. Some authors

    seem to refer to prefer bullish payoffs, and consider only the payoffs in upper row of the table,corresponding to the bullish investment view as structured products.

    The Delta one (certificate) provides full exposure to the underlying. Investor gains wealth as

    underlying appreciates and loses wealth as the underlying depreciates. The payoff is the same

    independent of the investment view. The other 4 payoffs are:

    1) Bullish investment view, yield-enhanced or return-enhanced exposure capped upside,unlimited downside. Investor prefers to sell the upside potential and receive a higher return.

    Investor is actually bullish on the underlying, but prefers to cash in the expected return, ratherthan wait for the uncertain appreciation to realize. Investor practically accepts the downside

    risk of the underlying and receives a premium for that, which results in a higher yield

    compared to the underlying.

    2) Bullish investment view, capital protected exposure floored downside, unlimited upside. Theinvestor pays a premium to ensure downside protection, but keep the upside exposure.

    3) Bearish investment view, yield-enhanced exposure capped upside, unlimited downside.However the structure pays of when the underlying decreases in value.

    4) Bearish investment view, capital protected exposure floored downside, unlimited upside.Again the structure pays as expected if the underlying decreases in value.

    Typically, only payoff type 2), the long call, payoff is considered a capital protected payoff. Yet for an

    outright bearish investor, this payoff is detrimental as it leaves him exposed to an appreciation of the

    underlying.

    The investment view is intrinsically connected to the split between yield-enhancement products, where

    the investor chooses the higher risk-return combination, and capital protection, where the investorprefers a lower risk-return combination.

    These generic payoffs have been embraced by the market. I show 3 widely known products that can be

    directly matched to 3 of the generic payoffs and also present an investment case for their use. These

    are:

    1) The Delta One (Certificate) (Figure 2 & Figure 3)2) The Reverse Convertible as an example of bullish yield-enhancement payoffs (Figure 5

    &Figure 4)

    3) The Capital Protected Note as an example of bullish capital protected payoffs (Figure 6)

    Other payoff structures cannot be easily classified as only yield-enhancement or capital protected type.

    I discuss some of them Section 2.1

    Reverse Convertibles

    Reverse Convertibles are yield-enhancement strategies with short maturity

    A coupon is always paid.

    Depending on the product features the investor is exposed to a different

    Capital Protected Notes (CPN)

    Capital protected notes are downside protected investments

    100% of invested capital plus a coupon (or upside participation).

    We go long a zero-coupon bond and long an option with upside

    exposure.

    Short-, mid- or long-term investment horizon.

    The zero-coupon bond plus option component of the structure has direct implication on the taxation of

    structured products. I review these in Appendix 2.

    2. Applications of structured products in the portfolio of an institutional investor

    In a general framework, the two applications of structured products are payoff flexibility and isolatingor bundling risks.

    1. Payoff diversity and flexibility, payoff timing flexibility, leverage

    It is almost impossible to define payoff diversity and flexibility that structured products can provide. I

    present six structures that exemplify the payoff flexibility and diversity that structure products can

    offer. These are:

    1) The Autocallable (Figure 7,Figure 8 &Figure 9)2) The Reverse Convertible Autocallable (Figure 10 & Figure 11)3) The Springboard (Figure 12)4) The CertiPlus (Figure 13)5) The Plain Turbo Certificate (Figure 14)6) The Leveraged Airbag (Figure 14)

  • 8/8/2019 Deriv Survey

    10/42

    The Autocallable and the Reverse Convertible Autocallable can be easily classified as yield-

    enhancement products. The Springboard is a capital protected product. However the Certiplus, the

    Plain Turbo Certificate and the Leveraged Airbag cannot be easily classified into one of the

    fundamental exposure types, because they are vehicles to express sophisticated investment views.

    All examples are applied to a single stock underlying. Considering how central correlation is in thepricing of baskets, I present examples in section 2.2.

    The autocallable acts as a rational investor who has a range bound view on the underlying. If the

    underlying appreciates enough, it is autocalled and the structure ceases to exist, that is, the payoff is as

    if the investor has taken profit on the underlying. On the other hand of the underlying stays underwater,

    the investor receives a coupon. The worst-case scenario occurs when the underlying goes down by

    more than the investor expected. Then the investor will receive the bad performing underlying, but this

    loss is nevertheless partially offset by the coupons that the investor receives until maturity.

    Autocallables

    Autocallables are yield-enhancement strategies

    The structure autocalls if the underlying is above the trigger level in the

    years before maturity. The investor receives a coupon equal to the number

    of years multiplied by the initial coupon level.

    If underlying matures above the initial level and has not been autocalled,

    investor receives a coupon equal to the number of years multiplied by the

    initial coupon level.

    If underlying matures between barrier and initial price, investor receives

    100% back.

    If the underlying matures below the barrier, investor receives only theperformance of the underlying. This is the worst-case scenario.

    We go long a zero-coupon bond, short a down-and-in put (DIP), long a

    series of binary calls

    2. Isolating risk and gaining exposure: volatility, correlation, inflation, credit, hedge funds

    Structured products provide the capacity to isolate and trade asset classes that are mixed-in in

    traditional assets or may not be directly investable due to constraints on the asset side or the investor

    side. I look at 5 specific investment classes: volatility, correlation, inflation, credit and hedge funds.

    Not all of them are recognized as asset classes; however the existence of structured products showsinvestor interest.

    An asset class is a set of investments that exhibit similar and distinctive investment characteristics

    (return, volatility and relationship to the returns of other investment assets). The asset class represents

    a distinctive type of risk. For accepting this risk any rational investor expects to earn an appropriate

    return. The rational investor judiciously accepts risk and expects an appropriate return.

    2.1 Volatility

    Derivatives are both directional and volatility instruments (Neftci provides an excellent exposition).That is, the investor makes a bet both on the direction which the underlying will take and on implied

    vs. actual volatility. If the actual volatility exceeds implied volatility the long side of the transaction

    will realize a profit, assuming all other factors the same. Vice versa, if the actual volatility is lower that

    implied volatility the short side of the transaction will realize a profit at the maturity of the option.

    Volatility is an exogenous input in the Black-Scholes (or another pricing formula or Monte carlo

    simulation) and it shows the volatility view of the investor.

    The specific dynamics of volatility can be summarized in the following 4 points

    It jumps when the market crashes It reverts back towards its long-term mean

    It experience high and low regimes It is usually negatively correlated with the underlying asset return

    [GM 1998], [Qu 2000] discuss volatility as an asset class. [Carr and Madan 1998] provide the

    replication and pricing formula for volatility and variance swaps.

    Volatility structured products can be used to make sophisticated bets on volatility. An excellent

    exposition on the pricing of volatility products are the classic [Derman ??], [Hosker ??] and [Mougeot

    2005]. The following table summarizes some of the applications.

    While volatility swaps on currencies exist, the main application seems to be in equity index and swap

    rate volatility. For an indexed investor, the volatility swap is of direct interest as it can help be used to

    manage the tracking error. Apart from the swaps presented above, other volatility products are:

    Volatility options An example is a call option on volatility. The option gains rapidly in valuewhen volatility increases sharply.

    Volatility swaps combined with equity futures volatility swaps entail an implicit directionalview on market price movements. There is evidence of negative correlation between the equity

    market performance and the level of volatility. Volatility tends to be high during market

    crashes. Thus, the seller of volatility swaps has an implicit expectation that the equity market

    will increase in values and the buyer has an implicit expectation that the equity market will

    decrease in value. To hedge the directional effect of the volatility swap the investor can trade

    equity futures.

    Volatility bonds the coupon is proportional to the difference in the swap rates of a certainmaturity, for example the 20 year swap rate, between the start and the end date of each year.

    The investor is buying a series of 20 year swaption straddles.

    Here I show an example where variance swaps can be directly used to hedge secondary guarantees

    offered by insurance companies. Secondary guarantees exist in two forms: death benefits and living

    benefits. Among living benefits the most popular product are the guaranteed minimum withdrawal

    benefits (GMWBs), which guarantee the principal, may allow step-ups and allows set percentages of

    withdrawal each year, even if account values is zero. The key attraction to customer of this product is

    the protection against another bear market and they give life insurers a competitive advantage over

    mutual fund providers.

    The main risk for the insurer offering such a guarantee is a prolonged equity downturn which poses a

    catastrophe type risk. The GMWBs will go deep in the money potentially creating large losses forthe insurance company if they are not properly hedged.

    Because secondary guarantees are long-term illiquid benefits with liabilities that are expected to

    extend over a 20-30 year time period and contain the uncertainty of policyholder utilisation rates, there

    are essentially no financial derivatives that can be found to form a perfect hedge. Even if derivatives

    were available for 20-30 year periods, the counterparty risk over such long durations would be

    unacceptably high.

    The long-term illiquid nature of the benefits means that they are suited to dynamic hedging strategies.

    The insurer will establish a portfolio of fairly short-dated futures and put and call options which can be

    rolled over providing a rolling hedge to offset the guarantee risks based on assumptions about futuremarket behaviour and policyholder utilisation. The dynamic element of the strategy lies in using

    futures and options that are typically fairly short dated at around 3-9 months as these are normally the

    most liquid. By rolling the positions over and adjusting those to reflect changes in the book, often on a

    daily basis, a fairly effective continuous hedge against most market risks can be achieved.

    The three Greeks of concern are:

    Hedging Greek Risk Typically used instruments

    Delta Change in the market value of the

    fund

    Equity Futures

    Vega Change in the market volatility Put and call options (straddles)

    Rho Change in interest rates US Treasury futures

  • 8/8/2019 Deriv Survey

    17/42

    The straddles are the easiest way to partially hedge volatility, however they do not provide pure

    exposure to volatility. The problem with the straddle is that once the stock price has moved away from

    the initial level, the straddle delta is not zero anymore. Also, since both options are initially in the

    money, straddles are usually expensive.

    For the insurance company, the variance swap is the best hedging solution. The variance swap is aforward contract that pays at maturity the difference between the realized variance of an underlying

    and the initially defined variance strike price K.

    Carr and Madan show that the variance swap can be replicated by a continuum of puts and

    calls inversely wghted by the sware of their strike price. The solution is model-free. The perfect hedge involve buying a continuum of put with strike from 0 to Fo, the current

    level, and buys a continuum of call options with strikes from Fo to infinity:

    2.2 Correlation

    Correlation is a key input into the pricing formula of baskets of securities. Therefore, in a manner

    similar to betting on volatility, the investor can bet on correlation. If realized correlation is lower or

    higher than the implied correlation the investor may realize a gain or loss depending on whether the

    investor is long or short correlation.

    While in linear payoffs correlation and volatility are positively correlated, there are payoffs where the

    investor can profit from high volatility and low correlation of the stocks in the basket. These are the

    so-called dispersion payoffs. I give an example to show why such a product can be interesting for an

    investor.

    17

  • 8/8/2019 Deriv Survey

    Correlation is usually measured as

    This formula clearly makes the assumption that the log returns of the two assets are normally

    distributed, and may underestimate or overestimate true correlation if this is not the case.

    Correlation is a measure of the diversification and is closely linked to the volatility of the basket.

    To show the link between correlation and volatility, let us consider a basket of two stocks, A and B,

    and assume that both have a constant volatility of 25%. As the correlation increases from -100% to

    100% the volatility of the basket will increase at a decreasing rate and will finally be equal to the

    arithmetic average of the volatilities of the two stocks (Figure 16). The non-linear rate of decrease isdue to the fact that volatility is a power function in correlation.

    Correlation is not considered a separate asset class, possibly due to its direct linked to volatility.

    Correlation in credit derivatives markets has become a key input commensurate to volatility in equity

    derivatives markets. I discuss it briefly in section 2.4. Correlation between asset classes is also still a

    research topic.

    Correlation is also the measure of diversification. Correlation is low when the stocks in the basket

    move apart, and is high when the stocks in the basket move concordantly. When the market is bullish

    and correlation is high, the investor wants to be long correlation, so that he can profit from the

    leverage effect. Yet, when market is bearish and correlation is high the investors wants to be short

    correlation, so that he can benefit from the diversification effect.

    Dispersion bets are bets that stocks in the basket will move in different directions. The best payoff isachieved when we take the difference between the best performing stock and the worst performing

    stock. This can be achieved through a combination of a long lookback call plus a long lookback put.

    18

  • 8/8/2019 Deriv Survey

    19/42

    This is obviously the primal volatility trade, and due to the lookback feature it can be prohibitively

    expensive.

    With the proper payoff structure, the dispersion of the stocks in the basket can generate higher IRR or

    consistent and uncorrelated performance.

    First, I compare the price and the IRR of a structured product that pays off the average of call spreadson a basket of stocks and a structured product that pays the call spread on the average of basket of

    stocks. I introduce the floor and the cap in order to obtain financially sensible prices and results.

    Basket of Call Spreads

    The coupon is the average of the call spreads on the underlyings

    100% of invested at maturity.

    The coupon depends on the return of the stocks in the basket and is

    capped.

    The annual coupon is paid accordingly to the following formula:

    We go long a zero-coupon bond and 3 long call spreads on the indecis.

    Mid- to long-term investment horizon.

    The call spread on the basket clearly dominates the average of the call spreads, because of the bubble

    period. The call spread on the basket is a dispersion trade compared to the basket of call spreads as the

    average of the basket out or underperforms the individual call spreads as the indices disperse up or

    down, while the call spread on the individual indices does not allow them to disperse outside of the

    cap and the floor. Despite the fact that there is no leverage applied, we observe a leverage effect thatwill clearly be stronger if correlation would increases and vice versa.

    2.3 Inflation

    Inflation presents a major risk to institutional investors concerned with capital preservation. The

    purpose of inflation derivatives and inflation structured products is the transfer of inflation risk.

    Although cash instruments already exist (inflation-linked bonds) inflation derivatives allow for tailor-

    made solutions. I discuss some of these after a brief review of the market.

    Inflation products are attractive to banks, pension funds, mutual funds and insurance companies.

    Institutions that are natural inflation payers can benefit from issuing inflation-linked debt in the market

    or from selling inflation. Inflation derivatives are attractive to debt investors who prefer real returns

    rather than nominal returns or to investors who are looking to hedge their inflation exposure.

    Furthermore, inflation linked securities will have a lower nominal cost to the issuer reflecting the

    lower risk premium as the real rate is guaranteed.

    23

    Investment managers face implicit inflation risks. Inflation receivers are typically institutional

    investors who need to pay inflation-linked cash flows. For example, the liabilities of pension and

    superannuation funds, workers compensation insurers and disability insurers are linked directly to

    inflation or indirectly linked to inflation through salary or other income levels. Furthermore, fixed-income specialist mutual funds/unit trusts have been established to invest in inflation indexed

    securities. If the current trend of a changeover from defined-benefit to defined contribution pension

    schemes continues, retail investors and mutual funds can become key players in the market of private

  • 8/8/2019 Deriv Survey

    24/42

    pension schemes, long-term savings solutions and retirement income products and they will look to

    provide inflation hedge for their clients.

    Figure 25The case of inflation as a separate asset class is discussed in [Borutta 1997] and [Lamm 1998]. The

    key arguments for considering inflation as an asset class considering its risk-return characteristics are:

    Inflation linked securities will underperform conventional investments in times of low inflation,but will outperform at times of high inflation. This is a distinguishing return feature.

    Inflation linked securities have lower volatility than conventional securities The correlation of inflation linked securities with other asset classes is similar to conventional

    fixed-income securities. At time of high inflation however, it will be negative as inflation

    linked securities will not experience loss of value.

    The whole variety of fixed-income payoffs such as forwards, various option on inflation, swaptions on

    inflation etc, can be applied to inflation. Unlike inflation-linked bonds, inflation derivatives can be

    applied as an overlay on the existing asset allocation, or included as partial hedges.

    The inflation swap is a flexible solution to hedge inflation risk. It is a bet on the breakeven inflation

    level and is similar to an unfunded interest rate swap, except for the fact that the underlying payments

    depend on the level of an inflation index.

    2.4 Credit

    Credit-sensitive bonds are one of the first yield-enhancement investments available. By investing in

    corporate bonds and loans, or sovereign debt the investor receives an additional return spread over the

    risk-free rate. The investor however is exposed to the default of the counterparty.

    The credit-sensitive bond is (similar to) a short put on the value of the company. While credit risk hashistorically been regarded as illiquid, credit derivatives have successfully isolated it from the

    underlying credit asset (bond, loan etc). The CDS is the basic credit derivative, and economically it is

    a short put. Packaged with a bond component, the CDS is similar to a reverse convertible. Unlike the

    reverse convertible however, the premium is paid over the life of the product. FtD baskets are the

    credit equivalent of the worst-of-put baskets from the universe of equity products.

    Historically, credit has been regarded as illiquid. This has been due to sensitivity bank-client

    relationship and the high administration costs and market frictions.

    Structured credit products have the capacity to provide pure exposure to credit risk. Furthermore, theyprovide the investor with the ability to trade credit in a liquid format with relatively low transaction

    costs.

    The use of credit derivatives allows the separation of credit and liquidity premiums on the credit-

    sensitive securities. For the traditional credit investor, this means that instead of investing in relatively

    illiquid corporate bonds, he can invest in highly liquid securities and overlay with credit derivatives,

    economically achieving the desired yield-enhancement effect but maintaining high liquidity. This is a

    major benefit for the liquidity-conscious ALM investor.

    Credit risk has low correlation with property and casualty risk. Therefore it makes a valuable addition

    to the investment portfolio of an insurance company.

    The [BAA 2004] outlines the market for credit structured products is comprised of the following

    products as follows:

    CDS Synthetic CDOs Index linked structures Credit linked notes Credit spread products Asset swaps

    Total return swaps Basket products Equity-linked products

    CDS take up to 51% of the market and are the building block of the credit market. Synthetic CDOs,

    index linked structures, some credit linked notes, basket products and credit spread products use single

    name CDS.

    CDS are short puts on credit, and thus can be straightforward described as yield-enhancement products.

    Index linked structures can be in delta one form or may be used as underlying and combined with a

    payoff structure. Asset swaps ant total return swaps are economically similar to the delta one payoff.Credit linked notes and credit spread products are similar to the equity structured products presented in

    Section 2.1. Basket products are similar to baskets of options, typically the options being single name

    CDS.

    Sensitivities of the CDO Equity Tranche

    [Thompson, Minh, Greenberg 2004] show that CDOs provide diversification to the credit inverstors in

    two ways:

    Exposure to credit risk with less interest rate risk than corporate bonds

    Leveraged exposure to credit since CDO tranches are options on the loss of the credit pool

    Realistic asset allocation and statistical studies are not feasible due to insuffiecient historical data

    Optimizing a portfolio of credit with a CVaR they show that including CDO tranches can expand the

    efficient frontier of a credit investor

    2.5 Hedge Funds

    The case of investing in hedge funds has been increasingly drawing the attention of institutional

    investors. While hedge funds have not been definitely classified as a separate asset class, structured

    products are available to meet the institutional investors interest and overcome the difficulties of

    investing directly.

    Two potential features make hedge funds attractive for an institutional investor: superior investment

    management and niche investment strategies that can profit from market inefficiencies.

    As an investment vehicle, hedge funds exhibit specific constraints:Limited liquidity

    No secondary market

    Long valuation and settlement cycle

    Low transparency

    Yet, these and several big blow-ups during the last decade have failed to cool the investors interest.

    As an investment vehicle, hedge funds exhibit higher return and higher volatility, potentially leverage

    and are exposed to gap risk

    3. The institutional investor

    3.1 Business environment and risk preferences

    Institutional investors are large investors who accumulate wealth capital, manage it and disburse it to

    match an uncertain liability stream. As long as the asset stream is greater than the liability stream there

    is a surplus, or vice versa, there is a deficit. As deficits accumulate, the company will experience

    deterioration of its financial position and may reach insolvency.

    The academic framework to modelling the behaviour of the investor uses utility functions. The CARA

    and the CRRA utility function families seem to be particularly popular as they have tractable

    optimization solutions. However, as [Clarkson] points out, the limitations of mathematical modellingof the risk perception of an individual may be outweighing the benefits.

    The utility functions approach is mathematically elegant and provides the basis for determining ht

    optimal investment weight in a portfolio of a risky and a risk-less asset. In the case of derivatives and

    structured products investments, the risk-averse investor then should naturally prefer capital protected

    products, due to their downside protection. The risk-loving investor should prefer yield-enhancing

    structured products, which active take on risk and receive a higher return. However, the institutional

    investor cannot be classified as risk-averse, risk-neutral or risk-loving.

    The institutional investor faces the problem of matching a certain liability stream. The stream may be

    of stochastic or non-stochastic nature. Furthermore, the institutional investor may face therequirements of various stakeholders. The investor is risk averse up to a certain threshold, yet beyond

    that maximizes expected profit. Risk aversion however in this case is not related to the preference of

    more wealth to less wealth. The institutional investor is first and foremost concerned with the

    avoidance of bankruptcy or regulatory action. I will call the amount of wealth below which the

    institutional investor may start experiencing increasing cost of capital due to bankruptcy concerns the

    minimum sustainability threshold. For a defined-benefit pension fund that has to provide a minimum

    guaranteed return on the beneficiaries assets, the minimum sustainability threshold is this minimum

    return. For a life insurance company it is the minimum guaranteed rate of return embedded in the life

    insurance products.

    Now, lets assume that the institutional investor can meet this requirement at a satisfactory level, forexample with a probability of 99% over a horizon of 3 years. Then for any budget above this level we

    cannot assume that the investor will be acting a risk-averse manner. Any budget above the minimum

    threshold has to be spent in a way that maximizes the firms value or the beneficiaries profit. That is,

    the institutional investor is expected to judiciously take risks and exercise professional expertise, and

    we can describe this behaviour more as risk-neutral rather than risk-averse. That is, the investor will

    expect constant additional return for each risk he accepts. Investing in a risk-averse manner in this case

    is detrimental to stakeholders, as it is equivalent to paying for double protection that is actually not

    necessary. This is further supported by the fact that any investor, be it risk-averse, risk-neutral or risk-

    loving benefits from diversification, assuming that assets that are not perfectly positively or negatively

    correlated exist.

    We might be able to justify even risk-loving behaviour, if the manager remuneration is positively

    dependent on the return of the. Indeed, it is more realistic to assume that the degree to which the

  • 8/8/2019 Deriv Survey

    33/42

    portfolio stakeholders can exercise control over the institutional investor and business and regulatory

    environment will be one of the determinants of qualitative utility function of the institutional

    investor.

    To summarize, the institutional investor:

    In this framework, the institutional investor benefits from the use of structured products as they helpme better:

    Hedge a liability stream and a minimum threshold level when hedge instruments are notavailable on the market

    Accept risks judiciously in order to earn return Diversify in order to manage risks

    The implications of this line of thought are that the institutional investor will invest in structured

    products, because they provide a flexibility that is not available in traditional assets and they isolate

    risks, so that the investor can take diversified or non-diversified views.

    3.2Institutional investors: readily invested in a structured product on the economy

    Structured products are not a new invention, but the development of financial theory has helped us

    understand better the ways we transact financially.

    In his groundbreaking work, [Merton] shows that the value of the equity and the bonds of a company

    can be represented as a long call and a short put option on the value of the firm. On the other hand,[Markowitz] first showed that an investor should invest in some combination of a risk-free asset and

    the market portfolio, with the optimal weights determined by the investors utility function.

    If we view the value of a stock index as a call option on the whole economy, and ignore cash for a

    while, the investor is actually holding a long call + risk-free bond. Any investor that has been invested

    in the traditional equity/risk-free bond/cash portfolio has actually been holding a structured-product-

    like portfolio.

    Let S represent the value of the whole equity market, p and c are a put and a call on the equity market

    (as represented by the stock index), and is the value of risk-free discount instrument, that pays K

    in time T, the implicit assumption being that the investor is interested in investing in a finite period of

    time T.

    rTKe

    Then the put-call parity holds

    rTKecSp

    +=+

    We see that the typical long-only equity plus government bond portfolio is actually the right-hand side

    of this equation. For an investor who also invests in corporate bonds, it is easily shown that he is

    actually holding delta-one like payoff on the whole investable company universe.

    Because the investor cannot directly access the true firm value of all investable companies, by holding

    a portfolio of zero-coupon bond, equities and corporate bonds, he has gained exposure to the aggregate

    investable firm value by creating a portfolio of 2 options and one zero-coupon bond - a structured

    portfolio payoff. (Figure 33)

    3.3 Structured products, indexation and the core-satellite framework

    The institutional investor manages its liability exposure by investing the available assets passively by

    indexing the assets or can try outperforming the market by either managing them actively or

    employing an outside active manager.

    Indexation is the construction of a portfolio that is designed to provide returns that match as close as

    possible a certain benchmark. Indexation is an improper name for a investing in a customized

    benchmark. An index aims to represent a market or a particular risk such as a style, sector etc. A

    benchmark tries to be representative of a management strategy, and there is no requirement to stick to

    a particular index. The index is expected the represent the pure systematic risk factor. Thus it supportsthe construction of a benchmark and is not a substitute for allocation. The benchmark may or, more

    often, may not be a readily available market index, and this creates the need for a synthetic index that

    will reflect the liability needs of the institutional investor.

    The three practical implementations of indexation:

    Pure indexation indexing the whole portfolio Enhanced indexation strategy this approach seeks to modestly outperform the index while

    essentially retaining the characteristics of the index

    Core-satellite strategy - indexing significant portion of the total capital and investing the non-index part in active alpha portfolios.

    Indexation is superior to active asset allocation in:

    Its ability to match a liability stream It avoids the problems of potential market impact of large changes in asset allocation It is more cost efficient in the meaning that fees are paid only for pure alpha and not for beta

    performance

    The satellites are generally of smaller size and are invested in a larger variety of investmentstrategies; this also provides a greater diversification benefit

    Delta-one exposure to the value of all

    investable companies

    Equity + Zero-coupon bond Corporate bonds

  • 8/8/2019 Deriv Survey

    35/42

    Major indexed investors are pension and trust funds. The benefits of indexation stand out in

    international equity investment, where significant additional costs and inefficiencies may significantly

    dent the performance.

    In the perennial discussion of passive vs. active asset allocation, structured products can be used as

    investment tools on both sides.

    On the one hand, they can provide exposure to pure risks, which if considered separate asset classes

    should be included in the portfolio of an institutional investor, due to their diversification benefits,

    such as credit, volatility and inflation. Alternatively they can be used to hedge risks which the investor

    is not willing to take.

    On the other hand, structured products can be used to gain exposure to superior investment

    management skills, to exploit niche strategies or to implement investment bets. Thus they can be

    directly applicable in an active investment management framework.

    The core-satellites framework which stands between the purely passive and the purely activeapproaches has recently gained prominence. The French government introduced this approach to

    manage part of the state pension fund. CALPERS, the largest pension fund employs it as well.

    The core-satellite framework has developed to overcome the natural mismatch between of the

    available investment classes, such as equities, bonds etc, and the liabilities of an institutional investor.

    35

  • 8/8/2019 Deriv Survey

    36/42

    Broad market indices are not appropriate benchmarks because they are not a natural hedge to the

    liability stream. This calls for a synthetic benchmark that replicates the liability stream.

    Securities with the required maturity or risk-return profile may be unavailable. Embedded minimum

    guarantee liabilities can be hedged either through investing in a zero-coupon risk-free bond with the

    same maturity, if such is available, or through dynamic replication. This presents a case to apply

    derivatives overlays or structured products that will provide timing and risk-return flexibility.

    An investment manager should not be paid for accepting beta risk, but only for the positive alpha that

    they generate. Alpha and beta risk and the remuneration paid for accepting them should be clearly split.

    Constraining the active managers with tracking error limits is suboptimal as it constraints the alpha

    around the benchmark. Then the risk budget is not fully spent on the alpha strategy. Active managers

    should be given more freedom to implement their investment skill and should not be imposed tracking

    error mandates that render them passive

    Below I present the approach of Calpers and approach in the core-satellite framework, Liability-Driven Investment. Structured products naturally fit in a core-satellite or enhanced indexation portfolio

    as satellites.

    Liability-Driven Investing

    Core portfolio, called Minimum Risk Portfolio, is invested in very low-risk or risk-free securities and

    closely matches the liability stream

    There is no consensus about structure of the core portfolio, yet generally discussed strategies are

    Government bond liability matching

    However longer-term maturities may not be available

    If investor chooses to roll-over shorter-term securities, he forgoes the long-term premium

    Cash + Swap liability matching

    Enter into long-term swap agreements

    Perfect replication at the cost of flexibility (liabilities may change over time)

    Customized benchmark: government bonds + swaps

    As satellites, the fund employs pure alpha strategies, targeting yield enhancement and diversification

    Portable alpha strategies, concentrated portfolios, credit risk etc

    4. Limitations

    Structured products are not an asset class. Structured products may allow access to one or several asset

    classes, but they are investment vehicles that do not carry original risk factor.

    For capital guaranteed products, capital guarantee typically applies only if the product is held until

    maturity.

    For some products there may be liquidity issues: There may not be a secondary market; secondary

    market may be illiquid.

    Fees, fees, fees hidden and obvious, nothing comes for free

    Mark-to-model risk, especially for longer maturity options

    As investment vehicles, structured products may suffer from performance transparency as it may be

    difficult to establish benchmarks.
