The Q1 2013 Managed Volatility Performance Paradox

What is the Paradox?

The Global Managed Volatility strategy aims to create a 100%

equity portfolio with minimum volatility within the MSCI World

universe. This strategy uses quadratic optimization in order to

produce the minimum ex ante volatility with the minimum set

of other constraints.

One major feature of the strategy is the low beta. This is a direct

consequence of the minimum volatility tilt. The typical

ex ante beta of the strategy is 0.6, which means that, according

to the CAPM theory, the excess return of the strategy should

be equal to 0.6 times the excess return of the market, i.e. the

MSCI World index. As such, the strategy is intended to offer

some downside protection in exchange for limited participation

in market rises.

However, from 31 December 2012 to 30 April 2013 the

performance of the Global Managed Volatility strategy has been

+16.31% versus +11.35% from MSCI World, outperforming the

benchmark by +4.96%.

Is there a paradox that the managed volatility strategy

has outperformed the benchmark when the benchmark

performance has been so high over the period, and when the

beta of the strategy is supposed to be much lower than the beta

of the benchmark? We investigated further.

Where does the Managed Volatility Paradox Come From?

It appears that the current characteristics of the managed

volatility strategy (as described in Figure 1) are in line with the

general description of the strategy, notably a low absolute risk,

a low predicted beta (less than 0.7) and a high tracking error

(more than 5%).

The absolute risk is much lower and this is the first objective

of the strategy. The beta is significantly lower at 0.65 and this

contributes to the high predicted tracking error of 6.0%.

The factor exposure supports this analysis.

SSgA CAPITAL INSIGHTS | Q1 2013 MANAGED VOLATILITY

The largest factor difference by far is the volatility exposure.

Here the managed volatility strategy is underexposed at

-0.54 versus -0.11 for the benchmark.

To understand the current outperformance—outperformance

obtained while the strategy is in line with our expectations in

terms of risk profile—we ran a performance attribution analysis

by sector. In fact the main driver of the overperformance over

the quarter is mostly the difference in sector distribution

(detailed in Figure 3).

Logically, the managed volatility strategy is actively concentrated

in the less volatile sectors such as Consumer Staples and

Utilities and is actively underweighted in the most volatile

sectors such as Financials and Energy.

It appears that the sector dynamics during the quarter resulted

in a flight to quality and to underexposure to volatility at a time

when the most volatile sectors—such as Materials and Energy

and Technology—have significantly underperformed and

the less volatile sectors—such as Healthcare and Consumer

Staples—have overperformed.

SSgA generally delegates commodities management for separately managed accounts to SSgA FM, a wholly owned subsidiary of State Street and an affiliate of SSgA. SSgA FM is registered as a commodity trading advisor (“CTA”) with the Commodity Futures Trading Commission and National Futures Association.

This communication is not specifically directed to investors of separately managed accounts (SMA) utilizing futures, options on futures or swaps. SSgAFM CTAclients should contact SSgA Relationship Management for important CTA materials.

This document provides summary information regarding the Strategy. This document should be read in conjunction with the Strategy’s Disclosure Document, which is available from SSgA. The Strategy Disclosure Document contains important information about the Strategy, including a description of a number of risks.

A large part of the 4.96% overperformance, 3.92%, comes from

the sector allocation and only a residual part, 1.04%, comes

from the selection effect. Thus, this overperformance would

have been replicated by any active sector funds that took this

defensive allocation during the quarter, irrespective of a low

volatility stock picking requirement.

Finally, the historical evolution of the Managed Volatility

Strategy’s value and momentum factors, since 2007, is shown

on Figure 4. From 2009 to 2011 the exposure to value was

positive. This can be interpreted as indicating that the Managed

Volatility Strategy was inexpensive relative to the value factor.

The exposure to value became negative in 2012 and 2013.

This could be interpreted as indicating that the Managed

Volatility Strategy is now expensive relative to the value factor.

Conclusion

The managed volatility strategy shows all the characteristics

of a low volatility strategy from an ex ante volatility (lower than

the volatility of the market), beta (lower than the one of the

market) and factor exposures (largely underexposed to

volatility factor) perspective.

The first quarter overperformance comes largely from the sector

allocation. It seems that the defensive sectors have largely

overperformed the cyclical sectors during the quarter.

It appears that a low beta strategy such as the managed

volatility strategy can significantly outperform the benchmark

even when the market is rising. Investors should bear in mind

not only the expected return of the strategy that is associated

with the beta, but also the absolute risk (low) and relative risk

(high) vis-a-vis the benchmark. On the other hand, however,

investors should be aware of the source of this overperformance

and should realise that being underexposed to volatility is now

becoming more expensive (in the sense of the value factor) than

it was before.
