TRANSCRIPT
Ashok B. Abbott is an Associate Professor of Finance at
West Virginia University in Morgantown, West Virginia.
Professor Abbott received his MBA in Finance at Virginia
Polytechnic Institute and State University (VPI&SU) in
1984, followed by a Ph.D. in finance also at VPI&SU, in
1987. His Ph.D. dissertation title was "The valuation
effects of tax legislation in corporate sell-offs".
He has published extensively in scholarly research journals
and made presentations at national and international
conferences. He serves on the editorial boards of The
Business Valuation Review and The Value examiner. The
Small Business administration recognized Professor
Abbott as the Small Business Advocate-Journalist for the
year 2002.
His focus area of research and consulting in valuation is the
level of price adjustments (discounts/premiums)
appropriate for liquidity, marketability, and control
attributes of the interests being appraised.
Professor Abbott consults for valuation divisions of well-
known firms, such as Standard & Poor's, Duff & Phelps,
Willamette Management Associates, Houlihan Valuation
Advisors, among others. He has served as an expert
witness in the business valuation arena for 15 years. You

Size Effect Size effect, initially reported by Banz (1981) and
Reinganum (1981) has been researched extensively.
Research Indicates that smaller (measured by market value) ( Check with Roger on other measures of size)firms tend to exhibit higher returns than the levels predicted by the Sharpe Lintner capital asset-pricing model (CAPM).
Original Question by Banz
“It is not known whether size per se is responsible for the effect or whether size is just a proxy for one or more true unknown factors”.
Research Questions Q1. Is there a difference in returns among smaller and
larger firms?
Q2. Is there a difference in returns among low and high liquidity firms?
Q3. Is there a difference in returns among low and high liquidity firms within each size category?
Why do we care about liquidity Recent events in the financial markets have pointed
out how much the financial system depends on the ability to trade assets continuously.
The current failures in the Auction Rate Market demonstrate what happens when the market for an asset disappears. Even in the event of no underlying default securities become non-tradable.

Publicly Traded Equivalent Value
Capital Asset Pricing Model (CAPM),
Ibbottson premiums, or build-up rates
using capital market proxies provide
an estimate of the publicly traded
equivalent value (“PTEV”) of a
privately held company.
Liquidity Assumptions of the Publicly Traded Equivalent Value
Finance literature recognizes four dimensions of liquidity:
Width (availability of a large number of buyers) Depth (ability to absorb large volume) Immediacy (ability to complete the transaction
quickly) Resiliency (absorbing large volume of trades without
moving the price)
Time Varying Liquidity Liquidity conditions change rapidly.
Cost of Liquidity is a function of liquidity and volatility.
Low Liquidity and high volatility combine to increase the cost of liquidity.

Characterized by infrequent shocks in which the bottom drops out of previously well functioning market.
No bids, no asks. Fire-sale pricing.
Securities suddenly become “toxic waste”.
Episodic Illiquidity
Core Issue in Liquidity :Immediacy
Assumption: Market orders have immediate execution.
Reality: Small at -the -market transactions of high trading volume public securities approach immediate execution.
Large block transactions of thinly traded public securities are likely to occur off the floor or may need to dribble out.
Substantial execution delay and Liquidity discount are relevant to asset pricing.
Liquidity and Returns in Public markets
Research shows significant difference between returns on liquid and illiquid publicly traded securities.
Brennan and Subrahmanyam (1996) show the return difference of the most liquid and least liquid shares on the New York Stock Exchange is 6.62% per year.
This difference roughly translates to a discount for lack of liquidity (DLOL) of 35.5%.
Liquidity and Asset Prices
Liquidity is Priced
Liquidity is Systemic
Liquidity varies over time
Liquidity Premium is a major factor in Asset Pricing

Measuring Liquidity
Liquidity Measure (l) takes in to account both the trading volume and shares outstanding. It is a natural log transformation on Turnover measure.
Given
The stock issued and outstanding at Day 1 is S1
Trading Volume for one day is V1
The stock still in hands of original owners at beginning of Day 2 is S2 = S1- V1
Assuming that the rate of deal flow is constant (l) at day 1
S2 = S1 e- l
Or l = Logn (S1) - Logn (S2)
Empirical Questions need Empirical Analysis
Data Sample Used
Centre for Research in Security Prices (CRSP) equities
Data provides
Daily Price ( High Low Close Bid Ask), Return, Volume, and Shares Outstanding among other data
Sample period 1926-2011
Covers periods of panic and Euphoria
80 Million Plus daily Observations
Three Million Plus monthly observations
Migration Issue Addressed Fama and French suggest that ‘Migration’ is a significant
issue in size based studies. Firms tend to migrate to higher size deciles following positive returns or lower deciles/ get delisted following negative returns.
We form Portfolios based on MONTHLY levels of market value and liquidity. Firms with IPO or delisting during the month are excluded from the sample. This results in reassigned monthly portfolios.
Removing Outlier Effect
The data used in this analysis are winsorized at 1% level.
Values above the 99th percentile value are set to the 99th percentile value.
Values below the 1st percentile value are set to the 1st percentile value.

Liquidity Costs are not trivial Liquidity Costs significantly reduce any gains
associated with small stock premium and need to be accounted for.
Small stock premium may be a statistical artifact for annual holding periods in view of the substantial illiquidity observed.
Conclusion: Size and Liquidity are both important in explaining asset returns.
We have illustrated the role of liquidity in explaining the returns on assets across time.
Liquidity differences can explain a very substantial part of the differences in returns between small and large as well as liquid and illiquid assets.
Size and liquidity premiums are not mutually exclusive.
