3. Research Questions
Q1. Is there a difference in returns among smaller and
larger firms?
Answer
Q2. Is there a difference in returns among low and high
liquidity firms?
Answer
Q3. Is there a difference in returns among low and high
liquidity firms within each size category?
Answer
4. Size Effect
Size effect, initially reported by Banz (1981) and
Reinganum (1981) has been researched extensively.
Research Indicates that smaller (measured by market
value) firms tend to exhibit higher returns than the
levels predicted by the Sharpe Lintner capital asset-
pricing model (CAPM).
5. 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”.
6. Liquidity Effect
Large Body of Academic Literature as well as the
recent Episodic Illiquidity amply illustrate that there
is a very substantial Cost associated with lack of
liquidity
Business valuation profession has generally
incorporated lack of liquidity in to the Discount for
Lack of Marketability.
7. Intersection of Size and Liquidity
Is size is just a proxy for the
true unknown factor-
Liquidity?
8. 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.
9. 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)
10. Liquidity and Asset Prices
Liquidity is Priced
Liquidity is Systemic
Liquidity varies over time
Liquidity Premium is a major
factor in Asset Pricing
11. Measures of Liquidity
Half Life
(Average Liquidation period)
Bid Ask Spread
(Ask-Bid)/Ask
Trading Cost
(Holding Return-Trading Return)
Price Impact of Trading
(Amivest ratio)
12. 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)
13. 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
14. 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.
15. 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.
