Liquidity is one of the main characteristics of securities in capital markets. Investors want
a certain level of liquidity so that they can buy and sell securities without incurring
significant losses. Therefore, investors want risk premium for securities that do not fulfill
adequate liquidity criteria. Economic theory suggests that liquidity and equity returns have an
inverse relationship. Investors demand higher returns from securities that have high liquidity
risk, while they are ready to receive lower return from securities that have higher level of
liquidity. Therefore, it can be said that importance of liquidity stems from the aspirations of
shareholder to obtain higher reward for the higher risk. It is generally agreed that liquidity can
influence asset returns. In recent years, liquidity has attracted
significant attention as a component of asset pricing models. In most of the studies, liquidity is considered as a risk factor
with reference to asset pricing. The return related to this risk factor is the risk premium and
investor expects to receive it as a result to taking that specific amount of risk. It is incorporated
in Capital Asset Pricing Model (CAPM) as extensions to capture the impact of missing
risk factors. Empirical literature identifies various proxies to capture the liquidity which
include bid-ask spread, turnover ratio, dollar value traded, etc. The role of liquidity in
explaining equity returns has been examined in various markets of the world, but there is no work,
to the best of our knowledge, with reference to Pakistan. Therefore, the prime objective of
this study is to explore the role of illiquidity premium in explaining equity returns in the
Karachi Stock Exchange (KSE). This study also examines the relationship between
illiquidity premium and returns of stylized portfolio. The stylized portfolios constructed and
examined in the study include size-sorted portfolios, BMR-sorted portfolios,
momentum-sorted portfolios, PE-sorted portfolios, and liquidity-sorted portfolios. This study uses turnover
ratio as a proxy for liquidity and extracts illiquidity premium through difference between
liquidity-sorted portfolios. This specific methodology is consistent with the conventional
method employed to determine the size premium and value premium. However, this study is a
first attempt in the context of Pakistan to employ this procedure for capturing illiquidity
premium.
