| description | Previous empirical tests of the Capital Asset Pricing Model (CAPM) in mature and
emerging capital markets focused on the premise that there is a positive linear
relationship between portfolio betas and portfolio returns. The CAPM predicts that
the expected return for any asset is a positive function of only three variables namely,
beta (the covariance of asset return and market return), the risk free rate and the
expected market return.
Earlier findings by Black, Jensen and Scholes (1972) and Fama and MacBeth (1973)
in the US stock markets generally found a weak but positive relationship between
portfolio returns and beta over the entire sample periods. However, this assertion was
seriously challenged by the findings of Banz (1981) and Fama and French (1992)
which evidence indicated the absence of a systematic relationship between beta and
portfolio returns. Further evidence indicated that other variables such as size of the
finn and the ratio of the book value of a finn's common equity to its market value seemed to do better than beta in explaining the cross-sectional variations in average
asset returns. Pettengill, Sundaram and Mathur (1995) offered a new interpretation of
systematic relationship and introduced a new methodology to test the CAPM, which
assumes a conditional relationship between portfolio returns and beta depending on
whether the excess market return is positive or negative.
The main objective of the study is to examine this conditional relationship between
beta and returns as proposed by Pettengill, Sundaram and Mathur (1995) to
Malaysian stock returns. To study this relationship, monthly data for a period of 15
years between January 1985 and December 1999 were used. The study also looked at
the impact of non-synchronous trading problem on the KLSE. In addition, the study
also examined the impact of portfolio size on the systematic and conditional as well
as unconditional relationships between beta and portfolio returns.
The results indicated that there was a very weak evidence of a significant risk
premium on beta when the unconditional relationship between beta and portfolio
returns was considered. When the sample was split into periods whether the excess
market return is positive or negative, there was a significant relationship between
portfolio returns and beta. The evidence also indicated that the size of portfolio had a
positive linear relationship with' the value of the cross-sectional coefficient under
conditional relationship. However, the results did not support any positive reward for
holding market risk during the sample period. |
