Othman Yong

Abstract


This paper attempts to explore the nature of price changes for the Malaysian Stocks. A non-parametric test called the Kolmogorav-Smirnov one sample goodness-of-fir was used to determine whether or not the price changes of the Malaysian stocks conform to the normal distribution. This test proved conclusively that the price changes of the Malaysian stocks are non-normal, thus substantianting the results of tests performed on other stock markets in the developed countries. In addition, statistical measures such as mean, standard deviation, skewness and kurtosis were used to further describe the distributional nature of the price changes for these stocks.
