Abstract
This study is an attempt to measure volatilities among regional stock markets and to establish a relationship between stock returns and volatility, and to rank these markets with respect to volatility. For this purpose, six markets are considered i.e. KSE1 00, Sensex, Nikkei225, Hangseng, Shanghai and Kospi. Indices data consist of daily observations from January 2 001 to August 2 008. As a primary investigation, time series graph consists of historic data which has been observed depicting high correlations and a heteroskedastic patron (volatility) among the markets over the sample tenure which then formally measured and ranked by applying descriptive model of standard deviation followed by coefficient of variation which reveals that KSE has 66.23% volatility and 0.1 0% average return followed by Sensex, which has 63.39% volatility and 0. 070% average return. Nikkei has, however, 22.19% volatility and a negative average return of 0. 0024%. Thereby a direct relation between volatility and stock return is established. To further validate descriptive models, an inferential statistics model i.e. Bartlett s test is applied to investigate that there is statistically significant difference among the volatilities experienced by these stock markets and the result is significant even at 0.1% significance level.
