Purpose – Estimates of systematic risk or beta are an important determinant of the cost of capital. The standard technique used to compile beta estimates is an ordinary least squares regression of stock returns on market returns using four to five years of monthly data. This convention assumes...

Purpose – The purpose of this paper is to examine the nature and extent of instability of capital asset pricing model (CAPM) beta in a small emerging capital market. Design/methodology/approach – Inter-period as well as intra beta instability are examined. Inter-period instability is...

Purpose – The purpose of this paper is to investigate the forecasting power of the conditional relationship between beta and international stock returns. Design/methodology/approach – Using the market model, the individual betas for each country in the sample are estimated by ordinary least...

Purpose – The purpose of this paper is to examine the shocks to firm's beta around the event of addition or deletion from the S&P 500 index. Design/methodology/approach – The total derivative of beta and Campbell and Vuolteenaho decomposition of beta methodologies are used, on monthly and...
