Risk-Return Tradeoff And The Behaviour Of Volatility On The South African Stock Market: Evidence From Both Aggregate And Disaggregate Data

The paper analyses the nature and behavior of volatility, the risk-return relationship and the long-term trend of volatility on the South African equity markets, using aggregate-level, industrial-level and sectoral-level daily data for the period 1995-2009. By employing dummy variables for the Asian and the sub-prime financial crises and the 11 September political shock, the paper further examines whether the long-term trend of volatility structurally breaks during financial crises and major political shocks. Three time-varying GARCH models were employed: one of them symmetric, and the other two asymmetric. Each of these models was estimated based on three error distributional assumptions.
