Abstract

ABSTRACT This paper employs quantile autoregression to investigate the influence of ‘market size’ and ‘industry’ effects on the South African equity market volatility response to return shocks. It is now well documented that equity market volatility exhibits asymmetric response to positive and negative return shocks. This paper provides empirical evidence which shows that the South African equity market asymmetric volatility response is significantly a large company phenomenon and with the exception of the Resources 10 and Financials 15 Indices, there is generally no volatility asymmetric response heterogeneity at the sector level. These results have important implications for investors and fund managers in relation to portfolio construction, risk management and optimal equity risk premium determination.

基于分位数的南非股票市场风险回报动态分析

摘要本文采用分位数自回归研究了“市场规模”和“行业”效应对南非股票市场波动对回报冲击的影响。现在有充分的证据表明，股市波动对正回报冲击和负回报冲击表现出不对称的反应。本文提供的实证证据表明，南非股票市场的不对称波动响应是一个明显的大公司现象，除了资源10指数和金融15指数外，在行业层面一般不存在波动不对称响应异质性。这些结果对投资者和基金经理在投资组合构建、风险管理和最优股票风险溢价确定方面具有重要意义。
