Abstract
The intention of the study was to broaden the knowledge and understanding of herd mentality on the JSE 40. Herd behaviour has the potential to destabilise and deteriorate financial markets, and a better understanding of this behaviour could minimize investment loss. Therefore, the study examined herd behaviour in terms of various idiosyncratic volatile stocks and different industry sectors using a dispersion-based model. The study also investigated whether or not Chinese market conditions influenced herd behaviour regarding those stock portfolios. The results suggest that fully and partly diversified portfolios tend to show evidence of herd behaviour. However, Chinese market conditions affect each stock portfolio differently. For example, the Industrial Portfolio Index was influenced by Chinese market conditions across all tranquil and turbulent periods. Meanwhile, other portfolios were only influenced by long tranquil or extreme volatile periods in the Chinese market. Interestingly, the Banking sector was the only stock portfolio that was not influenced by the Chinese market. Perhaps investors can use this knowledge to enhance their future portfolio returns.
