The macroeconomic determinants of South African sectoral returns: Evidence from Bull and Bear Regimes

Abstract

The Adaptive Market Hypothesis (AMH) allows for a re-evaluation of the relationship between macroeconomic variables and stock market returns, acknowledging that this relationship is time-varying and asymmetrical. This study investigates the impact of macroeconomic factors on the Johannesburg Stock Exchange (JSE) sector returns under varying market conditions from January 2008 to December 2024. Using a Markov regime-switching model, the findings show that macroeconomic effects on sectoral returns are regime-dependent and time-sensitive. In bullish markets, inflation growth has a significant negative impact on Industrial sector returns, but no significant effect during bearish regimes. For the Financial sector, inflation and money supply growth negatively affect returns, while the real effective exchange rate growth has a positive impact. In the Resource sector, all macroeconomic variables significantly influence returns during bearish conditions, with inflation growth showing a notable negative effect. Overall, JSE sector returns exhibit bull and bear market dynamics, and the influence of macroeconomic variables is neither uniform nor static aligning with the AMH framework.
