The S&P South Africa 50 represents the South African equity market by selecting 50 of the largest companies listed on the Johannesburg Stock Exchange, including both South African and foreign-domiciled firms. To reduce risk from large exposures, no company can account for more than 10% of the index weight at each rebalance.
In comparison with the often used FTSE/JSE Top 40, the S&P South Africa 50 provides broader coverage and greater diversification, which contribute to its historically lower volatility and higher risk-adjusted returns.
