FAnews featured insights from George Tsinonis, Head of Investment Analytics at RisCura, in an article examining market concentration, diversification and the role of benchmarks in assessing investment performance. 

George highlights the risk of relying on benchmarks that do not reflect the market conditions investors actually face. The article also references new analysis by RisCura showing how benchmark construction can materially affect reported performance and volatility across African equity markets, reinforcing the need to look beyond headline index returns when assessing diversification and portfolio outcomes.
