Studies Find Active Large-Cap Funds Closely Track Nifty 50, Alpha Declines Post-2010
Recent studies show that active large-cap mutual funds closely mirror the Nifty 50 index, with about 90% overlap in sector allocations, especially among the largest funds. This limited deviation reduces diversification benefits and restricts fund managers' ability to generate alpha returns. Performance data indicates that while large-cap funds outperformed the Nifty 50 TRI before 2010, their alpha advantage has declined and turned negative post-2020, partly due to regulatory mandates limiting investment scope.
