Only 18 of 100 U.S. public firms survive 40 years - MSIM

Morgan Stanley Investment Management research finds only 18 of every 100 U.S. public companies remain listed after 40 years, highlighting high corporate turnover in public markets. The finding implies significant index churn and concentration risk for benchmarks such as the S&P 500, which can affect passive fund composition, long-term portfolio planning and the persistence of market leadership. Investors and index-linked products may face recurring rebalancing and reward incumbents, underscoring the importance of diversification and active evaluation of long-term holdings.
