Narrow market leadership could matter to retirement savers, index-fund investors, and households whose portfolios depend on broad equity gains. If returns remain concentrated, many investors may see weaker results than headline index levels suggest, potentially widening gaps between those owning winning stocks and those holding diversified baskets. Financial advisers and plan sponsors may face more questions about diversification and risk. This is a market-structure observation, not a prediction; outcomes may vary as breadth shifts.
