The history of this market’s bad-breadth signal points to risks ahead

AI SUMMARY

# Summary The stock market is displaying a breadth signal—where fewer stocks are driving gains while most others lag—not seen since the dot-com bubble, historically a warning sign of potential market correction or reversal. This deteriorating breadth suggests that despite major indices reaching new highs, underlying market health is weakening, creating elevated risk for investors who may be exposed to the broader market beyond the handful of outperforming mega-cap stocks.
