A rare divergence between the Dow Jones Industrial Average and the Nasdaq composite points to a 67% chance that U.S. stocks will enter a bear market within three months. Over seven trading sessions through June 25, the Dow rose 0.5% while the Nasdaq composite fell 5.0%, a 5.5 percentage-point spread that has occurred only about 1% of the time since 1971. Historically, bear markets have followed such wide divergences 66.9% of the time within three months, compared with a 24.8% baseline bear-market frequency. The current divergence is a nearly three-sigma event, suggesting the recent Nasdaq drop may not be a healthy rotation. Analysts caution that the signal is not a guarantee, but advise monitoring the spread and considering hedges if it persists.
