S&P 500 Death Cross (50-Day Below 200-Day MA)
The most overhyped technical signal in finance
A death cross occurs when the 50-day moving average crosses below the 200-day moving average. Despite dramatic media coverage, the signal's predictive power is weak — it often fires AFTER most of the decline has already occurred.

What history says
Editorial commentary written by ALAN analysts. Figures cited below are analyst-authored context — they are not derived from the chart above and may reflect different windows or sources.
Moving averages are inherently backward-looking. By the time a death cross forms, the market has typically already fallen 10-15%. The signal confirms what already happened.
Since 1950, roughly 60% of death crosses were followed by a rally back above both MAs within 3 months. Selling on the signal would have been wrong more often than right.
When CNBC runs 'Death Cross Forming' headlines, this chart shows clients the actual track record. It defuses panic driven by technical jargon.
A death cross is a headline event, not a portfolio event — with roughly 60% of signals reversing within three months, trading on it has been wrong more often than right. Use the media attention as a prompt to confirm your plan doesn't hinge on technical triggers, and limit any action to an ordinary drift check against your targets.
