Death Cross

A death cross is a chart signal that occurs when a shorter-term moving average crosses below a longer-term moving average, classically the 50-day dropping below the 200-day. It shows that recent average prices have fallen beneath the longer-run average, which traders interpret as confirmation that an uptrend has broken down and a sustained downtrend may be developing. Its bullish opposite is the golden cross.

For example, if Bitcoin declines for several weeks after a long rally, its 50-day moving average will flatten and turn down; when it slips below the 200-day moving average, headlines typically announce a death cross, and trend-following funds may reduce exposure or avoid new long positions until the averages realign.

Despite the dramatic name, the signal's track record is mixed. Because both averages are built from past prices, the cross often appears well after the bulk of a decline has already happened, and in volatile crypto markets some death crosses have occurred near local bottoms just before recoveries. A common misconception is that a death cross predicts a crash; it confirms weakness that has already occurred, and experienced traders treat it as one input about trend condition rather than a sell trigger on its own.
