The death cross is a chart pattern indicating the potential for a major selloff. The death cross appears on a chart when a stock’s short-term moving average crosses below its long-term moving average. Typically, the most common moving averages used in this pattern are the 50-day and 200-day moving averages.


What's a Death Cross?

What is a Death Cross?

The death cross indicator has proven an accurate predictor of the most severe bear markets of the past century: 1929, 1938, 1974 and 2008. Investors who got out of the stock market at the start of these bear markets avoided large losses that were as high as 90% in the 1930s. Because a death cross is a long-term indicator, as opposed to many short-term chart patterns such as the doji, it carries more weight for investors concerned about locking in gains before a new bear market gets underway. An increase in volume typically accompanies the appearance of the death cross.

Here is an example of a death cross on the S&P 500 in December of 2018:


The death cross name derives from the X-shape created when the short-term moving average descends below the long-term moving average. Historically, the pattern precedes a prolonged downturn for both the long-term and short-term moving averages. The death cross is a signal that short-term momentum in a stock or stock index is slowing, but the death cross is not always a reliable indicator that a bull market is about to end. There have been many times when a death cross appeared, such as in the summer of 2016, when it proved to be a false indicator. Those who got out of stocks during the summer of 2016 missed the sizable stock market gains that followed throughout 2017. The 2016 death star example was in fact occurring during a technical correction of around 10%, which is oftentimes seen as a buy opportunity known as buying on the dip.

Following is an example of two death crosses that occurred for Facebook Inc. (FB) stock in 2018. After the first one in April, the stock turned around and began an extended rally. The second one in September, however, signaled a prolonged bear market for the stock.


Looking back over the most punishing bear markets of the past century, it seems the death cross holds up best once the market has already lost 20% of its value. In those instances, investors who fled stocks minimized their losses. But for smaller corrections of less than 20%, the temporary appearance of the death cross may be reflecting losses already booked, and thus indicates a buying opportunity.

What is a Golden Cross?

The opposite of the death cross occurs with the appearance of the golden cross, when the short-term moving average of a stock or index moves above the long-term moving average. Many investors view this pattern as a bullish indicator. The golden cross pattern typically shows up after a prolonged downtrend has run out of momentum. As is true with the death cross, investors should confirm the trend reversal after several days or weeks of price movement in the new direction. Much of the process of investing by following patterns is self-fulfilling behavior, as trading volumes increase with the attention of more investors who are driven in part by an increase in financial news stories abut a particular stock or the movement of an index.
