This rare buy signal could soon flash for stocks

It’s fired just 16 times in 50 years, and the rallies that followed were pretty stellar.

This Rare “Buy” Signal Could Soon Flash For US Stocks

With so much economic uncertainty ahead, you might be wary about this year’s stock market rebound. But there’s a signal brewing that could give you more confidence in the rally.

The signal works like this: whenever the 21-week exponential moving average (EMA, yellow line) crosses *above* the 50-week simple moving average (SMA, blue line), it tends to suggest a strong uptrend ahead for the S&P 500. Historically, when it’s happened, you’d have been better off in the market than out. I’ve explained how moving averages work [here](https://finimize.com/content/Q29udGVudFBpZWNlOjUwMTA=/how-to-use-moving-averages-trading-and-investing?), but the gist of it is that the 21-week EMA is more reactive to recent price action. So when it crosses above the 50-week SMA, as it’s done here wherever you see a line of gray dashes, it shows strong momentum from buyers.

I’ve backtested the signal’s results since 1975 and here’s what I found. Of the 16 times it fired, 13 have led to S&P 500 rallies of at least 20%, with six being greater than 40%, and two being greater than 100%. Now, the time taken to reach those highs varies a lot, but the average was about two years. So if you like those stats, you might want to see the index hold steady for now – that way the cross is a lot more likely to happen. You also might want to add the two moving averages to your own S&P 500 chart in TradingView (you can learn how to do that [here](https://finimize.com/content/Q29udGVudFBpZWNlOjUwMTA=/how-to-use-moving-averages-trading-and-investing?)), so you can consider buying the **SPDR S&P 500 ETF Trust** (ticker: [SPY](https://www.ssga.com/us/en/intermediary/etfs/funds/spdr-sp-500-etf-trust-spy); expense ratio: 0.095%) on the first Monday morning *after* the cross.
