Stocks often drop in September — but many investors shouldn’t care
September historically hasn't been kind to stock investors.
Since 1926, U.S. large-cap stocks have lost an average 0.9% in September, according to data from Morningstar Direct.
September is the only month during that nearly century-long period in which investors experienced an average loss, according to Morningstar. They saw a profit in all other months.
For example, February saw a positive 0.4% return, on average. While that performance is the second-lowest among the 12 months, is still eclipses September's by 1.3 percentage points. July reigns supreme with an average return of almost 2%.
The monthly weakness also holds true when looking just at more recent periods.
For example, the S&P 500 stock index has lost an average 1.7% in September since 2000 — the worst monthly performance by more than a percentage point, according to FactSet.

For example, the 10 best trading days by percentage gain for the S&P 500 over the past three decades all occurred during recessions, according to a Wells Fargo analysis
