Midterm Year Pullbacks Have Been Followed by Double-Digit Gains

I’ve said it before, and I’ll say it again: it’s not the political party that matters, but the policies. Investors, I believe, are better served when they focus not on the partisan noise and headlines but the policies that bring about change.

I bring this up because we’re a little over 80 days from another midterm election. The S&P 500 closed at an all-time high on Thursday and is up more than 13% for the year. But between now and November 3 sits the stretch of the calendar investors like least.

So, I pulled up six decades of market data to see what that stretch has actually looked like.

September Has Earned Its Reputation. August Has Not

Using data going back to 1960, I found that only one month—September—has had a negative average price return over multiple time periods. Over the long term, it’s been down 0.76% on average, and over the short term, it’s been down 1.34%

September Remains the Market's Toughest Month

August is a different story. The eighth month has averaged a positive 0.26% going back to 1960 and a positive 0.16% over the past two decades. Its bad name comes from a handful of poor-performing Augusts in the 1990s and 2000s.

What’s interesting about September is that it’s not usually a down month. Since 1960, it’s finished lower 36 times out of 66, close to a coin flip. What sets it apart is how much it loses when it does. The declines have run deeper than in any other month.
