Historically, the Dow has gained an average of 24.1% from September 30 of the mid-term election year to September 6 of the pre-election year. This means that nearly two-thirds of the Dow’s four-year gain (24.1% of 36.7%) comes in less than one-quarter of the time. That’s a pretty stunning stat.
After September 6 of the pre-election year, the Dow has historically pulled back 5.2% to May 29 of the election year. After that, it puts on a nice 23.2% climb to August 3 of the post-election year. Then trouble starts. After August 3, the Dow then pulls back 5.6% and we’re back at our starting point, September 30th of the mid-term election year.
