August is usually considered a weak month for stocks. This year, the S&P 500 is up about 3% with one trading day left.
That matters, because when August was positive and stocks were already up 10% to 17.5% for the year, the final four months gained in 10 of 11 past instances.
It’s a small historical sample, not a forecast. But it’s one reason September’s bad reputation may not tell the whole story this year.
