Why Trading Day 137 Marks the Start of the S&P 500’s Cruelest Season

The article discusses seasonal weakness in the U.S. stock market, focusing on the S&P 500’s tendency to struggle between trading day 137 and trading day 197, roughly July 21 to Oct. 14 this year. It notes that August and September are historically the only two calendar months with average declines, and late summer often sees lighter news flow and weaker trading. The seasonal pattern is not guaranteed, but when it does produce declines, the losses have historically been larger than the gains in positive years. The piece frames the setup as a coin toss, but advises investors to plan ahead for possible weakness by considering cash hedges, downside triggers, or defensive strategies such as inverse ETFs, futures, or options. Overall, the article is cautionary for equities, especially broad U.S. market exposure.
