As if September isn’t bad enough, to add insult to injury, it ends with what has historically been one of the most losing days of the year for the S&P 500.  The table below is from our annual expanded edition of the Bespoke Report that we publish at the end of each year, and it lists the ten days where the S&P 500 has most consistently traded down on the day.  While March 30th has traditionally been the day where the S&P 500 has been up the least, 9/30 is tied for fifth at 38%.  Since 1945, the S&P 500 has declined an average of 0.15% (median: -0.25%) with positive returns just 38% of the time on 9/30.  While the long-term performance of the S&P 500 on the last day of September has been poor, in recent years it has been even worse.  In the current bull market, if the stock market has been open on 9/30, it has traded down.  At least there’s only one day left in September after today!
