October Futures Seasonality: The Bear Killer
September is finally over. After another bad month for stocks (not unusual) and bonds (atypical), we now arrive at a crucial turning point in the markets, at least from a seasonality perspective. October has been called “the bear killer” for a good reason.
Not only does it kick off the usual rally into the end of the year (the S&P 500 has rallied 5.5% in the fourth quarter over the past decade), but 7 of the 18 bear markets since World War II have ended in October. And with bearish sentiment reaching an important threshold, October may indeed be another "bear killer."
