As October begins, the stock market is experiencing heightened volatility, a trend historically associated with this month. According to Bespoke data, the S&P 500's average intramonth peak-to-trough decline of 4.6% is the largest of any month since 1945. This year, the volatility is compounded by factors such as election uncertainty, heightened Mideast tensions, and a dockworkers strike. Historically, October tends to be a weaker month for stocks, especially in election years, with the S&P 500 down 31 out of 53 times, averaging a decline of 0.4%. Volatility is also 34% above average compared to other months. The Jewish holidays of Rosh Hashanah and Yom Kippur also play a role, with some investors following the 'sell Rosh Hashanah, buy Yom Kippur' strategy. Despite these challenges, some analysts believe that October's weakness may present opportunities for year-end gains.
