Autumn: The Witching Season

SUMMARY

  • September and October historically have been difficult months for the market.
  • However, markets tend to rally in the winter, especially in election years.
  • Riverfront remains positive on the fundamental and technical backdrop for stocks.

Buckle your seatbelts…we are now past Labor Day and thus ‘the witching season’ starts. No, not Halloween…but rather the spooky market anomaly that is September. According to a NDR Research study of 656 months starting in December 1969, September has been historically the worst month of the year in terms of stock market returns. This is true both in terms of percentage of positive outcomes (September is positive only 44% of the time - red bar in Chart 1, below) and in average return, as September is the only month of the year that averages a negative return. Adding insult to injury, October also tends to be a volatile month that witnesses the most market lows.
