We examined the S&P's performance during the first nine months of 2024. The index finished September with an impressive 20.8% increase, having only faced one losing month in April, which saw a decline of 4.2%. Notably, all seven rolling quarters during this period were positive, comprising the months from January to March, February to April, and so on. This remarkable performance places 2024 among only 15 years since 1930 that experienced both a gain of over 10% in the first nine months and no negative rolling quarter within that same timeframe. It's significant to note that all instances occurred after 1950.
A closer look at the historical data from the previous 14 cases reveals a pattern: while there tends to be some weakness in the second week of October, this is often followed by an "End of Year" rally starting around October 27. In fact, 13 out of the 14 instances recorded were positive from that date through the end of the year, with only a minor fractional loss occurring in 1964. Worth noting, four of the last five years have also seen positive performances during the period from October 7 to 15.
