Summer Rally Fading—Historically Weakest of All
Using Stock Trader’s Almanac definitions (page 76 of 2026 edition), the Summer Rally runs from the DJIA’s closing low in May or June to its subsequent Q3 closing high. As of the close on July 21, DJIA’s Q3 closing high was 53055.91 on July 6 and its May or June closing low was on May 4 at 48941.90 yielding a modestly below average 8.4% summer rally so far this year. Applying the same parameters to S&P 500 and NASDAQ, results in summer rally gains of 5.2% and 4.8% respectively. Also, below historical averages.
As the accompanying chart shows, this seasonal advance can deliver solid gains but historically, it has also been the weakest of the four major seasonal rallies. That makes the current market particularly interesting. Summer momentum can create opportunities, but history also suggests investors should pay close attention as July gives way to the traditionally volatile months of August and September.
This is exactly where seasonal market intelligence can give investors an edge. Stock Trader’s Almanac has been tracking these recurring patterns for decades, helping traders and investors identify when the market tends to perform best and when caution may be warranted.
The Summer Rally may have more room to run, but the seasonal clock is ticking. Knowing what history says could happen next may be just as important as knowing what is happening now.
