July begins NASDAQ’s worst four months but is also the seventh best performing NASDAQ month since 1971, posting a 0.9% average gain. Lively trading often accompanies the first full month of summer as the beginning of the second half of the year tends to bring an inflow of new capital.
This creates a bullish beginning, middle, and a mixed/flat final third. On average, over the last 21 years, nearly all of July’s gains have occurred in the first 13 trading days. Once a bullish day, the last trading day of July has had a modestly bearish bias over the last 21 years. In post-election years since 1950, July has exhibited a similar pattern to the recent 21-year period with some modest weakness just ahead of Independence Day.
