July 2026 is approaching its final stretch on a somewhat somber note for Wall Street investors. As of the latest trading sessions, performance data for the SPY ETF (tracking the S&P 500) reflects a monthly decline of roughly 2.32%.

This pullback is particularly notable given that July is historically one of the strongest months of the year, boasting a multi-year average gain of 2.65%. If this negative trend holds through the final closing bell of the month, it will mark a shift from the strong momentum seen in April and May, leaving the market in a cautious stance heading into late summer.

Historical Trends and Seasonality

A broader look at monthly returns provides context on the seasonal dynamics of the S&P 500 over time. Historically, July benefits from strong quarterly earnings reports and favorable seasonal capital flows—delivering positive gains of 3.27%, 1.21%, and 2.30% in 2023, 2024, and 2025, respectively. The current weakness suggests that macroeconomic pressures and financial headwinds are, for now, overriding typical seasonal patterns.

Despite July’s decline so far, the year-to-date picture still shows relative resilience. The S&P 500’s cumulative return for 2026 sits at 7.54%, anchored by an impressive 10.51% surge in April and a 5.26% gain in May. The data indicates that while growth has moderated compared to the strong years of 2023 and 2024, the index retains a comfortable buffer for the year.

Preparing for August and September

The breakdown of July’s usual bullish trend—should it hold through the remaining sessions—is drawing close attention from analysts due to its timing on the financial calendar. Historically, the upcoming months are among the weakest of the year:

August: Posts an average historical return of -0.13%

September: Stands as the historically weakest month of the year, with an average return of -0.52%

Recent years have seen sharp volatility during this period; for instance, the index plummeted 9.24% in September 2022 and fell 4.74% in September 2023. As a result, market participants are closely monitoring incoming macro data as July wraps up, watching whether this month’s dip signals broader seasonal weakness ahead or merely a localized technical correction.

Looking Toward Year-End

Market activity in these final days of July is shifting institutional focus toward the second half of the year. Historically, following the late-summer lull, the stock market tends to rebound in October (average return of 2.27%) and November (average return of 3.09%).

For now, investors remain hyper-focused on central bank monetary policy decisions and corporate earnings guidance as the month closes out, weighing whether full-year returns will align with historical averages or if ongoing market pressures will require further portfolio adjustments.
