But a monthly gap is often built on one or two extreme years — the table above shows it: look at the spread, not just the average. Seasonality only means something when it has a cause (selling season, earnings calendar, year-end tax effects); with no identified cause, it's probably noise.

Do S&P Global's quarterly earnings move the stock?
July — when S&P Global reports quarterly earnings — has been its best month over 14 years (+5.7% on average, up 79% of years). Earnings are a known driver of moves. ⚠️ This is a past tendency over a short history, not a rule. Use it as context, never as a buy plan.
Why does S&P Global stock often rise in July?
July has averaged as its best month over 14 years (+5.7%, up 79% of years). This month covers S&P Global's quarterly earnings release — a known driver of moves, and over this history it has tended to push the stock higher.
Why is S&P Global stock weaker in September?
September has averaged as its weakest month over 14 years (-2.9%, up only 38% of years). No clearly established recurring seasonal driver explains this month — it's a statistical tendency over 14 years of history, not a prediction.
Is there a best month to invest in the stock market in general?
There's no universal rule: every stock has its own seasonality. For SPGI it's July (+5.7% on average over 14 years) — another stock will look completely different. The calendar effects people cite ("sell in May", the year-end rally) are market-wide averages, not laws: on SPGI, November is the most consistent month (85% positive years). We also rank all 12 months for the whole market.
Does stock seasonality actually work?
Careful. A month that rose 14 times out of 14 can simply be chance: with 12 months and a dozen years, patterns appear naturally even in random data. Seasonality describes what happened; it doesn't explain why and predicts nothing. Treat it as context, never as a standalone buy signal.
