July: Alphabet's standout month
July has averaged +8.09% with a median of +8.88%, so this isn’t a few outliers: GOOGL rose in 13 of 15 Julys. Alphabet has typically reported second-quarter earnings in the second half of July, which may be part of the reason. October (+4.58%) and May (+3.52%, median +5.78%) are next.
June looks weak, but the window starts mid-month
June is one of GOOGL’s weakest months, rising in only 6 of 15 years. Yet the window from June 17 to July 17 rose in 15 of 15, averaging +6.58%. The strength begins in the back half of June, which a monthly table can’t show. That’s why exact date windows are more useful than calendar months.
The most reliable GOOGL seasonal windows
| GOOGL window | Avg return | Rose in (15y) | Worst year |
|---|---|---|---|
| Jun 17 – Jul 17 | +6.58% | 15 of 15 | +0.91% |
| Jan 3 – Feb 2 | +4.24% | 14 of 15 | −12.07% |
| May 7 – Jun 6 | +3.57% | 12 of 15 | −11.12% |
| Oct 26 – Nov 15 | +3.42% | 12 of 15 | −5.71% |
| Dec 24 – Jan 23 | +3.37% | 12 of 15 | −11.28% |
GOOGL’s weak windows are less pronounced. The clearest is March 26 to April 5, which fell in 10 of 15 years and averaged −1.50%. Unlike many stocks, GOOGL’s September is nearly flat, at −0.31%, with a positive median of +1.04%.
