Over 2013-2026, November is AutoZone's strongest month: +5.3% on average, positive in 12 of 13 years. At the other end, May shows -2.4%. 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 AutoZone's quarterly earnings move the stock?
November — when AutoZone reports quarterly earnings — has been its best month over 14 years (+5.3% on average, up 92% 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 AutoZone stock often rise in November?

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 AZO it's November (+5.3% 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 AZO, November is the most consistent month (92% 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.
What data is this table based on?
On AZO's real monthly closing prices from 2013 to 2026 (14 years), source Yahoo Finance. Each cell = the price change over that month. Price performance, excluding dividends. Incomplete months and quote gaps are excluded.
