Does Amazon really go up in July?
Over 2013-2026, July is Amazon's strongest month: +7.0% on average, positive in 10 of 14 years. At the other end, September shows -1.7%. 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.

What is the best month to buy Amazon stock?
Historically, July: over the last 14 years, AMZN gained +7.0% on average that month and finished up 71% of the time (14 years observed). September is the weakest month (-1.7%). This is not a prediction: 14 years is a small sample, and the past is under no obligation to repeat.
Is it better to buy Amazon stock before Prime Day?
Historically, over 14 years, July is Amazon's best month (+7.0% on average, up 71% of years). July is Prime Day month, one of Amazon's biggest sales events. ⚠️ This is a past tendency over a short history, not a rule — Prime Day is already known and priced in by the market. Use it as context, never as a buy plan.
Why is Amazon stock weaker in September?
September has averaged as its weakest month over 14 years (-1.7%, up only 23% of years). September is a pre-season lull for a retailer, ahead of the Q4 holiday ramp-up.
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 AMZN it's July (+7.0% 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 AMZN, November is the most consistent month (77% 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 AMZN'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.
