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.

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 SITM it's May (+22.6% on average over 8 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 SITM, November is the most consistent month (100% positive years). We also rank all 12 months for the whole market.
Does stock seasonality actually work?
Careful. A month that rose 8 times out of 8 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 SITM's real monthly closing prices from 2019 to 2026 (8 years), source Yahoo Finance. Each cell = the price change over that month. Price performance, excluding dividends. Incomplete months and quote gaps are excluded.
