Why does Roku, Inc. stock often rise in November?
November has averaged as its best month over 10 years (+22.0%, up 67% of years). No clearly established recurring seasonal driver explains this month — it's a statistical tendency over 10 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 ROKU it's November (+22.0% on average over 10 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 ROKU, June is the most consistent month (89% positive years). We also rank all 12 months for the whole market.
Does stock seasonality actually work?
Careful. A month that rose 10 times out of 10 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 ROKU's real monthly closing prices from 2017 to 2026 (10 years), source Yahoo Finance. Each cell = the price change over that month. Price performance, excluding dividends. Incomplete months and quote gaps are excluded.
