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 Flowserve stock?

Historically, October: over the last 14 years, FLS gained +3.4% on average that month and finished up 62% of the time (13 years observed). March is the weakest month (-2.4%). This is not a prediction: 14 years is a small sample, and the past is under no obligation to repeat.

Why does Flowserve stock often rise in October?

October has averaged as its best month over 14 years (+3.4%, up 62% of years). No clearly established recurring seasonal driver explains this month — it's a statistical tendency over 14 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 FLS it's October (+3.4% 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 FLS, February is the most consistent month (64% 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 FLS'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.
