Historically, August: over the last 14 years, NMIH gained +6.2% on average that month and finished up 83% of the time (12 years observed). March is the weakest month (-4.5%). This is not a prediction: 14 years is a small sample, and the past is under no obligation to repeat.
Why does NMI Holdings, Inc. stock often rise in August?
August has averaged as its best month over 14 years (+6.2%, up 83% 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 NMIH it's August (+6.2% 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 NMIH, August is the most consistent month (83% 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 NMIH'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.
