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.

Historically, May: over the last 12 years, SEDG gained +17.9% on average that month and finished up 67% of the time (12 years observed). June is the weakest month (-5.1%). This is not a prediction: 12 years is a small sample, and the past is under no obligation to repeat.
Why does SolarEdge stock often rise in May?
May has averaged as its best month over 12 years (+17.9%, up 67% of years). No clearly established recurring seasonal driver explains this month — it's a statistical tendency over 12 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 SEDG it's May (+17.9% on average over 12 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 SEDG, February is the most consistent month (73% positive years). We also rank all 12 months for the whole market.
Does stock seasonality actually work?
Careful. A month that rose 12 times out of 12 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 SEDG's real monthly closing prices from 2015 to 2026 (12 years), source Yahoo Finance. Each cell = the price change over that month. Price performance, excluding dividends. Incomplete months and quote gaps are excluded.
