Month by month
The stock's clearest edge over the S&P 500 lands in June (+5.9 pts); it has trailed the market most in September (−4.8 pts).
“vs S&P” is Bentley Systems Inc’s average for a month minus the S&P 500’s average for that same month — isolating Bentley Systems Inc’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, March has closed higher 80% of the time versus 80% across the last 6 years — the pattern is holding.
Figures are the typical (median) March return and how often it rose — the last 5 years versus the last 6(the heatmap’s default window). This verdict stays anchored to that 6-year window even if you zoom the chart, so it never disagrees with the badges above.
In plain English
The seasonal story is really one month's story — March. It has closed higher in 4 of 5 Marches, a concentration the rest of the calendar can't touch.
The strength looks broad-based rather than freakish: its average (+4.4%) and median (+5.5%) sit close together, so no single blow-out year is flattering the figure. Better still, that strength is the stock's own and not just a buoyant market — March has outpaced the S&P 500 by +3.4 points on average. Few peers keep such company in March — the typical stock clears it just 56% of the time.
March anchors a run, too: the March-through-July window has been the stock's reliable season. On the other side of the ledger, September has been the soft spot — the weakest of 5 months that average a loss (−5.0%), and the edge isn't year-round — the stock has trailed the S&P 500 in September, November, and January. Its roughest month on record was a −18.0% November in 2021 — a reminder of how hard even a seasonal name can fall.
For a stock this dependable in March, the sharper question is the rest of the year — outside its strong stretch, the calendar gives far less to lean on. With a short 6-year record, the signal is best held loosely.
Short answers on the stock's best month (March), its worst (September), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2020 its best month (March, +4.4%) has run well ahead of its worst (September, −5.0%) — the heatmap above shows how steady that gap has been year to year.
March has been the strongest, averaging +4.4% and closing higher in 4 of 5 years since 2020.
It's the weakest, averaging −5.0% — historically a soft spot, though it still varies from year to year.
