Month by month
The stock's clearest edge over the S&P 500 lands in August (+8.3 pts); it has trailed the market most in October (−4.2 pts).
“vs S&P” is Varonis Systems’s average for a month minus the S&P 500’s average for that same month — isolating Varonis Systems’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, August has closed higher 100% of the time versus 90% across the last 10 years — the pattern is holding.
Figures are the typical (median) August return and how often it rose — the last 5 years versus the last 10(the heatmap’s default window). This verdict stays anchored to that 10-year window even if you zoom the chart, so it never disagrees with the badges above.
In plain English
Dependability is the through-line here. August stands out, higher in 9 of 10 Augusts, but it heads a clutch of months that pull the year reliably upward.
Its average (+8.6%) and median (+7.8%) land within a hair of each other — the tell of steady, year-after-year gains rather than one outlier doing the work. It is among its calmest months, too, its returns swinging least from year to year (a 8.2% spread), and even its worst August in 10 years lost only 5.9% — the gentlest downside anywhere on its calendar. Crucially, the gain is the stock's own rather than a rising tide's: August has cleared the S&P 500 by +8.3 points above the index. That consistency sets it apart from the field, where the average stock manages August only about 52% of the time.
The strength clusters rather than stands alone — April–August forms a firm stretch that carries much of the year. On the other side of the ledger, October has been the soft spot — the weakest of 3 months that average a loss (−3.1%), and the edge isn't year-round — the stock has trailed the S&P 500 in October, March, and September. Its roughest month on record was a −39.1% October in 2025 — a reminder of how hard even a seasonal name can fall.
August has now closed higher 6 years running. Reassuringly, the tendency has held its shape: the recent five years still track the years behind them.
The takeaway is less about when to buy than what to expect: August aside, the stock's months offer little reliable tilt.
Short answers on the stock's best month (August), its worst (October), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2016 its best month (August, +8.6%) has run well ahead of its worst (October, −3.1%) — the heatmap above shows how steady that gap has been year to year.
August has been the strongest, averaging +8.6% and closing higher in 9 of 10 years since 2016.
It's the weakest, averaging −3.1% — historically a soft spot, though it still varies from year to year.
