Month by month
The stock's clearest edge over the S&P 500 lands in December (+2.0 pts); it has trailed the market most in August (−6.5 pts).
“vs S&P” is Dentsply Sirona Inc’s average for a month minus the S&P 500’s average for that same month — isolating Dentsply Sirona Inc’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, December has closed higher 80% of the time versus 60% across the last 10 years — the pattern is strengthening.
Figures are the typical (median) December 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
This is a feast-or-famine calendar. December reads as the strong month, higher in 6 of 10 Decembers, but the tale is one of a few outsized years more than steady gains.
Read it with one caveat: the average (+3.0%) runs well ahead of the median (+1.1%), so a handful of outsized years — not steady strength — do much of the lifting. Few months are steadier: December's returns vary by just 5.4% year to year, and even its worst December in 10 years lost only 3.4% — the gentlest downside anywhere on its calendar. Better still, that strength is the stock's own and not just a buoyant market — December has outpaced the S&P 500 by +2.0 points on average.
Only April comes anywhere near it for reliability. On the other side of the ledger, August has been the soft spot — the weakest of 7 months that average a loss (−6.2%), and the edge isn't year-round — the stock has trailed the S&P 500 in August, March, and November. Its roughest month on record was a −21.6% March in 2020 — a reminder of how hard even a seasonal name can fall.
If anything it has sharpened recently — the last five Decembers run ahead of the earlier years.
Hold it loosely, then: the December tendency is genuine but lumpy, more about the occasional outsized year than a gain to bank on.
Short answers on the stock's best month (December), its worst (August), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2016 its best month (December, +3.0%) has run well ahead of its worst (August, −6.2%) — the heatmap above shows how steady that gap has been year to year.
December has been the strongest, averaging +3.0% and closing higher in 6 of 10 years since 2016.
It's the weakest, averaging −6.2% — historically a soft spot, though it still varies from year to year.
