Month by month
The stock's clearest edge over the S&P 500 lands in December (+9.8 pts); it has trailed the market most in March (−9.8 pts).
“vs S&P” is Roivant Sciences Ltd’s average for a month minus the S&P 500’s average for that same month — isolating Roivant Sciences Ltd’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, July has closed higher 80% of the time versus 80% across the last 6 years — the pattern is holding.
Figures are the typical (median) July 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
This is a stock you can almost set a calendar by, and July is the anchor — it has closed higher in 4 of 5 Julys, the steadiest beat on its year.
Read it with one caveat: the average (+3.4%) runs well ahead of the median (+0.2%), so a handful of outsized years — not steady strength — do much of the lifting. That reliability comes with real swings, mind — even July ranges by 10.7% from year to year, so any single year can land far from the average. Better still, that strength is the stock's own and not just a buoyant market — July has outpaced the S&P 500 by +1.3 points on average. Few peers keep such company in July — the typical stock clears it just 61% of the time.
July anchors a run, too: the June-through-August window has been the stock's reliable season. At the other end of the calendar, March has been the soft spot — the weakest of 3 months that average a loss (−8.8%), and the edge isn't year-round — the stock has trailed the S&P 500 in March, January, and November. Its roughest month on record was a −29.9% January in 2022 — a reminder of how hard even a seasonal name can fall.
For a stock this dependable in July, 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.
