Month by month
The stock's clearest edge over the S&P 500 lands in July (+9.7 pts); it has trailed the market most in April (−13.7 pts).
“vs S&P” is Seadrill Limited’s average for a month minus the S&P 500’s average for that same month — isolating Seadrill Limited’s own seasonal edge from broad market drift.
Reality check
Over the last 3 years, July has closed higher 100% of the time versus 100% across the last 4 years — the pattern is holding.
Figures are the typical (median) July return and how often it rose — the last 3 years versus the last 4(the heatmap’s default window). This verdict stays anchored to that 4-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. July stands out, higher in all 3 Julys, but it heads a clutch of months that pull the year reliably upward.
Its average (+11.9%) and median (+9.4%) 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 5.3% spread), and even its worst July in 4 years lost only 7.0% — the gentlest downside anywhere on its calendar. Crucially, the gain is the stock's own rather than a rising tide's: July has cleared the S&P 500 by +9.7 points above the index. That consistency sets it apart from the field, where the average stock manages July only about 61% of the time.
The strength clusters rather than stands alone — May–August forms a firm stretch that carries much of the year. The weaker half of the year is plainer: February has been the soft spot — the weakest of 3 months that average a loss (−12.5%), and the edge isn't year-round — the stock has trailed the S&P 500 in April, February, and September. Its roughest month on record was a −27.5% February in 2025 — a reminder of how hard even a seasonal name can fall.
The takeaway is less about when to buy than what to expect: July aside, the stock's months offer little reliable tilt. With a short 4-year record, the signal is best held loosely.
Short answers on the stock's best month (July), its worst (February), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2022 its best month (July, +11.9%) has run well ahead of its worst (February, −12.5%) — the heatmap above shows how steady that gap has been year to year.
July has been the strongest, averaging +11.9% and closing higher in all 3 years on record since 2022.
It's the weakest, averaging −12.5% — historically a soft spot, though it still varies from year to year.
