“vs S&P” is Portfolio Building Block Integrated Oil and Gas and Exploration and Production Index ETF’s average for a month minus the S&P 500’s average for that same month — isolating Portfolio Building Block Integrated Oil and Gas and Exploration and Production Index ETF’s own seasonal edge from broad market drift.
Reality check
Not enough recent November history to say whether the pattern still holds.
Figures are the typical (median) November return and how often it rose — the last 1 years versus the last 1(the heatmap’s default window). This verdict stays anchored to that 1-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 — November. It has closed higher in all 1 Novembers, a concentration the rest of the calendar can't touch.
The strength looks broad-based rather than freakish: its average (+1.4%) and median (+1.4%) sit close together, so no single blow-out year is flattering the figure. No month is steadier: November's returns vary by just 0.0% year to year, and even its worst November in 1 years lost only 1.4% — the gentlest downside anywhere on its calendar. Few peers keep such company in November — the typical stock clears it just 62% of the time.
No other month comes close to matching it — the rest of the calendar is unremarkable by comparison. The weaker half of the year is plainer: December has been the soft spot — the only month to average an outright loss (−0.8%), and the edge isn't year-round — the fund has trailed the S&P 500 in December and November.
For a fund this dependable in November, the sharper question is the rest of the year — outside its strong stretch, the calendar gives far less to lean on. With a short 1-year record, the signal is best held loosely.
Short answers on the fund's best month (November), its worst (December), and whether it really trades seasonally.
Only mildly. The fund's months are fairly even — November is the firmest (+1.4%) and December the softest (−0.8%), a narrow spread that points to weak seasonality rather than a strong calendar effect.
November has been the strongest, averaging +1.4% and closing higher in its one year on record since 2025.
It's the weakest, averaging −0.8% — historically a soft spot, though it still varies from year to year.
