Month by month
The fund's clearest edge over the S&P 500 lands in April (+5.4 pts); it has trailed the market most in March (−5.2 pts).
“vs S&P” is Global X MLP ETF’s average for a month minus the S&P 500’s average for that same month — isolating Global X MLP ETF’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, May has closed higher 100% of the time versus 80% across the last 10 years — the pattern is strengthening.
Figures are the typical (median) May 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
The seasonal story is really one month's story — May. It has closed higher in 8 of 10 Mays, a concentration the rest of the calendar can't touch.
The strength looks broad-based rather than freakish: its average (+3.4%) and median (+2.6%) sit close together, so no single blow-out year is flattering the figure. Few months are steadier: May's returns vary by just 4.5% year to year, and even its worst May in 10 years lost only 3.4% — the gentlest downside anywhere on its calendar. Better still, that strength is the fund's own and not just a buoyant market — May has outpaced the S&P 500 by +2.6 points on average. Few peers keep such company in May — the typical stock clears it just 55% of the time.
May anchors a run, too: the May-through-July window has been the fund's reliable season. At the other end of the calendar, October has been the soft spot — the weakest of 5 months that average a loss (−0.8%), and the edge isn't year-round — the fund has trailed the S&P 500 in March, October, and September. Its roughest month on record was a −49.6% March in 2020 — a reminder of how hard even a seasonal name can fall.
May has now closed higher 6 years running. If anything it has sharpened recently — the last five Mays run ahead of the earlier years.
For a fund this dependable in May, the sharper question is the rest of the year — outside its strong stretch, the calendar gives far less to lean on.
Short answers on the fund's best month (May), its worst (October), and whether it really trades seasonally.
Yes, to a moderate degree. Since 2016 its best month (May, +3.4%) has run well ahead of its worst (October, −0.8%) — the heatmap above shows how steady that gap has been year to year.
May has been the strongest, averaging +3.4% and closing higher in 8 of 10 years since 2016.
It's the weakest, averaging −0.8% — historically a soft spot, though it still varies from year to year.
