Month by month
The stock's clearest edge over the S&P 500 lands in January (+8.5 pts); it has trailed the market most in March (−7.9 pts).
“vs S&P” is Hess Midstream Partners LP’s average for a month minus the S&P 500’s average for that same month — isolating Hess Midstream Partners LP’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, January has closed higher 100% of the time versus 100% across the last 9 years — the pattern is holding.
Figures are the typical (median) January return and how often it rose — the last 5 years versus the last 9(the heatmap’s default window). This verdict stays anchored to that 9-year window even if you zoom the chart, so it never disagrees with the badges above.
In plain English
Strip the year back and a single month does the heavy lifting: January, up in all 8 Januaries while the other eleven tend to blur together.
Its average (+8.3%) and median (+6.4%) 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 6.1% spread), and even its worst January in 9 years lost only 4.0% — the gentlest downside anywhere on its calendar. Crucially, the gain is the stock's own rather than a rising tide's: January has cleared the S&P 500 by +8.5 points above the index. That consistency sets it apart from the field, where the average stock manages January only about 53% of the time.
A few other months pull their weight: May and July have also closed higher more often than not. At the other end of the calendar, September has been the soft spot — the weakest of 5 months that average a loss (−3.5%), and the edge isn't year-round — the stock has trailed the S&P 500 in March, September, and June. Its roughest month on record was a −48.5% March in 2020 — a reminder of how hard even a seasonal name can fall.
January has now closed higher 8 years running. Reassuringly, the tendency has held its shape: the recent five years still track the years behind them.
The takeaway is less about when to buy than what to expect: January aside, the stock's months offer little reliable tilt. With a short 9-year record, the signal is best held loosely.
Short answers on the stock's best month (January), its worst (September), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2017 its best month (January, +8.3%) has run well ahead of its worst (September, −3.5%) — the heatmap above shows how steady that gap has been year to year.
January has been the strongest, averaging +8.3% and closing higher in all 8 years on record since 2017.
It's the weakest, averaging −3.5% — historically a soft spot, though it still varies from year to year.
