Month by month
The stock's clearest edge over the S&P 500 lands in January (+36.7 pts); it has trailed the market most in April (−13.4 pts).
“vs S&P” is Ehang Holdings Ltd’s average for a month minus the S&P 500’s average for that same month — isolating Ehang Holdings Ltd’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, June has closed higher 80% of the time versus 67% across the last 7 years — the pattern is strengthening.
Figures are the typical (median) June return and how often it rose — the last 5 years versus the last 7(the heatmap’s default window). This verdict stays anchored to that 7-year window even if you zoom the chart, so it never disagrees with the badges above.
In plain English
June looks the standout, up in 4 of 6 Junes — yet the appeal is lumpy, leaning on the occasional blow-out year rather than dependable strength.
The headline flatters a touch — its +12.1% average sits well above the +5.7% a typical year delivers, the work of a few big Junes. That reliability comes with real swings, mind — even June ranges by 26.0% from year to year, so any single year can land far from the average. Crucially, the gain is the stock's own rather than a rising tide's: June has cleared the S&P 500 by +11.8 points above the index. That consistency sets it apart from the field, where the average stock manages June only about 52% of the time.
At the other end of the calendar, April has been the soft spot — the weakest of 6 months that average a loss (−11.8%), and the edge isn't year-round — the stock has trailed the S&P 500 in April, July, and September. Its roughest month on record was a −43.2% February in 2021 — a reminder of how hard even a seasonal name can fall.
If anything it has sharpened recently — the last five Junes run ahead of the earlier years.
Hold it loosely, then: the June tendency is genuine but lumpy, more about the occasional outsized year than a gain to bank on. With a short 7-year record and returns that swing hard year to year, the signal is best held loosely.
Short answers on the stock's best month (June), its worst (April), and whether it really trades seasonally.
Yes, to a pronounced degree. Since 2019 its best month (June, +12.1%) has run well ahead of its worst (April, −11.8%) — the heatmap above shows how steady that gap has been year to year.
June has been the strongest, averaging +12.1% and closing higher in 4 of 6 years since 2019.
It's the weakest, averaging −11.8% — historically a soft spot, though it still varies from year to year.
