Month by month
The stock's clearest edge over the S&P 500 lands in May (+4.8 pts); it has trailed the market most in March (−3.4 pts).
“vs S&P” is BlackRock Science and Technology Trust II’s average for a month minus the S&P 500’s average for that same month — isolating BlackRock Science and Technology Trust II’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, June has closed higher 80% of the time versus 86% across the last 7 years — the pattern is holding.
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
Strip the year back and a single month does the heavy lifting: June, up in 6 of 7 Junes while the other eleven tend to blur together.
Its average (+2.9%) and median (+3.8%) land within a hair of each other — the tell of steady, year-after-year gains rather than one outlier doing the work. Crucially, the gain is the stock's own rather than a rising tide's: June has cleared the S&P 500 by +2.7 points above the index. That consistency sets it apart from the field, where the average stock manages June only about 52% of the time.
A few other months pull their weight: January and May have also closed higher more often than not. At the other end of the calendar, February has been the soft spot — the weakest of 5 months that average a loss (−3.2%), and the edge isn't year-round — the stock has trailed the S&P 500 in March, September, and April. Its roughest month on record was a −19.0% April in 2022 — a reminder of how hard even a seasonal name can fall.
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: June aside, the stock's months offer little reliable tilt. With a short 7-year record, the signal is best held loosely.
Short answers on the stock's best month (June), its worst (February), and whether it really trades seasonally.
Yes, to a moderate degree. Since 2019 its best month (June, +2.9%) has run well ahead of its worst (February, −3.2%) — the heatmap above shows how steady that gap has been year to year.
June has been the strongest, averaging +2.9% and closing higher in 6 of 7 years since 2019.
It's the weakest, averaging −3.2% — historically a soft spot, though it still varies from year to year.
