Month by month
The stock's clearest edge over the S&P 500 lands in August (+1.0 pts); it has trailed the market most in March (−2.2 pts).
“vs S&P” is BlackRock Limited Duration Income Trust’s average for a month minus the S&P 500’s average for that same month — isolating BlackRock Limited Duration Income Trust’s own seasonal edge from broad market drift.
Reality check
Over the last 5 years, August has closed higher 100% of the time versus 100% across the last 10 years — the pattern is holding.
Figures are the typical (median) August 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
Dependability is the through-line here. August stands out, higher in all 10 Augusts, but it heads a clutch of months that pull the year reliably upward.
Its average (+1.4%) and median (+1.2%) land within a hair of each other — the tell of steady, year-after-year gains rather than one outlier doing the work. It is also the calendar's calmest month, its returns swinging least from year to year (a 0.7% spread), and even its worst August in 10 years lost only 0.4% — the gentlest downside anywhere on its calendar. Crucially, the gain is the stock's own rather than a rising tide's: August has cleared the S&P 500 by +1.0 points above the index. That consistency sets it apart from the field, where the average stock manages August only about 52% of the time.
The strength clusters rather than stands alone — April–August forms a firm stretch that carries much of the year. The weaker half of the year is plainer: March has been the soft spot — the weakest of 3 months that average a loss (−1.2%), and the edge isn't year-round — the stock has trailed the S&P 500 in March, October, and September. Its roughest month on record was a −17.4% March in 2020 — a reminder of how hard even a seasonal name can fall.
August has now closed higher 10 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: August aside, the stock's months offer little reliable tilt.
Short answers on the stock's best month (August), its worst (March), and whether it really trades seasonally.
Only mildly. The stock's months are fairly even — August is the firmest (+1.4%) and March the softest (−1.2%), a narrow spread that points to weak seasonality rather than a strong calendar effect.
August has been the strongest, averaging +1.4% and closing higher in all 10 years on record since 2016.
It's the weakest, averaging −1.2% — historically a soft spot, though it still varies from year to year.
