Three plain-English paragraphs — current state, historical base rate, and interpretation — so you walk away with context, not a dashboard.
In plain terms: COST is 9.8% below its highest-ever price. Dipsern checks every past time it was this far down and grades how the next 90 days usually went.
Costco (COST) sits 9.8% off its peak and is currently in a shallow pullback, last printing at $986.68. Shallow pullbacks like this are routine — historically US Stocks assets revisit a 5-10% dip several times a year, and most resolve back to highs within weeks.
History at this drawdown level is well-populated for COST — 1704 confirmed observations in the 10%-to-5% band. The Dipsern engine uses these to compute a rolling median rather than a mean, because medians are robust to the kind of fat tails you find in us stocks return distributions. The win rate (% of episodes that closed positive after 90 days) is shown in the segments table below.
S&P 500 names behave differently from small-caps at the same drawdown level — the Dipsern segmentation is per-ticker, so historical base rates for COST reflect its own volatility regime, not the market's. Shallow pullbacks are where dip-buying frameworks start to pay off, but only marginally. The median forward return in shallow bands is usually positive but not dramatic.
