WeakGraded against IBB's own history at this drawdown — not the market's.
What it means: IBB's own history does not strongly favor buying at this level yet.
What to do: Consider watching and waiting for a deeper dip or a higher grade.
The fund generally will invest at least 80% of its assets in the component securities of its underlying index and may invest up to 20% of its assets in certain futures, options and swap contracts, cash and cash equivalents. It is non-diversified.
Three plain-English paragraphs — current state, historical base rate, and interpretation — so you walk away with context, not a dashboard.
In plain terms: IBB is 3.4% below its highest-ever price. Dipsern checks every past time it was this far down and grades how the next 90 days usually went.
iShares Biotechnology ETF (IBB) sits 3.4% off its peak and is currently in a shallow pullback, last printing at $171.44. Shallow pullbacks like this are routine — historically ETFs 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 IBB — 1025 confirmed observations in the 5%-to-0% 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 etfs return distributions. The win rate (% of episodes that closed positive after 90 days) is shown in the segments table below.
For broad-index ETFs the historical base rate is exceptionally stable; for narrow thematic ETFs (e.g., ARKK, cannabis, leveraged), drawdowns are deeper and the sample size at each band is smaller. 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.
