WeakGraded against IUSB's own history at this drawdown — not the market's.
What it means: IUSB'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 will invest at least 80% of its assets in the component securities of the underlying index and to-be-announced transactions (“TBAs”) that have economic characteristics that are substantially identical to the economic characteristics of the component securities of the underlying index. The index measures the performance of U.S. dollar-denominated taxable bonds that are rated either investment-grade or high yield.
Three plain-English paragraphs — current state, historical base rate, and interpretation — so you walk away with context, not a dashboard.
In plain terms: IUSB is 2.7% below its highest-ever price. Dipsern checks every past time it was this far down and grades how the next 90 days usually went.
IUSB (iShares Core Total USD Bond Market ETF) is 2.7% below its historical peak. Tape reads in a shallow pullback, with the last trade at $45.45. 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.
IUSB reaches this drawdown band repeatedly in its history (2227 observations), which is a large sample for the segmentation engine to compute a stable median forward return. The engine uses a rolling 90-day window and gives more weight to recent years — this lets the signal adapt to regime changes (e.g., post-COVID volatility) without losing the long-run base rate.
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.
