WeakGraded against PPA's own history at this drawdown — not the market's.
What it means: PPA'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 90% of its total assets in securities that comprise the underlying index. The underlying index is composed of common stocks of companies that are systematically important to the defense sector and are involved with the development, manufacture, operation and support of U.S. defense, military, national/homeland security, and government space operations. The fund 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: PPA is 0.8% below its highest-ever price. Dipsern checks every past time it was this far down and grades how the next 90 days usually went.
Invesco Aerospace & Defense ETF (PPA) sits 0.8% off its peak and is currently at or near all-time highs, last printing at $184.07. That puts PPA in a momentum regime: buyers are in control and there's no meaningful technical damage on the chart yet.
History at this drawdown level is well-populated for PPA — 2857 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. At this level the Dipsern signal is mostly tracking momentum, not mean reversion. Most buying-the-dip frameworks aren't relevant when there is no dip.
