Questions about ADPT
What people ask.
Why is ADPT on Broken Stocks?
ADPT qualifies for the Amber List on decline depth. It is down -36.5% from its rolling 252-day high of $20.76, set on 2025-11-25 — 170d ago.
Is ADPT a falling knife?
Not by the strict technical definition. ADPT is down -36.5% from its 52-week high, but that high was set 170d ago — more than 120 days. A falling knife is usually a recent breakdown from a fresh high, not an established multi-quarter downtrend. ADPT is still on the Amber List for decline depth, but the freshness component of a falling knife is missing.
Is ADPT a buy?
Broken Stocks does not issue buy or sell recommendations. The list is a rules-based technical warning system. It tracks structural decline depth and recency — not company quality, management, fundamentals, or news. Always do your own research and consult a licensed advisor.
Where is ADPT trading inside its 52-week range?
At $13.18, ADPT sits 38.8% of the way from its 52-week low ($8.38) to its 52-week high ($20.76). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
How fast has ADPT been declining?
The current 36.5% decline accrued over 170d, which annualizes to roughly -78.4% per year. Annualized pace is a sanity check — a 30% decline in three months is a different signal than a 30% decline over two years.
How does ADPT compare to its sector?
There are 182 other Healthcare tickers on Broken Stocks: 93 Red, 42 Amber, 47 Watch, with 55 showing recovering structural signals. Median sector decline is -35.8% — ADPT's decline is deeper than the sector median.
Does ADPT's earnings date affect its tier?
No. Tiering is decided purely by decline depth and recency of the rolling-high date. The earnings date on file (2026-05-05) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
