Questions about AMPH
What people ask.
Why is AMPH on Broken Stocks?
AMPH qualifies for the Amber List on decline depth. It is down -21.9% from its rolling 252-day high of $29.52, set on 2026-01-12 — 240d ago. It additionally carries a Recovering badge — see below.
What does the Recovering badge mean for AMPH?
Recovering means our proprietary engine has flagged a confirmed bullish structural signal on one or more time frames (moderate or strong time-frame continuity). It coexists with the decline tier — AMPH is still Amber List because the rolling-252-day decline hasn't healed, but a bullish setup has formed inside that decline. The two readings answer different questions: the tier tells you how deep the damage is; the Recovering badge tells you whether momentum may be turning. It's not a buy recommendation.
Is AMPH a falling knife?
No. The falling-knife label usually implies a steep, severe drop — typically 30% or more from a fresh high. AMPH is down -21.9% from its 52-week high, which qualifies for the Watch tier but is shallower than the falling-knife pattern. It's an early-stage decline rather than a sharp breakdown.
Is AMPH 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 AMPH trading inside its 52-week range?
At $23.04, AMPH sits 43.7% of the way from its 52-week low ($16.65) to its 52-week high ($31.26). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
How fast has AMPH been declining?
The current 21.9% decline accrued over 240d, which annualizes to roughly -33.3% 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 AMPH compare to its sector?
There are 276 other Healthcare tickers on Broken Stocks: 135 Red, 80 Amber, 61 Watch, with 33 showing recovering structural signals. Median sector decline is -35.2% — AMPH's decline is shallower than the sector median.
Does AMPH'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 (2026-08-06) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
