The structural read
What price action says about ALNY.
ALNY qualifies for the Red List on decline depth — down -53.7% from its rolling 252-day high. Past the 40% threshold, the deepest tier in the taxonomy.
Cross-confirmation: also showing 3/5 bearish time frames.
Alongside that decline, our proprietary engine has flagged a confirmed bullish structural signal on one or more time frames — moderate or strong time-frame-continuity (TFC) alignment — so the ticker also carries a Recovering badge. The two readings coexist: the tier tells you how deep the damage is, the Recovering badge tells you whether momentum may be turning. Recovering is not a buy signal; it's a structural read.
Broken Stocks stops here — it flags the structure, it doesn't build the upside case. Working out whether ALNY's turn is investable is what our sister tool does: ConvictionEdge — triple-engine conviction research on names showing a recovery signal.
Upstream TFC read: moderate alignment, current phase weekly. Last bar types — daily 2D (red), weekly 2U (green), monthly 1 (green).

Questions about ALNY
What people ask.
Why is ALNY on Broken Stocks?
ALNY qualifies for the Red List on decline depth. It is down -53.7% from its rolling 252-day high of $495.55, set on 2025-10-20 — 304d ago. It additionally carries a Recovering badge — see below.
What does the Recovering badge mean for ALNY?
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 — ALNY is still Red 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 ALNY a falling knife?
Not by the strict technical definition. ALNY is down -53.7% from its 52-week high, but that high was set 304d ago — more than 120 days. A falling knife is usually a recent breakdown from a fresh high, not an established multi-quarter downtrend. ALNY is still on the Red List for decline depth, but the freshness component of a falling knife is missing.
Is ALNY 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 ALNY trading inside its 52-week range?
At $229.30, ALNY sits 10.6% of the way from its 52-week low ($197.81) to its 52-week high ($495.55). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
How fast has ALNY been declining?
The current 53.7% decline accrued over 304d, which annualizes to roughly -64.5% 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 ALNY compare to its sector?
There are 143 other Healthcare tickers on Broken Stocks: 69 Red, 35 Amber, 39 Watch, with 49 showing recovering structural signals. Median sector decline is -36.1% — ALNY's decline is deeper than the sector median.
Does ALNY'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 (2026-07-30) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
