The structural read
What price action says about ALC.
ALC qualifies for the Amber List on decline depth — down -30.5% from its rolling 252-day high.
Cross-confirmation: also showing 3/5 bearish time frames.
Cross-confirmation: decline sigma also reads 7.4σ over 20 bars.
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.
Upstream TFC read: moderate alignment, current phase daily. Last bar types — daily 2U (green), weekly 2D (green), monthly 2D (red).
Earnings on file: 2026-05-05. Tiering is unaffected by earnings dates — listings reflect price structure only.

Questions about ALC
What people ask.
Why is ALC on Broken Stocks?
ALC qualifies for the Amber List on decline depth. It is down -30.5% from its rolling 252-day high of $92.10, set on 2025-07-24 — 294d ago. It additionally carries a Recovering badge — see below.
What does the Recovering badge mean for ALC?
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 — ALC 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 ALC a falling knife?
Not by the strict technical definition. ALC is down -30.5% from its 52-week high, but that high was set 294d ago — more than 120 days. A falling knife is usually a recent breakdown from a fresh high, not an established multi-quarter downtrend. ALC is still on the Amber List for decline depth, but the freshness component of a falling knife is missing.
Is ALC 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 ALC trading inside its 52-week range?
At $64.00, ALC sits 7.0% of the way from its 52-week low ($61.84) to its 52-week high ($92.55). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
How fast has ALC been declining?
The current 30.5% decline accrued over 294d, which annualizes to roughly -37.9% 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 ALC compare to its sector?
There are 182 other Healthcare tickers on Broken Stocks: 93 Red, 42 Amber, 47 Watch, with 54 showing recovering structural signals. Median sector decline is -35.8% — ALC's decline is shallower than the sector median.
Does ALC'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.
