Questions about ACM
What people ask.
Why is ACM on Broken Stocks?
ACM qualifies for the Red List on decline depth. It is down -55.8% from its rolling 252-day high of $133.31, set on 2025-11-13 — 337d ago. It additionally carries a Recovering badge — see below.
What does the Recovering badge mean for ACM?
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 — ACM is still Red List because a price-structure rule still triggers, but a bullish setup has formed inside that decline. The two readings answer different questions: the tier reflects the most severe triggered rule; the Recovering badge tells you whether momentum may be turning. It's not a buy recommendation.
Is ACM a falling knife?
Not by the strict technical definition. ACM is down -55.8% from its 52-week high, but that high was set 337d ago — more than 120 days. A falling knife is usually a recent breakdown from a fresh high, not an established multi-quarter downtrend. ACM is still on the Red List for decline depth, but the freshness component of a falling knife is missing.
Is ACM 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 ACM trading inside its 52-week range?
At $58.94, ACM sits 0.0% of the way from its 52-week low ($60.35) to its 52-week high ($135.52). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
How fast has ACM been declining?
The current 55.8% decline accrued over 337d, which annualizes to roughly -60.4% 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 ACM compare to its sector?
There are 628 other Industrials tickers on Broken Stocks: 396 Red, 148 Amber, 84 Watch, with 291 showing recovering structural signals. Median sector decline is -35.7% — ACM's decline is deeper than the sector median.
Does ACM's earnings date affect its tier?
No. Tiering uses decline depth and recency, bearish time-frame structure, and decline sigma. The earnings date on file (2026-08-10) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
