Questions about CNM
What people ask.
Why is CNM on Broken Stocks?
CNM qualifies for the Amber List on decline depth. It is down -31.9% from its rolling 252-day high of $59.66, set on 2026-02-12 — 213d ago.
Is CNM a falling knife?
Not by the strict technical definition. CNM is down -31.9% from its 52-week high, but that high was set 213d ago — more than 120 days. A falling knife is usually a recent breakdown from a fresh high, not an established multi-quarter downtrend. CNM is still on the Amber List for decline depth, but the freshness component of a falling knife is missing.
Is CNM 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 CNM trading inside its 52-week range?
At $40.62, CNM sits 0.0% of the way from its 52-week low ($41.55) to its 52-week high ($59.66). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
How fast has CNM been declining?
The current 31.9% decline accrued over 213d, which annualizes to roughly -54.7% 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 CNM compare to its sector?
There are 341 other Industrials tickers on Broken Stocks: 193 Red, 85 Amber, 63 Watch, with 33 showing recovering structural signals. Median sector decline is -36.3% — CNM's decline is shallower than the sector median.
Does CNM'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 (2026-09-09) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
