Questions about COHR
What people ask.
Why is COHR on Broken Stocks?
COHR qualifies for the Red List on decline depth. It is down -31.0% from its rolling 252-day high of $440.00, set on 2026-06-03 — 98d ago.
Is COHR a falling knife?
By the most common technical definition — a steep, recent breakdown from a fresh high — yes. COHR is down -31.0% from its 52-week high of $440.00, set 98d ago. That combination of depth (past the 30% Amber threshold) and recency (high set inside the last 120 days) is the textbook falling-knife pattern. Whether to try to catch it is a separate question — historically most attempts to bottom-pick continue lower before reversing. Broken Stocks flags the pattern; it does not recommend buying or selling.
Is COHR 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 COHR trading inside its 52-week range?
At $303.48, COHR sits 61.6% of the way from its 52-week low ($84.35) to its 52-week high ($440.00). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
How fast has COHR been declining?
The current 31.0% decline accrued over 98d, which annualizes to roughly -115.5% 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 COHR compare to its sector?
There are 453 other Technology tickers on Broken Stocks: 293 Red, 95 Amber, 65 Watch, with 52 showing recovering structural signals. Median sector decline is -39.7% — COHR's decline is shallower than the sector median.
Does COHR'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 (2026-08-12) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
