Questions about ATRC
What people ask.
Why is ATRC on Broken Stocks?
ATRC qualifies for the Amber List on decline depth. It is down -35.0% from its rolling 252-day high of $43.18, set on 2026-01-08 — 140d ago.
Is ATRC a falling knife?
Not by the strict technical definition. ATRC is down -35.0% from its 52-week high, but that high was set 140d ago — more than 120 days. A falling knife is usually a recent breakdown from a fresh high, not an established multi-quarter downtrend. ATRC is still on the Amber List for decline depth, but the freshness component of a falling knife is missing.
Is ATRC 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 ATRC trading inside its 52-week range?
At $28.09, ATRC sits 14.6% of the way from its 52-week low ($25.52) to its 52-week high ($43.18). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
How fast has ATRC been declining?
The current 35.0% decline accrued over 140d, which annualizes to roughly -91.2% 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 ATRC compare to its sector?
There are 194 other Healthcare tickers on Broken Stocks: 89 Red, 46 Amber, 59 Watch, with 108 showing recovering structural signals. Median sector decline is -36.0% — ATRC's decline is shallower than the sector median.
Does ATRC'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.
