Questions about ATEC
What people ask.
Why is ATEC on Broken Stocks?
ATEC qualifies for the Red List on decline depth. It is down -60.1% from its rolling 252-day high of $23.29, set on 2026-01-08 — 224d ago.
Is ATEC a falling knife?
Not by the strict technical definition. ATEC is down -60.1% from its 52-week high, but that high was set 224d ago — more than 120 days. A falling knife is usually a recent breakdown from a fresh high, not an established multi-quarter downtrend. ATEC is still on the Red List for decline depth, but the freshness component of a falling knife is missing.
Is ATEC 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 ATEC trading inside its 52-week range?
At $9.29, ATEC sits 15.0% of the way from its 52-week low ($6.82) to its 52-week high ($23.29). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
How fast has ATEC been declining?
The current 60.1% decline accrued over 224d, which annualizes to roughly -97.9% 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 ATEC compare to its sector?
There are 143 other Healthcare tickers on Broken Stocks: 69 Red, 35 Amber, 39 Watch, with 50 showing recovering structural signals. Median sector decline is -36.1% — ATEC's decline is deeper than the sector median.
Does ATEC'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 (2026-08-04) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
