Questions about ADTN
What people ask.
Why is ADTN on Broken Stocks?
ADTN qualifies for the Red List on decline depth. It is down -47.7% from its rolling 252-day high of $19.98, set on 2026-05-27 — 56d ago.
Is ADTN a falling knife?
By the most common technical definition — a steep, recent breakdown from a fresh high — yes. ADTN is down -47.7% from its 52-week high of $19.98, set 56d 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 ADTN 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 ADTN trading inside its 52-week range?
At $10.45, ADTN sits 26.0% of the way from its 52-week low ($7.11) to its 52-week high ($19.98). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
How fast has ADTN been declining?
The current 47.7% decline accrued over 56d, which annualizes to roughly -310.9% 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 ADTN compare to its sector?
There are 237 other Technology tickers on Broken Stocks: 152 Red, 49 Amber, 36 Watch, with 35 showing recovering structural signals. Median sector decline is -40.7% — ADTN's decline is deeper than the sector median.
Does ADTN'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 (2026-05-04) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
