Questions about ANNX

What people ask.

Why is ANNX on Broken Stocks?

ANNX qualifies for the Red List on decline depth. It is down -25.2% from its rolling 252-day high of $7.18, set on 2026-01-23 — 111d ago.

Is ANNX a falling knife?

No. The falling-knife label usually implies a steep, severe drop — typically 30% or more from a fresh high. ANNX is down -25.2% from its 52-week high, which qualifies for the Watch tier but is shallower than the falling-knife pattern. It's an early-stage decline rather than a sharp breakdown.

Is ANNX 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 ANNX trading inside its 52-week range?

At $5.37, ANNX sits 67.2% of the way from its 52-week low ($1.67) to its 52-week high ($7.18). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.

How fast has ANNX been declining?

The current 25.2% decline accrued over 111d, which annualizes to roughly -82.9% 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 ANNX compare to its sector?

There are 182 other Healthcare tickers on Broken Stocks: 92 Red, 43 Amber, 47 Watch, with 55 showing recovering structural signals. Median sector decline is -35.8% — ANNX's decline is shallower than the sector median.

Does ANNX'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 (2026-05-07) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
