Questions about AAOI

What people ask.

Why is AAOI on Broken Stocks?

AAOI qualifies for the Red List on decline depth. It is down -40.5% from its rolling 252-day high of $233.67, set on 2026-05-13 — 49d ago.

Is AAOI a falling knife?

By the most common technical definition — a steep, recent breakdown from a fresh high — yes. AAOI is down -40.5% from its 52-week high of $233.67, set 49d 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 AAOI 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 AAOI trading inside its 52-week range?

At $139.00, AAOI sits 56.6% of the way from its 52-week low ($15.29) to its 52-week high ($233.67). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.

How fast has AAOI been declining?

The current 40.5% decline accrued over 49d, which annualizes to roughly -301.7% 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 AAOI compare to its sector?

There are 194 other Technology tickers on Broken Stocks: 123 Red, 45 Amber, 26 Watch, with 83 showing recovering structural signals. Median sector decline is -41.1% — AAOI's decline is shallower than the sector median.

Does AAOI'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.
