Questions about AA
What people ask.
Why is AA on Broken Stocks?
AA qualifies for the Red List on decline depth. It is down -44.2% from its rolling 252-day high of $84.22, set on 2026-06-02 — 108d ago.
Is AA a falling knife?
By the most common technical definition — a steep, recent breakdown from a fresh high — yes. AA is down -44.2% from its 52-week high of $84.22, set 108d 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 — the classification does not predict subsequent returns. Broken Stocks flags the pattern; it does not recommend buying or selling.
Is AA 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 AA trading inside its 52-week range?
At $44.43, AA sits 25.6% of the way from its 52-week low ($30.71) to its 52-week high ($84.38). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
How fast has AA been declining?
The current 44.2% decline accrued over 108d, which annualizes to roughly -149.4% 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 AA compare to its sector?
There are 230 other Basic Materials tickers on Broken Stocks: 128 Red, 61 Amber, 41 Watch, with 101 showing recovering structural signals. Median sector decline is -36.2% — AA's decline is deeper than the sector median.
Does AA's earnings date affect its tier?
No. Tiering uses decline depth and recency, bearish time-frame structure, and decline sigma. The earnings date on file (2026-07-16) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
