Questions about AMTM

What people ask.

Why is AMTM on Broken Stocks?

AMTM qualifies for the Red List on decline depth. It is down -39.0% from its rolling 252-day high of $38.11, set on 2026-02-06 — 97d ago.

Is AMTM a falling knife?

By the most common technical definition — a steep, recent breakdown from a fresh high — yes. AMTM is down -39.0% from its 52-week high of $38.11, set 97d 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 AMTM 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 AMTM trading inside its 52-week range?

At $23.25, AMTM sits 21.8% of the way from its 52-week low ($19.11) to its 52-week high ($38.11). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.

How fast has AMTM been declining?

The current 39.0% decline accrued over 97d, which annualizes to roughly -146.8% 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 AMTM compare to its sector?

There are 119 other Industrials tickers on Broken Stocks: 60 Red, 22 Amber, 37 Watch, with 23 showing recovering structural signals. Median sector decline is -32.5% — AMTM's decline is deeper than the sector median.

Does AMTM'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 (2026-05-11) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
