Questions about ARM
What people ask.
Why is ARM on Broken Stocks?
ARM qualifies for the Red List on decline depth. It is down -41.6% from its rolling 252-day high of $452.70, set on 2026-06-18 — 83d ago.
Is ARM a falling knife?
By the most common technical definition — a steep, recent breakdown from a fresh high — yes. ARM is down -41.6% from its 52-week high of $452.70, set 83d 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 ARM 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 ARM trading inside its 52-week range?
At $264.23, ARM sits 46.6% of the way from its 52-week low ($100.02) to its 52-week high ($452.70). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
How fast has ARM been declining?
The current 41.6% decline accrued over 83d, which annualizes to roughly -182.9% 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 ARM compare to its sector?
There are 453 other Technology tickers on Broken Stocks: 293 Red, 95 Amber, 65 Watch, with 52 showing recovering structural signals. Median sector decline is -39.7% — ARM's decline is deeper than the sector median.
Does ARM'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 (2026-11-04) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
