Questions about ALGN
What people ask.
Why is ALGN on Broken Stocks?
ALGN qualifies for the Amber List on decline depth. It is down -23.7% from its rolling 252-day high of $200.44, set on 2026-04-21 — 141d ago.
Is ALGN a falling knife?
No. The falling-knife label usually implies a steep, severe drop — typically 30% or more from a fresh high. ALGN is down -23.7% 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 ALGN 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 ALGN trading inside its 52-week range?
At $152.92, ALGN sits 39.4% of the way from its 52-week low ($122.00) to its 52-week high ($200.44). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
How fast has ALGN been declining?
The current 23.7% decline accrued over 141d, which annualizes to roughly -61.4% 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 ALGN compare to its sector?
There are 276 other Healthcare tickers on Broken Stocks: 135 Red, 80 Amber, 61 Watch, with 34 showing recovering structural signals. Median sector decline is -35.2% — ALGN's decline is shallower than the sector median.
Does ALGN'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 (2026-07-29) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
