Questions about SUPN
What people ask.
Why is SUPN on Broken Stocks?
SUPN qualifies for the Watch on decline depth. It is down -20.5% from its rolling 252-day high of $59.68, set on 2026-02-25 — 176d ago.
Is SUPN a falling knife?
No. The falling-knife label usually implies a steep, severe drop — typically 30% or more from a fresh high. SUPN is down -20.5% 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 SUPN 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 SUPN trading inside its 52-week range?
At $47.45, SUPN sits 31.8% of the way from its 52-week low ($41.76) to its 52-week high ($59.68). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
How fast has SUPN been declining?
The current 20.5% decline accrued over 176d, which annualizes to roughly -42.5% 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 SUPN compare to its sector?
There are 143 other Healthcare tickers on Broken Stocks: 70 Red, 35 Amber, 38 Watch, with 50 showing recovering structural signals. Median sector decline is -36.1% — SUPN's decline is shallower than the sector median.
Does SUPN'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 (2026-08-03) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
