Questions about CELC
What people ask.
Why is CELC on Broken Stocks?
CELC qualifies for the Red List on decline depth. It is down -41.7% from its rolling 252-day high of $151.02, set on 2026-05-04 — 78d ago.
Is CELC a falling knife?
By the most common technical definition — a steep, recent breakdown from a fresh high — yes. CELC is down -41.7% from its 52-week high of $151.02, set 78d 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 CELC 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 CELC trading inside its 52-week range?
At $89.17, CELC sits 55.7% of the way from its 52-week low ($11.28) to its 52-week high ($151.02). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
How fast has CELC been declining?
The current 41.7% decline accrued over 78d, which annualizes to roughly -195.1% 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 CELC compare to its sector?
There are 148 other Healthcare tickers on Broken Stocks: 69 Red, 40 Amber, 39 Watch, with 25 showing recovering structural signals. Median sector decline is -34.5% — CELC's decline is deeper than the sector median.
Does CELC'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 (2026-05-14) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
