Questions about CENX
What people ask.
Why is CENX on Broken Stocks?
CENX qualifies for the Red List on decline depth. It is down -42.1% from its rolling 252-day high of $70.43, set on 2026-06-02 — 108d ago.
Is CENX a falling knife?
By the most common technical definition — a steep, recent breakdown from a fresh high — yes. CENX is down -42.1% from its 52-week high of $70.43, set 108d 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 — the classification does not predict subsequent returns. Broken Stocks flags the pattern; it does not recommend buying or selling.
Is CENX 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 CENX trading inside its 52-week range?
At $39.01, CENX sits 35.7% of the way from its 52-week low ($21.56) to its 52-week high ($70.43). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
How fast has CENX been declining?
The current 42.1% decline accrued over 108d, which annualizes to roughly -142.3% 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 CENX compare to its sector?
There are 230 other Basic Materials tickers on Broken Stocks: 128 Red, 61 Amber, 41 Watch, with 101 showing recovering structural signals. Median sector decline is -36.2% — CENX's decline is deeper than the sector median.
Does CENX's earnings date affect its tier?
No. Tiering uses decline depth and recency, bearish time-frame structure, and decline sigma. The earnings date on file (2026-08-06) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
