The structural read

What price action says about CENX.

CENX qualifies for the Red List on decline depth — down -36.6% from its rolling 252-day high. Past 30% with the high set inside the last four months — the recency clause that often precedes further breakdown. Depth plus recency: this is the pattern many investors call a falling knife.

Upstream TFC read: weak alignment, current phase daily. Last bar types — daily 2U (red), weekly 1 (red), monthly 2D (green).

Questions about CENX

What people ask.

Why is CENX on Broken Stocks?

CENX qualifies for the Red List on decline depth. It is down -36.6% from its rolling 252-day high of $70.43, set on 2026-06-02 — 38d ago.

Is CENX a falling knife?

By the most common technical definition — a steep, recent breakdown from a fresh high — yes. CENX is down -36.6% from its 52-week high of $70.43, set 38d 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 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 $44.67, CENX sits 50.9% of the way from its 52-week low ($18.00) 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 36.6% decline accrued over 38d, which annualizes to roughly -351.6% 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 75 other Basic Materials tickers on Broken Stocks: 44 Red, 19 Amber, 12 Watch, with 14 showing recovering structural signals. Median sector decline is -38.3% — CENX's decline is shallower than the sector median.

Does CENX'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 (2026-05-07) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
