Questions about CF
What people ask.
Why is CF on Broken Stocks?
CF qualifies for the Watch on decline depth. It is down -23.5% from its rolling 252-day high of $141.38, set on 2026-03-30 — 93d ago.
Is CF a falling knife?
No. The falling-knife label usually implies a steep, severe drop — typically 30% or more from a fresh high. CF is down -23.5% 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 CF 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 CF trading inside its 52-week range?
At $108.16, CF sits 49.2% of the way from its 52-week low ($75.42) to its 52-week high ($141.96). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
How fast has CF been declining?
The current 23.5% decline accrued over 93d, which annualizes to roughly -92.2% 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 CF compare to its sector?
There are 68 other Basic Materials tickers on Broken Stocks: 40 Red, 18 Amber, 10 Watch, with 16 showing recovering structural signals. Median sector decline is -36.7% — CF's decline is shallower than the sector median.
Does CF'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 (2026-08-05) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
