Questions about CNX
What people ask.
Why is CNX on Broken Stocks?
CNX qualifies for the Red List on decline depth. It is down -22.2% from its rolling 252-day high of $43.62, set on 2026-03-06 — 83d ago.
Is CNX a falling knife?
No. The falling-knife label usually implies a steep, severe drop — typically 30% or more from a fresh high. CNX is down -22.2% 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 CNX 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 CNX trading inside its 52-week range?
At $33.93, CNX sits 39.1% of the way from its 52-week low ($27.72) to its 52-week high ($43.62). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
How fast has CNX been declining?
The current 22.2% decline accrued over 83d, which annualizes to roughly -97.6% 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 CNX compare to its sector?
There are 20 other Energy tickers on Broken Stocks: 9 Red, 6 Amber, 5 Watch, with 5 showing recovering structural signals. Median sector decline is -31.9% — CNX's decline is shallower than the sector median.
Does CNX'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 (2026-04-30) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
