Questions about CNR

What people ask.

Why is CNR on Broken Stocks?

CNR qualifies for the Watch on decline depth. It is down -28.2% from its rolling 252-day high of $114.80, set on 2026-03-30 — 44d ago.

Is CNR a falling knife?

No. The falling-knife label usually implies a steep, severe drop — typically 30% or more from a fresh high. CNR is down -28.2% 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 CNR 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 CNR trading inside its 52-week range?

At $82.41, CNR sits 37.0% of the way from its 52-week low ($63.36) to its 52-week high ($114.80). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.

How fast has CNR been declining?

The current 28.2% decline accrued over 44d, which annualizes to roughly -233.9% 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 CNR compare to its sector?

There are 22 other Energy tickers on Broken Stocks: 9 Red, 3 Amber, 10 Watch, with 4 showing recovering structural signals. Median sector decline is -28.8% — CNR's decline is shallower than the sector median.

Does CNR'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.
