Questions about PTEN
What people ask.
Why is PTEN on Broken Stocks?
PTEN qualifies for the Amber List on decline depth. It is down -28.2% from its rolling 252-day high of $13.08, set on 2026-05-18 — 53d ago.
Is PTEN a falling knife?
No. The falling-knife label usually implies a steep, severe drop — typically 30% or more from a fresh high. PTEN 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 PTEN 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 PTEN trading inside its 52-week range?
At $9.39, PTEN sits 19.4% of the way from its 52-week low ($8.50) to its 52-week high ($13.08). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
How fast has PTEN been declining?
The current 28.2% decline accrued over 53d, which annualizes to roughly -194.2% 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.
