Questions about PNR

What people ask.

Why is PNR on Broken Stocks?

PNR qualifies for the Amber List on decline depth. It is down -36.9% from its rolling 252-day high of $113.06, set on 2025-10-03 — 237d ago.

Is PNR a falling knife?

Not by the strict technical definition. PNR is down -36.9% from its 52-week high, but that high was set 237d ago — more than 120 days. A falling knife is usually a recent breakdown from a fresh high, not an established multi-quarter downtrend. PNR is still on the Amber List for decline depth, but the freshness component of a falling knife is missing.

Is PNR 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 PNR trading inside its 52-week range?

At $71.33, PNR sits 1.4% of the way from its 52-week low ($70.73) to its 52-week high ($113.95). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.

How fast has PNR been declining?

The current 36.9% decline accrued over 237d, which annualizes to roughly -56.8% 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 PNR compare to its sector?

There are 137 other Industrials tickers on Broken Stocks: 57 Red, 33 Amber, 47 Watch, with 83 showing recovering structural signals. Median sector decline is -30.7% — PNR's decline is deeper than the sector median.

Does PNR'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 (2026-04-28) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
