Questions about PI

What people ask.

Why is PI on Broken Stocks?

PI qualifies for the Amber List on decline depth. It is down -35.4% from its rolling 252-day high of $247.06, set on 2025-10-24 — 300d ago.

Is PI a falling knife?

Not by the strict technical definition. PI is down -35.4% from its 52-week high, but that high was set 300d ago — more than 120 days. A falling knife is usually a recent breakdown from a fresh high, not an established multi-quarter downtrend. PI is still on the Amber List for decline depth, but the freshness component of a falling knife is missing.

Is PI 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 PI trading inside its 52-week range?

At $159.73, PI sits 45.3% of the way from its 52-week low ($87.36) to its 52-week high ($247.06). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.

How fast has PI been declining?

The current 35.4% decline accrued over 300d, which annualizes to roughly -43.1% 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 PI compare to its sector?

There are 239 other Technology tickers on Broken Stocks: 148 Red, 49 Amber, 42 Watch, with 65 showing recovering structural signals. Median sector decline is -36.8% — PI's decline is shallower than the sector median.

Does PI'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 (2026-07-29) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
