Questions about PLAB
What people ask.
Why is PLAB on Broken Stocks?
PLAB qualifies for the Red List on decline depth. It is down -44.2% from its rolling 252-day high of $56.00, set on 2026-05-11 — 72d ago.
Is PLAB a falling knife?
By the most common technical definition — a steep, recent breakdown from a fresh high — yes. PLAB is down -44.2% from its 52-week high of $56.00, set 72d ago. That combination of depth (past the 30% Amber threshold) and recency (high set inside the last 120 days) is the textbook falling-knife pattern. Whether to try to catch it is a separate question — historically most attempts to bottom-pick continue lower before reversing. Broken Stocks flags the pattern; it does not recommend buying or selling.
Is PLAB 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 PLAB trading inside its 52-week range?
At $31.24, PLAB sits 33.8% of the way from its 52-week low ($18.61) to its 52-week high ($56.00). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
How fast has PLAB been declining?
The current 44.2% decline accrued over 72d, which annualizes to roughly -224.1% 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 PLAB compare to its sector?
There are 237 other Technology tickers on Broken Stocks: 152 Red, 49 Amber, 36 Watch, with 35 showing recovering structural signals. Median sector decline is -40.7% — PLAB's decline is deeper than the sector median.
Does PLAB'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 (2026-05-28) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
