Questions about PRTA
What people ask.
Why is PRTA on Broken Stocks?
PRTA qualifies for the Watch on decline depth. It is down -23.5% from its rolling 252-day high of $11.80, set on 2026-05-08 — 104d ago.
Is PRTA a falling knife?
No. The falling-knife label usually implies a steep, severe drop — typically 30% or more from a fresh high. PRTA is down -23.5% 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 PRTA 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 PRTA trading inside its 52-week range?
At $9.03, PRTA sits 46.6% of the way from its 52-week low ($6.61) to its 52-week high ($11.80). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
How fast has PRTA been declining?
The current 23.5% decline accrued over 104d, which annualizes to roughly -82.5% 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 PRTA compare to its sector?
There are 143 other Healthcare tickers on Broken Stocks: 70 Red, 35 Amber, 38 Watch, with 50 showing recovering structural signals. Median sector decline is -36.1% — PRTA's decline is shallower than the sector median.
Does PRTA'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.
