Questions about ST
What people ask.
Why is ST on Broken Stocks?
ST qualifies for the Amber List on decline depth. It is down -22.2% from its rolling 252-day high of $53.89, set on 2026-06-03 — 78d ago.
Is ST a falling knife?
No. The falling-knife label usually implies a steep, severe drop — typically 30% or more from a fresh high. ST is down -22.2% 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 ST 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 ST trading inside its 52-week range?
At $41.93, ST sits 1.2% of the way from its 52-week low ($41.79) to its 52-week high ($53.89). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
How fast has ST been declining?
The current 22.2% decline accrued over 78d, which annualizes to roughly -103.9% 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.
