Questions about OSIS
What people ask.
Why is OSIS on Broken Stocks?
OSIS qualifies for the Watch on decline depth. It is down -29.1% from its rolling 252-day high of $311.72, set on 2026-04-21 — 37d ago.
Is OSIS a falling knife?
No. The falling-knife label usually implies a steep, severe drop — typically 30% or more from a fresh high. OSIS is down -29.1% 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 OSIS 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 OSIS trading inside its 52-week range?
At $221.16, OSIS sits 15.9% of the way from its 52-week low ($204.00) to its 52-week high ($311.72). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
How fast has OSIS been declining?
The current 29.1% decline accrued over 37d, which annualizes to roughly -287.1% 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 OSIS compare to its sector?
There are 179 other Technology tickers on Broken Stocks: 114 Red, 45 Amber, 20 Watch, with 115 showing recovering structural signals. Median sector decline is -42.2% — OSIS's decline is shallower than the sector median.
Does OSIS'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 (2026-05-04) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
