Questions about OSIS
What people ask.
Why is OSIS on Broken Stocks?
OSIS qualifies for the Amber List on decline depth. It is down -30.0% from its rolling 252-day high of $311.72, set on 2026-04-21 — 121d ago.
Is OSIS a falling knife?
Not by the strict technical definition. OSIS is down -30.0% from its 52-week high, but that high was set 121d ago — more than 120 days. A falling knife is usually a recent breakdown from a fresh high, not an established multi-quarter downtrend. OSIS is still on the Amber List for decline depth, but the freshness component of a falling knife is missing.
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 $218.10, OSIS sits 18.2% of the way from its 52-week low ($197.27) 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 30.0% decline accrued over 121d, which annualizes to roughly -90.5% 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 OSIS 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% — 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.
