Questions about ISRG
What people ask.
Why is ISRG on Broken Stocks?
ISRG qualifies for the Watch on decline depth. It is down -29.1% from its rolling 252-day high of $603.88, set on 2026-01-07 — 127d ago.
Is ISRG a falling knife?
No. The falling-knife label usually implies a steep, severe drop — typically 30% or more from a fresh high. ISRG 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 ISRG 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 ISRG trading inside its 52-week range?
At $428.06, ISRG sits 0.1% of the way from its 52-week low ($427.84) to its 52-week high ($603.88). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
How fast has ISRG been declining?
The current 29.1% decline accrued over 127d, which annualizes to roughly -83.6% 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 ISRG compare to its sector?
There are 182 other Healthcare tickers on Broken Stocks: 93 Red, 43 Amber, 46 Watch, with 55 showing recovering structural signals. Median sector decline is -35.8% — ISRG's decline is shallower than the sector median.
Does ISRG'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 (2026-04-21) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
