Methodology note: these Smart Money cards use consecutive 13F disclosure snapshots, not trade-by-trade execution data. "Buying", "selling", "new holders", and "trimmed" refer to quarter-over-quarter changes in reported holders, aggregate shares, or disclosed position values between filings. They are useful for ownership regime analysis and crowding, but they do not imply exact trade timing on the filing date.

Selling streak — 2 quarters in a row: For 2 consecutive quarters, more hedge funds reduced or closed their ISRG positions than added to them. Sustained institutional selling is a meaningful warning sign — these are professionals with deep research teams collectively deciding to exit.
More sellers than buyers — 49% buying: Last quarter: 1,159 funds reduced or exited vs 1,107 that bought or added. When more than half of active funds are selling, it's a caution flag — especially if the stock price hasn't moved down yet.
Elite ownership — 61% AUM from top-100 funds: 71 of 2249 holders are among the 100 largest funds by AUM, controlling 61% of total institutional value in ISRG. When the biggest players dominate the cap table, it signifies deep institutional support — since mega-funds deploy the most rigorous due diligence and capital.
66% of holders stayed for 2+ years: 1,478 out of 2,256 hedge funds have held ISRG for over 2 years without selling. Long-term investors are generally harder to shake out during market stress, creating a stable ownership base that limits the risk of sudden capitulation.
As of today, ISRG has moved +2.7% since the 2026 Q2 13F filing date (August 14, 2026), compared to +2.4% for the XLV sector ETF — an outperformance of +0.3%. Since the quarter end (June 30, 2026), ISRG has gained +1.9% vs +8.0% for XLV. The stock is tracking its sector benchmark closely. The signal remains fresh and the entry point is still near the fund's implied reference.
