Smart Money Convergence

ISRG does not currently show a 13F-and-insider convergence signal — its insider confidence score is 0/100, below the threshold this product uses to flag combined buying pressure.

13F data as of 2026-09-30 quarterly filings. Note: many large institutions file close to the 45-day post-quarter deadline, so early-quarter flow figures can shift substantially as more filings arrive.

Intuitive Surgical amended its bylaws on July 23, 2026. The changes tighten rules for shareholder nominations: they now require that anyone proposing a director nominee must hold 67% of shares to comply with SEC universal proxy rules. Other tweaks include clearer disclosure rules, a ban on nominating more candidates than open seats, and changing the voting standard to a majority of votes cast (excluding abstentions and broker non-votes). There's also a technical change that forced a color change for proxy cards used by shareholders soliciting proxies.
