CapitolRadar analysis
59 disclosed ISRG trades split narrowly toward sales
59 tracked trades in Intuitive Surgical span April 17, 2020 through August 10, 2026. The activity consists of 27 buys and 32 sells by three distinct congressional traders, a difference of five transactions in favor of sales. ISRG is classified in Healthcare and the Medical - Instruments & Supplies industry.
The trader count is small, so the aggregate is sensitive to the behavior of each individual. Transaction counts also do not establish the size of holdings, portfolio exposure, investment performance or intent. Congressional disclosures may be filed up to 45 days after a transaction, and disclosed dollar amounts are reported as ranges; any amount-based totals or comparisons derived from those ranges are estimates.
14 recent quarterly trades included five buys
14 trades appear across the reported quarters from 2024 Q4 through 2026 Q3, including five buys and nine sells. The highest quarterly count in this window was three trades, recorded in both 2025 Q1 and 2025 Q3. All three 2025 Q1 trades were sells, while two of the three 2025 Q3 trades were buys.
Activity remained sparse afterward: two trades with one buy in 2025 Q4, two with one buy in 2026 Q1, one buy in 2026 Q2, and one sell in 2026 Q3. With only one to three disclosures in each quarter, quarter-to-quarter changes represent a limited sample rather than a broad trading pattern.
21 of 27 buys came from Ro Khanna
Ro Khanna recorded 21 buys, with the last dated May 1, 2026. Josh Gottheimer recorded four buys, most recently July 22, 2024, while Markwayne Mullin recorded two, most recently December 29, 2025. Khanna therefore accounts for most tracked ISRG purchases.
Among these three buyers, two also bought each of PANW, ADI, FCX and GOOGL. One also bought AMD, and one also bought BBY. These overlaps describe disclosed activity among only three people and do not show that the transactions were coordinated or related to ISRG.
