Is Intuitive Surgical Stock Paying You Enough For The Swings?
For questions about this article or underlying research, email help@trefis.com.
For investors holding Intuitive Surgical (ISRG), maker of da Vinci surgical robots, the stock likely sits alongside capital that already tracks the broader market. The shares can swing sharply, rising 9.4% in a single session on November 4, 2026. Large price movements add turbulence to a broader portfolio, meaning the stock’s returns must compensate for the added volatility. So how much return has the stock paid you for sitting through those swings?
Intuitive Surgical Has Paid You Less, With Bigger Swings
Over the five years from November 1, 2021, to November 9, 2026, Intuitive Surgical returned 5.3% a year, trailing the 11.9% annual return of the S&P 500. Shareholders also endured much wider price movements to achieve those gains. The stock’s annual volatility, a measure of how widely its price moves over a year, was 34.9%, compared with 17.1% for the index.
Dividing the yearly return by the volatility shows the compensation for each unit of swing: 0.152 for Intuitive Surgical, against 0.696 for the S&P 500. A higher figure indicates better returns relative to the price swings. Over those five years, the stock paid out far less for its turbulence than the index did.
How Intuitive Surgical Moves When The S&P 500 Moves
Over the past year, from November 6, 2025, to November 9, 2026, Intuitive Surgical fell 93% as much as the S&P 500 on an average down day for the index. When the index rose, the stock captured only 67% of the average daily gain. For a $10,000 holding, a typical down day erased about $58.60, while a typical up day added about $44.20.
The stock also experienced much wider swings over the past year, recording a volatility of 35.6% against 13.7% for the index. However, its beta, measuring how far it moves for each move in the index, was 0.93, meaning the stock did not magnify broader market fluctuations. Its daily changes aligned with the index only loosely, showing a correlation of 0.36 where 1 indicates moving in lockstep. Most of its extra swing came from independent price moves.
Price Cuts And A Pending Settlement At Intuitive Surgical
Intuitive Surgical is in the middle of several changes to its business. Management expects its pricing actions, together with a policy-driven price cut in China, to lower da Vinci instrument and accessory revenue per procedure by about 3% to 5% once fully in place, with procedure and product mix held constant.
The company has also agreed to a $450 million litigation settlement that still needs court approval, a decision management does not expect until 2027. The settlement is with U.S. customers in a class action over third-party remanufacturing of da Vinci instruments and third-party servicing of da Vinci systems. Growth has been slower in the U.S. than abroad: da Vinci procedures grew 10% there in fiscal Q3 2026, against 20% outside the U.S. Intuitive Surgical is expected to report again in January 2027, when management plans to update its estimate of the long-term opportunity in soft tissue surgery.
Compared with an index fund, Intuitive Surgical has delivered smaller gains on the market’s up days, matched nearly all of the index’s losses on down days, and introduced large independent swings on any given day. For investors who already hold other bets on how many surgeries are performed, the stock adds to that same bet rather than spreading risk. U.S. da Vinci procedure growth is the measure to watch in that January report.
