Intuitive Surgical stock closed at USD 393.33 on Nasdaq on September 18, 2026, rising 2.6 percent from the prior session according to closing data from MarketBeat and other market portals. The advance left the shares trading well below their one-year high and year-start level despite the positive day.
September 18, 2026 in numbers
Intuitive Surgical Inc. (ISIN US46120E6023, Nasdaq: ISRG) ended the September 18, 2026 session at USD 393.33 on Nasdaq, with MarketBeat quoting a one-year trading range between USD 328.57 and USD 603.88 and a year-to-date decline of 30.6 percent from the USD 566.36 level recorded at the start of 2026, based on data updated on September 20, 2026. Per the same MarketBeat overview, the closing price on September 18, 2026 at 4:00 p.m. Eastern Time reflected a 2.55 percent daily gain, implying a previous close near USD 383.54, and positioned the stock closer to its one-year low than its high for now. An analysis reported by Ad-hoc-news noted the same USD 393.33 close on September 18, 2026 and highlighted the stock's roughly USD 135.50 billion market capitalization in mid-September 2026, underlining its large-cap status and the scale of the recent drawdown versus the year-start level.
While detailed intraday high, low and volume figures for September 18, 2026 are less prominently summarized in the available portals, the confirmed close and one-year range frame the session as a rebound day within a broader downward path for 2026. The quantified decline of 30.6 percent from USD 566.36 at the beginning of the year to USD 393.33 on September 18, 2026, compared with the one-year low of USD 328.57 and one-year high of USD 603.88, shows that the stock has retraced a substantial portion of its prior gains even after the latest daily rise. In comparison, the Nasdaq Composite index also gained on September 18, 2026, according to the general market data cited by MarketBeat for that date, indicating that Intuitive Surgical participated in a wider technology and growth-stock advance rather than diverging sharply from the broader market in that session.
Outlook today and into October 2026
Looking ahead to today, September 21, 2026, investors are focused less on an immediate scheduled company event and more on the next quarterly update that will follow in October. According to the earnings calendar and forecast overview at AltIndex, Intuitive Surgical is expected to report its next earnings on October 19, 2026, with the analyst consensus pointing to earnings per share of USD 1.63 for the upcoming quarter. A separate calendar on MarketBeat estimates the next earnings around October 20, 2026, but both sources cluster the reporting window in the second half of October 2026, making that period the next major fundamental catalyst for the shares.
Against this backdrop, today's trading ahead of the Nasdaq open on September 21, 2026 will likely be shaped by broader movements in healthcare and technology indices, as well as shifts in expectations for interest rates and economic data that influence valuations of growth-oriented medical technology companies. The confirmed rebound on September 18, 2026, together with the stock's position closer to its one-year low than its high and the substantial year-to-date decline, provides the numerical context for how Intuitive Surgical enters today's session, while the upcoming October earnings date outlined by AltIndex and MarketBeat sets the next clear checkpoint for company-specific news flow.
