What does the ISRG technical analysis show?

As of the August 3, 2026 data cutoff, ISRG technical analysis shows a mixed daily trend, with price back above SMA20 after a sharp late-July decline that touched a new 52-week low near 328.57. The weekly chart is bearish, with the weekly close below all key moving averages. Daily RSI at 49.62 is neutral, while the weekly RSI at 31.62 leans bearish and approaches oversold. The daily MACD histogram is positive, suggesting early momentum improvement, while the weekly MACD histogram remains negative.

What are the key support and resistance levels for ISRG?

ISRG key support is at 328.57, which is the 52-week low, the 20-day low, and the 60-day low. Near-term resistance is at 372.55 (SMA20) and 397.92 (SMA50), with the 20-day high at 443.84 above that. A sustained close above 443.84 would challenge the 60-day high at 462.40. On the weekly chart, the SMA200 at 413.17 now sits above price and acts as resistance.

Is ISRG overbought or oversold based on RSI?

ISRG RSI14 is 49.62 on the daily chart and 31.62 on the weekly chart. Neither timeframe is overbought (above 70). The daily RSI recovered from oversold during the late-July decline and is now neutral, while the weekly RSI is approaching but has not yet reached oversold (below 30). This leaves room for further downside before the weekly reading would be considered technically oversold.

What does the MACD signal for ISRG?

The daily MACD line at -13.80 is above the signal at -15.74, with a positive histogram of 1.94, indicating that downside momentum is easing. The weekly MACD remains bearish, with the MACD line at -35.45, signal at -28.10, and a negative histogram of -7.34, meaning the higher timeframe still shows downward pressure.

Can technical analysis predict the ISRG price?

No, technical analysis cannot reliably predict an exact future price. It identifies trends, momentum, and key price levels based on historical data to inform risk assessment. ISRG price movements will depend on company fundamentals such as da Vinci surgical system procedure volumes, product approvals, competitive dynamics in robotic surgery, macroeconomic conditions, and broader market sentiment. Technical analysis is one tool among many for understanding market conditions.

Multi-timeframe dashboard

Multi-Timeframe Technical Dashboard

Comparing daily (2-year) and weekly (5-year) perspectives to identify aligned or conflicting signals.

Daily (August 3, 2026)

Trend: Mixed. Price at 375.41 is above SMA20 (372.55) but below SMA50 (397.92) and SMA200 (481.57). The SMAs remain in a descending alignment, with SMA200 sloping lower, so the short-term reclaim of SMA20 has not yet changed the longer-term downtrend.
Momentum: Neutral. RSI14 at 49.62 is back in neutral territory after the late-July oversold reading. MACD at -13.80 is above the signal at -15.74 with a positive histogram of 1.94, indicating that downside momentum is easing.
Volatility: Moderate. ATR14 at 15.29 (4.07% of price) reflects above-average daily swings during the volatile late-July decline. Bollinger Bands (314.40 to 430.70) are wide, with price near the upper half after the August 3 rebound.
Volume: Below average. Latest volume of 3,499,800 is 86.1% of the 20-period average (4,064,490), showing that the August 3 rebound attracted less participation than the recent selloff days.

Assessment

The daily chart is mixed after a sharp decline in late July. Price touched a new 52-week low near 328.57, then rebounded 6.25% on August 3 back above SMA20 (372.55). RSI recovered to a neutral 49.62 and the MACD histogram is positive, but the rebound came on below-average volume and price remains below SMA50 (397.92) and SMA200 (481.57). Sustained closes above the SMA50 area would improve the near-term picture, while a move back below 328.57 would put the stock in fresh low territory.

Weekly (July 27, 2026 week)

Trend: Bearish. The weekly close at 353.33 is below SMA20 (424.50), SMA50 (476.25), and SMA200 (413.17). Price has broken below the SMA200, which had provided support earlier in the correction, and the key SMAs are sloping downward.
Momentum: Bearish. RSI14 at 31.62 is approaching oversold territory. MACD at -35.45 is below the signal at -28.10 with a negative and widening histogram of -7.34, confirming persistent downside momentum on the higher timeframe.
Volatility: Moderate. ATR14 at 32.67 (9.25% of price) reflects elevated weekly ranges during the corrective phase.
Volume: Above average. Weekly volume of 17,176,100 is 135.9% of the 20-week average (12,633,350), indicating strong participation in the recent decline.

Assessment

The weekly chart is bearish. The close below the SMA200 (413.17) is a significant structural change, and RSI at 31.62 is approaching oversold without yet showing a reversal signal. The widening negative MACD histogram and above-average volume during the decline suggest the correction is still in progress. A sustained weekly close back above the SMA200 would be the first sign of stabilization.
