Technical commentary — 2026-08-03

ISRG closed at $375.41 today, reflecting a 6.25% gain that shifted the composite technical signal from strong-bearish to a bullish +6.3/100. This movement coincided with the price crossing a detected support or resistance level during the session. The bullish shift is supported by the Parabolic SAR, which now sits below the price, and a MACD (12/26/9) that remains above its signal line with positive histogram readings. Despite these developments, the volume category remains a strong bearish -65.0/100, driven by a bearish divergence where the price moved upward while the On-Balance Volume trended lower. Current relative volume sits at 0.86× the average.

The stock is currently hovering just 0.2% above its nearest support level of $374.70, which has been tested once. Conversely, the nearest resistance lies at $474.29, marking a 26.3% distance from the current close after 28 historical touches. While the price structure category is strong bullish at +60.0/100, the broader trend shows lingering weakness as the price remains below the 200-day moving average and the 20-day moving average stays below the 50-day moving average. These technical indicators describe the current state of price action and historical volume but do not indicate future direction or causal relationships.

The current technical posture is defined by a conflict between bullish trend signals and a bearish volume divergence. Momentum indicators including the RSI, Stochastic, and CCI remain in neutral territory, offering no clear signal regarding the strength of the recent price move. The stock is positioned near its support floor as it attempts to move away from recent lows.
