Technical commentary — 2026-08-05

McKesson Corporation (MCK) closed today at $877.23, marking a 5.64% increase that triggered a shift in the composite technical signal from strong-bearish to strong-bullish at +12.9/100. This rally resulted in the price crossing a detected support/resistance level during the session. While the price structure category registers as strong-bullish at +60.0/100, the momentum category remains neutral with an RSI of 61.8 and Stochastic %K at 69.8. Volume activity also contributed to the upward move, as the OBV divergence confirms the price trend despite relative volume sitting at 0.99× the average.

The stock is currently trading above its MA200, and the bullish lean is reinforced by the MA20 sitting above the MA50. Nearest resistance is positioned at $904.20, which is 3.1% above current levels and has seen six touches, while nearest support rests at $852.56 with 11 confirmed touches. Although the price position within the Bollinger band is at 87%, other indicators like the Parabolic SAR remain in a bearish lean with the indicator positioned above the price. These technical readings describe historical price action and volume relationships rather than future performance. The trend category currently holds a bearish score of -10.0/100, primarily influenced by the MACD histogram remaining negative and the price being below the signal line.

The composite signal shift reflects a divergence between the bullish price structure and the underlying bearish trend indicators like the MACD and Parabolic SAR. Momentum indicators remain anchored in the neutral range, providing no clear directional bias. Current data highlights the proximity to the $852.56 support level, which continues to influence the price structure assessment.
