McKesson’s Stock Plunges 0.28% as $342M Volume Ranks 266th Amid Technical Pressures

On August 18, 2025, McKesson (MCK) closed at $671.19, down 0.28% with a trading volume of $342.90 million, ranking 266th in market activity. The stock fluctuated between $668.50 and $677.00, reflecting a 1.27% intraday range. Recent performance shows a 6.7% decline over 10 days, with technical indicators signaling a bearish short-term trend.

McKesson’s price action aligns with a descending channel, with the 50-day moving average at $668.80 providing near-term support. The stock faces resistance at the 200-day moving average of $703.13. Analysts note conflicting signals: a short-term moving average suggests a buy, while the long-term average indicates a sell. A break below $668.80 could intensify bearish momentum, while a rebound above $703.13 might reverse the trend. Volume contraction during the decline suggests reduced selling pressure, offering limited downside risk.

Key levels include a critical support at $668.58, with a stop-loss recommended at $632.74 (-5.73%). The stock’s average daily volatility of 1.27% and medium risk profile highlight its susceptibility to short-term swings. An upcoming ex-dividend date on September 2, 2025, with a $0.82 payout, may influence near-term positioning but is unlikely to offset broader technical pressures.

Backtesting of a high-volume-driven strategy from 2022 to present yielded a 23.4% cumulative return, with a net profit of $2,340. However, the modest gain underscores the conservative nature of the approach amid market volatility, suggesting limited alpha generation from volume-based entry points alone.
