At the same ticker (MCK), his prior five trades show mixed post-sale outcomes: two measurable 90-day results (+11.9% and +14.2% in earlier 2025 sales), indicating the stock has generally risen after his prior sales at this company rather than fallen. His cross-ticker track record across 20 prior sells shows an average 90-day return of +6.0% and a 33.33% well-timed rate, revealing that sales have historically underperformed as the underlying stocks advanced. The current transaction follows a sale just seven days prior (2025-08-15) at the same ticker, suggesting active liquidation rather than isolated positioning decisions.

MCK CEO Tyler Brian S. sells 11,930 shares ($8.1M) at $677.76; reduces holdings 42.8% post-transaction.

Tyler Brian S., CEO of McKesson, sold 11,930 shares on 2025-08-15 at $677.76, reducing his holdings from 27,872 shares to 15,942 shares—a 42.8% reduction in stake.

Examining his same-ticker history at MCK: of 3 prior sales with measurable 90-day outcomes, zero were well-timed (all showed positive returns post-sale, meaning he sold before subsequent gains). His cross-ticker track record shows 0 of 20 prior sales were well-timed at the 90-day mark—a pattern of selling into strength rather than declining prices. The company's fundamentals remain solid with $97.8B in annual revenue and 16.2% YoY growth, suggesting the sale reflects portfolio positioning rather than fundamental distress.

CEO Tyler Brian S. sold 19,371 (19.4K) MCK shares at $708.09 for $13,716,411.39 on 2025-07-11, reducing holdings by 41.0%

At the current price of $715.57, the stock is -2.7% from its 52-week high and trading within 2.5% of the transaction price. His same-ticker track record at MCK shows five prior sells, none of which were well-timed at the 90-day mark; all four measurable prior sales saw positive 90-day returns, suggesting the CEO sold before meaningful gains materialized. His cross-ticker track record across 20 prior sells shows an average 90-day return of 6.0% and a 33.33% well-timed rate, indicating below-average predictive timing on his sales decisions. The company's fundamentals remain strong—revenue of $95,294,000,000.00 and annual revenue growth of 16.2%—with a P/E of 28.70. Without scheduled plan disclosure or additional context, this sale represents a significant discretionary reduction in the CEO's equity stake in the company.

CEO Tyler Brian S. sold 19,370 MCK shares at $705.93 for $13.7M, reducing holdings 27.4%

Tyler Brian S. sold 19,370 shares of MCKESSON CORP on 2025-06-06 at $705.93, representing a material reduction of 27.4% of his pre-transaction holdings from 70,613 to 51,243 shares. The stock traded near its 52-week high of $726.40 at the time of sale and has shown strong momentum, with 90-day returns of +8.4%. However, his prior sales at MCK reveal a consistent pattern of poor timing: all 5 previous sales at this ticker generated positive 90-day returns (+7.7%, +7.1%, +10.6%, +8.3%, +11.9%), meaning the stock rose significantly after each sale—0 of 5 were well-timed by the sell-timing standard. His cross-ticker track record shows only a 33.33% well-timed rate across 20 prior sells, below the baseline for effective timing discipline. The company fundamentals remain solid with $95.3B in annual revenue, +16.2% growth, and a P/E of 28.41, providing no obvious distress signal independent of the transaction itself.

MCK CEO Tyler Brian S. sold 8,962 shares at $634.24 on 2025-03-06 (value $5.7M), reducing stake 17.3% to 42.7K shares.

TYLER BRIAN S., Chief Executive Officer, sold 8,962 shares at $634.24 on 2025-03-06, totaling $5,684,058.88. The sale reduced his holdings from 51,703 shares to 42,741 shares, representing a 17.3% reduction in pre-transaction holdings. At the transaction price of $634.24, the stock was 0.0% from its 52-week high of $644.53, suggesting the sale occurred near peak valuation. The insider has a mixed track record: his cross-ticker record shows a 60.00% well-timed rate on prior sells (avg 90d return -1.7%), but at MCK specifically, only 1 of 2 prior measurable sales was well-timed at the 90-day mark. The three most recent MCK sells (2025-02-28, 2025-02-21, 2025-02-14) lack outcome data. With MCK trading at a P/E of 28.57 and showing strong recent momentum (+6.2% in 30 days, +6.7% in 90 days), this large reduction of CEO holdings warrants observation for any signal about near-term confidence, though the clustering of three sales within the past two weeks suggests possible scheduled disposition rather than a single discretionary event.

CEO Tyler Brian S. sold 8,961 shares of MCK at $624.00 (Feb 28); holds 51.7K shares post-sale

Tyler Brian S., MCK's CEO, sold 8,961 shares on 2025-02-28 at $624.00, reducing his holdings from 60.7K to 51.7K shares (a 14.8% reduction). The transaction occurred near MCK's 52-week high of $644.53, within a month of the stock's +8.4% 30-day climb. Among his prior MCK sales, 2 of 3 with measurable 90-day outcomes were well-timed (negative 90-day returns, indicating he sold before declines). However, his recent sales pattern at MCK shows two additional sells on 2025-02-14 and 2025-02-21 with outcomes not yet measurable—suggesting a recent elevated cadence of equity dispositions. His broader cross-ticker sell history shows an average 90-day return of -1.7% with a 60% well-timed rate, indicating a mixed but moderately favorable historical timing record across all positions. The sale's proximity to the 52-week high and the acceleration of recent sales merit monitoring for potential signaling.
