Dickson sold 20,519 shares at $169.97 on 2026-02-09, reducing her position from 41,642 to 21,123 shares (−49.3% of prior holdings). The sale occurred at $169.97 while the current price stands at $173.43, near the 52-week high of $173.43, placing this transaction just 1.9% below the recent peak. Her cross-ticker track record shows 20 prior sells with an average 30-day return of −0.5%, though same-ticker history at MMM (4 measurable prior sales) consistently posted small negative 30-day returns (−0.5% to −0.6%), with none yet measurable at the 90-day horizon. The magnitude of this reduction—nearly half her MMM position—alongside execution near peak valuation suggests deliberate portfolio adjustment, though the company's P/E of 36.90 and modest revenue growth of +1.5% year-over-year provide context for sector positioning.
