Martin Lyons sold 26,818 shares of Ameren for $3,000,325.12 on 2026-03-03, representing a significant reduction in his holdings from 309,499 to 282,681 shares. The stock was trading near its 52-week high ($111.84 vs. the $113.28 peak) at time of sale, and has since risen 8.4% over 30 days and 10.4% over 90 days. Examining his transaction history at Ameren specifically shows mixed timing outcomes: his 2025 sale preceded a 6.4% decline over 90 days (well-timed), while his 2024 sale was followed by a 3.8% gain (poorly-timed), indicating no consistent pattern at this ticker. His broader cross-ticker track record across 2 prior open-market sales shows an average 90-day return of -1.3% with a 50% well-timed rate, neither demonstrating systematic edge in timing nor raising conviction concerns.
