EVP/CLO Brown sold 10,000 DXCM shares at $84.28 on 2025-05-23; stock now at $86.98 (-31.9% from 52-week high).
Brown Michael Jon, EVP and Chief Legal Officer, sold 10,000 shares of DEXCOM at $84.28, reducing his holdings by 9.5% to 95,602 shares. The sale occurred while the stock was trading significantly below its 52-week high of $127.64, though it has recovered 22.2% over the past 30 days. Across his prior open-market sales at all tickers, Brown's 90-day timing rate was 100%, and at DXCM specifically, 1 of 1 prior sales at the 90-day mark showed negative returns, indicating his historical sales have occurred before subsequent declines. This sale by a senior legal officer represents a reduction in skin-in-the-game at a $34.1B company trading at a P/E of 63.96.
EVP Chief Legal Officer Brown Michael Jon sold 13,000 shares of DXCM at $70.38 on 2025-03-12; stock now down 49.7% from 52-week high.
Brown Michael Jon, EVP and Chief Legal Officer, sold 13,000 shares at $70.38, reducing his stake by 11.0% to 105,602 shares. The sale comes as DXCM trades 49.7% below its 52-week high and down 15.7% over the last 30 days, suggesting the stock has lost significant momentum post-transaction. His cross-ticker track record shows a 100.00% well-timed rate on prior sells—meaning his historical exit timing preceded declines—though prior DXCM-specific activity (one sale in 2024 at the same date) showed a -13.3% 90-day return, indicating that sell was well-timed as the stock declined afterward. The present sale aligns with a pattern of selling ahead of weakness, though the stock's sharp recent deterioration (down 49.7% year-to-date) raises questions about whether the decline is now already reflected in price or signals deeper operational concerns.
