Casper Mark, EVP & CLO, sells 10,000 MRVL shares at $135.50; stock rallies +72.1% in 30 days
Casper Mark sold 10,000 shares of Marvell at $135.50 on 2026-04-17, reducing his holdings by 21.8% to 35.9K shares. The stock has since rallied sharply—gaining 72.1% over the subsequent 30 days and 83.3% over 90 days, now trading at $151.31, the high end of its 52-week range. His cross-ticker track record shows a 50.00% well-timed rate on prior sells (only 1 of 2 prior MRVL sales measurable), with those outcomes mixed: a +10.4% 30-day return and +30.9% 90-day return following a prior sale, alongside a -13.5% 30-day and -58.0% 90-day return from an earlier trade. The company's fundamentals remain strong—$2.1B quarterly revenue, 42.1% annual growth, and a P/E of 21.93—providing no obvious deterioration signal. This sale occurred amid a period of elevated stock momentum and marked the third such transaction by Mark within 16 days (April 1, 2, and 6), suggesting a pattern of staged liquidation rather than a single discretionary event.
