Peter Y Chung

Director Peter Y Chung sold 43,268 shares (86.5% of holdings) of MTSI at $378.20 for $16.4M on 2026-05-14

Peter Y Chung divested 43,268 shares, reducing his holdings from 50,049 to 6,781 shares—a substantial 86.5% reduction of his prior position. The sale occurred at $378.20 per share during a period of strong price momentum (30-day change +28.6%, 90-day change +45.1%), though the stock remains 11.2% below its 52-week high of $401.24. Across his cross-ticker trading history, Chung's prior sells showed weak timing (average 90-day return +4.8%, well-timed rate 50%), suggesting his historical executions have been split between opportune and inopportune exits. The company's fundamentals present a mixed picture: quarterly revenue of $288,955,000 and quarterly net income of $46,331,000 are solid, with annual revenue growth of 32.6%, but the company was unprofitable on a full-year basis and trades at an elevated P/E of 153.56 on a $27.2B market cap. The scale of this director-level divestment—retaining only 6.8K shares—merits monitoring for signals about insider conviction, particularly given the company's profitability challenges despite strong recent revenue trajectory.

Director CHUNG PETER Y sold 78,479 shares of ATEN at $16.59; prior ATEN sell in May 2024 was well-timed as stock fell 14.6% in 90 days.

Director CHUNG PETER Y sold 78,479 shares at $16.59 on 2024-11-13, reducing holdings by 12.7% to 540,687 shares. This is his second open-market sale at ATEN; his prior sale on 2024-05-20 proved well-timed, with the stock declining 14.6% over the subsequent 90 days. His cross-ticker sell track record shows a 100.00% well-timed rate across all tickers, indicating a pattern of exiting before downturns. The stock has gained 25.0% in the past 90 days and trades near its 52-week high of $16.68, creating potential headwind for timing evaluation on this current transaction. Investors should monitor whether this sale precedes a similar post-transaction decline as observed in his May 2024 transaction.
