Chang Stephen Chunping Sell
Chief Executive Officer
14,884 shares
$512,987
@ $34.47
Significance 4/10

CEO sells 14,884 shares at $32.90–$34.90 as AOSL rebounds 91.6% in 30 days from recent lows

Stephen Chunping, CEO of Alpha & Omega Semiconductor, executed 3 separate sales totaling 14,884 shares for $512,986.60 on 2026-04-17, reducing his holdings by 2.3% to 635,901 shares. The sales occurred at prices ($32.90–$34.90, blended average $34.47) well below the current price of $39.90, which marks the 52-week high and represents a 91.6% gain over the prior 30 days and 84.1% gain over 90 days. This transaction took place as AOSL stock recovered sharply from depressed levels (52-week low $16.25) but remains unprofitable, with the most recent quarter showing negative net income of $-13,293,000.00 on revenue of $162,263,000.00. The rapid stock appreciation and CEO's decision to liquidate a portion of his position after the recent surge warrants examination of whether this reflects confidence maintenance or opportunistic redeployment of capital during a recovery phase.

Liang Yifan Sell
CFO and Corp Secretary
26,517 shares
$810,495
@ $30.57
Significance 6/10

CFO Liang Yifan sold 26,517 shares for $810,495.24 in 3 transactions at AOSL as stock surges 47.1% in 30 days

Liang Yifan, CFO and Corporate Secretary of Alpha & Omega Semiconductor, executed 3 separate open-market sales on 2026-04-14, totaling 26,517 shares (26.5K shares) for $810,495.24 at prices ranging from $29.00 to $32.00 with a blended average of $30.57, reducing his holdings by 8.7% to 278,628 shares. The sale occurs as the stock trades near its 52-week high ($31.21 current vs $31.95 high) and has appreciated 47.1% over the prior 30 days and 38.6% over 90 days—a sharp recent rally. His prior trade history at AOSL shows strong execution timing: 4 of 5 prior sells resulted in negative 90-day returns (stock fell after he sold), with his prior December 2024 AOSL sales showing declines ranging from -18.8% to -44.6% in the following 90 days, suggesting pattern recognition of market peaks. Against this backdrop, the current sale near 52-week highs following a 47.1% monthly surge warrants attention as a potential data point about near-term valuation levels, particularly given the company is unprofitable on a full-year basis (net income -$13.3M) despite modest revenue growth of 5.9% year-over-year.

Chang Mike F Buy
33,727 shares
$640,813
@ $19.00
Significance 5/10

Director Chang Mike F bought 33,727 shares of AOSL at $19.00 on 2026-03-09 amid unprofitability and recent stock weakness.

Director Chang Mike F purchased 33,727 shares at $19.00, adding to his post-transaction holdings of 4,369,574 shares. The stock is trading at $20.12, down 37.0% from its 52-week high of $31.95, with a 90-day decline of 9.4%. Alpha & Omega Semiconductor reported a net loss of $-13,293,000 in its latest quarter and remains unprofitable on a full-year basis, despite modest annual revenue growth of 5.9%. This buy occurs during a period of operational losses and depressed valuation relative to historical levels, but does not in itself confirm the transaction was motivated by conviction rather than portfolio mechanics or scheduled activity.

Liang Yifan Sell
CFO and Corp Secretary
31,004 shares
$1,525,621
@ $49.21
Significance 6/10

CFO Liang Yifan sells 31,004 shares at blended avg $49.21 for $1.5M while firm unprofitable

Liang Yifan, CFO and Corporate Secretary, executed 4 separate sales totaling 31,004 shares for $1,525,620.92 on 2024-12-04, reducing his holdings by 10.5% (from 296.2K to 265.2K shares). The stock has appreciated 76.4% over the past 30 days and 47.1% over 90 days from lower levels, moving to within 3.9% of its 52-week high of $49.16; the insider's blended sale price of $49.21 sits just above that high. Notably, the company remains unprofitable on a full-year basis with net income of $-2.5M, annual revenue growth of -4.9%, and the most recent quarter showed a loss of $2.5M against $181.9M in revenue. Historically at this ticker, the insider's 3 prior sales (March 2024) were all poorly timed in retrospect—the stock rose 23.5% to 30.4% in the 90 days following those sales—suggesting this insider has not successfully timed exits at AOSL.
