Significance 7/10

Director Tuan Sherman sold 48,630 shares of SMCI at $33.00 (Nov 26); stock now at $33.41, down 45.0% from 52-week high.

Tuan Sherman, a Director, executed an open-market sale of 48,630 shares at $33.00, reducing his holdings by 19.0% from 255,786 to 207,156 shares. The sale price falls within the depressed range of the stock's current trajectory: at $33.00 on the transaction date, SMCI was already well below its 52-week high of $60.71 (representing a 45.0% decline from the peak) and has continued sliding, now at $33.41 after a 30-day decline of 35.7%. His prior transaction history at SMCI shows a consistent pattern: all 5 of his prior SMCI sales occurred on 2024-02-29 and achieved negative 90-day returns (average 90-day performance: -90.4%), with 100% of his prior SMCI sells classified as well-timed. His cross-ticker track record similarly reflects strong sell-timing discipline, with a 90-day well-timed rate of 100.00%. This current sale occurs in the context of SMCI's recent weakness and aligns with the insider's demonstrated pattern of executing sales ahead of further declines.

Significance 7/10

SMCI SVP George Kao sells 56,904 shares at $32.83 (-45.9% from 52-week high); 90-day sell pattern 80% well-timed at this ticker

George Kao, SVP of Operations, sold 56,904 shares of Super Micro Computer at $32.83 on 2025-11-24, reducing his holdings by 29.7% from 191,595 to 134,691 shares. The stock is trading 45.9% below its 52-week high and down 36.3% over the past 30 days. His prior transaction history at SMCI shows a strong pattern: 4 of 5 previous sells resulted in negative 90-day returns (well-timed sells before subsequent declines), most notably sales on 2024-02-05 and 2024-02-15 where the stock fell 82.7% and 89.2% respectively over the following 90 days. This timing pattern at SMCI—combined with the current 29.7% reduction in position size during a period of significant stock weakness—warrants attention as a material insider trade at a $19.6B market-cap company with strong recent fundamentals (46.6% annual revenue growth, $5.0B quarterly revenue).

Significance 6/10

SMCI CFO David Weigand sells 25,000 shares at $45.14; stock down 26.0% from 52-week high amid strong fundamentals (46.6% revenue growth, $4.6B quarterly revenue).

David E. Weigand, SVP and Chief Financial Officer of Super Micro Computer, Inc., executed an open-market sale of 25,000 shares at $45.14 on 2025-09-15, reducing his holdings from 125,188 to 100,188 shares (a -20.0% reduction). The sale occurs as SMCI is trading down 26.0% from its 52-week high of $60.71, despite the company reporting robust fundamentals: $4.6B in latest quarterly revenue, net income of $108.8M, and annual revenue growth of +46.6%. Weigand's prior trades at SMCI show a mixed timing pattern: 2 of 3 measurable sales have been well-timed at the 90-day mark (producing negative 90-day returns as the stock subsequently fell), but his most recent May 2025 sale saw the stock appreciate +4.2% over 90 days. The current sale at $45.14 comes just 12 days after two separate sales on 2025-09-03, suggesting an active trimming phase during a period of elevated price decline.

Significance 6/10

CFO WEIGAND sells 25,000 SMCI shares (25.0K shares) for $1.0M at $40.29 avg; stock down 33.4% from 52-week high.

David E. Weigand, SVP and Chief Financial Officer, executed two separate sales totaling 25,000 shares for $1,007,280.67 on 2025-09-03, reducing his holdings by 20.0% to 100,188 shares. The transaction occurred at a blended average price of $40.29, while the current price stands at $40.41 and the stock is -33.4% from its 52-week high of $60.71. His prior trades at SMCI show a strong pattern of timing acumen: 4 of 5 prior sells resulted in negative 90-day returns, demonstrating well-timed exits before subsequent declines. The company's fundamentals remain solid with annual revenue growth of +46.6% and a P/E of 22.96, yet the stock is off 13.6% over the past 30 days, warranting attention to whether this sale reflects forward-looking concerns or routine portfolio management by a major shareholder.

Significance 7/10

SMCI SVP George Kao sells 40,000 shares ($1.8M) at $43.88; stock now -28.9% from 52-week high, post-sale holdings cut 64.7%

George Kao, SVP of Operations at Super Micro Computer, sold 40,000 shares on 2025-08-22 for $1,755,200.00, reducing holdings by 64.7% (from 61,820 to 21,820 shares). The sale occurred at $43.88, and SMCI has since declined 18.6% over 30 days and sits 28.9% below its 52-week high of $62.38. Kao's prior five sales at SMCI show a strong pattern: 4 of 5 were well-timed at the 90-day mark, including three consecutive sales in late 2023 and early 2024 with 90-day declines ranging from -75.2% to -90.4%. However, his most recent SMCI sale (2025-05-14) has posted only -9.4% over 30 days, suggesting the pattern may be shifting. His broader cross-ticker record spans 6 prior sells with an 83.33% well-timed rate at the 90-day horizon, though recent 30-day performance (-18.6% post-current-sale) aligns with his cross-ticker average of -65.6% at 30 days. Given the substantial position reduction, the negative near-term price action, and his mixed recent timing at this ticker, this sale merits investor attention to whether the 4-of-5 historical accuracy at SMCI persists.

Significance 6/10

Director Liu Liang Chiu-Chu Sara sold 200,000 shares of SMCI at $60.00 for $12,000,000 on 2025-07-28

Director Liu sold 200,000 shares at $60.00 while SMCI trades at $60.71, just 14.8% below its 52-week high of $71.22. The sale follows a 23.9% surge in the 30-day period and an 85.5% rally over 90 days, reducing her holdings from 40.63M to 40.43M shares (a 0.5% reduction). Her cross-ticker track record shows 5 prior sells with a well-timed rate of 100.00%, and at SMCI specifically, 2 of 2 measurable prior sells generated negative 90-day returns (-31.7% and -88.6%), suggesting a pattern of selling before declines. However, the most recent SMCI sale on 2025-06-18 was followed by a +15.0% 30-day return, indicating variable timing outcomes. The company posted $4.6B revenue with +110.4% annual growth and net income of $108.8M, but the P/E of 31.46 reflects elevated valuation relative to historical and peer multiples.

SMCI CEO Liang Charles sold 200,000 shares at $60.00 on 2025-07-28; price since up 23.9% in 30 days, 85.5% in 90 days.

Liang Charles, President and CEO of Super Micro Computer, sold 200,000 shares at $60.00 on 2025-07-28, reducing his holdings from 40.63M to 40.43M shares (a -0.5% reduction in position size). The sale occurred at a price that has since declined to $60.71 current price, representing -14.8% from the 52-week high of $71.22, while the stock has posted +23.9% gains in the 30-day period and +85.5% gains over the 90-day period since the sale. His cross-ticker track record shows 5 prior sells with an average 90-day return of -37.3% and a 90% well-timed rate, but at this specific ticker (SMCI), his prior 2 measurable 90-day outcomes were both well-timed declines (-17.1% and -57.4%), though recent same-ticker sales in June, May, and February have shown mixed results as the stock has rebounded significantly. This sale occurs within a fundamentally strong context: SMCI posted $4.6B in latest quarterly revenue, $108.8M net income, annual revenue growth of +110.4%, and a market cap of $36.2B. The timing of this insider sale during a sharp post-transaction rally creates a mismatch between the insider's action and subsequent price momentum, warranting scrutiny of whether the sale reflects broader confidence or operational liquidity needs.

SMCI CEO Liang Charles sold 300,000 shares ($13.5M) at $45.00 on 2025-06-18; stock down 50.7% from 52-week high of $92.00.

Liang Charles, President and CEO, divested 300,000 shares (0.4% of post-transaction holdings of 66.90M shares) at $45.00, capturing $13,500,000 in proceeds amid significant stock weakness. The stock now trades 50.7% below its 52-week high of $92.00, though it has recovered +8.8% over the past 30 days and +7.5% over 90 days. Examining his historical pattern: across all tickers, his prior 4 sells averaged -33.6% return at 30 days and -37.3% at 90 days, with a 100.00% well-timed rate at the 90-day horizon—meaning those sales consistently preceded further declines. At SMCI specifically, his prior 4 trades (two distinct sales on 2025-05-14, and earlier sales on 2025-02-26 and 2023-12-05) showed 90-day returns of -17.1% and -57.4% respectively, with 2 of 2 measurable 90-day outcomes being well-timed. Despite the stock's recent 30- and 90-day gains, the CEO's demonstrated pattern of selling into strength before subsequent weakness, combined with the stock's current 50.7% drawdown from peak, warrants investor scrutiny of forward guidance and demand fundamentals.

Director Liu Liang Chiu-Chu Sara sold 300,000 shares of SMCI at $45.00 for $13,500,000; price -50.7% from 52-week high of $92.00.

Director Liu sold 300,000 shares at $45.00 on June 18, 2025, representing a 0.4% reduction in holdings but a substantial absolute value of $13.5M. The transaction occurred with SMCI trading significantly below its 52-week high of $92.00, though the stock has recovered +8.8% over 30 days and +7.5% over 90 days from that sell point. Examining Liu's track record at SMCI specifically, prior sells on February 26, 2025 and December 5, 2023 were both well-timed at the 90-day mark (posting -17.1% and -57.4% returns respectively), establishing a historical pattern of selling before declines at this ticker. The company's fundamentals show strong revenue growth at +110.4% annually and recent quarterly revenue of $4.6B, though recent sales at lower prices ($45.00 vs. the prior $92.00 high) may reflect valuation reassessment rather than company deterioration.

Significance 7/10

CFO David Weigand sold 67,000 SMCI shares ($2.9M) at $44.02; repeats 5-year pattern of well-timed exits before declines

David Weigand, SVP and CFO, sold 67,000 shares (43.1% of his pre-transaction holdings) on 2025-05-20 at $44.02, reducing his position from 155.6K to 88.6K shares. His prior 5 trades at SMCI were all well-timed sells: every one recorded negative 90-day returns, ranging from -57.4% to -76.8%. His cross-ticker track record shows a 100.00% well-timed rate across 5 prior sells with average 90-day return of -69.3%, indicating consistent pattern recognition in identifying opportune exit windows. The stock has since fallen to $41.32 (current price is -55.1% from its 52-week high of $92.00 and -26.3% over the 90-day period), placing this sale again in line with that historical pattern, though timing assessment at this filing date remains early.
