Across his cross-ticker sell history, Schmidt's 20 prior open-market sales averaged a 90-day post-sale return of +58.5%, and his five prior transactions at Vicor (all on 2026-05-04) each generated positive 30-day and 90-day returns ranging from +25.1% to +33.4%, establishing a pattern of selling before price appreciation. Because this transaction is scheduled under a 10b5-1 plan rather than discretionary, the trade reflects pre-determined execution rather than market-timing judgment.

Vicor Corp VP Claudio Tuozzolo sells 3,000 shares at $328.41; retains 13,240 shares plus 26,913 options

Claudio Tuozzolo, Corporate Vice President at Vicor Corp, sold 3,000 shares on 2026-05-26 at $328.41 for total value of $985,239.00, reducing his non-derivative holdings from 16,240 to 13,240 shares (-18.5%). His derivative holdings (26,913 non-qualified stock options) remain intact, representing a substantial ongoing economic interest in the company. Notably, across his five prior sales at Vicor, none were well-timed at the 90-day mark; all five prior sales were followed by stock price increases of 9.3% to 20.2%, indicating the insider has historically sold before rallies rather than peaks. The current stock price of $345.84 is +3.4% from the 52-week high of $334.62 and has risen 28.8% over 30 days and 68.2% over 90 days since this transaction date, continuing the pattern of post-sale appreciation observed in his prior trades at this ticker. With a P/E of 68.21 and annual revenue growth of 26.1%, the company shows strong operational momentum; this partial reduction appears to constitute a scheduled equity transaction rather than a conviction-driven exit.

VP Marketing Robert Gendron sells 4,571 shares of VICR for $1,508,430 across 6 transactions at $330.00

Robert Gendron, Corporate VP of Marketing at Vicor, sold 4,571 shares of VICR across 6 separate transactions totaling $1,508,430 at a blended average price of $330.00 on 2026-05-26. His non-derivative holdings are now at zero, though he retains 11,036 shares in derivative holdings (non-qualified stock options across 6 vehicles). This represents a scheduled vest-and-sell event of his non-derivative position rather than an overall exit, as the derivatives remain outstanding. The current stock price of $345.84 is 3.4% above the 52-week high of $334.62, and the stock has risen 28.8% over the past 30 days and 68.2% over 90 days, placing this sale at elevated valuation levels relative to the 52-week range. Vicor's fundamentals show strong momentum with annual revenue growth of 26.1%, a 68.21 P/E ratio, and recent quarterly revenue of $113.0M with net income of $20.7M.

VP and CIO Doyle Alvaro exercises and immediately sells 4,041 shares for $1.16M; repeats pattern of zero net gain after offset transactions.

Doyle Alvaro, Vice President and CIO of Vicor, exercised options on 4,041 shares and sold all of them on the same day, netting approximately $1.16M and leaving his net shareholding unchanged. This is a routine equity-plan liquidation: the exercise and sale offset entirely, suggesting the transaction was a tax-efficient or cash-management maneuver rather than a reflection of confidence in the stock. Critically, Alvaro's track record at this ticker tells a cautionary story — all five of his prior sales saw the stock rise afterward, meaning he has never timed a sale well at this company, consistently exiting before further gains. The stock has rallied sharply over the past three months and currently trades modestly below its 52-week high, a backdrop where his historical pattern of early exits continues. While the company itself is profitable with expanding revenues, Alvaro's repeated sales without any offsetting open-market purchases across 36 months of filings underscore a consistent one-directional stance: liquidating rather than accumulating.

Vicor Corp VP Tuozzolo exercises then immediately sells all shares for ~$2.7M, leaving zero net position.

Claudio Tuozzolo, Vice President and Director at Vicor, exercised roughly 8,984 shares in two tranches on the same day and immediately sold all of them for approximately $2.7 million in total proceeds—a classic cashless exercise pattern where the insider captures no economic stake. This move is particularly notable given the stock's dramatic 30-day rally: Tuozzolo's sales came precisely as the stock was near its 52-week highs after an extraordinary two-month surge, suggesting he seized the opportunity to monetize while the momentum peak was in place. Looking at his own history at Vicor, prior sales over the last three months have been well-timed in the near term but showed mixed results over longer horizons—most recently his April sales failed to avoid the subsequent rally. This transaction is Tuozzolo's 32nd and 33rd open-market sale across all Form 4 filings in the trailing 36 months, underscoring a consistent pattern of liquidating equity rather than accumulating it. The company remains financially sound and profitable, but the zero-net-position exit combined with timing at stretched valuations suggests the VP is simply harvesting compensation value without retaining belief in the stock at current levels.

General Manager exercises options worth ~$1M and sells all shares same-day for ~$5.8M gain at 52-week highs.

Michael McNamara, General Manager of Manufacturing Operations at Vicor, exercised three tranches of options and sold all resulting shares on the same day while the stock traded near its 52-week highs. The transactions generated a gain of approximately $4.7 million between acquisition and disposition prices, reflecting the substantial appreciation of his underlying option positions. McNamara has no prior open-market purchases in the 36-month window and has relied exclusively on stock-based compensation for his holdings; this exercise-and-sell is his third open-market sale in that period. His two prior sales at this stock both proved poorly timed—the share price rose in the months following each exit—a pattern that may suggest his timing judgment has been off before, though the near-term price rally may have created attractive opportunity to liquidate at peak levels. The underlying company is profitable with solid revenue growth, but trades at a notably elevated multiple, so a decision to harvest gains at highs carries different weight than panic selling into weakness.
