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.

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.

VICR VP Tuozzolo exercises options and sells all acquired shares on same day, netting $1.7M with zero net position change.

Claudio Tuozzolo, Vice President and Director at Vicor, exercised stock options totaling over 6,000 shares and immediately sold all of them on the same trading day, resulting in zero net change to his holdings. The exercise-and-sell pattern—particularly the stark contrast between acquisition costs averaging around $47 per share and sale prices near $277—represents a significant liquidity event of nearly $1.7 million, but it does not reflect conviction about the stock's direction or value. This outcome aligns with Tuozzolo's broader trading pattern: his five prior sales at this ticker were all well-timed in the 30-day period following each trade, though results were mixed over the longer 90-day horizon, with the stock declining modestly after his most recent April sales. Against fundamentals showing a profitable, revenue-growing company trading at a premium valuation multiple, Tuozzolo's exercise-and-immediately-sell approach suggests liquidity extraction rather than any statement about stock prospects. The stock itself has rallied sharply in recent months while remaining below its 52-week high, a backdrop in which option exercises followed by full liquidation are routine portfolio management rather than a noteworthy signal.

VP Tuozzolo sells 11,035 shares ($3.0M) at blended $270.50; holdings down 45.5% to 13.2K; stock near 52-week high

Claudio Tuozzolo, Corporate Vice President of Vicor Corp, executed two separate sales on 2026-04-24 totaling 11,035 shares for $2,985,015.76 at a blended average price of $270.50, reducing his holdings from 24,275 shares to 13,240 shares (a 45.5% reduction). The sales occurred while the stock was trading within 1.8% of its 52-week high of $273.53, and following a 75.5% surge over the prior 30 days. At the same ticker, Tuozzolo's five prior trades (all in late February 2026) show consistent negative 30-day returns ranging from -12.0% to -23.1%, with 90-day outcomes still not measurable. Across his cross-ticker open-market history, his 18 prior sells achieved only an 18.18% well-timed rate (lower than coin-flip accuracy), averaging -9.6% returns in the 30 days post-sale. The company's fundamentals are solid—26.1% annual revenue growth, $110.4M quarterly revenue, and $28.3M net income—but the P/E of 37.20 places valuation at an elevated level.

Corp VP Tuozzolo sells 4,643 shares at $197.85 avg for $918.6K; stock near 52-week high of $205.64

Tuozzolo executed 3 separate sales totaling 4,643 shares for $918,632.64 at a blended average price of $197.85, reducing his holdings by 16.5% to 23,544 shares. The sales occurred with the stock trading near its 52-week high of $205.64 and following a sharp 25.4% gain over 30 days and 130.2% surge over 90 days. At vicr specifically, his cross-ticker track record shows an 18.18% well-timed sell rate with an average 90-day return of +47.3%, though his 1 prior same-ticker sale on 2025-11-12 was not well-timed, posting a +66.4% 90-day return (the stock rose significantly after his sale). Fundamentally, the company reported -11.4% annual revenue growth with a high P/E of 67.42, which may provide context for valuation at such elevated price levels.

VP Tuozzolo sells 5,296 shares at avg $179.43 for $950.3K, reducing holdings by 17.1% at near 52-week highs

Claudio Tuozzolo, Corporate Vice President of Vicor Corp, executed 3 separate sales totaling 5,296 shares (5.3K shares) for $950,274.18 ($950.3K) at blended average price of $179.43 on 2026-02-24. The transactions reduced his holdings from 30,948 shares to 25,652 shares, a net reduction of 17.1%. The sales occurred at a price point that matches the stock's 52-week high of $197.16 (current price is $197.16, within 0.0% of 52-week high). Notably, this sale follows a 90-day surge of 120.2% and 30-day gain of 24.4%, positioning these sales at an elevated price level. His prior same-ticker trades have shown limited success—one prior measurable sell on 2026-02-25 resulted in a +66.4% 90-day return, indicating the stock continued rising after that sale. The broader context: VICR shows declining annual revenue (-11.4%) despite a high P/E of 64.64, which may warrant attention given the valuation environment and growth trajectory.

VP Tuozzolo sells 4,469 shares of VICR at $174.60 for $780.3K; stock now at $190.30 (52-wk high), up 24.1% in 30 days.

Tuozzolo, a Corporate Vice President, sold 4,469 shares (-13.3% of pre-transaction holdings) at $174.60 on 2026-02-23, with the stock subsequently rising to the 52-week high of $190.30. This sale occurred during a period of strong momentum: the stock gained 24.1% over the preceding 30 days and 112.5% over 90 days. His cross-ticker track record across 14 prior sells shows an average 90-day return of +47.3%, indicating a pattern where the stock typically rose after his sales—a poorly-timed pattern. At this same ticker (VICR), his prior two measurable sales on 2025-11-12 saw the stock rise 66.4% over 90 days, reinforcing that this insider's selling has not preceded declines. The company's fundamentals show revenue declined 11.4% year-over-year and the stock trades at a P/E of 62.39, yet the stock has accelerated sharply higher since the November sales and the February transaction occurred within that rally.

VP Tuozzolo sold 6,404 shares at $94.58 across 5 transactions on 2025-11-12 for $605,689.68.

Tuozzolo, a Corporate Vice President at Vicor, executed 5 separate sales on 2025-11-12, totaling 6,404 shares at a blended average price of $94.58, reducing his holdings from 40,026 shares to 33,622 shares (-16.0%). The sales occurred near the 52-week high of $94.88, just 6 basis points below the peak. His cross-ticker track record shows 6 prior sells with a 90-day well-timed rate of 100.00% and an average 90-day return of -58.8%, indicating historically strong sell-side timing discipline. At Vicor specifically, his only measurable prior sale (2025-07-28) delivered a 90-day return of -57.9%, well-timed by definition. The stock has since appreciated 65.1% over 30 days and 85.9% over 90 days from the transaction date—a sharp reversal from his historical pattern of selling into weakness. Fundamentals show annual revenue declining 11.4% year-over-year against a P/E of 29.04, suggesting elevated valuation risk. The convergence of near-peak-price execution, strong prior sell-timing discipline, deteriorating top-line growth, and high valuation multiples warrants investor attention to management's capital deployment confidence relative to near-term cash generation outlook.

VP Tuozzolo sells 14,637 shares for $1.3M at $91.86; exits 30.3% of holdings near 52-week high.

Claudio Tuozzolo, Corporate Vice President, executed four separate sales totaling 14,637 shares (14.6K shares) for $1,344,625.08 ($1.3M) on 2025-10-23 at $91.86, reducing his holdings from 48,259 shares to 33,622 shares—a -30.3% reduction. The sales occurred near the 52-week high of $92.98, just -3.2% below peak. Within the context of his open-market history across all tickers, Tuozzolo's prior 2 sells averaged -29.6% returns over 30 days and -58.8% over 90 days, with a 90-day well-timed rate of 100.00%, indicating his past sales have consistently preceded stock declines. At VICR specifically, both prior sells (2023-07-28 and 2023-07-27) posted negative 90-day returns of -28.9% and -59.7%, establishing a pattern of well-timed exits at this ticker. The timing of this current sale into strength—following the 30-day +84.9% and 90-day +96.8% rallies—aligns with his demonstrated track record of selling before downturns.
