Significance 6/10

Director Seawell A Brooke sold 115,000 shares (100% of holdings) at $24.82 for $2.9M; stock now down -5.4% in 30 days.

Seawell A Brooke, a director at Tenable, executed a complete liquidation of her position, selling all 115,000 shares at $24.82 on 2025-12-15 for $2.9M total value. The timing is notable: the stock has declined -5.4% over the 30 days following the sale and stands -44.6% below its 52-week high of $44.50, suggesting the sale occurred during a period of weakness. Tenable's fundamentals are mixed—revenue grew +12.7% year-over-year to $252.4M last quarter, but the company remains unprofitable on a full-year basis with negative net income. Across her cross-ticker history, Brooke's 20 prior open-market sales show an average 90-day return of +14.9% and a 0.00% well-timed rate, indicating those prior sales were consistently poorly timed (subsequent gains were common). The full exit of board-level holdings warrants attention given the scale and the current valuation pressure, though the pattern does not align with a director signaling conviction.

Significance 6/10

Director Seawell A Brooke sold 12,728 shares of NVDA at $183.93 on 2025-12-02 for $2,341,117.04, exiting position entirely.

Seawell A Brooke, a director, executed a complete liquidation of her NVDA holdings—12,728 shares for $2,341,117.04—on 2025-12-02 at $183.93 per share. The transaction price sits 11.4% below the 52-week high of $207.04 and 5.8% below the current price of $183.38. Across her prior 5 trades at NVDA (all sells in July 2025), none were well-timed at the 90-day mark; the stock advanced an average of 12.1% after those sales. Her cross-ticker track record of 20 prior sells shows a 0.00% well-timed rate, with an average 90-day return of +15.2% following the sales—indicating her sells have historically occurred before rallies, not declines. The full exit at NVDA, combined with a consistent pattern of poorly-timed sales across both this ticker and other holdings, suggests the transaction reflects a discretionary liquidity or portfolio decision rather than a signal of deteriorating conviction in the company's fundamentals, which remain robust with $57.0B in quarterly revenue and net income of $31.9B.

$15,999,906
Significance 6/10

Director A Brooke Seawell sold 96,904 shares of NVDA for $16.0M across 9 transactions (Jul 11–14)

Director A Brooke Seawell executed 9 separate sales totaling 96,904 shares for $15,999,906.22 across July 11–14, reducing her holdings from 1.83M to 1.73M shares (-5.3%). The sales were executed at prices ranging from $162.67 to $167.79, with a blended average of $165.11, while NVDA's current price stands at $170.70 near its 52-week high. The stock has appreciated +20.2% over 30 days and +63.4% over 90 days, reflecting sustained strong momentum. Seawell has a track record of 20 prior open-market sells across all tickers, though prior outcomes at NVDA specifically are not yet measurable. The transaction's significance is tempered by the modest reduction (5.3%) relative to total holdings and the lack of discernible pattern in timing relative to recent NVDA momentum.

Sell
148,402 shares
$23,999,797
Significance 7/10

NVDA Director A. Seawell sold 148,402 shares for $23,999,797.19 in 8 sales over 3 days (Jul 8-10).

Director Seawell executed 8 separate sales totaling 148,402 shares for $23,999,797.19 across July 8–10, 2025, at prices ranging from $159.04 to $164.30 (blended average $161.72), while NVDA's current price stands at $164.10. The sales reduced her holdings by 7.5%, from 1,974,784 shares to 1,826,382 shares, yet she retains substantial equity exposure. The timing of these sales occurred during a period of significant stock appreciation—NVDA is at its 52-week high (+0.0% from peak) and has gained 14.0% over 30 days and 47.9% over 90 days. The director's same-ticker history shows 5 prior sales in early July (2025-07-02 and 2025-07-07), all outcomes still unmeasurable. With NVDA trading at a P/E of 52.10 against $44.1B annual revenue and 114.2% year-over-year growth, the stock reflects substantial valuation momentum rather than distress, making this a large-scale liquidation of a meaningful but minority stake at elevated price levels.

Significance 6/10

Director Seawell A Brooke sold 101,925 shares for $15,999,789.46 across 7 transactions (blended avg $156.98) on 2025-07-02 and 2025-07-07.

On 2025-07-02 and 2025-07-07, Director Seawell A Brooke executed 7 separate sales totaling 101,925 shares for $15,999,789.46, reducing holdings from 2,076,709 to 1,974,784 shares (-4.9% of pre-transaction holdings). The blended average transaction price of $156.98 occurred within NVDA's tight 52-week range context, where the stock currently trades at $158.24 (-0.7% from the $159.34 52-week high) and has appreciated 11.7% over 30 days and 64.3% over 90 days. The director has 5 prior transactions at NVDA (all in the 2 days prior: 2025-07-01), with outcomes not yet measurable, and a cross-ticker track record of 20 prior open-market sells. The sales occurred while NVDA maintains strong fundamentals: $44.1B latest-quarter revenue, $18.8B net income, 114.2% annual revenue growth, and a P/E of 50.23. This represents a significant dollar-value exit by a board member, but without information on whether the sales are scheduled or discretionary, the timing relative to subsequent price movement cannot be characterized.

Significance 4/10

NVDA director Seawell A Brooke sells 102,652 shares for $15,999,848.40 over two days (6/30–7/1)

Seawell A Brooke, a director at NVIDIA, executed 9 separate sales totaling 102,652 shares for $15,999,848.40 at a blended average price of $155.86 per share across June 30 and July 1, 2025. This represents a -6.1% reduction in her holdings to 1,576,709 shares. The current price of $153.30 is -3.0% from the 52-week high of $157.99, and the stock has gained 13.4% over 30 days and 38.8% over 90 days. The director's cross-ticker track record shows 20 prior sells, but the timing of her same-ticker history at NVDA (5 prior trades, all recent) is not yet measurable. This multi-day, multi-tranche sale occurs within a context of strong recent stock appreciation and elevated valuation (P/E of 48.67), though the filing itself contains no scheduled trading plan notation and no indication of forced liquidation or material adverse circumstances.

Significance 7/10

Director Seawell A Brooke sold 155,209 shares across 11 transactions for $23,999,683.01 (June 25–27).

Director Seawell A Brooke executed 11 separate sales totaling 155,209 shares for $23,999,683.01 over three trading days (June 25–27), at prices ranging from $149.97 to $158.43 and a blended average of $154.63. This represents an 8.5% reduction in her NVDA holdings, bringing her position from 1,834,570 shares to 1,679,361 shares. The transaction occurred as the stock trades at $157.75, near its 52-week high, with strong recent momentum (+17.0% over 30 days, +43.8% over 90 days). Seawell's cross-ticker track record shows a 100.00% well-timed rate on prior sells, though her 10 prior sales averaged -88.9% and -88.7% returns over 30 and 90 days respectively—meaning she sold before subsequent declines. At NVDA specifically, her five prior trades (all sells on June 23–24) lack measurable outcomes, providing no history to assess her timing accuracy at this ticker.

Significance 7/10

Director SEAWELL A BROOKE sold 165,430 shares across 9 transactions (June 20–24) for $23,999,734.56 at blended avg $145.07

Director SEAWELL A BROOKE executed 9 separate sales totaling 165,430 shares (1.83M shares remaining post-transaction, -8.3% reduction) between June 20–24, 2025, at prices ranging from $142.95 to $147.77, netting $23,999,734.56. The sale volume and multi-tranche execution over 4 days represents a substantial portfolio reduction. Stock price context: the current price of $147.90 sits near the 52-week high of $149.43 (-1.0%), and has climbed +12.6% in 30 days and +30.0% in 90 days. Relevant to timing assessment: this insider's single prior NVDA sale (May 28, 2024) yielded -88.9% and -88.7% returns at 30 and 90 days respectively—a well-timed sell (stock fell after). Cross-ticker track record shows 1 prior sell with identical 30/90-day returns and a 100.00% well-timed rate, though sample size is minimal. Fundamentals remain robust: $44.1B quarterly revenue with +114.2% annual growth, $18.8B net income, and 46.95 P/E on a $3,608.8B market cap.
