Significance 6/10

Chief Safety Officer sold 30,034 RBLX shares at blended average $72.65; stock now $68.99, -51.3% from 52-week high of $141.56.

Matthew D Kaufman, Chief Safety Officer at Roblox, executed 2 separate sales totaling 30,034 shares for $2,182,104.74 at prices around the blended average of $72.65 on 2026-02-10. The timing carries mixed signals: his cross-ticker track record shows a well-timed sell rate of 71.43% across 13 prior open-market sales (with average 90-day returns of +3.8%), but his five most recent RBLX-specific sales on 2025-11-20 were followed by declines in the 13.4% to 16.6% range over 30 days, suggesting he had been positioned ahead of recent weakness. The current price of $68.99 sits 51.3% below the 52-week high of $141.56, and RBLX is unprofitable (net income of $-255,626,000.00 in the latest quarter) despite strong annual revenue growth of +35.8%. The stock is down 10.1% in the last 30 days and 31.9% in the last 90 days—a period that encompasses both this sale and his November cluster. Investors should note this CSO maintained substantial holdings (307,263 shares post-transaction), but the pattern of selling into a declining stock warrants attention to underlying business momentum.

Significance 7/10

Chief Safety Officer Kaufman sells 20,867 shares for $2.0M at avg $96.10 on 2025-11-20; stock down 36.0% from 52-week high.

Matthew D Kaufman, Chief Safety Officer at Roblox, executed 6 separate sales totaling 20,867 shares for $2,005,238.79 on 2025-11-20 at an average price of $96.10, reducing his holdings by 8.0%. The stock has since declined significantly, trading at $90.58—down 36.0% from its 52-week high of $141.56 and down 29.1% over the past 30 days. Notably, his prior 5 trades at RBLX have all proven well-timed at the 90-day mark, with negative 90-day returns following each sale. His cross-ticker track record shows 7 prior sells with a 71.43% well-timed rate and an average 90-day return of +3.8%, though sell timing at a single ticker is distinct from cross-ticker history. Given the company remains unprofitable (net income $-255,626,000.00 in the latest quarter) despite 28.7% annual revenue growth, this sale warrants attention as part of an established pattern of timely exits at this specific security.

Significance 5/10

Chief Safety Officer sold 20,208 shares of RBLX for $2,373,417.14 across two days at avg $117.45

Matthew D Kaufman, Chief Safety Officer at Roblox, executed 5 separate sales totaling 20,208 shares for $2,373,417.14 on August 20-21, 2025, reducing his holdings from 301,223 shares to 281,015 shares (-6.7%). The sales occurred at prices ranging from $116.05 to $118.67, with a blended average of $117.45, just 0.07 points below the current price of $117.52. His prior two sales at RBLOX (both on 2025-05-20) each produced positive 90-day returns of approximately +47-48%, meaning the stock rose after he sold—a pattern indicating poorly timed exit decisions from a sell-timing perspective. The company remains unprofitable (net income $-278.4M in the latest quarter) despite strong revenue growth of +28.7% year-over-year and a market cap of $81.5B, presenting a mixed fundamental backdrop where the insider's discretionary liquidation provides limited directional signal.

Significance 4/10

Matthew D Kaufman, Chief Safety Officer at Roblox, executed 2 separate sales on 2025-05-20 totaling 15,021 shares for $1,211,520.47. The transactions occurred at a blended average price of $80.66, near the current price of $81.81, which marks the 52-week high. His post-transaction holdings of 331.2K shares represent a 4.3% reduction from his prior 346.2K shares. Roblox revenue reached $1.0B in the latest quarter with annual growth of 28.7%, though the company reported negative net income of $-215.1M and remains unprofitable on a full-year basis. The stock has appreciated 31.6% over the past 30 days and 30.9% over 90 days, meaning the sale occurred at the peak of a significant recent rally.
