Bell Michael Brian

Bell Michael Brian, Chief Financial Officer of Guardant Health (GH), has filed 47 Form 4 transactions with the SEC, all in the single company. The aggregate pattern is decisively one-sided: $8,807,093 in open-market sales and zero dollars in open-market purchases. No shares were acquired through direct buys, and the recent window shows two sales in June 2026—$257,240 on June 5 and a subsequent disposition—against no buys at all. The transaction stream is dominated by mechanical and compensatory events rather than discretionary trading. The most frequent codes are "M" (option exercises, valued at $0) and "F" (shares withheld to cover taxes), which appear in clusters around quarterly vesting dates: July 1, 2026 ($668,393 withheld), April 1, 2026 ($626,109), and January 1, 2026 ($1,274,605). These are automatic, non-discretionary events tied to equity compensation. The only true open-market sales are the two "S" codes—$257,240 on June 5, 2026, and $261,111 on March 16, 2026—which are modest relative to the tax-withholding amounts. The absence of any "P" (purchase) codes across all 47 filings signals a consistent sell-only posture, but the context matters: the overwhelming majority of activity is the routine conversion of vested options into shares, with a portion immediately surrendered to cover tax obligations. The two discretionary sales are small in dollar terms compared to the multi-hundred-thousand-dollar tax withholdings, suggesting the CFO is not aggressively monetizing his position. The pattern is typical of an executive managing a concentrated equity stake through scheduled vesting cycles, with no recent indication of a shift toward accumulation.
