Gilead CEO O'Day sells ~$1.3M in stock as shares pull back from recent highs

CEO Daniel Patrick O'Day sold approximately $1.3 million in Gilead stock across two transactions, disposing of roughly 1.6% of his holdings in a single day. The timing is notable: the stock has pulled back noticeably from its recent highs and sits meaningfully below where it traded three months ago, suggesting O'Day is selling into weakness rather than at peak valuations. While Gilead remains a financially healthy, profitable company with strong revenue generation, this sale by the top executive during a down period could signal either portfolio rebalancing or a cautious view on near-term momentum. The modest reduction in his stake—less than 2% of total holdings—indicates this is not a wholesale liquidation, but it does represent a net reduction in his personal conviction at a time when the stock faces headwinds.

O'Day sells 10,000 GILD shares at $136.82; holds 642.6K post-trade. Stock down 12.5% from 52-week high.

O'Day Daniel Patrick, Chairman & CEO, sold 10,000 shares of Gilead on 2026-03-27 for $1,368,162.00 ($1.4M), reducing holdings by 1.5% to 642.6K shares.

His prior four sales at this ticker (all on 2026-02-27 and 2026-02-05) occurred weeks earlier and show mostly negative 30-day returns ranging from -7.9% to -4.0%, with one prior sale on 2026-01-28 posting +6.2%. Across his full cross-ticker open-market history, his 20 prior sales show an average 90-day return of +9.1% and a well-timed rate of 0.00%, indicating his historical sales have not preceded stock declines. The company maintains solid fundamentals: $7.8B quarterly revenue, $3.1B net income, and a 10.49 P/E ratio with a $169.3B market cap.

Mercier (Chief Comm Officer, GILD) sold 28,000 shares at avg $154.44; holds 120,288 shares post-sale.

Johanna Mercier sold 28,000 shares (18.9% of pre-transaction holdings) across three separate transactions on 2026-02-17 for a blended average price of $154.44, reducing her stake to 120,288 shares. The sales occurred near the 52-week high ($155.80), with current price at $152.74. Her same-ticker history at GILD shows 5 prior sells, none of which were well-timed at the 90-day mark; the most recent sales in November 2025 and August 2025 were followed by positive 90-day returns of +23.2%, +22.8%, +5.2%, and +5.6%, indicating the stock rose after her previous exits. While Mercier's cross-ticker track record shows an average 90-day return of +10.0% after sells with a 0.00% well-timed rate, her consistent pattern of selling into strength at this ticker, combined with prior unsuccessful timing calls, provides limited signal about near-term direction.

O'Day (Chairman & CEO) sold 115.6K shares of GILD at $150.00 for $17.3M; retains 613.9K shares.

Chairman Daniel Patrick O'Day sold 115,640 shares at $150.00 on 2026-02-05, representing a -15.9% reduction from his 729,552 pre-transaction holdings to 613,912 shares post-transaction.

O'Day's cross-ticker selling track record shows 17 prior sales with an average 90-day post-sale return of 7.7% (positive returns, indicating poorly timed exits), though his 90-day well-timed rate stands at 0.00%. At GILD specifically, prior sales on 2025-12-29 and 2026-01-23/28 have generated mixed results: the December sale showed a 30-day gain of 11.9%, while the most recent January sales remain unmeasurable. The company fundamentals remain solid (P/E 23.32, net income of $3.1B on $7.8B revenue, 6.0% annual growth), with market cap at $189.2B.
