EVP Catherine T. Doherty sells 5,558 DGX shares at $206.21 for $1.1M; holds 67.1K post-sale

Doherty, an EVP at Quest Diagnostics, sold 5,558 shares at $206.21 on 2026-03-05, reducing her holdings by 7.6% to 67.1K shares. The sale occurred near the stock's 52-week high of $211.91, with DGX currently trading at $199.21, down 6.0% from that peak but up 5.3% over 30 days and 9.2% over 90 days. Doherty's cross-ticker track record shows 7 prior sells with a 0.00% well-timed rate at the 90-day mark (all prior sells were followed by positive returns), and her 5 prior DGX sales on 2026-02-13 remain unmeasured in outcome; this March sale occurs in a context where her timing accuracy across tickers has been consistently poor. The fundamentals—$2.8B quarterly revenue, +11.8% annual growth, and a reasonable 20.08 P/E—offer no obvious deterioration that would explain the sale as responsive to business concerns.

EVP Doherty sold 26.2K DGX shares for $5.4M across 5 trades on 2026-02-13, reducing holding by 27.8%

Catherine T. Doherty, EVP of Regional Businesses at Quest Diagnostics, executed 5 separate sales totaling 26,165 shares for $5,393,814.70 on 2026-02-13, with a blended average price of $206.15. This represents a substantial 27.8% reduction in her post-transaction holdings from 94,233 to 68,068 shares. The sales occurred near the stock's 52-week high of $209.32 (current price $205.49), in a period of strong momentum (+8.4% over 30 days, +10.5% over 90 days). However, her prior two sales at DGX (both on 2024-11-27) were followed by positive 90-day returns of +8.2% and +7.5%, indicating these earlier exits preceded stock appreciation rather than declines, with a 0% well-timed rate at the 90-day mark at this ticker. The transaction merits tracking to determine whether the elevated price level near the recent high represents a similar pattern or a meaningful shift in the executive's view of valuation.

EVP Catherine Doherty sells 33,103 shares at $162.99 avg for $5.4M, reducing holdings by 32.6%

Catherine Doherty, EVP of Regional Businesses, executed 2 separate sales totaling 33,103 shares for $5,395,484.41 on 2024-11-27, reducing her holdings from 101,515 shares to 68,412 shares. The sales occurred at prices ($162.14 and $163.13) very close to the 52-week high of $163.89, with the blended average of $162.99 representing near-peak valuations. The 32.6% reduction in her position is substantial, though she retains meaningful ownership of 68,412 shares post-transaction. DGX stock is trading 1.4% below its 52-week high and has posted modest gains over 30 and 90 days (+4.0% and +2.9% respectively), while the company faces headwinds reflected in annual revenue decline of -6.4% and a P/E of 21.45.
