President & COO Novack sold 114,000 DVAX shares at $15.64; -64.3% of holdings. Stock up 44.4% in 30d, 54.5% in 90d.
Novack David F, President & COO of Dynavax, sold 114,000 shares (114.0K shares) at $15.64 on 2026-01-15, reducing his stake from 177,344 to 63,344 shares—a -64.3% reduction in holdings. This sale occurs after significant recent appreciation: the stock has gained 44.4% in the prior 30 days and 54.5% over the prior 90 days, placing the transaction price just -0.2% from the 52-week high of $15.72. Notably, all 5 of Novack's prior sales at DVAX were well-timed at the 90-day mark (all showing negative 90-day returns averaging -7.4%), and his cross-ticker track record shows a 100.00% well-timed rate across 5 prior open-market sells with an average 90-day return of -7.7%. The company's fundamentals show strong growth (annual revenue growth of +19.4%, latest quarterly revenue of $94,876,000.00, net income of $26,927,000.00), though the P/E of 74.67 reflects an elevated valuation. The timing—at a 52-week near-high following a 54.5% run-up—combined with this insider's demonstrated pattern of well-timed exits at this ticker warrants investor attention.
