IDEAYA Holds Steady Heading Into ASCO—Traders Watch for Next Mover on IDYA
IDEAYA Biosciences edged higher in a holiday-shortened week, finishing Friday at $29.47, up 0.4%. Shares added about 1.3% from the previous week’s close. Investors shrugged off an employee stock-option grant and focused on cancer-drug results expected at ASCO this week. U.S. stock trading paused Monday for Memorial Day, leaving the week with only four sessions. Markets are closed again for the weekend. According to Nasdaq’s 2026 holiday calendar, May 25 will also be a full closure for Memorial Day.
