Guardant Health Inc stock surged 9.61% to $166.99 in a sharp intraday rally driven by strong second-quarter 2026 results and raised full-year revenue guidance. The company reported 44% year-over-year revenue growth to $335 million and announced a new revenue target range of $1.34 billion to $1.36 billion for the year. The stock opened with a 6.1% gap up and reached an intraday high of $176.58 before settling near $166.99.
