Tempus AI Stock Plunges as Ark Invest Trims Position
Tempus AI shares tumbled 12.4% this week after Cathie Wood's Ark Invest reduced its stake in the healthcare AI company. The sell-off erased part of the stock's 161% year-to-date rally, despite recent FDA clearance for its RNA-based diagnostic tool.
Ark Innovation ETF shed 62,352 Tempus shares worth $5.2 million, though the position remains its largest holding at 10.7% of the portfolio. The MOVE signals profit-taking after the stock's meteoric rise, not wholesale abandonment of the AI-driven healthcare thesis.
