Why is Personalis stock sliding today?

Personalis (PSNL) stock fell 2.8% after BTIG downgraded it to Neutral, removing the $16.25 price target. The analyst believes the Tempus AI acquisition will close at the agreed price, with little chance of improvement. BTIG also concluded that the board prioritized deal speed over a higher bid, despite interest from Merck. The S&P 500 and other indices rose, but Personalis' decline was stock-specific.
