Why Upstart Stock Just Went Down Instead

Shares of artificial intelligence-powered fintech provider Upstart (NASDAQ: UPST) got shook up on Tuesday, down 10% as of 3 p.m. EDT after investment bank Jefferies revoked its buy rating on the stock and downgraded Upstart to hold. The analyst also worries that at present valuations -- it has a $25 billion market cap -- Upstart's stock price already "reflects strong and successful market penetration in the personal and auto loan categories over the next few years."
