Shares of Teladoc Health Inc. (TDOC) plummeted 5.12% in Monday's pre-market trading session following a bearish analyst report. The significant drop comes as Jefferies, a prominent financial services company, lowered its price target for the telehealth giant.

Jefferies reduced its price target for Teladoc from $10 to $8, while maintaining a Hold rating on the stock. The downgrade was primarily attributed to deteriorating data trends in BetterHelp, Teladoc's mental health service platform. This adjustment reflects growing concerns about the company's performance in a key business segment.

The market's sharp reaction to this news underscores investors' sensitivity to analyst perspectives, especially in the volatile telehealth sector. As Teladoc continues to navigate the post-pandemic landscape, where demand for virtual health services is evolving, such analyst actions can significantly impact investor sentiment and stock performance.
