Nvidia Sinks on CEO Spy Scandal, Groupon Under Pressure, Trade Desk Soars

Today's biggest gainers and decliners in the stock market.

On this episode of Stock Movers:

• Nvidia (NVDA)'s Chief Executive Officer Jensen Huang’s affair with an alleged Chinese spy has sent the company’s stock plunging, become a focus of internal and government investigations, and is now threatening to reverberate across the AI industry. Nvidia shares slid 4.3% on Monday, erasing nearly $200 billion in market valuation, after Huang disclosed the romantic relationship Sunday in a memo to employees. The company’s board is assembling a committee of independent directors who will work with outside counsel to investigate reports of Huang being targeted for foreign intelligence.
• Groupon (GRPN) slumped in afterhours trading after it slashed its revenue forecast for the year and missed estimates for third quarter revenue. 
• Trade Desk (TTD) shares jump 23% in extended trading after the advertising technology company’s fourth-quarter revenue forecast exceeded the consensus estimate.
