Alphabet Rises, Las Vegas Sands Climbs, UnitedHealth Falls on DOJ Medicare Probe News

On this episode of Stock Movers:
- Alphabet (GOOGL) shares rise after the company said demand for artificial intelligence products boosted quarterly sales, and now requires an extreme increase in capital spending — heightening pressure on the company to justify the cost of keeping up in the AI race.
- Las Vegas Sands (LVS) shares climb after the casino and resorts operator reported adjusted earnings per share for the second quarter that beat the average analyst estimate. Analysts attribute the beat to a solid performance in Singapore offsetting weakness in Macau.
- UnitedHealth (UNH) shares fall. UnitedHealth is responding to criminal and civil requests from the US Department of Justice about its Medicare practices, the company said, and has "full confidence" in its practices.
