Market Turmoil as UnitedHealth Crashes

In a dramatic turn of events, the Dow Jones Industrial Average plummeted over 600 points during Thursday's premarket trading, largely due to a staggering 20% drop in UnitedHealth Group's stock. This marks the health giant's worst trading day since 1998, following its first quarterly earnings miss in years and a downward revision of its full-year outlook.

Broader Market Impact

While the Dow suffered, the Nasdaq 100 and S&P 500 showed resilience, gaining 0.73% and 0.50%, respectively, by 7:42 am ET. This divergence highlights the selective impact of UnitedHealth's woes on the broader market.
