The Dow Jones Industrial Average achieved an all-time high on Thursday, with a significant increase of 700 points, supported by UnitedHealth and financial sector stocks. In contrast, the Nasdaq Composite experienced a decline, primarily due to a selloff in chip stocks following disappointing earnings results from Broadcom. Broadcom's stock dropped 15%, and Ciena also fell below a crucial support level. The broader S&P 500 also saw an increase. Broadcom's performance appears to have created a divergence in market performance, with industrial and financial sectors showing strength while technology and semiconductor stocks faced pressure.
