Healthcare stocks driving U.S. market after Biden's Super Tuesday successes

The U.S. stock market rally Wednesday is very much driven by huge gains in large healthcare insurers, as Joe Biden had an impressive showing on Super Tuesday. The S&P 500 rose as much as 1.76%, with all three major U.S, indexes up considerably as well. importantly, the rally still wasn’t completely risk on, as the 10-year treasury yield continued falling, remaining a touch below 1%, although still with a positive spread over the 3 month’s yield of 0.81%.
