The spread of the more contagious delta variant of COVID-19 has become a worry spot for investors and policymakers. The Centers for Disease Control has said an estimated 83% of cases in the U.S. are tied to the delta variant of the virus. While tens of millions of Americans have gotten vaccinated, there remains a significant percentage of Americans who are either reluctant or outright hostile to the idea of being vaccinated.

Barely a week ago, the 10-year note was trading at a yield of 1.33%.

Wall Street is also in the midst of earnings reporting season. IBM rose 1% after the company reported better than expected revenue and profits, helped by its cloud computing business. Hospital operator HCA Healthcare jumped 14% after handily beating Wall Street’s second-quarter profit and revenue forecasts.

Outside of earnings, drug distributors made some big moves following reports that they are on the verge of $26 billion settlement over opioid lawsuits. AmerisourceBergen rose 3.7% and McKesson rose 2.9%.
