Investors also were bullish on reopening plans - which will go all the better if there's a vaccine on the horizon.   Morgan Stanley biotechnology analyst Matthew Harrison has flagged six vaccines he thinks have a good chance of success. "We believe millions of doses could be available by fall 2020," he wrote, "assuming no delays." Oil has recovered handsomely from last month when futures contracts fell below $0, writes CNBC's Patti Domm. The soon-to-expire June contract for West Texas Intermediate settled at more than $31 a barrel on Monday.   The rebound is due in large part to producers cutting output, but also on growing demand as states reopen their economies.   "The focus moving forward will be on the opening of the economy," said Quincy Krosby, chief market strategist at Prudential Financial. "How quickly can it be done and how safely can it be done."   Subscribe to CNBC PRO for exclusive insights and analysis, and live business day programming from around the world.
