European stock markets rebounded slightly Tuesday from the previous session's sharp falls triggered by escalating virus fears.Asian stock markets retreated however, with investors catching up with Monday's slide across Europe, and the Dow Jones index also slipped as trading got underway in New York.The dollar rose however after US lawmakers, as expected, agreed on a massive financial stimulus package.The pound and oil prices, which slumped Monday on UK virus and Brexit fears, retreated once more but their losses were less pronounced."Fears in relation to the new strain of the coronavirus have faded a little and so have some of the concerns that the UK could suffer a prolonged period of isolation," noted David Madden, analyst at CMC Markets.
