Global markets had soared at the beginning of the week after U.S.-based biotechnology company Moderna announced that initial tests for a possible coronavirus vaccine produced favorable results from a small sample of people.
The markets floundered Tuesday when a report on the medical news site Stat said there was not enough data to assess the vaccine's potential effectiveness. The Dow Jones, S&P 500 and Nasdaq all finished Tuesday trading sessions with losses, as did most European markets.
