Stocks in Europe received a mildly positive hangover from Asia-Pacific, where Chinese tech shares listed in Hong Kong bounced on Wednesday after 12 major companies signaled compliance with antitrust laws. Stateside, stocks rose to record levels as investors digested better-than-expected results from major U.S. banks including Goldman Sachs, JPMorgan Chase and Wells Fargo. Investors were tracking the latest vaccine developments Wednesday. U.S. health authorities on Tuesday recommended pausing the distribution of Johnson & Johnson's Covid-19 vaccine after six women under the age of 50 developed rare blood clots after getting the inoculation. Johnson & Johnson announced that it would delay the vaccine's rollout in Europe, while South Africa also suspended its use.
