MSCI’s world stocks index rose 0.25% to within touching distance of the record highs it had set on Tuesday. The index is up 14% this year and nearly 70% from its March lows, boosted by trillions of dollars in global economic stimulus and expectations that coronavirus vaccines will re-open locked-down economies.
