Gilead Sciences Inc. shares were whipsawed for the second time in a week after a summary of a Chinese trial of its Covid-19 drug appeared to show that it was a failure.

The synopsis, which the company and a scientist working on the trial said didn’t fairly represent the actual results, saw Gilead’s shares closed down 4.3% to $77.78 on Thursday in New York. The broader market fell as well, with the S&P 500 ending down 0.05%.
