The Goldman Sachs Group Inc. unit that executes share buybacks for clients just had its busiest week ever, but even that couldn’t keep stocks from flopping into a correction.
Last week, the firm’s corporate-trading desk saw 4.5 times its average daily volume from 2017, according to data seen by Bloomberg. Even as companies scooped up their own shares, the S&P 500 Index fell 5.2 percent, its worst weekly slide in two years.
