CSX Corp (CSX) closed down more than -4% after announcing that Jamie Boychuk, executive vice president of operations, is leaving the company, and a search for a successor is ongoing. Stocks on Friday initially moved higher after a smaller-than-expected increase in U.S. Jul nonfarm payrolls knocked T-note yields lower. Stocks then extended their gains mid-morning as T-note yields fell even further on dovish comments from Atlanta Fed President Bostic, who said there is no need to raise interest rates further to ease inflation.
