Aug. 3 (Bloomberg) — Bloomberg’s Dawn Kopecki discusses the performance of JPMorgan Chase & Co.’s commodities unit. Blythe Masters, the head of the unit, sought to reassure her team on an internal conference call on July 22 after "extremely difficult" dismissals, defections and a first half in which some results were as much as 20 percent below expectations. Kopecki talks with Erik Schatzker on Bloomberg Television’s "InsideTrack." (Source: Bloomberg)
