JEF vs FMS Comparison

Jefferies Financial Group is a full-service investment banking and capital markets firm that was founded in 1962. After nearly 30 years of focusing on institutional trading services, it entered the investment banking industry in the early 1990s, which ultimately grew into the core business. In 2013, Jefferies merged with Leucadia, a manufacturing-focused holding company. Since the merger, Jefferies became the core of the combined business as the bulk of the legacy portfolio was sold off and the parent company was renamed to match the subsidiary. Within the investment banking landscape, Jefferies predominately serves the North American middle market and has captured considerable market share over the past decade.
