Morgan Stanley Day

Morgan Stanley traces its roots to J.P. Morgan & Co. Following the Glass–Steagall Act, it was no longer possible for a corporation to have investment banking and commercial banking businesses under a single holding entity. J.P. Morgan & Co. chose the commercial banking business over the investment banking business. As a result, some of the employees of J.P. Morgan & Co., most notably Henry S. Morgan and Harold Stanley, left J.P. Morgan & Co. and joined others from the Drexel partners to form Morgan Stanley. The firm formally opened the doors for business on September 16, 1935, at 2 Wall Street, New York City, just down the street from J.P Morgan. The firm was involved with the distribution of 1938 US$100 million of debentures for the United States Steel Corporation as the lead underwriter.

Today Morgan Stanley is an American multinational investment bank and financial services company headquartered at 1585 Broadway in Midtown Manhattan, New York City. With offices in more than 42 countries and more than 68,097 (2020) employees, the firm's clients include corporations, governments, institutions, and individuals.

Institutional Securities has been the most profitable business segment for Morgan Stanley in recent times. This business segment provides institutions with services such as capital raising and financial advisory services.
