Morgan Stanley rebalanced itself after the financial crisis from a trading house into a wealth management giant. Acquisitions of Smith Barney, E*TRADE and Eaton Vance built a franchise that manages trillions for households and institutions, producing fee income far steadier than markets revenue. The institutional securities arm remains a top-tier investment bank in advisory, underwriting and trading. That blend, roughly half durable fees and half cyclical Wall Street, defines the modern firm, founded in 1935 when Glass-Steagall split it from J.P. Morgan.
