The Charles Schwab Corporation operates a diversified financial services business model centered around wealth management, securities brokerage, banking, asset management, custody, and financial advisory services. The company serves individual investors and independent investment advisors through two primary segments: Investor Services and Advisor Services. Schwab generates revenue primarily through net interest revenue (which accounts for roughly half of total net revenues, driven by client cash balances and bank lending), asset management and administration fees (including proprietary mutual funds and ETFs), and trading revenue from order flow and principal transactions. Geographically, Schwab operates predominantly in the United States, with a limited international presence in locations like the U.K., Hong Kong, and Puerto Rico. The firm holds a dominant competitive position as the largest publicly traded investment services firm in the U.S., bolstered by its 2020 acquisition of TD Ameritrade, which significantly expanded its scale and capabilities in the independent advisor custody market.
