PRIMECAP Management Company was founded in September 1983 in Pasadena, California, as an independent investment management company. It is a California corporation registered with the Securities and Exchange Commission as an investment adviser under the Investment Advisers Act of 1940.
The firm's goal is to provide superior long-term investment results and to satisfy the specific requirements and objectives of its clients. Because we are stock pickers, not marketers, the firm has limited the number of clients it serves to 25, enabling its principals to focus on investment management rather than marketing.
The firm is a small organization by design and was founded with efficiency in mind to minimize the administrative burdens and bureaucracy associated with larger organizations. We recognize that our core competency is investment management, not administration.
PRIMECAP Management Company manages only equity portfolios for a select group of employee benefit plans, endowments, foundations, the Vanguard Group, and the PRIMECAP Odyssey Funds. The company's five principal portfolio managers have an average of 30 years of investment management experience. This depth of experience adds a historical perspective to our investment ideas.
Managing investment portfolios is PRIMECAP's only business. The firm is dedicated to a single purpose: to provide superior long-term equity returns to a limited number of large institutional clients.
