Stock brokers sell securities to the brokerage firm s clients.
The brokers are expected to find and sign up new clients, match various securities to clients needs, and develop an effective sales presentation for various securities. The broker s income is earned primarily through commissions generated by the sale. However, there is a very wide variation around this number, with many earning far less and many earning far more. For example, a brokerage firm may employ securities analysts who are experts on the health care industry, the forest products industry, the banking industry, the computer industry, etc. A portfolio manager selects and manages investments that meet the goals of the firm s clients.
