Brokerage Firm - Question 31

How can I be more knowledgeable about investing so I don’t need a broker?

Without being facetious, all you need to do is have as much knowledge, judgment, and up-to-date information as a competent full-time broker or adviser. In addition, you need to be willing and able to spend 40-50 hours weekly managing and monitoring your investments.

Obviously, if you're asking this question, you have reason to feel that the commissions you have paid in the past to a brokerage firm or broker have not been justly earned by that broker or firm.
