I have traditional brokerage accounts at Merrill Lynch and Morgan Stanley. They are both the kind where you pay a small annual fee as well as a commmision for each trade.
However most of my friends have fiduciary accounts where they pay an annual fee based on the total amount in the account but no commissions.
The rational for the fiduciary account is that the broker makes more when you make more so they are your advocate. However since I am not a frequent trader what I pay between an annual fee and commissions is a fraction of what I would be paying if I had to pay an annual fee that was a percentage of the amount in my account. So what would be the advantage of paying much more because the broker makes more if I make more.
