Full service agencies and discount agencies
One pays for what one gets. If one examines the historical trajectory of most of the stock exchange markets in the United states, one will verify that the fees for commissions where fixed: none of the stock exchange agencies were authorized to change less than minimum fixed for all the sector.
But, on May 1st 1975, the commission fees became negotiable, that is, the stock exchange agencies could charge a greater or lesser percentage on the commissions as permitted by the competition or benefit margins.
Under this negotiable fees regime, the agencies could change a greater or lesser percentage depending on the services given to the investor. In this sense, the stock exchange agencies are divided into two great groups: those of full services and those with discount services.
