It is very important to understand the difference between a broker and a stock market analyst. An analyst literally analyzes the stock market, and predicts what it will or will not do, or how specific stocks will perform. A stock broker is only there to follow your instructions to either buy or sell stock… not to analyze stocks.

In most cases, brokers earn their money from commissions on sales. When you instruct your broker to buy or sell a stock, they earn a set percentage of the transaction. Many brokers charge a flat 'per transaction' fee.

There are two types of brokers: Full service brokers and discount brokers. A full service broker can usually offer more types of investments, may provide you with investment advice, and is usually paid in commissions.

Discount brokers typically do not offer any advice and do no research - they just do as you ask them to do, without all of the bells and whistles.

So, the biggest decision you must make when it come to brokers is whether you want a full service broker or a discount broker.

If you are new to investing, you may need to go with a full service broker to ensure that you are making wise investments. They can offer you the skill that you lack at this point. However, if you are already knowledgeable about the stock market, all you really need is a discount broker to make your trades for you.

Many people who trade purely over the internet will often use the services of a discount broker.
