Prudent,
The reason why a hedge fund with $1 million under management would want to use a prime broker is because the prime broker
can get you clients. This is the main reason why hedge funds use prime brokers. A firm such as Bear Stearns or Goldman will sell itself by saying that it can get you hedge fund clients. Since i-banks have a private client division, they will know plenty of wealthy investors. Of course, in exchange for referring clients, they expect you to trade through them even though their commission rates are not cheap. The hedge fund benefits not only from any clients that are the introduced by the broker, but also from the air of legitimacy that an investment bank can give. Clients think that if you clear through Bear Stearns, you are less likely to cheat them. There was a Forbes article a few years back titled "Bear Stearns and Bucket Shops" that mentions this.
Is this best for the client? Of course not, since the client ends up paying higher commissions. But many clients don't understand this.
Is this good for the hedge fund? In many cases, yes. It is not
easy to raise money, even with good performance. One way is to use a 3rd party marketer, who will charge anywhere from 20%-50% of the fees collected. The other way (the cheaper way) is to
trade commissions in exchange for clients. This way, the money is coming out of the pockets of the clients, not the hedge fund owner(s).
Ideally, a hedge fund would get clients based solely on its outstanding performance, while getting the best commission deal possible for its clients. Since the performance is great, money would be pouring in, and there would be no need to charge the clients a higher commission rate in exchange for finding the clients. Ideally, the fact that the hedge fund was looking out for its clients by getting a great commission deal would be sufficient marketing. Of course, we don't live in an ideal world, do we?
