Subject: Re: Broker recommendations?
Anyone can correct me if I'm wrong but if you have a margin account the broker can loan your shares and profit from that.

I think you are right but I can’t think why that should bother a client. And sorry for the IB boosterism, but some brokers like IB actually share the borrow fee with the client who is lending the shares.

This is another example of IB’s basic philosophy, à la Costco, of charging clients based on the cost of their services plus a small profit, rather than taking advantage of them with hidden charges while making some things (like commissions) free.
