I wouldnt buy the IPO for one reason. Look at all the other online brokerage stocks. None of them appear to be doing well and ALL of have issued bearish guidance. If there are so many bears out there about online brokers, then who will buy the stock? Now you might see news releases of the IPO being "oversubscribed", but its all hype. Nothing but hype. I bet it drops a few points or more before its a buy.
You are buying a global market maker with connections to over 60 exchanges. The retail brokerage business is a small portion of the company. Read the prospectus before posting so you at least sound smart.
But is marketmaking all that great a business? Won't they get hurt by penny options? I'm not stating an opinion, just asking.
Are you kidding? IB is pioneering penny options, they offer a special penny option quotation system, even for ones not supported by exchanges.
