Master Don Juan
Big IPOs will slow down the trading system with heavy volume. Fast moving markets like an IPO on the first day are about impossible to day trade without at least a direct access platform. Even a trade that is not intended to be a day trade can turn into one if it hits your stop loss within the first day. I have had people tell me they lost 10-20 full points waiting for their on-line broker to fill an order. A guy I knew had an Ameritrade account and we did an experiment trying to send a buy order when an ipo stock was screaming upward. He sent the ameritrade order, then bought shares off the Island ECN getting filled instantly, and then pulled up the Ameritrade screen to wait almost 15 minutes and 19 points later to get his fill, which was of course near the top of the run after the stock slowed down. That $5 Ameritrade commission cost him $1,900 in lost profit. (They did refund his $5 when he complained, lucky him.)
This example is an extreme one in a raging market, but that is not so uncommon with IPOs, especially on the first day. Even the direct access systems have problems with the immense volume at times. The day that UPS did its IPO, Island's quotes were off by 5-10 points at times. Trading an IPO on the first day is risky business, given extreme volatility and volume that can cause system problems. It's not that money can't be made, but you usually have to trade a smaller share size and plan ahead for larger slippage than normal.
