I have not done any research into the VISA IPO. However, my theory is that VISA will trade in similiar fashion to the Nymex IPO or the Blackstone IPO. There will be a lot of hype the days before that VISA is going to be the next 5-bagger like Mastercard. On the first day of trade its going to open real high just like the Nymex and then there will be a wave of selling pushing it down as hedge funds flip the IPO like a Florida condo in 2005. Over the next weeks or months, the stock will go nowhere and then suddenly dive just like NMX. Then Mastercard will also take a hit as the market isnt big enough for two credit card stocks. I dunno just a guess, but thats how I think it will trade...
