While the OP is absolutely insane, I would say that I would not want FB on my portfolio as a long-term play. I'm not saying that I think FB will burn out in ten years - I realize by that time FB could be trading around Apple / Google levels. However, there certainly is the possibility that it will be nothing by then, and its risk I don't want on my portfolio. In addition, I'm having trouble trusting their revenue stream. Very hard to put an accurate number on as they aren't really selling a product, and the opportunity of manipulating the numbers is far higher than companies like Apple. I can easily see FB tanking earnings because of this one quarter and the stock dropping 10%. In addition, I think FB will be significantly overvalued (at least for the first 6 months or so) because first-time investors who don't know a thing will buy into the stock solely based on name recognition.
That being said, I think there is an opportunity to day trade this stock after the IPO. I could almost guarantee the stock will appreciate on Friday. WIll be interesting to see if it does like other tech IPOs and gains on day 1 but drops after that (look what happened to Yelp). Have a feeling FB will gain for longer than just their first day - again, going back to the first-time investors/name recognition argument.
