I'm thinking based on other posts about FB that banks might stop support the price soon enough. How can they handle all the possible lock up shares, billions, that will be flooding the market in the months to come? FB will be competing for dollars with many, still growing, much lower priced stocks like AAPL or GOOG? You can't really treat it like AMZ because it doesn't have a physical business model with income from sales + auction fees and not to mention cloud computing etc...

Based on the market reactions, the hype effect is wearing off pretty fast at this moment.
Joe public will continue to dribble money into FB at various price levels so there's no quick crash after the initial shocks (IPO, earnings, dilution, etc). Unlike other stocks, there's a dedicated crowd, even professionals, that are defending FB even beyond their pocket book. It's almost feel like a cult worshiping their idol so it will be interesting to see when they realize their messiah cannot take them to the promise land of $40+. Oh well, dreams will be broken but Wall Streets will go on. Next please.
Since the expectations have dropped quite a bit this early prior to earnings (to my surprise and dismay

). FB could be gapping up if the stock just manage to beat estimates by a fair amount of 20/30% and pretty much a non event if inline or it could plummet some more if earnings are disappointing. But the rally, if there's one, will be short lived as it will be sailing into a maelstrom of massive share dilution @ 90 & 180 day plus much more at the year mark.
FB even with low earnings can still scrape out decent income due to low operating costs and companies giving the ads a try. But as soon as the companies found out that the ads doesn't translate to $ (as very few clicked on them and let face it the FB crowd doesn't use FB to buy/research on products, there's eBay, Amazon, retail, + other venues and medias), than it's good bye and good night for many of them but this can take a year or two to play out.
