Finance professors and experts on internet IPO's, Ritter at the University of Florida and Aggarwal, are skeptical that average investors would make money on the Facebook IPO. Ritter's information base shows that from 1980 to 2009, the average IPO's would jump 18% on the first day and 21% in the next three years, showing that hype and marketing with restricted supply of shares relative to demand created can artificially increase the price on the first day. As average investors get to invest after the opening day and on less favorable terms than the insiders and bankers doing the IPO, its not such a good deal for the average investor. Google performed well for the average investor, but this could be the exception rather than the rule. Google operates in a space, namely "search" engine, that is an essential part of the functioning of the internet space, which accounts for its continued growth. This may not be true for game firms such as Zynga, group discount sites such as Groupon, and social network sites such as Facebook, because their growth could stall suddenly. As Jason Zweig points out in the Journal, another factor is the starting price. At a high enough starting price the risk for investors could be high and returns may be no higher than the average 6-7% range....
