With Facebook having finally announced plans for its long anticipated IPO this spring, speculation is already rife about the social network’s likely gigantic valuation and how the shares will go on to perform. For investors with anything short of many millions of dollars to invest, the circus surrounding what is expected to be the largest ever tech IPO will be one to watch rather than partake in.

For investors thinking of buying shares in the aftermarket, of course, that means the Facebook IPO should be treated with extreme caution.

More generally, though, the research suggests that flotations of all sizes should carry a health warning and Facebook is no different, notwithstanding the frenzy of media attention and noise…
