"Goldman Sachs' US$2 billion deal for Facebook, valuing the social networking site at $50 billion, combines the worst elements of the 1997-2000 and 2004-07 bubbles.
It sets a grossly excessive valuation on an Internet company with modest revenues and prospects. It also involves an investment bank structuring a complex deal to maximize its own fees, while driving a truck through two major elements of financial services regulation.
Add a third element, that it places a company controlling personal information on 500 million users in close business partnership
with a Russian billionaire with a criminal record and you can see the deal is truly groundbreaking. It should also raise important red flags about current market conditions."
