The social media bubble that had been building up for the last five to six years might have actually burst. Aswath Damodaran, Professor of Finance at New York's Stern School of Business, and one of the world’s topmost experts on valuation, says Facebook IPO "might be actually the trigger for the end of momentum game" for social media companies. "I wouldn't be surprised if this is a dampener for new social media IPOs," Damodaran told VCCircle in an exclusive interview last week. The finance guru was in Mumbai for a two day training programme on corporate valuations organised by VCCircle's training arm.
