Pandora fizzles in day one

PANDORA BOXED: After a sizzling start (see items below), Pandora shares finished up a paltry 9% in their debut yesterday. By comparison, LinkedIn's shares rose more than 100% in day one of trading last month. Pandora stock traded as high as $26 before closing at $17.42. "In many ways it's a sign of sanity," Espen Robak of Pluris Valuation Advisors told the N.Y. Post, adding that at a $2.6 billion valuation "it's a pretty expensive stock." But Internet vet David Pakman took the long view, predicting, "It is the future of traditional radio, an amazing brand and unstoppable in that space." (6/16a)
