"Where do these idiots come from?" said the man in the mirror. When the only thing you can come up with to support this POS is the existence of a $15 billion ad market, but no direction on how Pandora can outshine the competition (let alone turn a profit), then perhaps you shouldn't be so quick to call others idiots.
BTW, here's something for you pumpers/longs to ponder: Pandora's advertising revenue was $375M for the fiscal year ended Jan 2013. If the total ad market is $15 Billion, that means that P managed to capture a whopping 2.5% of all available ad revenue. Seems to me that there are alot of other companies earning larger pieces of that $15 billion than P, and if you think 2.5% is respectable, you've got bigger issues.
What about all the direct and indirect competition for that market? Do you really think that it is still a strong buy? Are you accumulating or holding? What is your EOY PPS? I think it will be 6 or lower by Jan 2014. If you're in at 8 you should consider selling some or all before Fall IMO.
