J.C. Penney Company, Inc. (JCP), Microsoft Corporation (MSFT), Research In Motion Ltd (BBRY) and This Week’s Five Dumbest Stock Moves

Keep in mind that these are registrations. These aren’t necessarily people actively on the site. Pandora Media Inc (NYSE:P) reported 69.5 million users logging into the service last month. That’s not too shabby, but obviously it’s not 200 million.

However, if Pandora throws us a big number, it makes itself available to be bludgeoned by the same sum.

If 200 million registrations is impressive, consider that Pandora cranked out just $51.9 million in subscription revenue last year. That breaks down to just $0.26 per account over all of 2012. There are too many freeloaders at Pandora, and this seemingly flattering milestone isn’t very flattering to the service’s model.

5. In security
Shares of Fortinet Inc (NASDAQ:FTNT) tumbled 13% on Thursday after the company issued problematic guidance.

The network security provider sees a first-quarter profit of $0.10 a share on $134 million to $136 million in revenue. The refreshed guidance falls short of where Wall Street’s perched, as analysts were targeting net income of $0.12 a share with more than $140 million on the top line.

At a time when companies are showing signs of life and network breaches continue to dominate the news, investors certainly weren’t expecting bad news out of Fortinet Inc (NASDAQ:FTNT), especially since it had easily surpassed market expectations in its prior quarter.
