So I'm sure we've all read about the eager American investors who want one of the world's most entangled companies split into bits and pieces. This is a company that has music, and leverages it's record sales division for internet radio companies (ex: the upcoming iRadio), in order to sign new deals, then mixes it's music into it's cobranded work with companies like Square Enix to produce television series (ex: Sony Music did work on Durarara, later released two PSP games apropos).
Essentially this is short and sweet, if you like SNE, you want them together, not apart, that would only provide a little dough in your pockets short term as you sell off your shares and watch Sony fall into dissarray - KEEP SNE TOGETHER. NO PRESSURE.
Disclosure: I have no positions in any stocks mentioned, but may initiate a long position in SNE over the next 72 hours.
Additional disclosure: Sony makes music, games, consumer and medical technology, it is a company that relies heavily upon resourcing it's intertwined divisions across the company as a whole.
