Ok here's a sample. I shorted ERTS near the close today on the buyout rumors hype as I think the buyout rumors are over-done and don't make sense.
A Fast Money contributor goosed the stock in the final hour on CNBC by saying he thinks ERTS is going up on a MSFT take-out rumor. Also there was post on a Variety.com blog that Disney may buy ERTS. These rumors are a dime a dozen, and the stock going up 11% on them is pretty ridiculous in my opinion.
Microsoft is silly because they got indigestion on their last 2 big videogame acquisitions. 1) Rare, maker of GoldenEye, and PerfectDark, has been a total disaster. Viva Pinata? Please... 2) Bungie has been a financial success with Halo, but the studio was spun out because they threatened to quit and didn't like working for Microsoft. And now you want to spend $8 billion when your biggest studio just said we hate you and left? Moreover the biggest value in ERTS is their multiplatform sports games, which wouldn't be worth much to Microsoft if they went exclusive to Xbox 360.
Disney is better off buying THQ for its development talent as it is much cheaper that spending $8B or so on ERTS. ERTS you get a sports monopoly, which doesn't help their strategy of pushing their kids/movie properties. Plus you're not spending $8B to get disappointing Maxis Spore, Dead Space, and Mirror's Edge type franchises.
My cost on the short is $18.50. I posted this on my twitter id intra-day too, so don't whine that I don't post what I do. I figure even if ERTS gets bought later this year, if it doesn't happen in the next day or so, the stock will sell off after this hyped advance today. So the risk/reward is pretty good in my opinion to short it on the hype.
