we have steve mill lon vich coming out questioning whether apple will continue to have the innovation necessary and the geographic expansion necessary to support the growth rates that are baked into the stock. >> it's not just an issue of growth rates either. it's an issue of margins. if they continue to innovate, they charge a premium for the product. that's a lot of the fundamental case for the stock here. i don't know it was just tax related because a lot of institutions might have been less concerned about taxes early on. if you own a big position and it rises at some point, you're going to see yourself pairing back. then you get tax issues, then momentum and you get questions and those things start to cascade. that's what created a disconnect between a stock that otherwise would look cheap and why people are still selling it. >> also we talked about margins a few months ago, particularly with the ipad mini. people were worried about the margins in the ipad mini not being everything they were in other products. we also have to be worried about momentum. the momentum is clearly low
