[citation][nom]ta152h[/nom]Yes, because arbitrary cycles are really the key to buying stock, not the actual performance of the company in execution and technology. It's just automatic, 2015 will work, because AMD is doing good with "5s". Makes you wonder why they even bother with the other, unimportant stuff.[/citation]
Not saying that it's every 5 at all, but by the looks of their history, AMD will work on a large development plan for an extended length of time before it starts to pay off. They have done this multiple times in the past (look at their change in marketing, market share and the products they release during those periods and you'll have an idea of what i'm talking about).
The reason you CAN invest on the stock market and you CAN make money off it, is because business plans are there with the same goal and executed only slightly differently to each other in the same market sector. Heck, look at most share prices in the tech industry and you'll see the same pattern - money has to be invested before they get the rewards, thus the up and down.
