Yp_1: So, in your opinion, everybody who only cares about SP, because he/she is not a fanboy, but a boring investor holding 800k shares (which is what I think the original poster holds) is an idiot?

Oh, I would never call anyone an idiot! But I'd say, everyone who only cares about the share price and otherwise ignores key facts about company, management, technologies, products, developments, markets, peers, perspectives, etc. etc. does not manage his investment optimally and might very well fall short of reality.
