Ignore the technical analysis crap. The reason you shouldn't buy GOOG is because it's already priced for perfection. With an 80+ P/E, there's very little room for positive surprises. They have to grow incredibly fast just to meet the expectations that are already priced in. If they only grow moderately quickly, the stock will drop.

That's not to say it can't go higher in the short term, just that there are better plays available right now where future expectations of growth aren't already factored in to the same degree.
