Well, the fact that Apple is so large actually serves my point: there is a lot of information on Apple. The information asymmetry between hobbyists and analysts is nil for Apple.

In fact, I'd argue the information asymmetry tilts in favor of individuals, considering that analysts publish their forecast. I wouldn't be shocked if these guys use "analyst expectations" as an input.

Anyway, this is bad news for the analyst, because the one resource they don't have is time to focus on one company. Hobbyists, however, can focus on Apple all they want. So I'm not surprised that Apple fans nail their earnings forecast.
