ok - this type of analysis would be useless... even if you get the right info... which is a big if.. how many thousands if not millions of people in the world are already doing this? what make you think you can do it better?.. there is no edge to be found there.
instead - pay attention to what stories they push - supplier problem? quality problem? sales forecast rumor up/down?
without fail they always push something around the earnings release... unfold that story... that's the feast dinner I always talk about.
Now - real fundamental research, may still be possible, if you are talking about a micro cap, and you actually fly to say the China plant and talk to the local guys and find out the truth.... there you may have an edge.
APPL? forget about it... how many analysts do you think have set up camp just to make sure they leave no stone unturned?... and if they find something, you think they are gonna publish it?
that's why, with a broad stroke of the brush, it is safer to take the opposite side of all the financial news, than taking the face value... because usually people release news for a purpose... and that purpose is definitely NOT to inform joe six-pack lol.
