I try my best to analise the financial big wigs reasons to down grade or upgrade a particular stock I own.
I always try to understand both the pumpers and dumpers reasons for their reports.
As you all know there are many conflicting reports on the same day.
Once I have gone through the chaff (military term) you need to make a move.
Do I buy more or do I sell?
It's a make or break decision.
Myself, If I have done my DD I then do what my gut tells me to do.
Three out of five times my gut instinct is correct.
