Or discipline?That is probably the most difficult thing to do in the market especially after doing research on a stock, it goes the other way than expected. It’s all about the ego.
10% is random but I see your point.

This was a topic discussed on the compound recently, and it was along the lines of, if you buy a stock, it should be one you are willing to add to if it drops 10%. Batnik bought HD with this in mind.
I'm not asserting a position here in either direction, I just know I've bought some stocks, they drop, sometimes I add, they continue to suck, and two years later I'm owning Disney down 20%.
