Again --- someone asked about how "I" know when to sell a stock...
Mostly what we've talked about is how to BUY - and why to buy - but it is just as important to know when to SELL...
I stumbled upon this fairly well written "opinion article" about how one fund manager makes this critical decisions... and it mirrors most of my thinking.
When the position is too big (has grown) - or when there is a fundamental change - good or bad... or sometimes when you were just "wrong" about how you thought the stock would act.
