stop losses, page-9

Moped.
Just a thought on your strategey.
Would you agree to some extent that what you are actually implying is to cut off your profits and letting your losses run ?
Not trying to be funny here, just interested if you considered that!
How do you decide to take profit/sell?
How do you decide where the bottom is when you buy?
Granted that stocks in the top 50 are far more predictable and thus less risky but surely if one turns bad , there must be a point where an exit is warranted ?
