I made this move a while back based soley on my gains and best guess. You have to admit, either way, it is a roll of the dice AT BEST. Taking profits, large and small is how I have made net gains. I am also not afraid of losses when I judge that what remains might do better elsewhere. Still lots of game here for me.
For me; To have a nice gain and hold simply because "what if they hit a solo homer?" is not a stategy that has been successful for me, usually I missed opportunities for gains.
