Loss aversion - hold onto losers (or add to losers)

fear of regret - hold onto winners too long - would hate to sell and then watch it keep ripping. Also hold onto losers too long - by selling you finally admit you made a bad choice. However at some point you will sell if you can blame it on something other than yourelf....particularly macro data like GDP or i rates.

Blame game is a way to reduce cognitive dissonance. Ties into defenses for bad forecasting. if-only, cet-parib, etc. All this stuff is so interconnected.
