This is a FYI from Bernard Baruch---it is in his book on investing---
He started investing and after 8 years he found that his entire portfolio was in the RED---not one single investment was green---
He took stock of his method of investing and discovered why he had all losers----
He was selling his winners ---or ,,, taking his profits and then reinvesting------but, he discovered that three things are manifest after the selection---#1 it could down 2 it could go up 3 it could stay the same.
When it went up he sold,, when it went down he held on until it went up and then sold for a profit--- if it stayed the same he held until it went up and then sold---NOTHING WRONG IN TAKING A PROFIT,,,RIGHT!!!
This philosophy could not be successful over time----
He then sold his losers immediately and kept his winners using a trailing stop ------Long term, this made him millions and he wrote books and managed money for others ---
Cheers--
