It is obvious that the performance of a stock last year or last month is no reason, per se, to either own it or to not own it now. It is obvious that an inability to "get even" in a security that has declined is of no importance. It is obvious that the inner warm glow that results from having held a winner last year is of no importance in making a decision as to whether it belongs in an optimum portfolio this year.
Warren BuffettI'm sitting with six and a half billion dollars we're going to use to close the Mars-Wrigley deal on October 6. I've got to hand over that six and a half billion on October 6. Now, I have to be very careful about who I leave it in between now and then, because they're expecting that he show up.
Warren BuffettCredit worthiness is like virginity, it can be preserved but not restored very easily, so it is crazy to play around with it.
