Right and Wrong on Short Positions

This week the S&P 500 reached its new high. However I decided to exercise short positions. I put three short positions on P&G, JetBlue, and TD Ameritrade. My predictions for JetBlue and TD Ameritrade were correct, because I have pessimistic views about their future earnings. But what I thought was wrong on P&G. Luckily I have loss less then $1,000 in my account.
