Shares Hit New Highs

All the shares I sold are now at much higher price.  But I am not so concern as I just want to get out.  However, my wife feels sad we missed out in some opportunity to lessen our loss.  However, I strongly believe the price will drop and when it drop, there is no time for investors like me to get out.  I am very slow in responding the changes in market.  This is why I keep losing money in stocks.
