A stop loss

Our investment did well. It went from $6.00 to $8.00 to $12. 00. We were so excited. We hadn't lost the whole investment. Remember, many people coming out of the hi-tech boom did. Then, one day the market was very volatile. Our shares dropped several dollars. Someone - I think it was me - suggested that we put a stop loss on it. We did- at $9.00. The market continued to be very volatile. The shares dropped again and were sold at $9.00. We decided we wouldn't be greedy and accept, gratefully, all the gains- be what they may. However, it did hurt when we watched the stock rebound and climb to $24.00. It didn't remain there and today I can not find it on the TSX.
