One example applicable right now, if you bought today at the low in the 70s, you could be near doubling up right now since it appears to be shooting up again, and now halted at 137.What makes you think you wouldn't have sold sometime before January 28? You could have sold earlier when it was $200. Then it would have shot up to $460 and you would be lamenting about the potential money had you waited an extra day or two. I definitely feel what you're saying, but hindsight is 20/20.
