He had a cattle position that went against him big time. I think he added and added to it, and ultimately was out 2 million bucks at one point. The day he was going to have to close the position because of margin requirements, prices started to reverse. They continued to move in his favor until he was actually able to get out with a small profit. The story goes that he left the floor, went to the nearest chapel, and on bent knees, wept.
This story reminds me of yours, except for the margin call thing. Adding to a losing position, hanging in there until one day you posted that you had made a big mistake, etc. Then CAT starts to turn and work its way back. Now you are in the green.
If it were me, I would be one thankful person, that's for sure.
