Most of us are well acquainted with the stellar track-records of the legendary Mr Buffet and Mr Soros. Very little, however, has been heard of the exploits of the less famous Mr Leon. This journal aims to correct the imbalance. It will be a real-time record of trades based on his investigations of discrepancies in the prices of quoted shares. The journal will run for six months starting from the 1st of August, 2006.
