About this page

This page shows the value of Kabutaro's stock portfolio at the end of each month. His total deposits are 6 million JPY, and the values since December 2013 are tracked against that amount. He started investing in June 2007, but until November 2013 he admits his approach was too casual to keep records, so there is no data for that period.
