I got this idea last night and started to implement it. I had an idea that over the years, in my case since 2005, i bought shares in various companies with varying degrees of success, some losses, some fantastic gains. But then looking on the OST portfolio list, i see the % gains change if one makes additional acquisitions or sales, So i thought of making a list that has all the purchases and sales of every single share i ever bought, obviously adjusted in the case of a split, consolidation or other corporate action. but then one can see how it went... I also got an idea once i have compiled this list i want to create a chart of some sort that will overlay overall performance and individual purchases to see what really fueled growth in the portfolio or not. i dont really know how i will achieve this, but its my next task. I thought we should discuss this as maybe some others would find it interesting or already thought of something similar? whats your thoughts? btw: i have an idea in my head about how to achieve a very informative chart. but will see if it works before speaking too much about it :)
