Past Performance Update

I recently updated my past performance page.

  tech-update (1)

When I first started filling it in this past January, I knew that one of the stocks I had taken a hit on had only been a half sized position. I never would have bought a full size of GEVO. But I let it go and figured it was par for the course and would probably all come out in the wash in the end. I did not want to make the loss only half because I considered that this would look devious, so I let it go.

As the months progressed, however, those half sized positions that I sold when they had huge gains started to go beyond the size of losses I had in other half sized positions. As such, the performance started to skew in my favor. The point of providing performance is to be transparent and I didn't want to be the guy who pretends to be transparent but really isn't. On the other hand, I now understand why other trading sites don't often provide performance. It's hard to do save for showing one's actual portfolio and that plays on privacy.

At this point, I have decided to add position sizes to my past performance as well as my trade alerts to members. This has brought my overall performance down but still gives a good indication of my results which are acceptable to me. 

On an other note, I also discovered that my short trades were showing as losses when they were gains and gains when they were losses, so the whole thing was screwed up. It is fixed now.

The Past Performance Page is not perfect. I have come to realize that it is impossible to make it perfect but I will do my best to keep it as accurate as I can going forward. Position sizes will never be perfect as my real portfolio size is continually changing and I round off the number of shares. Also I enter numbers so fast in multiple locations that it is easy to make a mistake. None the less, I have decided that a basic idea of my work and its performance is better than nothing.

So there it is. I hope you all agree.
