In my latest blog post, I tried to quantify the effectiveness of the fundamental ranking system, T-Rank 2.0. The effectiveness is defines as the relationship between the rank of a stock and it's 1 week return. For details please go to my blog at http://trustamind.blogspot.com/. But everything important is included in the chart below.
The x axis is the rank (from 0 to 100), the y axis is the annualized weekly return.
Basically the chart says if an investor moves up 10 rank point, the average gain on his annualized return is about 1.7%. But the further he pushes up, the better it gets. If he moves from 90 to 100, his annualized return should improve 3.6%.
