The Rank is a quantitative model based on trends in estimate revisions and EPS surprises. Stocks are ranked from 1 to 5, with 1 being the best rank ("strong buy") and 5 being the worst ("strong sell").

Is this all that is known about the Zacks ranking system? If the rules are not fully known it becomes somewhat of a black box from our standpoint.

I have previously mentioned Rabbitt Analytics, whose ranking rules are disclosed.

I have also raised the point that a Value Line T1 or T2 ranking could in and of itself introduce a bias which influences a stock's future performance. Unfortunately there is no way to prove or disprove this.
