Co-efficient to measure Value in the stock market;

I CANNOT FIND a news entry for THE NAME OF THE CO-EFFICIENT that measures value in the stock market. I think that it should take into consideration the five following factors. Others may be needed, and these may be redundant. 1. Gross Domestic Product 2. Gross National Product 3. Interest Rates 4. Tax Rate 5. Reserve Ratio Anyone who knows how to calculate it could use these to begin the work. *NOTE: Item six in letter to Kerry Campaign of 2004 suggested this.
