Value Defined
Modern portfolio investment theory is based on the premise of efficient markets.  It purports that efficient markets will be effective in collectively processing all available information on a stock to arrive at an appropriate price.  The available information includes a variety of business risk factors in addition to financial statement data.  These risk factors are related to all components of the business including management, organization structure, products, markets, legal issues, production capabilities, employee relations, and foreign exposure.  The value investor will seek to use financial statement data to arrive at a fair market value based on his or her assessment of future earnings and a risk adjusted discount factor.  The value investor seeks to make a case that the market price may be to low due to underestimation of future earnings or overestimation of the business risk factors.  If the analysis is correct, then the stock price should adjust to a higher price over time as markets digest the prospect of higher earnings or lowered risk.
