The primary principle of the method is to match decision-makers’ preferences with stock characteristics. The model requires that a number of potential stocks have been proposed. Alternatives are then evaluated and compared under various factors. It allows investor to incorporate personal preference and judgement in the solution process. An example of evaluating eight listed companies in the steel industry of China is showed to illustrate the solution process, the results of which are promising.Key words: Stock Investment Decision; Judgment Matrix; AHP; Grey Relational Analysis
