• abstract = "Stock valuation is very important for fundamental investors to select undervalue stocks to earn excess profit. However, it may be difficult to use stock valuation results because different models generate different estimates on the same stock. This suggests that the value of a stock should be multi-valued rather than single-valued. We therefore develop a multi-valued stock valuation model based on fuzzy genetic programming. In our fuzzy GP model, the value of a stock is represented as a fuzzy expression tree whose terminal nodes are allowed to be fuzzy numbers. There is little literature available on the crossover operator for our fuzzy trees except the vanilla subtree crossover. This study generalizes the subtree crossover to design a new crossover operator for the fuzzy trees. Since the stock value is estimated by a fuzzy expression tree which calculates to a fuzzy number, the stock value becomes multi-valued. In addition, the resulting fuzzy stock value induces a natural trading strategy which can readily be executed and evaluated. Experimental results indicate that the FuzzyTree crossover is more effective than subtree crossover in terms of expression tree complexity and run time. Second, shorter training periods produce better ROI. It indicates long-term financial statement may distort the intrinsic value of a stock. Finally, the return of multi-valued fuzzy trading strategy is better than that of single-valued and Buy-and-Hold strategy. We suggest that more attention should be put on the multi-valued stock valuation approach.",
