In this paper, the fuzzy chance-constrained data envelopment analysis (FCCDEA) approach is presented for stock evaluation and portfolio selection under data ambiguity. To propose FCCDEA method, data envelopment analysis (DEA), possibilistic programming (PP), and chance-constrained programming (CCP) approaches are applied. It should be noted that FCCDEA models can be used by decision makers (DMs) under optimistic and pessimistic viewpoints. To show the applicability of the proposed fuzzy chance-constrained DEA approach, FCCDEA models based on possibility and necessity measures are implemented in a real-life case study from Tehran stock market. The results show the efficacy of the proposed FCCDEA approach for stock assessment in the presence of fuzzy data.
