Accordingly, firstly financial performance of Borsa Istanbul (BIST) 30 index firms that both are and are not in XKURY has been evaluated in here. Different from previous studies, not only traditional performance measures (ROE, ROA, ROS, CF/TA) but also value-based performance measures (MVA, CFROI, CVA) are employed together in the performance evaluation. Thus, the financial performance of firms is evaluated by using TOPSIS method, which is one of the MCDM approaches, in the defined problem structure which considers multiple criteria.
