Abstract
Venugopal, R. Veeramani, C. Edalatpanah, S. A.The relative performance analysis and ranking of the financial ratios are highly important for optimal portfolio selection in the stock market. However, the financial relative performance evaluation of financial ratios is a highly complex and nonlinear system. The primary objective of this research is to use the fuzzy Decision-Making Trial and Evaluation Laboratory (DEMATEL) approach to assess the relative significance of financial ratios from two groups: Accounting-based financial measures (AFM) and economic value-based financial measures (EFM). In this regard, the data for one-year performance (June 2018–May 2019) of eight industries in the IT sector has been collected by distributing a questionnaire among two experts: investors in the NASDAQ exchange, and a professor in finance. Based on the collected information, AFM and EFM are ranked by using the fuzzy DEMATEL approach. Finally, fuzzy DEMATEL approach is compared with the classical DEMATEL approach. The empirical results assist the investor and traders to select among the selected stock.
