“…stock β s and volatilities) as inputs, and EPS and returns as outputs. Chen (2008) uses average equity, average asset, and sales cost as inputs, and revenues, operating profit and net income as outputs, while Kadoya et al (2008) employ surprise indices (calculated based on differences between realized figures and consensus forecasts of earnings, sales, etc.) as inputs, and historical returns over various time horizons as outputs to benefit from the mean‐reversion anomaly.…”

“…Recently, some scholars have examined also the efficiency of multicriteria methodologies in which portfolios being compared are formed on the basis of composite value measures that combine two or more individual valuation criteria into a single summary metrics of relative value. Moreover, some recent studies have employed data envelopment analysis (DEA) in portfolio formation (Chen, 2008; Kadoya et al , 2008). The basic idea of the DEA approach is to divide the stocks into portfolios based on their efficiency scores using a mathematical programming technique.…”

“…DEA [14] is a multicriteria evaluation method that can screen the most desirable alternatives (i.e., decision-making units (DMUs), e.g., firms) among large sets by means of mathematical programming. DEA provides for each DMU a composite score, which is referred to as efficiency using actual input-output data for a sample of them and this facilitates the complexity of analysis by evaluating the multicriteria [15]. DEA can be employed in a multiple input-multiple output setting and, in regard to model building, it avoids the prior assumption on weights of inputs and outputs; the weights are produced by the optimization process.…”

“…Th e results of this study show the trend of signifi cant relationships between three fi nancial variables and the effi ciency results of enterprises. In addition, Kadoya et al (2008) identifi ed investment strategies by using the DEA and mentioned that the book value of companies was a classic criterion of effi ciency evaluation. It helps investors to know the trends of the market value and the performance of companies.…”
