ranking of companies listed on the exchange represent their status and considered a criterion for investment. also, it increases market's competition, development and efficiency. in this study, the fifty superior companies listed in tehran stock exchange were ranked based on financial ratios (liquidity, operational, leverage and profitability) using fahp- ftopsis hybrid approach during the...

abstract this study aims at profitability prediction of listed companies in tehran stocks exchange (tse), using artificial neural network. the respected sample consists of 90 firms from 2002  to 2009 (720 firm/years). attention to the framework of study reduced the number of 720 firm/years to 630 firm/years. these firms separated in two groups of learning sample (540 firm/years) and test sample...
