Results of several researches in Iran clearly confirm the inefficiency of the TSE. In this inefficient market, investors seek to find high performance companies. But the key question is how high performance companies can be identified. Ranking of companies regards as one of the easiest approaches. In literature, there are various ranking approaches each with its own indicators. This paper is to provide the results of the comparative study on the Tehran Stock Exchange (TSE) companies' rankings based on accounting profitability ratios and the TSE's excellence indicators. Using correlation tests, we found a weak correlation between companies' rankings were calculated based on the accounting profitability ratios and the TSE rankings. This findings means that a highly ranked company by the TSE's ranking system may not be necessarily highly ranked based on accounting profitability ratios or vice versa.
