摘要：This paper presents a study to investigate the effect of world’s financial turmoil on performance of petrochemical firms listed on Tehran Stock Exchange (TSE). The study designs a questionnaire in Likert scale and distributes it among 87 selected people from 250 existing experts who were active in TSE. The study considers four groups of questions associated with liquidity ratios, operating ratios, leverage and profitability ratios. The questions consider whether financial turmoil has influenced on these four groups of financial ratios or not and the results have been verified using t-student test. According to our survey, although financial turmoil does not seem to have any important impact on operating ratios in this sector, the chaos has influenced on other three financial ratios including liquidity, leverage and profitability ratios.
