Subsequent to the adoption of the Capital Asset Pricing Model (CAPM), various modifications have been implemented. The incorporation of variables such as financial risks, liquidity, adverse factors, unforeseen events, and economic and operational elements has augmented the model's efficacy. As a result of these developments, new models have emerged based on the standard CAPM. Examples include the Revised Capital Asset Pricing Model, proposed in 2009 by Iranian researchers Dr. Rahnama-ye Roodpashti and Dr. Amirhosseini. This model demonstrates greater capability in interpreting capital assets by accounting for market conditions, the prevailing state of economic units, and investment portfolios. In this study, given the importance of applying these models for financial managers, economic analysts, and investors, we introduce and critically examine each of these models.
