One of the most significant aspects to consider when discussing investing is the anomaly of returns and asset portfolios. In this method, the return more than the expected return and higher than the risk premium is regarded as part of the portfolio components, and the correlation of the portfolio components is studied so that an optimum portfolio can be built. Oil price shocks have been investigated in the current study on the emergence of asset portfolio anomalies in the oil industry from 2012 to 2022. The findings of the study indicate that both oil price shock and risk have an adverse and significant relationship with portfolio anomaly returns. According to the findings, while oil shocks might have a negative impact on the stock market owing to the uncertainty they cause in financial markets, this issue is dependent on the form of the shock (demand side or supply side). If the shock is on the demand side, the market may respond positively; if the shock is on the supply side, the market may respond negatively.
