Nations all over the world are becoming interested in the stock market, especially in relation to listing banks and enterprises there, in an era where there are various methods to invest and attain goals. This interest is a result of the stock market’s role in fostering economic growth and its capacity to attract investments and capital from both domestic and foreign sources, all of which are supported by indicators. The purpose of the study is to illustrate how the financial crisis that Iraq experienced after terrorist groups (ISSI) entered the country impacted the country’s overall financial resources. This was done by setting a dummy variable (1) for the years in which the country suffered from the impact of the crisis and making the remaining years an index (0) using ARDL. The relationship that exists between Iraq’s crises and the process of building portfolios of investments in the context of economic downturns that aim to maximize return while minimizing risk. Investment choices are made by economic entities. The goal of the study is to determine whether Iraq’s crises and economic crises in general can be related to the creation of investment portfolios that maximize return while minimizing risk. Investigate hypothesis: Because markets and financial activities are now technologically interconnected, economic crises have a significant impact on investment portfolio management techniques. The study’s conclusions, The panel data model with fixed effects suggests that there should be a correlation between economic crises and the performance of the investment portfolios of banks listed on the Iraqi Stock Exchange. The market price has an adverse effect on the closing prices of the banks in the study sample. The Central Bank’s request to the banks to raise capital up to $250 billion in the years after 2014 may help to explain this, as it led to a rise in the issue of new shares and a decline in the market value of the majority of the banks.
