It is possible to rank marketing strategies to make the best decision to deal with the risks facing businesses. Methodology: Based on preliminary studies conducted on SMEs in Iran, a four-part questionnaire with a five-point Likert scale was provided to entrepreneurs and managers of SMEs in Tehran. Data related to 20 questionnaires were analyzed using SPSS software. Cronbach's alpha method was used to determine the reliability of the questionnaire. Finding: The results reveal that financial strategies, customer, relationships and online marketing do not have the same effect on entrepreneurial risks and we can rank them. Also, in examining the impact of business strategies on risks, the results showed that planning strategy has the greatest impact on reducing credit, operational and liquidity risks whilst relationship strategy has the greatest impact on reducing market risk. Online marketing strategy has the least observed effect on reducing credit risk and operational risk, and direct marketing strategy and financial strategy have the lowest effect on reducing liquidity and market risks. Conclusion: The effect of business strategies on reducing entrepreneurial risks is confirmed and we can rank strategies based on their impact on the risks facing businesses. Entrepreneurial risks can be reduced by using marketing strategies, and in conditions of uncertainty, the use of knowledge and expertise of marketing consultants can lead to improved decisions of entrepreneurs, resulting in sustainability and growth of businesses.

Analysis of investors’ behavior is a new scientific field in financial behavior, which is a good tool for acquiring this knowledge. Uncertain circumstances cause investors to make systematic mistakes and face cognitive biases in their expectations and decision making, including in assessing stock returns.

Multivariate regression analysis was performed using Eviews 9 software. The results show that by controlling year and industry effects, investors use profitability for most of the past years in following the pattern of belief updating based on two indicators of reducing realized earnings per share and equity returns. The research model is also confirmed by the sensitivity analysis and controlling company effects based on the equity return index. However, it is not confirmed by the two indicators of realized earnings per share and return on assets.
