At present situation of country and separate economic sanction from western countries now this question arises how is spillover effect at different situation of economic sanction? So, to answer this question this paper investigates spillover effect at different economic sanction periods. In this order we collect daily data of sock, currency and gold coin markets for the periods of 2009 to 2021 by applying the VARMA-AGARCH model for analyzing and surveying. For more precise survey of sanction role in return spillover we divided research periods into 4 sub periods included 2 periods of harsh sanction and 2 periods of no harsh sanction. Result present direct and positive relation between intensity of sanction and return spillover effect in markets that causes unstable and disorder in markets by capital shifts in different markets. so we conclude that sanction has very important role in return spillover for different periods of research.

Purpose: Diversification is an essential component of risk management in the investment field. Among the various methods at hand, the establishment of an equal-weight stock portfolio is widely acknowledged as a simple and efficient strategy. This research aims to introduce a new approach based on the equal-weighted stock portfolio strategy to enhance its efficiency in managing risk and making financial decisions.
Methodology: The proposed approach integrates the equal-weight stock portfolio strategy with risk measurement and evaluation tools. By employing common risk measures from the investment management literature, stocks are first evaluated and screened. The remaining stocks are then used to form an investment portfolio using the equal weight portfolio strategy. The risk measures utilized in this research encompass variance, standard deviation, semi standard deviation, value at risk, conditional value at risk, entropic value at risk, drawdown at risk, conditional drawdown at risk, and entropic drawdown at risk.
Findings: To evaluate the performance of the proposed approach, an experimental case study is conducted using monthly historical data of S&P 500 index symbols. The results are compared with those obtained using the traditional equal-weight stock portfolio formation approach. The empirical findings of this study carry practical implications for investors and investment fund managers.
Originality/Value: This research contributes to the field by offering an innovative perspective on stock screening and investment portfolio formation, which can also serve as a valuable measurement criterion.

In service organizations such as banks, transportation industry, medical services, insurance, hotels, etc., the appropriate and predicted structure of profitability is more sensitive. Because the customer is considered a part of the service provided in the process of providing services, the solutions should be taken towards the personalization of these services for each customer and a sense of confidence should be created for the customer in relation to the profitability of these organizations. Part of the ownership of banks and financial institutions is in the hands of major shareholders, government organizations, banks (especially investment banks).

Today, some scholars believe that exchange rate Volatility may reduce the arrival of tourists . Therefore, the purpose of this study was to investigate the effect of exchange rate Volatility on the tourism flow in the Iranian economy during the period from the first quarter of 2000 to the fourth quarter of 2020 . In most of the past surveys, the standard deviation of the moving average of the exchange rate logarithm has been used as a criterion for calculating exchange rate Volatility, but in this research, a new criterion was used to assess exchange rate Volatility.The research method used is based on the cointegration theory, including the correction of the error of the exchange rate Volatility criteria using the ARDL econometric model for cointegration . The results showed : a ) In addition to the attractions of visiting countries as expected, the ratio of GDP per capita to relative proportions has a positive and significant impact on the flow of tourism b ) Relative prices in most cases are negative and meaningful, meaning that the relative price level between the country of origin and destination has a significant and negative effect c) The exchange rate Volatility affect the flow of tourism and the arrival of tourists.
