The Securities and Exchange Organization, as the supervisory body of Iran's capital market, regulates and supervises self-regulatory organizations, financial institutions and publishers. This organization operates through self-regulatory organizations including Tehran stock exchange, over-the-counter, commodity exchange, Energy exchange, central depository and settlement of funds and centers by providing a suitable and efficient trading system for the Exchange and settlement of trades. After the comparative study of the regulatory system in the capital market structure of the selected countries, this research intends to root out operational inefficiencies in the communication structure of the Iranian capital market supervisor and self-regulatory organizations through interviews with scientific and executive experts in this field. And while analyzing the existing situation in the current structure of the capital market, using the qualitative content analysis method to provide an operational framework to determine the boundaries of the decisions, powers and actions of the capital market elements in terms of policy, supervision and implementation, in order to detect and eliminate the gaps, Possible overlaps and clashes, especially in regulatory matters, have also been prevented, and while the communication between the elements, the independence of each is also maintained at an optimal level.

Optimum financing of economic enterprises is a necessary action that can improve the quality and quantity of domestic industries in the prevailing competitive environment and ultimately lead to the economic growth and prosperity of the country. Investigations show that some of the production plans in the country, such as steel projects, are defined with liquidity problems in order to achieve production capacity, therefore, considering the importance of steel projects in the country's economy, so far the issue of choosing the optimal method of financing the relevant industry as a No special attention is needed. Therefore, in the current research, we are seeking to discover the most optimal financing model for Iran's steel industry based on a series of specific criteria. In this study, through the statistical technique of multi-criteria decision-making and the design and distribution of a questionnaire to experts in order to prioritize the financing methods of the steel industry, which were extracted through a semi-structured interview, and the analysis and final ranking of the obtained information Using the TOPSIS method, the factors and financing methods of the steel industry were evaluated, and in this regard, pairwise comparisons were used to rank the factors and weights. The results of this study indicate that the project fund option compared to other options, including: construction, exploitation and ownership, parallel istisna, bonds convertible into shares, partnership bonds and lease bonds are of the highest priority according to It has components and criteria such as reasonable cost, etc. compared to other financing options, so it is suggested that companies active in the steel industry in the country prioritize financing in this way.

One of the recent developments in the Islamic securities market is the issuance of Socially Responsible Investment Sukuk (SRI), which focuses on environmental, social and governance (ESG) issues. Despite the dramatic growth of these papers over the past few years, only a handful of studies have addressed this issue. Therefore, the purpose of this study is to systematically review the literature on Islamic securities investment with social responsibility in order to provide comprehensive guidance for future research. A total of 383 articles from the Science and Scopus Network database were selected for analysis of bibliographic studies during the years 2000 to May 2021.
The present study shows that the literature of SRI Sukuk is mainly in 10 areas (1) definition of SRI Sukuk (2) competitiveness (3) types (4) nature of risk and return (5) terms and characteristics of plans and projects Eligible (6) Defines strategies for selecting eligible projects (7) Measures and indicators of effectiveness (8) Potential actors (9) Motivational policies and (10) Monitoring and reporting methods شد. However, there are very few studies on the criteria and indicators of effectiveness and the conditions and characteristics of eligible designs and projects of this type of sukuk.
Research also shows that the United States, the United Kingdom, China, Germany, Australia, and Italy have done the most research on socially responsible investment sukuk.

Project financing is one of the most important and practical approachs developed and developing countries and many medium and large scale projects in the world are implemented by using this approach.Unfortunately, this approach has not really been able to Be implemented in iran our country, and one of the main reasons for this failure is the lack of knowledge and explanation of the requirements and dimensions of this method. Due to the bank-based nature of the Iranian economy, it seemed that the best place to start and practice this method of financing is for banks to take steps in this field and allocate a small part of their resources to this method.For this purpose, in this research, Tried to while better understanding the subject, the main factors affecting the realization of the project financing model in the banking system of the Islamic Republic of Iran with a relatively comprehensive review of domestic and foreign scientific resources are counted and then In order to extract the final model, By using the Theme analysis method and using the opinions of experts and research literature, a relatively deep analysis was done and a total of 2072 basic themes were extracted and by measuring and rearranging these factors, the operational model of project financing in the banking system of the Islamic Republic Iran was extracted.

Project financing is one of the most important and practical instruments in developed and developing countries and many medium and large scale projects in the world are implemented by using this approach. Unfortunately, this approach has not really been able to Be implemented in Iran our country, and one of the main reasons for this failure is the lack of knowledge and explanation of the requirements and dimensions of this method. Due to the dynamics of the capital market and emerging tools such as the private Equity fund, the project financing approach can be effectively used in these structures and the resources and supports of institutional and banking investors, etc. be used within the framework of this structure and project financing approach.For this purpose, in this study, while better understanding the issue, a relatively comprehensive review of internal and external scientific sources and obtaining expert opinions to design the model using thematic analysis method and by measuring and rearranging these factors, The operational model of using a private Equity fund to implement project financing In order to implement project financing in Iran, from the study and project selection phase to the evaluation, and finally the completion, operation and implementation of the private investment fund exit policy from the company were extracted

Financing, and specialy project financing, is always affected by numerous financial and non-financial risks. Success in financing requires examining and explaining the impact of these risks on each other and on financing so that in the next step, an appropriate solution can be implemented to hedge the risks. Special circumstances and much uncertainties in our country have doubled the importance of conducting such research. For this purpose, in order to better understanding the issue, the set of risks affecting financing in general and project financing in particular with a relatively comprehensive review of internal and external scientific resources examined and then based on experts' opinions by using Dematel method in a fuzzy environment were prioritized and internal relationships of factors were extracted.Based on the analysis of experts' opinions by fuzzy dematel method, the research findings indicate that risks due to economic conditions and instability, exchange rate risk, political risk, rules and regulations risk are the highest among the risks affecting project financing. And other factors are in the next ranks. Also, risks arising from laws and regulations, economic conditions and stability, human resource risk, political risk, inflation risk, government and governance risk and the risk of coercive events in addition to their direct effect, as maternal risks and affect other risks.

According to the research findings, political and economic stability, legal issues, regulation of strong contractual relations, accurate feasibility studies and strong financial structure have the greatest impact and degree of importance in realizing the project financing model in the banking system of the Islamic Republic of Iran. And other factors are in the next ranks. This research is the first step in order to explain this practical method of financing as much as possible, and in the next research, it is necessary to take additional and more detailed steps.

One of the most important topics in financial markets in recent decades is the forcasting. The main purpose of this study is to forcast volatility future prices. In this research, four groups of symmetric GARCH (GARCH), exponential GARCH, FIGARCH and multi-regime GARCH models have been estimated and forecasted using normal distribution, t-distribution and GED distribution. According to the model error for forecasting fluctuations, the Markov Switching GARCH model (MS-E-GARCH) is reported to be the most efficient model to forecast the fluctuations in the gold coin futures market. The results of the estimation by the Markov Switching GARCH model (MS-E-GARCH) show that fluctuations of gold coin futures market are predictable; and as a result the gold coin futures prices do not have the weak form of efficiency in both low and high volatility settings and systematic profits could be achieved in this market. According to the results of the study, the accuracy of MS-E-GARCH model is higher for GED distribution in comparison with other models.

  The company’s decisions about its capital structure and financial are the influential factors that can shape or change investors’ ideas about a company trades and stock price. In this research, the effect of Islamic financial instrument (Sukuk) on risk adjusted return and stock trading value is investigated. To examine the relationship between the variables, The Event Study method was implied for 5 days (one day prior to the distribution to three days afterwards). The sample is chosen from Sukuk issuers listed in Tehran Stock Exchange within the period of 2010-2015. Based on the data gathered from Tehran Stock Exchange database, the sample includes 20 issuing events. The empirical tests and robustness test (different event windows implied) results show that the research hypotheses (the existence of relationship between issuing Sukuk and risk adjusted return and daily trading value of the company stock) are rejected. This research concludes that there is no significant relationship between issuing Sukuk and risk-adjusted return. In addition, there is no significant relation between issuing Sukuk and daily trading value of the company stock. These results might be due to the fact that using such stock exchanges in Iran has just flourished; hence, the effects of applying these instruments are not yet specified for the investors.

In the process of evolving portfolio theory, In order to eliminate the defects and basic assumptions limitation of the traditional model, the concept of downside risk and the Mean-LPM model has been introduced.
The Lower Partial Moment (LPM) has been the downside risk measure that is most commonly used in portfolio analysis. Its major disadvantage is that its underlying utility functions are linear above some target return. As a result, the upper partial moment (UPM)/lower partial moment (LPM) analysis has been suggested in the recent researches. The UPM-LPM framework is powerful because it implements the full richness of economic utility theory such as Morgenstern economic utility function and prospect theory.
In this study, using by stock market Sector indexes over 3 years period since 2010 to 2012, the mean-variance and UPM/LPM optimal portfolio has been calculated in different degrees of potential and risk aversion. In the next step, the optimal portfolio performance of both model has been measured over second period from 2013 to 2015. This research used MATLAB software for optimizing and analyzing of portfolio selection models.
The Jobson-Korkie test has been used to measure the portfolio performance difference between Mean-Variance and UPM-LPM model. It was found that there is significant difference between results of Sharp ratio in Markowitz portfolio and UPM-LPM portfolio, and in the different risk/potential aversion approaches the UPM-LPM portfolio are significantly better than the traditional Markowitz model

One of the most important topics in financial markets in recent decades is the market efficiency. The efficient market hypothesis states that all available information is fully and immediately reflected in asset prices, therefore it is not possible to achieve systematic profits by price forecasting. The main purpose of this study is to evaluate the weak form of efficient market hypothesis for gold coin futures market in two settings of low volatility and high volatility of returns.
In order to test the weak form market efficiency in prices of gold coin futures market, Markov-switching GARCH and Markov-switching autoregression methods have been applied to the period from 2008 to 2017. The results of the FIGARCH and FARMA models indicate the fact that the series have long term memories of risk and average returns. The results of the estimation for the Markov-switching GARCH model (MS-E-GARCH) and the Markov-switching autoregression (MS-AR) imply that both risk and average return of gold coin futures market is predictable, and as a result the gold coin futures market does not have the weak form of efficiency in both low and high volatility settings and systematic profits could be achieved in this mark

This Article by applying descriptive- analytical method answers the following questions: Based on Imamiyah juridical school, is it possible to issue floating-rate and inflation-protected musharakah sukuk? What are the correcting solutions consistent with finance knowledge? The results of the study show that it is possible to issue inflation-protected musharakah sukuk with floating provisional rate. In order to float the rate of return, difficult solutions may be offered such as floating provisional rate with call option and floating provisional rate with call and put option.
In recent years, inflation-protected bonds have developed in the world and have been invested in most of portfolios. The goal of these bonds is to ensure purchasing power by directly linking returns to inflation for the bond's entire term. Linkers, therefore, contain two forms of payment: the real interest that is fixed at the beginning of the term, and compensation for the loss of purchasing power. Thus, the asset class presents an ideal opportunity to a broad range of investors for protection against inflation. Iran as a country that has high and variable inflation can use these securities for financing long and mid-term projects, especially in public construction projects.

The capital market is a bridge that transfers the savings of economic units with excess resources to investment units that need them. Using the capital market to finance the government expenses is among the most common form of financial transactions. Therefore the capital market is considered one of the major players of financing in the economy of any country. Iran’s capital market began its rapid development process in 2005 and within the past decade many financial institutes were formed by financing from the aforesaid market. Due to being new in Iran, the relation between the diverse and scattered components of the capital market has not been provided as a comprehensive model. The purpose of the present study is to investigate the structure and identify the aspects of financing services through Iran’s capital market that due to dynamic complexities of the issue (numerous players and interested parties, diverse and multiple aspects of services and conflict of interests between interested parties), soft systems methodology was used to study the current status. Therefore, in addition to performing triple analyses of cultural analysis and illustrating the rich picture of the current status, CATWOE analysis and root definition by holding numerous sessions with the interested parties were extracted that demonstrates how the financing process must be by including real world conditions. Results indicate that to improve the issue, changes in financing services processes must be implemented that emphasis on identifying and analyzing factors of market attraction, regulatory bodies and status of laws and regulations.

One of the most useful tools in the risk management and portfolio management is "stock index futures contracts". Applications such as various portfolio risk management, single stock risk management, index arbitrage, spreading and others have made them one of the most popular derivative securities with investment managers. However, sharia studies by Shia and Sunni scholars in the field of Islamic financial instruments have provided some reasons against using these securities due to their creating some challenges. To remove these jurisprudential inhibitions, this paper suggests "index funds futures" rather than stock index futures contract. Nowadays, there are mechanisms and legal infrastructures that are required for setting up index funds in stock markets. Index funds are therefore used that can create return after costs of fund along with minimum tracking errors. This study, while pointing out different dimensions of stock index futures and index fund, determines what type of stock index has similar behavior to index of Iranian capital market. The research is descriptive and relies on analytical – deductive methods and library documents.
