The purpose of this paper was to model, with the help of neutrosophic fuzzy numbers, the optimal financial asset portfolios, offering additional information to those investing in the capital market. The optimal neutrosophic portfolios are those categories of portfolios consisting of two or more financial assets, modeled using neutrosophic triangular numbers, that allow for the determination of financial performance indicators, respectively the neutrosophic average, the neutrosophic risk, for each financial asset, and the neutrosophic covariance as well as the determination of the portfolio return, respectively of the portfolio risk. There are two essential conditions established by rational investors on the capital market to obtain an optimal financial assets portfolio, respectively by fixing the financial return at the estimated level as well as minimizing the risk of the financial assets neutrosophic portfolio. These conditions allowed us to compute the financial assets’ share in the total value of the neutrosophic portfolios, for which the financial return reaches the level set by investors and the financial risk has the minimum value. In financial terms, the financial assets’ share answers the legitimate question of rational investors in the capital market regarding the amount of money they must invest in compliance with the optimal conditions regarding the neutrosophic return and risk.

The article is devoted to the research of theoretical principles of development of such components of the financial market as the money market and the capital market, identification of key differences between them on the basis of the analysis of scientific professional literature and key provisions of the legislative framework, substantiation of the general interpretation of their essence that could be used in international practice. The article analyzes the peculiarities of formation and functioning of each type of markets, traditional differences between them, examines international practice and statistics on the use of these terms by economic agents, defines the legal basis for understanding their essence and the legal basis for the delineation of these two types of markets. It is proved that a thorough analysis of the peculiarities of the functioning of individual markets, the frequency, and popularity of the use of their definitions in economic practice, the definition of users of these types of markets and their functions, form the prerequisites for clarifying the definitions of the essence of each of these markets, with their further global harmonization. The result of the research is the authors’ own interpretations of the concepts of the “money market” and “capital market”. The money market offers an understanding of the transaction system for the purchase and sale of liquid cash or other short-term financial assets, which typically include short-term financial liabilities (up to one year), the purpose of which is usually to provide financing for current operations, short-term profit or financial risk management in the short-term. The capital market is defined in the article as a system of transactions for the purchase and sale of financial assets, which include securities, derivatives, or financial transactions, which usually involve long-term financial liabilities, the purpose of which is to satisfy capital requirements or increase capital. Keywords: money market; capital market; financial market; legal basis; international practice, definitions.

(2) knowing the ideal investment instrument based on established criteria. The criteria used in this study include seven criteria, namely: investment performance criteria, risk criteria, liquidity criteria, macroeconomic factor criteria, individual circumstance criteria, psychological factor criteria, and demographic criteria. The respondents in this study were five experts from academics, practitioners, and regulator. The major findings of the research are (1) the criteria to be considered in choosing Islamic capital market investment instruments are divided into investor criteria and capital market criteria. Investor criteria include; psychological factors (motivation and self control), individual circumtances (financial literacy), demographics (income and education). Capital market criteria include: investment performance (capital gain, yield, and fundamental analysis), risk (financial risk, market risk and management risk), macroeconomic factors (exchange rates and gross domestic product), liquidity (liquidity ratio). (2) the alternative with the highest priority is sharia mutual funds, then sukuk and sharia stocks</em><em>.</em></p></div>

This paper studies the problem of neutrosophic portfolios of financial assets as part of the modern portfolio theory. Neutrosophic portfolios comprise those categories of portfolios made up of financial assets for which the neutrosophic return, risk and covariance can be determined and which provide concomitant information regarding the probability of achieving the neutrosophic return, both at each financial asset and portfolio level and also information on the probability of manifestation of the neutrosophic risk. Neutrosophic portfolios are characterized by two fundamental performance indicators, namely: the neutrosophic portfolio return and the neutrosophic portfolio risk. Neutrosophic portfolio return is dependent on the weight of the financial assets in the total value of the portfolio but also on the specific neutrosophic return of each financial asset category that enters into the portfolio structure. The neutrosophic portfolio risk is dependent on the weight of the financial assets that enter the portfolio structure but also on the individual risk of each financial asset. Within this scientific paper was studied the minimum neutrosophic risk at the portfolio level, respectively, to establish what should be the weight that the financial assets must hold in the total value of the portfolio so that the risk is minimum. These financial assets weights, after calculations, were found to be dependent on the individual risk of each financial asset but also on the covariance between two financial assets that enter into the portfolio structure. The problem of the minimum risk that characterizes the neutrosophic portfolios is of interest for the financial market investors. Thus, the neutrosophic portfolios provide complete information about the probabilities of achieving the neutrosophic portfolio return but also of risk manifestation probability. In this context, the innovative character of the paper is determined by the use of the neutrosophic triangular fuzzy numbers and by the specific concepts of financial assets, in order to substantiating the decisions on the financial markets.

Abstract We analyse whether the determinants of capital found in the previous literature hold for the special German banking sector comprising three characteristic banking groups including savings banks, cooperative banks and other banks, which differ regarding their ownership and their access to the capital market. Through the use of accounting data from German banks between 1992 and 2001 we find evidence in accordance with the buffer theory of capital for all German banking groups. Furthermore, we also detect some remarkable differences between the three banking groups regarding their determination of capital due to institutional characteristics.

Research background: Investing in the capital market is one of the ways for an investor to increase his income. Investing in the capital market is described as very risky, but it provides us with an opportunity to achieve high returns. There is an infinite number of assets on the market that an investor can include in his portfolio, and which assets he chooses to invest in will ultimately affect the return and risk of the created portfolio. Therefore, the investor should think rationally and should try to reduce the risk of his investment. Purpose of the article: This article aims to point out the effect of diversification through the creation of a portfolio of financial assets. Methods: This paper uses modern portfolio theory and focuses on the use of the Markowitz model. The optimal weights of individual assets in the compiled portfolio are calculated using the Lagrange function. We use data on weekly closing prices of individual stocks, commodity and mutual fund. Findings & Value added: The main finding was that the risk associated with the created portfolio is lower than the risk associated with investing in individual assets.

Acording to the author's opinion, institutional investors (from many participants of the capital market) play the main role, especially investment funds. They supply to small-sized investors special investment services, which allow them to participate in the investment process. However excessive institutialization and increasing number of hedge-funds may lead to financial crisis.
