AHP–TOPSIS Methodology for Stock Portfolio Investments

This paper presents a methodology for making decisions in the stock market using the AHP-TOPSIS multi-criteria technique. The problem is related to the stock market’s investment process considering the criteria of liquidity, risk, and profitability. The proposed methodology includes integrating economic and financial theories of investment in equity portfolios with the AHP-TOPSIS multi-criteria technique, which allows for evaluating a finite number of alternatives hierarchically under qualitative and quantitative criteria. The methodology has been tested in a real case of selecting a portfolio of high and medium marketability stocks for the Colombian market from April 2012 to April 2017. The computational results show the importance and efficiency of successfully integrating traditional equity portfolio investment criteria and multi-criteria methodologies to find an appropriate balance between profitability and risk in the investment decision-making process in shares in the Colombian stock market. The proposed methodology could be applied to other emerging markets, similar to Colombia.

Socially Responsible Portfolio Selection: An Interactive Intuitionistic Fuzzy Approach

In this study, we address the topic of sustainable and responsible portfolio investments (SRI). The selection of such portfolios is based, in addition to traditional financial variables, on environmental, social, and governance (ESG) criteria. The interest of our approach resides in allowing socially responsible (SR) portfolio investors to select their optimal portfolios by considering their individual preferences for each objective and simultaneous definition of the degrees of acceptance and rejection. In particular, we consider socially responsible portfolio selection as an optimization problem with multiple objectives before applying interactive intuitionistic fuzzy method to solve the portfolio optimization. The robustness of our approach is tested through an empirical study on the top 10 Stocks for ESG values worldwide.

Does Corruption and Government Regulation Matter to Foreign Portfolio Investment: Evidence from Asian and the European Union Countries

Economic integration in various countries impacts fluctuations in and out of capital and multiple economic cooperation between countries. The investment that is one form of implementation of economic integration positively influences a country's capital reserves. The study analyzed the influence of macroeconomic variables and proxied institutions with corruption variables and government regulations on foreign portfolio investment fluctuations in the twenty Asian and EU countries with the largest funds flows. The data used in this study is a data panel with a period from 2002-2019. The analysis method used in this study uses two methods at once, namely the Generalized Method of Moment (GMM) and the Panel Vector Error Correction Model (PVECM), to analyze the cost of the analysis results. The study found that macroeconomic instruments projected with GDP variables had a positive and significant influence on foreign portfolio investments, while exchange rate variables negatively affected foreign portfolio investments. Important findings in this study that corruption consistently negatively and significantly affects foreign portfolio investments are based on both GMM test results and PVECM tests in the long term. In contrast, the results of PVECM tests in the short term do not have any macroeconomic variables or institutions that significantly affect foreign portfolio investment. This means that investors' consideration in investing in Asian countries and Europe is based on a long-term perspective than on short-term economic dynamics. In addition, regulatory variables have a positive and significant effect on foreign investment portfolios in twenty Asian countries and the European Union with the largest portfolio investment fund flow.

Analysing the Influence of Industrial Value - Added of Small and Micro-sized Firms on Regional FDI in Indonesia

The role of Foreign Direct Investment (FDI) has only grown in tandem with globalization, as it plays a dual function by improving capital accumulation whilst simultaneously growing total factor yield, which puts it at an advantage over foreign aids and foreign portfolio investments. Using panel data from 34 Indonesian provinces over the 2015 - 2019 period, this research examined the determinants of provincial FDI and its impact on regional economic development in Indonesia. The random effect method with robust standard error was used to regress the model, and the variables found to be positively significant were the ratio of industrial value added for micro sized firms to regional GDP, as well as the growth rate of industrial value added for small sized firms. Our analysis revealed that micro-sized firms tend to have much higher industrial value added compared to small-sized firms, and that these firms tend to cluster in Western Indonesia. The role of the government should be to foster the growth and competitiveness of small and micro-sized firms, especially for regions where the industrial value added is still low. Further study is suggested on the determinants of industrial value added at the provincial level, as well as more comprehensive research on FDI determinants with a larger dataset.

The nexus between bond liquidity, stock liquidity and foreign portfolio investment

The purpose of this article was to assess the impact of financial market liquidity on international capital flows in emerging markets. Specifically, the research investigates the effect of bond market liquidity and stock market liquidity on foreign portfolio investments using data for five emerging African countries, being Egypt, Kenya, Mauritius, Nigeria and South Africa, for the period 2000 to 2020. The data was sourced from the Bloomberg and World Bank (WDI) databases. Panel data analysis (fixed effects model) was undertaken using three different liquidity measures: the effective spread; Amihud’s (2002) illiquidity measure; and market impact as measured by trading volume. Our findings revealed mixed results. It was found that stock market liquidity attracted foreign portfolio investments. Although bond market liquidity, as measured by the volume of trade, promoted foreign portfolio investment, it was different for the effective spread, as the higher the effective spread, the higher the inward FPI flows, and vice versa. Results on the effects of the bond effective spread on FPI show that as long as the bonds are above the investable grade, investors are not discouraged by the cost of trading. Our findings thus confirm that FPI inflows are predisposed on liquid and efficient host country financial markets. Further, the entrance of foreign investors in the host country’s domestic financial markets, leads to the enhancing of liquidity in the local market, thus increasing risk sharing between local and foreign investors.

The Impact of Geopolitical Risk on Systemic Risk Spillover in Commodity Market: An EMD-Based Network Topology Approach

Since the financialization of commodities, portfolio investments have become an important tool for investors to diversify risks. However, due to the nonlinear fluctuations brought about by extreme events, investors face more difficulties in the choice of risk portfolio. We adopt empirical mode decomposition and STVAR model, along with the basis data of optimized original sample interval. In addition, we retain the mature research of multiscale systemic risk under frequency and divide the dimension of systemic risk into two states. When frequency is combined with states, the risk spillover center undergoes subversive changes, particularly in the longest term, and metals become the risk spillover center, substituting the energy commodity, on the condition that the compositions of extreme value add persuasive power to the perspective of long term. We proposed that the joint fluctuation of agricultural commodities and energy commodities makes the former become another important risk spillover point. For investors, holding period and portfolio both need to be considered.

Revisiting the need to regulate foreign portfolio investor in the Indonesian stock market

This research aims to reintroduce the issue of foreign portfolio investment in Indonesia by way of presenting an analysis on the prevailing Indonesian laws and regulations, comparative analysis with well-established jurisdictions, as well as an evaluation on the need for regulating foreign portfolio investment in Indonesia. The methods used in this research combine normative and empirical methods where a review is conducted on the laws and regulations in Indonesia as well as in South Korea and India as comparative jurisdictions, in addition to an interview conducted with the Indonesian Stock Exchange. The research found that Indonesia does not have a separate, comprehensive set of regulations on foreign portfolio investments yet whereby inferences need to be made from the prevailing laws and regulations that are general in nature. After the comparative overview and analysis, there appears to be a need for separate regulation for foreign portfolio investments in Indonesia, either by way of enacting a completely new set of laws and regulations or alternatively, by way of creating implementing regulations to support the prevailing laws.

TRENDS IN THE DEVELOPMENT OF FOREIGN PORTFOLIO INVESTMENTS IN UKRAINE

The paper reviews the processes of direct and portfolio investment, outlines the differences and the main directions of implementation of ways to achieve economic goals using these tools at both international and national levels. The arguments and reasons for the growing popularity of portfolio investing in the modern world are given, given the wider range of sources of primary information on the state of the stock market in global trading platforms and the ever-increasing tools for managing investors’ assets. Based on the systematization of the work of foreign and domestic scientists, the assessment of the role of investment activity in the formation and further successful development of the national economy is given. Taking into account the experience of developed countries, the need to develop the stock market of Ukraine, identify problems and, taking into account the specifics of the domestic economic and geopolitical space, proposed effective steps to improve the investment climate in our country. In order to detail and classify possible areas of investment activity, the study analyzes the types of investment instruments and identifies their likely target use in modern realities. The analysis of investment activity of Ukraine in the period 2014-2020 provided an opportunity to find out the main trends in the dynamics of changes in direct and portfolio investment. From the point of view of the root causes of the low level of investment activity in this period, gaps in the legislation, the presence of corruption schemes, inconsistencies in the strategies of regulatory financial institutions, a large share of the shadow economy, military action in industrial regions were highlighted. Therefore, despite the high level of return on capital in Ukraine, our country has found itself on the sidelines of global investment flows. The study of the ratio of direct and portfolio investments and their dynamics shows a certain pattern. First, Ukraine is characterized by a constant excess of direct investment over portfolio investment. Secondly, the gap between these types of international capital movements in our country is narrowing due to the increase in portfolio investment. This situation makes it possible to state the invariability of the negative level of investment attractiveness of the domestic economy in the real sector, and the problems of economic imbalance are covered by external borrowing through the use of one of the portfolio instruments, namely placement of foreign and domestic government bonds. The main emphasis is on the inadmissibility of such a state of affairs, which makes it possible only temporarily to maintain Ukraine’s economy in a stable state. A review of the dynamics of the country’s debt growth and the decline in the competitiveness of domestic production in the context of a very high degree of depreciation of production capacity, only confirms the need for urgent measures to stimulate the process of direct investment. Regarding the development of the portfolio investment process, it is proposed to bring the regulatory framework to international standards in the first place. Combining the stimulation of direct investment, especially in the real sector of the economy, in the presence of relevant laws and financial institutions, inevitably revival in the stock market, which in turn will change the structure of portfolio investment in Ukraine. The opinion also expresses the need to take into account the external effects of the investment process, namely to pay attention to increasing the indicators of inclusive economic development.

ESG/Green Investment and Allocation of Portfolio Assets

This article examines the current portfolio allocation in ESG and Green projects. Traditional investments focus on rates of return and risks associated with investment. Environmental, Social and Governance (ESG) or Green factors are additional components that investors have to pay attention to. Environmental protection is very important. However, as we see the current different definitions of ESG or Green factors lead to distorted allocations in portfolio investments. In order to bring portfolio allocations to a desirable direction, global taxation on pollution or creation of an accurate Green credit rating based on emissions of various pollutants are recommended.
