Portfolio investments are often considered financial or speculative. Foreign portfolio investments, as opposed to strategic ones, are designed to have a higher financial return than in the home country. Portfolio investments are purely financial assets, such as stocks or bonds, that do not provide control over a company. Although foreign direct investment can also be a financial asset, and if this investment is 10 percent or more of the value of the voting stock, then it will be considered direct, even if the goal is a higher return. If less than 10 percent of the voting stock of a particular organization are invested, such investments are considered portfolio. While engaging in portfolio investment, using stocks, the investor provides capital in exchange for a predefined payout or return at regular intervals, depending on the profitability of the company being invested in (Dyck et al. 2019). Also, the portfolio investor can expect an increase in value in the future and a more expensive sale of shares than the purchase price. For this reason, these investments also have the name of speculative investments. Portfolio investments can also be made in closed type organizations, but most of them go to organizations openly listed on the stock exchanges.
To attract investment, organizations often decide to trade shares publicly, through stock exchanges. The trading of shares through stock exchanges has greatly contributed to the growth of portfolio investments. However, the trading of shares through stock exchanges is much more strictly regulated than the trading of shares of unlisted companies. One of the main limitations of trading shares through stock exchanges is the lack of connection with the organizational activities. Only those who do not have access to internal organizational information have the right to buy shares. If it is found that the shares were purchased with the knowledge of insider information, this is considered “insider trading” and is a punishable offense eventually leading to imprisonment. Before making a foreign direct investment or a strategic investment in an organization, an investor almost always familiarizes himself with the inside information of the company, because it is important in making the decision to invest and take control of the company. In the case of a foreign portfolio investment, if the investment is made in companies listed on the stock exchange, the only way to get information about the organization is through public announcements officially provided by the organization. However, the public announcement is usually related to the disclosure of historical data – the disclosure of financial results, but data about the company’s weaknesses, strengths, and threats are not really disclosed, and the investor must be guided only by historical data and his own calculations and assessments. Investing in foreign organizations without access to insider information is quite risky, that is why derivatives aggregated products are often offered on exchanges. This means that an investor can invest, not in the shares of a specific company, but, for example, in the aggregated index of all listed companies in a certain sector of that country. An aggregated index is created as a derivative index of the values of shares of several, several dozen or several hundred companies. Investments in aggregate indexes are less risky because they do not depend on the success of a specific organization or casual mismanagement, but on the entire sector. Even if one or a few organizations face very serious issues, this does not necessarily mean that the entire sector gets affected, and the average value of the aggregated index may suffer little or no damage as a result. In this way, the investor becomes protected from the problems of individual organizations. In addition, it is much easier for an investor who does not have inside information about specific companies to evaluate the entire sector, such as the industrial sector, the electronics sector, the high-tech sector, and its development trends, as it is possible to follow the available macro indicators. Portfolio or financial investments are primarily made through financial institutions such as banks and mutual funds.
Investors in the economically developed countries actively trade shares through stock exchanges. For example, the three most famous stock exchanges in the USA – NYSE – New York Stock Exchange, NASDAQ – National Association of Securities Dealers Automated Quotations, AMEX – American Stock Exchange. The history of the stock exchange goes back 18 centuries, when in 1792 when the Buttonwood Agreement was signed between 24 brokers at the Buttonwood tree on Wall Street. Previously, transactions were carried out in stock exchange halls, where market participants gathered. The share trading mechanism operated on the principle of an open auction, the so-called “Open Outcry system”. Sellers call out their offer to sell, and buyers either accept their offer or call out their price to buy.
European countries also have stock exchanges, the largest of which is in France are SBF / PAR – Euronext France Paris, FWBFrankfurt Stock Exchange and IBIS / FSE – Deutsche Borse XETRA in Germany. In Asia, the largest SHEK /HKEX – Hong Kong Stock Exchange, SEHKSZSE – Shenzhen-Hong Kong Stock Connect, TSEJ / TYO – Tokyo Stock Exchange, in Africa – JSE – Johannesburg Stock Exchange, South America – MEXI Mexican Stock Exchange.
Through stockbrokers, investors can purchase shares of companies listed on stock exchanges in various continents. This process is relatively short and fast, thanks to standardized procedures. There were roughly 80 major stock exchanges with a worth of 110.2 US dollars trillion in total in 2023. Top 25 stock exchanges are covering 96 percent of total value (Exhibit 6-4). A most prominent stock aggregated index is that reflect the entire sector or even the share values of all publicly listed companies. For example, technology sector shares are represented by indexes such as NASDAQ, TECDAX30 Germany Technology 30, and US industry – Dow Jones Industrial Average – DIJA.

Sometimes non-sectoral indexes are compiled by country. For example, the German market situation is reflected by the DAX 40, the S&P 500 by the United States, the CAC40 by France, and the JP225 by Japan.
Most of the foreign investments before the World War I were of this type and mainly from the United Kingdom went to the construction of US railways, the industrialization of the new territories, the creation of settlements in the US. International portfolio investment market collapsed after the World War I in US and was not able to recover until1960s. The collapse of the stock market in the USA is associated with the Great Depression, the most severe and prolonged global economic crisis that took place in 1929-1933. A massive economic recession and a stock market rally in unemployment led to the emergence of fringe political forces and even the National Socialist Party in Germany which won democratic elections and elected Adolf Hitler to rule. After only 6 years later, he was the one who started the deadliest World War II of all time, marking a dark chapter in the history of armed conflict between humans.
Portfolio or financial investments are primarily made through financial institutions such as banks and mutual funds. The motives for international portfolio investments are associated with the desire to earn higher returns abroad. Thus, residents of one country buy bonds or stocks of another country if the return on bonds or stocks in the other country is higher. Residents of one country may also purchase shares in foreign corporation if they expect future profitability to be higher than that of domestic corporations.
Another motive is risk diversification and uncertainty, to the extent that no one really knows which corporation will do well and which will do poorly. As different individuals may have different expectations for the same stock, it is possible that some investors in each nation consider that the foreign corporation stocks are better to buy. It also explains the bidirectional nature of international portfolio investments.
Portfolio investment is more about speculative activity, hoping to earn from the sale of shares later or from dividends, but not to control the performance of the organization itself. Portfolio investments are typically used for listed organizations with long traditions and experience, aggregated stock indices of these organizations, or to funds managing many investments. However, in the second decade of the 21st century, portfolio investments have become important when it comes to accumulating and mobilizing capital for start-ups. Start-ups are mainly technological companies that develop a new product. The peculiarity of a start-up is that it has high costs at the beginning of its activity, and relatively little or no income. Thus, the start-up business is based on the theory of expectations and the theory of probability. Only one of many start-ups can be successful. Thus, investments in start-ups are usually made by diversifying the risk, investing in many start-ups and hoping that the success and profits of one of them in the future will pay off the costs and losses of all the failed start-ups. Due to multiple investment reasons, investments are frequently done through funds and other crowdfunding mechanisms. Often, when a start-up proves its potential for success, strategic investors are also interested in it. Large corporations closely monitor the global start-up market, and when a start-up presents an interesting technological solution or product, global corporations or early-stage investors often acquire a controlling stake in that start-up. The objectives of such acquisition are twofold. Firstly, a global organization may perceive a risk to its own business, especially if a start-up offers an innovative solution that challenges its existing business model. So, there are many experiences where a start-up is simply bought to stop or delay developing its technology. Another goal is to accept the start-up as one of its strategic partners, and after purchasing the start-up’s shares, to block competitors from accessing the innovative product or technology created by the start-up. However, such investments in already advanced start-ups are considered strategic investments.
Another aspect is taking control of the organization through portfolio investment. There are cases when an organization aims to take over another organization, such as a competitor or a vertical alliance partner. If such a target is listed on the stock exchange and there is no possibility to make a direct strategic investment, successive share purchases on the stock exchange can be used as a solution to acquire a controlling stake and to tilt the acquired company’s strategy in its favor. Some countries have restrictions on such predatory portfolio investments; however, this method remains relevant.
The advantage of a portfolio investment in a foreign organization or aggregated stock index is the ability to earn from the sale of shares later or to have a regular return from profits and dividends. It depends on strategy and intentions of investor. The disadvantage of a portfolio investment is low control in a foreign organization or aggregated stock indexes.
