PORTFOLIO INVESTMENT: The acquisition of financial assets (which includes stock, bonds, deposits, and currencies) from one country in another country. In contrast to foreign direct investment, which is the acquisition of controlling interest in foreign firms and businesses, portfolio investment is foreign investment into the stock markets. Most economists consider foreign direct investment more useful than portfolio investment since this last one is generally regarded as temporal and can leave the foreign country at the first sign of trouble.
