A more thorough explanation:

A single-country fund is a type of mutual fund that invests in securities of companies located in a specific country outside the United States. It is a type of investment company that pools money from multiple investors to invest in a diversified selection of securities.

For example, a single-country fund may invest only in companies located in Japan or Germany. This type of fund allows investors to gain exposure to a specific country's economy and potentially benefit from its growth.

Investing in a single-country fund can be risky because it is heavily dependent on the economic and political conditions of that country. However, it can also provide higher returns if the country's economy performs well.
