Institutional investors are organizations that invest large sums of money on behalf of their members or clients. These entities include pension funds, insurance companies, mutual funds, and hedge funds. They typically manage investments in stocks, bonds, real estate, and other assets, aiming to generate returns over the long term. Unlike individual investors, institutional investors have significant resources and expertise, allowing them to influence market trends and corporate decisions. Their large-scale investments can impact the economy and financial markets, making them key players in the investment landscape.
