Institutional investor

An institutional investor is a large organization—like a pension fund, mutual fund, insurance company, or university endowment—that invests money on behalf of its members or clients rather than for personal gain. You'll encounter them constantly in SEC filings (official documents companies submit to regulators), where they're listed as major shareholders. They matter because when institutions buy or sell large chunks of stock, it can move prices and signal confidence in a company. For example, if a major pension fund reveals it just bought 5% of TechCorp Inc., that's often a sign they believe the company has solid long-term potential. Institutions have more resources and research power than individual investors, so tracking their moves can be useful.
