Institutional investors are large shareholders managing large amounts of money for clients. They include pension funds, mutual funds, exchange traded funds, insurance companies, hedge funds, and some very high net worth family trusts. This is the so-called “smart money”. Large trades executed by institutional investors can move markets. Many of these types of investors must register with the SEC and report their holdings every quarter. Based on SEC filings, Zacks tracks the equity holdings of institutional investors, both in terms of which institutional investors are shareholders in each stock, and which stocks are owned by each institutional investor.
