Index fund in the context of "Mutual fund"

An institutional investor is an entity that pools money to purchase securities, real property, and other investment assets or originate loans. Institutional investors include commercial banks, central banks, credit unions, government-linked companies, insurers, pension funds, sovereign wealth funds, charities, hedge funds, real estate investment trusts, investment advisors, endowments, and mutual funds. Operating companies which invest excess capital in these types of assets may also be included in the term. Activist institutional investors may also influence corporate governance by exercising voting rights in their investments. In 2019, the world's top 500 asset managers collectively managed $104.4 trillion in Assets under Management (AuM).

Institutional investors appear to be more sophisticated than retail investors, but it remains unclear if professional active investment managers can reliably enhance risk-adjusted returns by an amount that exceeds fees and expenses of investment management because of issues with limiting agency costs. Lending credence to doubts about active investors' ability to 'beat the market', passive index funds have gained traction with the rise of passive investors: the three biggest US asset managers together owned an average of 18% in the S&P 500 Index and together constituted the largest shareholder in 88% of the S&P 500 by 2015. The potential of institutional investors in infrastructure markets is increasingly noted after the financial crises in the early twenty-first century.

Passive management (also called passive investing) is an investing strategy that tracks a market-weighted index or portfolio. Passive management is most common on the equity market, where index funds track a stock market index, but it is becoming more common in other investment types, including bonds, commodities and hedge funds. There has been a substantial increase in passive investing over the last twenty years.

The most popular method is to mimic the performance of an externally specified index by buying an index fund. By tracking an index, an investment portfolio typically gets good diversification, low turnover (good for keeping down internal transaction costs), and low management fees. With low fees, an investor in such a fund would have higher returns than a similar fund with similar investments but higher management fees and/or turnover/transaction costs.

In finance, a stock index, or stock market index, is an index that measures the performance of a stock market, or of a subset of a stock market. It helps investors compare current stock price levels with past prices to calculate market performance.

Two of the primary criteria of an index are that it is investable and transparent: The methods of its construction are specified. Investors may be able to invest in a stock market index by buying an index fund, which is structured as either a mutual fund or an exchange-traded fund, and "tracks" an index. The difference between an index fund's performance and the index, if any, is called tracking error.

A bond index or bond market index is a method of measuring the investment performance and characteristics of the bond market. There are numerous indices of differing construction that are designed to measure the aggregate bond market and its various sectors (government, municipal, corporate, etc.) A bond index is computed from the change in market prices and, in the case of a total return index, the interest payments, associated with selected bonds over a specified period of time. Bond indices are used by investors and portfolio managers as a benchmark against which to measure the performance of actively managed bond portfolios, which attempt to outperform the index, and passively managed bond portfolios, that are designed to match the performance of the index. Bond indices are also used in determining the compensation of those who manage bond portfolios on a performance-fee basis.

An index is a mathematical construct, so it may not be invested in directly. But many mutual funds and exchange-traded funds attempt to "track" an index (see index fund), and those funds that do not may be judged against those that do.
