Hedge Funds
A hedge fund is a pooled investment fund that holds liquid assets and that makes use of
                                complex trading and risk management techniques to improve investment performance and
                                insulate returns from market risk. Among these portfolio techniques are short selling
                                and the use of leverage and derivative instruments.
While most modern hedge funds are able to employ a wide variety of financial
                                instruments and risk management techniques,[5] they can be very different from each
                                other with respect to their strategies, risks, volatility and expected return profile.
                                It is common for hedge fund investment strategies to aim to achieve a positive return on
                                investment regardless of whether markets are rising or falling ('absolute return').
                            
Hedge funds are considered alternative investments. Their ability to use leverage and
                                more complex investment techniques distinguishes them from others. Other than a fund's
                                regulatory status, there are no formal or fixed definitions of fund types, and so there
                                are different views of what can constitute a 'hedge fund'.
A hedge fund usually pays its investment manager a management fee (typically, 2% per
                                annum of the net asset value of the fund) and a performance fee (typically, 20% of the
                                increase in the fund's net asset value during a year). Hedge funds have existed for many
                                decades and have become increasingly popular. They have now grown to be a substantial
                                portion of the asset management industry, with assets totaling around $3.8 trillion as
                                of 2021.[7] Hedge fund managers can have several billion dollars of assets under
                                management (AUM).
Hedge fund strategies are generally classified among four major categories: global
                                macro, directional, event-driven, and relative value (arbitrage). Strategies within
                                these categories each entail characteristic risk and return profiles. A fund may employ
                                a single strategy or multiple strategies for flexibility, risk management, or
                                diversification. The hedge fund's prospectus, also known as an offering memorandum,
                                offers potential investors information about key aspects of the fund, including the
                                fund's investment strategy, investment type, and leverage limit.
The elements contributing to a hedge fund strategy include the hedge fund's approach to
                                the market, the particular instrument use, the market sector the fund specializes in
                                (e.g., healthcare), the method used to select investments, and the amount of
                                diversification within the fund. There are a variety of market approaches to different
                                asset classes, including equity, fixed income, commodity, and currency. Instruments used
                                include equities, fixed income, futures, options, and swaps. Strategies can be divided
                                into those in which investments can be selected by managers, known as
                                'discretionary/qualitative', or those in which investments are selected using a
                                computerized system, known as 'systematic/quantitative'. The amount of diversification
                                within the fund can vary; funds may be multi-strategy, multi-fund, multi-market,
                                multi-manager, or a combination.
Sometimes hedge fund strategies are described as 'absolute return' and are classified
                                as either 'market neutral' or 'directional'. Market neutral funds have less correlation
                                to overall market performance by 'neutralizing' the effect of market swings whereas
                                directional funds utilize trends and inconsistencies in the market and have greater
                                exposure to the market's fluctuations.
