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. In the United States, financial regulations require that hedge funds be marketed only to institutional investors and high-net-worth individuals.
Investment is traditionally defined as the "commitment of resources to achieve later benefits". If an investment involves money, then it can be defined as a "commitment of money to receive more money later". From a broader viewpoint, an investment can be defined as "to tailor the pattern of expenditure and receipt of resources to optimise the desirable patterns of these flows". When expenditures and receipts are defined in terms of money, then the net monetary receipt in a time period is termed cash flow, while money received in a series of several time periods is termed cash flow stream.
In finance, being short in an asset means investing in such a way that the investor will profit if the market value of the asset falls. This is the opposite of the more common long position, where the investor will profit if the market value of the asset rises. An investor that sells an asset short is, as to that asset, a short seller.
An exchange-traded fund (ETF) is a type of investment fund that is also an exchange-traded product, i.e., it is traded on stock exchanges. ETFs own financial assets such as stocks, bonds, currencies, debts, futures contracts, and/or commodities such as gold bars. The list of assets that each ETF owns, as well as their weightings, is posted on the website of the issuer daily, or quarterly in the case of active non-transparent ETFs. Many ETFs provide some level of diversification compared to owning an individual stock.

Long/short equity is an investment strategy generally associated with hedge funds. It involves buying equities that are expected to increase in value and selling short equities that are expected to decrease in value. This is different from the risk reversal strategies where investors will simultaneously buy a call option and sell a put option to simulate being long in a stock.
A private investment in public equity, often called a PIPE deal, involves the selling of publicly traded common shares or some form of preferred stock or convertible security to private investors. It is an allocation of shares in a public company not through a public offering in a stock exchange. PIPE deals are part of the primary market. In the U.S., a PIPE offering may be registered with the Securities and Exchange Commission on a registration statement or may be completed as an unregistered private placement.
A "fund of funds" (FOF) is an investment strategy of holding a portfolio of other investment funds rather than investing directly in stocks, bonds or other securities. This type of investing is often referred to as multi-manager investment. A fund of funds may be "fettered", meaning that it invests only in funds managed by the same investment company, or "unfettered", meaning that it can invest in external funds run by other managers.

In January 2021, a short squeeze of the stock of the American video game retailer GameStop and other securities took place, causing major financial consequences for certain hedge funds and large losses for short sellers. Approximately 140 percent of GameStop's public float had been sold short, and the rush to buy shares to cover those positions as the price rose caused it to rise even further. The short squeeze was initially and primarily triggered by users of the subreddit r/wallstreetbets, an Internet forum on the social news website Reddit, although a number of hedge funds also participated. At its height, on January 28, the short squeeze caused the retailer's stock price to reach a pre-market value of over US$500 per share, nearly 30 times the $17.25 valuation at the beginning of the month. The price of many other heavily shorted securities and cryptocurrencies also increased.
