A hedge fund is an investment fund that pools capital from a limited number of sophisticated individual or institutional investors and invests in a variety of assets, often with complex portfolio construction and risk management techniques.〔 It is administered by a professional management firm, and often structured as a limited partnership, limited liability company, or similar vehicle. Hedge funds are generally distinct from mutual funds as their use of leverage is not capped by regulators and distinct from private equity funds as the majority of hedge funds invest in relatively liquid assets. The name "hedge fund" originated from the paired long and short positions that the first of these funds used to hedge market risk. Over time the types and nature of the hedging concepts expanded, as did the different types of investment vehicles. Today, hedge funds engage in a diverse range of markets and strategies and employ a wide variety of financial instruments and risk management techniques.〔 Hedge funds are made available only to certain sophisticated or accredited investors and cannot be offered or sold to the general public.〔 As such, they generally avoid direct regulatory oversight, bypass licensing requirements applicable to investment companies, and operate with greater flexibility than mutual funds and other investment funds. However, regulations passed in the United States and Europe after the financial crisis of 2007–08 were intended to increase government oversight of hedge funds and eliminate certain regulatory gaps. While hedge funds have existed for many decades, they have become increasingly popular in recent years, growing to be one of the world's largest asset management classes.〔Lemke, Lins, Hoenig & Rube, ''Hedge Funds and Other Private Funds: Regulation and Compliance'' (Thomson West, 2014 ed.).〕 Hedge funds are most often open-ended and allow additions or withdrawals by their investors (generally on a monthly or quarterly basis).〔 A hedge fund's value is calculated as a share of the fund's net asset value, meaning that increases and decreases in the value of the fund's investment assets (and fund expenses) are directly reflected in the amount an investor can later withdraw. Many hedge fund investment strategies aim to achieve a positive return on investment regardless of whether markets are rising or falling ("absolute return"). Hedge fund managers often invest money of their own in the fund they manage, which serves to align their own interests with those of the investors in the fund. A hedge fund typically pays its investment manager an annual management fee (for example 1% of the assets of the fund), and a performance fee (for example 20% of the increase in the fund's net asset value during the year).〔 Some hedge funds have several billion dollars of assets under management (AUM). , hedge funds represented 1.1% of the total funds and assets held by financial institutions. As of June 2013, the estimated size of the global hedge fund industry was US$2.4 trillion. ==Etymology== The word "hedge", meaning a line of bushes around a field, has long been used as a metaphor for the placing of limits on risk. Early hedge funds sought to hedge specific investments against general market fluctuations by shorting the market, hence the name. Nowadays, however, many different investment strategies are used, many of which do not "hedge risk".〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「hedge fund」の詳細全文を読む スポンサード リンク
