Investment Objective

The AQR Long-Short Equity Fund (the “Fund”) seeks capital appreciation.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

	Class R6
Management Fee	1.10%
Distribution (12b-1) Fee	None
Other Expenses
Dividends on short sales1	0.75%
All other expenses	0.07%
Total Other Expenses	0.82%
Acquired Fund Fees and Expenses2	0.10%
Total Annual Fund Operating Expenses3	2.02%

1	When a cash dividend is declared on a stock the Fund has sold short, the Fund is required to pay an amount equal to the dividend to the party from which the Fund has borrowed the stock, and to record the payment as an expense.

2	Acquired Fund Fees and Expenses reflect the expenses incurred indirectly by the Fund as a result of the Fund's investments in underlying money market mutual funds, exchange-traded funds or other pooled investment vehicles.

3	Total Annual Fund Operating Expenses are 1.27% for Class R6 Shares if dividends on short sales are not included.

Example: This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

	1 Year	3 Years	5 Years	10 Years
Class R6 Shares	$205	$634	$1,088	$2,348

AQR Funds–Summary Prospectus2

Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 249% of the average value of its portfolio.

Principal Investment Strategies of the Fund

The Fund seeks to provide investors with three different sources of return: 1) the potential gains from its long-short equity positions, 2) overall exposure to equity markets, and 3) the tactical variation of its net exposure to equity markets. The Fund seeks to provide higher risk-adjusted returns with lower volatility compared to global equity markets.

Under normal market conditions, the Fund pursues its investment objective by investing at least 80% of its net assets (including borrowings for investment purposes) in equity instruments and equity related and/or derivative instruments. Equity instruments include common stock, preferred stock, and depositary receipts (“Equity Instruments”). Equity related and/or derivative instruments are investments that provide exposure to the performance of equity instruments, including equity swaps (both single-name and index swaps), equity index futures and exchange-traded funds and similar pooled investment vehicles (collectively, “Equity Derivative Instruments” and together with Equity Instruments, “Instruments”).

In managing the Fund, the Adviser takes long positions in those Instruments that, based on proprietary quantitative models, the Adviser forecasts to be undervalued and likely to increase in price, and takes short positions in those Instruments that the Adviser forecasts to be overvalued and likely to decrease in price.

The Fund may invest in or have exposure to companies of any size. The Fund has no geographic limits on where it may invest. The Fund will generally invest in instruments of companies located in global developed markets, including the United States. As of the date of this prospectus, the Adviser considers global developed markets to be those countries included in the MSCI World Index. The Fund does not limit its investments to any one country, and may invest in any one country without limit.

The Adviser uses a set of value, momentum, quality and other economic indicators to generate an investment portfolio based on the Adviser’s global security selection and asset allocation models.

•	Value indicators identify investments that appear cheap based on fundamental measures, often as a result of lack of favor. Examples of value indicators include using price-to-earnings and price-to-book ratios for choosing individual equities.
•	Momentum indicators identify investments with strong recent performance. Examples of momentum indicators include simple price momentum for choosing individual equities.
•	Quality indicators identify stable companies in good business health, including those with strong profitability and stable earnings.
•	In addition to these three main indicators, the Adviser may use a number of additional quantitative indicators based on the Adviser’s proprietary research. The Adviser may add or modify the economic indicators employed in selecting portfolio holdings from time to time.

Applying these indicators, the Adviser may take long or short positions in sectors, industries and companies that it believes are attractive or unattractive. In the aggregate the Fund expects to have net long exposure to the equity markets, which the Adviser may adjust over time. When the Adviser determines that market conditions are unfavorable, the Fund may reduce its long market exposure. Similarly, when the Adviser determines that market conditions are favorable, the Fund may increase its long market exposure.

The Fund is not designed to be market-neutral. The Adviser will use a tactical allocation overlay to manage the Fund’s beta exposure to broad global markets through the use of equity swaps, equity index futures and foreign currency forwards. The Adviser, on average, intends to target a portfolio beta of 0.5. The Adviser expects that the Fund’s target beta will typically range from 0.3 to 0.7.

The Fund may, but is not required to, hedge exposure to foreign currencies using foreign currency forwards or futures.

The Fund, when taking a “long” equity position, will purchase a security that will benefit from an increase in the price of that security. When taking a “short” equity position, the Fund borrows the security from a third party and sells it at the then current market price. A “short” equity position will benefit from a decrease in price of the security and will lose value if the price of the security increases. Similarly, the Fund may also take “long” and “short” positions in an Equity Derivative Instrument. A “long” position in an Equity Derivative Instrument will benefit from an increase in the price of the underlying instrument. A “short” position in an Equity Derivative Instrument will benefit from a decrease in price of the underlying instrument and will lose value if the price of the underlying instrument increases. Simultaneously engaging in long investing and short selling is designed to reduce the net exposure of the overall portfolio to general market movements.

AQR Funds–Summary Prospectus3

The Fund may use Equity Derivative Instruments and foreign currency forwards as a substitute for investing in conventional securities and for investment purposes to increase its economic exposure to a particular security, index or currency in a cost-effective manner. At times, the Fund may gain all equity or currency exposure through the use of Equity Derivative Instruments and currency derivative instruments, and may invest in such instruments without limitation. The Fund’s use of Equity Derivative Instruments and currency derivative instruments will have the economic effect of financial leverage. Financial leverage magnifies exposure to the swings in prices of an asset underlying an Equity Derivative Instrument or currency derivative instrument and results in increased volatility, which means the Fund will have the potential for greater gains, as well as the potential for greater losses, than if the Fund does not use Equity Derivative Instruments and currency derivative instruments that have a leveraging effect. Leveraging tends to magnify, sometimes significantly, the effect of any increase or decrease in the Fund’s exposure to an asset and may cause the Fund’s NAV to experience greater volatility. For example, if the Adviser seeks to gain enhanced exposure to a specific asset through an Equity Derivative Instrument providing leveraged exposure to the asset and that Equity Derivative Instrument increases in value, the gain to the Fund will be magnified; however, if that investment decreases in value, the loss to the Fund will be magnified. A decline in the Fund’s assets due to losses magnified by the Equity Derivative Instruments providing leveraged exposure may require the Fund to liquidate portfolio positions to satisfy its obligations, to meet redemption requests or to meet asset segregation requirements when it may not be advantageous to do so. There is no assurance that the Fund’s use of Equity Derivative Instruments providing enhanced exposure will enable the Fund to achieve its investment objective.

A significant portion of the Fund’s assets may be held in cash or cash equivalents including, but not limited to, money market instruments, U.S. treasury bills, interests in short-term investment funds or shares of money market or short-term bond funds. These cash or cash equivalent holdings serve as collateral for the positions the Fund takes and also earn income for the Fund.

When taking into account derivative instruments and instruments with a maturity of one year or less at the time of acquisition, the Fund is expected to have annual turnover of approximately 250% to 500%, although actual portfolio turnover may be higher or lower and will be affected by market conditions. This estimated annual portfolio turnover rate is based on the expected regular turnover resulting from the Fund’s implementation of its investment strategy, and does not take into account turnover that may occur as a result of purchases and redemptions into and out of the Fund’s portfolio.

Principal Risks of Investing in the Fund

Risk is inherent in all investing. The value of your investment in the Fund, as well as the amount of return you receive on your investment, may fluctuate significantly from day to day and over time. You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments. The Fund is not a complete investment program and should be considered only as one part of an investment portfolio. The Fund is more appropriate for long-term investors who can bear the risk of short-term NAV fluctuations, which at times, may be significant and rapid, however, all investments long- or short-term are subject to risk of loss. The following is a summary description of certain risks of investing in the Fund.

Common Stock Risk: The Fund may invest in, or have exposure to, common stocks. Common stocks are subject to greater fluctuations in market value than certain other asset classes as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Counterparty Risk: The Fund may enter into various types of derivative contracts. Many of these derivative contracts will be privately negotiated in the over-the-counter market. These contracts also involve exposure to credit risk, since contract performance depends in part on the financial condition of the counterparty. If a privately negotiated over-the-counter contract calls for payments by the Fund, the Fund must be prepared to make such payments when due. In addition, if a counterparty’s creditworthiness declines, the Fund may not receive payments owed under the contract, or such payments may be delayed under such circumstances and the value of agreements with such counterparty can be expected to decline, potentially resulting in losses to the Fund.

Credit Risk: Credit risk refers to the possibility that the issuer of a security or the issuer of the reference asset of a derivative instrument will not be able to make principal and interest payments when due. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also affect the value of the Fund’s investment in that issuer. Securities rated in the four highest categories by the rating agencies are considered investment grade but they may also have some speculative characteristics. Investment grade ratings do not guarantee that the issuer will not default on its payment obligations or that bonds will not otherwise lose value.

Currency Risk: Currency risk is the risk that changes in currency exchange rates will negatively affect securities denominated in, and/or receiving revenues in, foreign currencies. The liquidity and trading value of foreign currencies could be affected by global economic factors, such as inflation, interest rate levels, and trade balances among countries, as well as the actions of sovereign governments and central banks. Adverse changes in currency exchange rates (relative to the U.S. dollar) may erode or reverse any potential gains from the Fund’s investments in securities denominated in a foreign currency or may widen existing losses.

AQR Funds–Summary Prospectus4

Derivatives Risk: In general, a derivative instrument typically involves leverage, i.e., it provides exposure to potential gain or loss from a change in the level of the market price of the underlying security or currency (or a basket or index) in a notional amount that exceeds the amount of cash or assets required to establish or maintain the derivative instrument. Adverse changes in the value or level of the underlying asset or index, which the Fund may not directly own, can result in a loss to the Fund substantially greater than the amount invested in the derivative itself. The use of derivative instruments also exposes the Fund to additional risks and transaction costs. These instruments come in many varieties and have a wide range of potential risks and rewards, and may include, as further described in the section entitled “Principal Investment Strategies of the Fund,” futures contracts, forward contracts and swaps. A risk of the Fund’s use of derivatives is that the fluctuations in their values may not correlate perfectly with the overall securities markets. Additionally, to the extent the Fund is required to segregate or “set aside” (often referred to as “asset segregation”) liquid assets or otherwise cover open positions with respect to certain derivative instruments, the Fund may be required to sell portfolio instruments to meet these asset segregation requirements. There is a possibility that segregation involving a large percentage of the Fund’s assets could impede portfolio management or the Fund’s ability to meet redemption requests or other current obligations.

Foreign Investments Risk: Foreign investments often involve special risks not present in U.S. investments that can increase the chances that the Fund will lose money. These risks include:

•	The Fund generally holds its foreign instruments and cash in foreign banks and securities depositories, which may be recently organized or new to the foreign custody business and may be subject to only limited or no regulatory oversight.
•	Changes in foreign currency exchange rates can affect the value of the Fund’s portfolio.
•	The economies of certain foreign markets may not compare favorably with the economy of the United States with respect to such issues as growth of gross national product, reinvestment of capital, resources and balance of payments position.
•	The governments of certain countries may prohibit or impose substantial restrictions on foreign investments in their capital markets or in certain industries.
•	Many foreign governments do not supervise and regulate stock exchanges, brokers and the sale of securities to the same extent as does the United States and may not have laws to protect investors that are comparable to U.S. securities laws.
•	Settlement and clearance procedures in certain foreign markets may result in delays in payment for or delivery of securities not typically associated with settlement and clearance of U.S. investments.

Forward and Futures Contract Risk: The successful use of forward and futures contracts draws upon the Adviser’s  skill and experience with respect to such instruments and are subject to special risk considerations. The primary risks associated with the use of forward and futures contracts, which may adversely affect the Fund’s NAV and total return, are (a) the imperfect correlation between the change in market value of the instruments held by the Fund and the price of the forward or futures contract; (b) possible lack of a liquid secondary market for a forward or futures contract and the resulting inability to close a forward or futures contract when desired; (c) losses caused by unanticipated market movements, which are potentially unlimited; (d) the Adviser’s  inability to predict correctly the direction of securities prices, interest rates, currency exchange rates and other economic factors; (e) the possibility that the counterparty will default in the performance of its obligations; and (f) if the Fund has insufficient cash, it may have to sell securities from its portfolio to meet daily variation margin requirements, and the Fund may have to sell securities at a time when it may be disadvantageous to do so.

Hedging Transactions Risk: The Adviser  from time to time employs various hedging techniques. The success of the Fund’s hedging strategy will be subject to the Adviser’s ability to correctly assess the degree of correlation between the performance of the instruments used in the hedging strategy and the performance of the investments in the portfolio being hedged. Since the characteristics of many securities change as markets change or time passes, the success of the Fund’s hedging strategy will also be subject to the Adviser’s ability to continually recalculate, readjust, and execute hedges in an efficient and timely manner. For a variety of reasons, the Adviser  may not seek to establish a perfect correlation between such hedging instruments and the portfolio holdings being hedged. Such imperfect correlation may prevent the Fund from achieving the intended hedge or expose the Fund to risk of loss. In addition, it is not possible to hedge fully or perfectly against any risk, and hedging entails its own costs (such as trading commissions and fees).

High Portfolio Turnover Risk: The investment techniques and strategies utilized by the Fund, including investments made on a shorter-term basis or in derivative instruments or instruments with a maturity of one year or less at the time of acquisition, may result in frequent portfolio trading and high portfolio turnover. High portfolio turnover rates will cause the Fund to incur higher levels of brokerage fees and commissions, which may reduce performance, and may cause higher levels of current tax liability to shareholders in the Fund.

Investment in Other Investment Companies Risk: As with other investments, investments in other investment companies, including exchange-traded funds (“ETFs”), are subject to market and manager risk. In addition, if the Fund acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Fund (including management and advisory fees) and, indirectly, the expenses of the investment companies. The Fund may invest in money market mutual funds. An investment in a money market mutual fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although money market mutual funds that invest in U.S. government securities seek to preserve the value of the Fund’s investment at $1.00 per share, it is possible to lose money by investing in a stable

AQR Funds–Summary Prospectus5

NAV money market mutual fund. Moreover, recent SEC rule amendments require prime money market mutual funds to use floating NAVs that do not preserve the value of the Fund’s investment at $1.00 per share. These rule amendments may impact the Fund’s use of prime money market mutual funds for capital preservation purposes.

Leverage Risk: As part of the Fund’s principal investment strategy, the Fund will make investments in futures contracts, forward contracts, swaps and other derivative instruments. These derivative instruments provide the economic effect of financial leverage by creating additional investment exposure to the underlying instrument, as well as the potential for greater loss. If the Fund uses leverage through activities such as entering into short sales or purchasing derivative instruments, the Fund has the risk that losses may exceed the net assets of the Fund. The net asset value of the Fund while employing leverage will be more volatile and sensitive to market movements.

Manager Risk: If the Adviser makes poor investment decisions, it will negatively affect the Fund’s investment performance.

Market Risk: Market risk is the risk that the markets on which the Fund’s investments trade will increase or decrease in value. Prices may fluctuate widely over short or extended periods in response to company, market or economic news. Markets also tend to move in cycles, with periods of rising and falling prices. If there is a general decline in the securities and other markets, your investment in the Fund may lose value, regardless of the individual results of the securities and other instruments in which the Fund invests.

Mid-Cap Securities Risk: The Fund may invest in, or have exposure to, the securities of mid-cap companies. The prices of securities of mid-cap companies generally are more volatile than those of large capitalization companies and are more likely to be adversely affected than large-cap companies by changes in earnings results and investor expectations or poor economic or market conditions, including those experienced during a recession.

Model and Data Risk: Given the complexity of the investments and strategies of the Fund, the Adviser relies heavily on quantitative models and information and data supplied by third parties (“Models and Data”). Models and Data are used to construct sets of transactions and investments, to provide risk management insights, and to assist in hedging the Fund’s investments.

When Models and Data prove to be incorrect or incomplete, any decisions made in reliance thereon expose the Fund to potential risks. Similarly, any hedging based on faulty Models and Data may prove to be unsuccessful. Some of the models used by the Adviser for the Fund are predictive in nature. The use of predictive models has inherent risks. Because predictive models are usually constructed based on historical data supplied by third parties, the success of relying on such models may depend heavily on the accuracy and reliability of the supplied historical data. The Fund bears the risk that the quantitative models used by the Adviser will not be successful in forecasting movements in industries, sectors or companies or in determining the weighting of investment positions that will enable the Fund to achieve its investment objectives.

All models rely on correct data inputs. If incorrect market data is entered into even a well-founded model, the resulting information will be incorrect. However, even if market data is input correctly, “model prices” will often differ substantially from market prices, especially for instruments with complex characteristics, such as derivative instruments.

Momentum Style Risk: Investing in or having exposure to securities with positive momentum entails investing in securities that have had above-average recent returns. These securities may be more volatile than a broad cross-section of securities. In addition, there may be periods during which the investment performance of the Fund while using a momentum strategy may suffer.

Short Sale Risk: The Fund enters into a short sale by selling a security it has borrowed (typically from a broker or other institution). If the market price of a security increases after the Fund borrows the security, the Fund will suffer a (potentially unlimited) loss when it replaces the borrowed security at the higher price. In certain cases, purchasing a security to cover a short position can itself cause the price of the security to rise further, thereby exacerbating the loss. In addition, the Fund may not always be able to borrow the security at a particular time or at an acceptable price. The Fund may also take a short position in a derivative instrument, such as a future, forward or swap. A short position in a derivative instrument involves the risk of a theoretically unlimited increase in the value of the underlying instrument, which could cause the Fund to suffer a (potentially unlimited) loss. Short sales also involve transaction and financing costs that will reduce potential Fund gains and increase potential Fund losses.

Small-Cap Securities Risk: Investments in or exposure to the securities of companies with smaller market capitalizations involve higher risks in some respects than do investments in securities of larger companies. For example, prices of such securities are often more volatile than prices of large capitalization securities. In addition, due to thin trading in some such securities, an investment in these securities may be more illiquid (i.e., harder to sell) than that of larger capitalization securities. Smaller capitalization companies also fail more often than larger companies and may have more limited management and financial resources than larger companies.

AQR Funds–Summary Prospectus6

Swap Agreements Risk: Swap agreements involve the risk that the party with whom the Fund has entered into the swap will default on its obligation to pay the Fund. Additionally, certain unexpected market events or significant adverse market movements could result in the Fund not holding enough assets to be able to meet its obligations under the agreement. Such occurrences may negatively impact the Fund’s ability to implement its principal investment strategies and could result in losses to the Fund.

Value Style Risk: Investing in or having exposure to “value” securities, as described in the section titled “Principal Investment Strategies of the Fund,” presents the risk that the securities may never reach what the Adviser believes are their full market values, either because the market fails to recognize what the Adviser considers to be the security’s true value or because the Adviser misjudged that value. In addition, there may be periods during which the investment performance of the Fund while using a value strategy may suffer.
