Investments in derivatives are counted toward the Fund&#x2019;s 80% policy to the extent that they provide investment exposure to the securities included within that policy or to one or more market risk factors associated with such securities. BlackRock considers an emerging market country to include any country that is: (1) generally recognized to be an emerging market country by the international financial community, including the World Bank; (2) classified by the United Nations as a developing country; or (3) included in the MSCI Emerging Markets Index (the &#x201c;MSCI EM Index&#x201d;). BlackRock determines that an investment is tied economically to an emerging market if such investment satisfies one or more of the following conditions: (1) the issuer&#x2019;s primary trading market is in an emerging market; (2) the issuer is organized under the laws of, derives at least 50% of its revenue from, or has at least 50% of its assets in emerging markets; and (3) the investment is included in an index representative of emerging markets. Equity securities include common stock, preferred stock and depositary receipts. Generally, the Fund will invest in equities or other financial instruments that are components of, or have characteristics similar to, the securities included in the MSCI EM Index. The MSCI EM Index is a capitalization-weighted index from a broad range of industries chosen for market size, liquidity and industry group representation. The Fund primarily seeks to buy common stock and may also invest in preferred stock. From time to time, the Fund may invest in shares of companies through &#x201c;new issues&#x201d; or initial public offerings (&#x201c;IPOs&#x201d;). The Fund may also purchase convertible securities. The Fund may use derivatives, including options, futures, swaps (including, but not limited to, total return swaps, some of which may be referred to as contracts for difference) and forward contracts, both to seek to increase the return of the Fund and to hedge (or protect) the value of its assets against adverse movements in currency exchange rates, interest rates and movements in the securities markets. In order to manage cash flows into or out of the Fund effectively, the Fund may buy and sell financial futures contracts or options on such contracts. Derivatives are financial instruments whose value is derived from another security, a currency or an index, including but not limited to the MSCI EM Index. The use of options, futures, swaps (including, but not limited to, total return swaps, some of which may be referred to as contracts for difference) and forward contracts can be effective in protecting or enhancing the value of the Fund&#x2019;s assets.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 6pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;The Fund seeks to pursue its investment objective by investing in equity securities in a disciplined manner, by using &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;proprietary return forecast models that incorporate quantitative analysis.

Performance for the periods prior to June 12, 2017 shown below is based on the investment process and investment strategies utilized by the Fund at that time under the name &#x201c;BlackRock Emerging Markets Long/Short Equity Fund.&#x201d;&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 6pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;The information shows you how the Fund&#x2019;s performance has varied year by year and provides some indication of the risks of investing in the Fund. The table compares the Fund&#x2019;s performance to that of the MSCI EM Index (Net). To the extent that dividends and distributions have been paid by the Fund, the performance information of the Fund in the chart and table assumes reinvestment of the dividends and distributions. As with all such investments, past performance (before and after taxes) is not an indication of future results. Sales charges are not reflected in the bar chart. If they were, returns would be less than those shown. However, the table includes all applicable fees and sales charges. If BlackRock and its affiliates had not waived or reimbursed certain Fund expenses during these periods, the Fund&#x2019;s returns would have been lower. Updated information on the Fund&#x2019;s performance, including its current net asset value, can be obtained by visiting www.blackrock.com or can be obtained by phone at (800) 882-0052.&lt;/span&gt;&lt;/div&gt; </oef:PerformanceNarrativeTextBlock>

Investments in derivatives are counted toward the Fund&#x2019;s 80% policy to the extent that they provide investment exposure to the securities included within that policy or to one or more market risk factors associated with such securities. BlackRock considers an emerging market country to include any country that is: (1) generally recognized to be an emerging market country by the international financial community, including the World Bank; (2) classified by the United Nations as a developing country; or (3) included in the MSCI Emerging Markets Index (the &#x201c;MSCI EM Index&#x201d;). BlackRock determines that an investment is tied economically to an emerging market if such investment satisfies one or more of the following conditions: (1) the issuer&#x2019;s primary trading market is in an emerging market; (2) the issuer is organized under the laws of, derives at least 50% of its revenue from, or has at least 50% of its assets in emerging markets; and (3) the investment is included in an index representative of emerging markets. Equity securities include common stock, preferred stock and depositary receipts. Generally, the Fund will invest in equities or other financial instruments that are components of, or have characteristics similar to, the securities included in the MSCI EM Index. The MSCI EM Index is a capitalization-weighted index from a broad range of industries chosen for market size, liquidity and industry group representation. The Fund primarily seeks to buy common stock and may also invest in preferred stock. From time to time, the Fund may invest in shares of companies through &#x201c;new issues&#x201d; or initial public offerings (&#x201c;IPOs&#x201d;). The Fund may also purchase convertible securities. The Fund may use derivatives, including options, futures, swaps (including, but not limited to, total return swaps, some of which may be referred to as contracts for difference) and forward contracts, both to seek to increase the return of the Fund and to hedge (or protect) the value of its assets against adverse movements in currency exchange rates, interest rates and movements in the securities markets. In order to manage cash flows into or out of the Fund effectively, the Fund may buy and sell financial futures contracts or options on such contracts. Derivatives are financial instruments whose value is derived from another security, a currency or an index, including but not limited to the MSCI EM Index. The use of options, futures, swaps (including, but not limited to, total return swaps, some of which may be referred to as contracts for difference) and forward contracts can be effective in protecting or enhancing the value of the Fund&#x2019;s assets. &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 6pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;The Fund seeks to pursue its investment objective by investing in equity securities in a disciplined manner, by using proprietary return forecast models that incorporate quantitative analysis. These forecast models are designed to identify aspects of mispricing across stocks which the Fund can seek to capture by over- and under-weighting particular equities while seeking to control incremental risk. &lt;/span&gt;&lt;/div&gt; </oef:StrategyNarrativeTextBlock>

Class K Shares commenced operations on January 25, 2018. As a result, the returns in the chart and the table shown below for Class K Shares prior to January 25, 2018 are those of the Fund&#x2019;s Institutional Shares, which are not offered in this prospectus. The performance of Class K Shares would be substantially similar to Institutional Shares because Class K Shares and Institutional Shares are invested in the same portfolio of securities and performance would differ only to the extent that Institutional Shares and Class K Shares have different expenses. The actual returns of Class K Shares would have been higher than those of the Institutional Shares because Class K Shares have lower expenses than the Institutional Shares. The table compares the Fund&#x2019;s performance to that of the MSCI EM Index (Net). To the extent that dividends and distributions have been paid by the Fund, the performance information of the Fund in the chart and table assumes reinvestment of the dividends and distributions. As with all such investments, past performance (before and after taxes) is not an indication of future results. The table includes all applicable fees. If BlackRock and its affiliates had not waived or reimbursed certain Fund expenses during these &lt;/span&gt;&lt;/div&gt;  &lt;div style="line-height: 10.695pt; text-align: left;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;periods, the Fund&#x2019;s returns would have been lower.
