FOREIGN SECURITIES RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]
FOREIGN SECURITIES RISK is the risk that investing in foreign (non‑U.S.) securities may result in the Fund experiencing more rapid and extreme changes in value than a fund that invests exclusively in securities of U.S. companies, due to less liquid markets and adverse economic, political, diplomatic, financial, and regulatory factors. Foreign governments may impose limitations on foreigners’ ownership of interests in local issuers, restrictions on the ability to repatriate assets, and may also impose taxes. Any of these events could cause the value of the Fund’s investments to decline. Foreign banks, agents and securities depositories that hold the Fund’s foreign assets may be subject to little or no regulatory oversight over, or independent evaluation, of their operations. Additional costs associated with investments in foreign securities may include higher custodial fees than those applicable to domestic custodial arrangements and transaction costs of foreign currency conversions. Unless the Fund has hedged its foreign currency exposure, foreign securities risk also involves the risk of negative foreign currency rate fluctuations, which may cause the value of securities denominated in such foreign currency (or other instruments through which the Fund has exposure to foreign currencies) to decline in value. Currency exchange rates may fluctuate significantly over short periods of time. Currency hedging strategies, if used, are not always successful. For instance, forward foreign currency exchange contracts, if used by the Fund, could reduce performance if there are unanticipated changes in currency exchange rates.
EMERGING MARKETS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]
EMERGING MARKETS RISK is the risk that emerging markets are generally subject to greater market volatility, political, social and economic instability, uncertain trading markets and more governmental limitations on foreign investments than more developed markets. In addition, companies operating in emerging markets may be subject to lower trading volumes and greater price volatility than companies in more developed markets. Emerging market economies may be based on only a few industries, may be highly vulnerable to changes in local and global trade conditions, and may suffer from extreme and volatile debt burdens or inflation rates. Companies in emerging market countries generally may be subject to less stringent regulatory, disclosure, financial reporting, accounting, auditing and recordkeeping standards than companies in more
developed countries. As a result, information, including financial information, about such companies may be less available and reliable, which can impede the Fund’s ability to evaluate such companies. Securities law and the enforcement of systems of taxation in many emerging market countries may change quickly and unpredictably, and the ability to bring and enforce actions (including bankruptcy, confiscatory taxation, expropriation, nationalization of a company’s assets, restrictions on foreign ownership of local companies,
restrictions on withdrawing assets from the country, protectionist measures and practices such as share blocking), or to obtain information needed to pursue or enforce such actions, may be limited. Investments in emerging market securities may be subject to additional transaction costs, delays in settlement procedures, unexpected market closures, and lack of timely information.
MANAGEMENT RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]
MANAGEMENT RISK is the risk that a strategy used by the Fund’s investment adviser may fail to produce the intended results or that imperfections, errors or limitations in the tools and data used by the investment adviser may cause unintended results.
VALUATION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]
VALUATION RISK is the risk that the sale price the Fund could receive for a portfolio security may differ from the Fund’s valuation of the security, particularly for securities that trade in low volume or volatile markets or that are valued using a fair value methodology. It is possible that the Fund could incur a loss because a portfolio security is sold at a discount to the value ascribed to it for purposes of calculating the Fund’s net asset value. Fair value methodologies may involve more subjectivity than the use of market quotations when fair valuing an investment. In addition, the value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares.
SECURITIES LENDING RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]
SECURITIES LENDING RISK is the risk that the Fund may lose money because the borrower of the loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of collateral provided for loaned securities or a decline in the value of any investments made with cash collateral.
DERIVATIVES RISKS [Member]  
Prospectus [Line Items]  
Risk [Text Block]
DERIVATIVES RISK is the risk that derivatives may pose risks in addition to and greater than those associated with investing directly in securities, currencies and other instruments, may be illiquid or less liquid, more volatile, more difficult to value and leveraged so that small changes in the value of the underlying instrument may produce disproportionate losses to the Fund. Derivatives are also subject to counterparty risk, which is the risk that the other party to the transaction will not perform its contractual obligations. The use of derivatives is a highly specialized activity that involves investment techniques and
risks different from those associated with investments in more traditional securities and instruments.
 
   
FUTURES CONTRACTS RISK is the risk that there will be imperfect correlation between the change in market value of the Fund’s securities and the price of futures contracts, which may result in the strategy not working as intended; the possible inability of the Fund to sell or close out a futures contract at the desired time or price; losses due to unanticipated market movements, which potentially are unlimited; and the possible inability of the Fund’s investment adviser to correctly predict the direction of securities’ prices, interest rates, currency exchange rates and other economic factors, which may make the Fund’s returns more volatile or increase the risk of loss.
GEOGRAPHIC RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]
GEOGRAPHIC RISK is the risk that if the Fund invests a significant portion of its total assets in certain issuers within the same country or geographic region, an adverse economic, business or political development affecting that country or region may affect the value of the Fund’s investments more, and the Fund’s investments may be more volatile, than if its investments were not so concentrated in such country or region.
 
   
JAPAN INVESTMENT RISK is the risk of investing in securities of Japanese issuers. The Japanese economy may be subject to considerable degrees of economic, political and social instability, which could negatively impact Japanese issuers. In recent times, Japan’s economic growth rate has remained low, and it may remain low in the future. In addition, Japan is subject to the risk of natural disasters, such as earthquakes, volcanic eruptions, typhoons and tsunamis, which could negatively affect the securities of Japanese companies held by the Fund.
 
   
EUROPEAN INVESTMENT RISK is the risk that investments in certain countries in the European Union (the “EU”) are susceptible to high political, social, or economic risks due to restrictions on inflation rates, rising debt levels and fiscal and monetary controls. Decreasing imports or exports, changes in local or EU regulations on trade, changes in the exchange rate of the euro, the default or threat of default by an EU member country on its sovereign debt, budget deficits and recessions in an EU member country may have significant adverse effects on the economies of the other EU member countries. Separately, the EU faces issues involving its membership, structure, procedures and policies. The exit of one or more member states from the EU would likely place the EU’s currency and banking system in jeopardy and result in increased volatility, illiquidity and potentially lower economic growth in the affected markets, which will adversely affect the Fund’s EU investments.
SECTOR RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]
SECTOR RISK is the risk that companies in similar businesses may be similarly affected by particular economic or market events, which may, in certain circumstances, cause the value of securities of all companies in a particular sector of the market to decrease.
 
   
FINANCIALS SECTOR RISK is the risk that companies in the financials sector can be significantly affected by changes in interest rates, government regulation, the rate of corporate and consumer debt defaulted, price competition, and the availability and cost of capital, among other factors.
 
   
INDUSTRIALS SECTOR RISK is the risk that companies in the industrials sector may be significantly affected by, among other things, worldwide economic growth, supply and demand for specific products and services, rapid technological developments, international political and economic developments, environmental issues, and tax and governmental regulatory policies.
MARKET RISKS [Member]  
Prospectus [Line Items]  
Risk [Text Block]
MARKET RISK is the risk that the value of the Fund’s investments may increase or decrease in response to expected, real or perceived economic, political or financial events in the U.S. or global markets. The frequency and magnitude of such changes in value cannot be predicted. Certain securities and other investments held by the Fund may experience increased volatility, illiquidity, or other potentially adverse effects in response to changing market conditions, inflation, elevated levels of government debt, changes in interest rates, lack of liquidity in the bond or equity markets or volatility in the equity markets. Market disruptions caused by local or regional events such as financial institution failures, changes in trade regulation or economic sanctions, internal unrest and discord, war, acts of terrorism, the spread of infectious illness (including epidemics and pandemics) or other public health issues, recessions, the threat or occurrence of a government shutdown, or other events or adverse investor sentiment could have a significant impact on the Fund and its investments. During periods of market disruption or other abnormal market conditions, the Fund’s exposure to risks described elsewhere in this summary will likely increase.
INVESTMENT STYLE RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]
INVESTMENT STYLE RISK is the risk that different investment styles (e.g., “growth”, “value” or “quantitative”) tend to shift in and out of favor, depending on market and economic conditions as well as investor sentiment. The Fund may outperform or underperform other funds that invest in similar asset classes but employ a different investment style. The Fund may also employ a combination of styles that impacts its risk characteristics.
 
   
QUANTITATIVE INVESTING RISK is the risk that the value of securities or other investments selected using quantitative analysis can perform differently from the market as a whole or from their expected performance and the Fund may realize a loss. This may be as a result of the factors used in building a multifactor quantitative model, the weights placed on each factor, the accuracy of historical data utilized, and changing sources of market returns. Whenever a model is used, there is also a risk that the model will not work as planned.
MID CAP STOCK RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]
MID CAP STOCK RISK is the risk that stocks of mid‑sized companies may be more volatile than stocks of larger, more established companies, and may lack sufficient market liquidity. Mid‑sized companies may have limited product lines or financial resources, may be dependent upon a particular niche of the market, or may be dependent upon a small or inexperienced management group. Securities of mid‑sized companies may trade less frequently and in lower volume than the securities of larger companies, which could lead to higher transaction costs. Generally the smaller the company size, the greater the risk.
