Portfolio Turnover [Text Block]	rr_PortfolioTurnoverTextBlock	The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund 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 58% of the average value of its portfolio.

Expense Example [Heading]	rr_ExpenseExampleHeading	Example.
Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	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:
Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies of the Fund
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund invests, under normal circumstances, at least 80% of net assets (plus any borrowings for investment purposes) in securities of small- and/or mid-capitalization issuers. The Fund invests primarily in equity securities.             In complying with this 80% investment requirement, the Fund may include synthetic securities that have economic characteristics similar to the Fund’s direct investments that are counted toward the 80% investment requirement.             The Fund considers an issuer to be a small-capitalization issuer if it has a market capitalization, at the time of purchase, no larger than the largest capitalized issuer included in the Russell 2000® Index during the most recent 11-month period (based on month-end data) plus the most recent data during the current month. The Russell 2000® Index measures the performance of the 2,000 smallest issuers in the Russell 3000® Index, which measures the performance of the 3,000 largest U.S. issuers. The Russell 2000® Index is widely regarded as representative of small capitalization issuers. As of October 31, 2011, the capitalization of companies in the Russell 2000® Index range from $32 million to $3.7 billion.             The Fund considers an issuer to be a mid-capitalization issuer if it has a market capitalization, at the time of purchase, within the range of the largest and smallest capitalized issuers included in the Russell Midcap® Index during the most recent 11-month period (based on the month-end data) plus the most recent data during the current month. The Russell Midcap® Index measures the performance of the 800 smallest issuers in the Russell 1000® Index. The Russell 1000® Index measures the performance of the 1,000 largest issuers domiciled in the United States. The issuers in the Russell Midcap® Index represent approximately 25% of the total market capitalization of the Russell 1000® Index. As of October 31, 2011, the capitalization of companies in the Russell Midcap® Index range from $202 million to $19.3 billion.             The Fund invests, under normal circumstances, in issuers located in at least three countries, including the U.S.             The Fund will, under normal circumstances, maintain at least 20% of its total assets in U.S. dollar-denominated securities. The Fund emphasizes investment in issuers in developed countries such as the United States, the countries of Western Europe and certain countries in the Pacific Basin. As of October 31, 2011, the principal countries in which the Fund invested were the United States, the United Kingdom, Canada, Brazil and the Philippines. The Fund may also invest up to 35% of its total assets in issuers located in developing countries, i.e., those that are identified as in the initial stages of their industrial cycles.             The Fund invests primarily in equity securities of domestic and foreign issuers that are considered by the Fund’s portfolio managers to have strong earnings growth.             The Fund can invest in derivative instruments including forward foreign currency contracts and futures.             The Fund can utilize forward foreign currency contracts to mitigate the risk of foreign currency exposure. A forward foreign currency contract is an agreement between parties to exchange a specified amount of currency at a specified future time at a specified rate. Forward foreign currency contracts are used to protect against uncertainty in the level of future foreign currency exchange rates. The Fund can use these contracts to hedge against adverse movements in the foreign currencies in which portfolio securities are denominated.             The Fund can invest in futures contracts, including index futures, to seek exposure to certain asset classes. A futures contract is a standardized agreement between two parties to buy or sell a specific quantity of an underlying instrument at a specific price at a specific future time. The value of the futures contract tends to increase and decrease in tandem with the value of the underlying instrument. Futures contracts are bilateral agreements, with both the purchaser and the seller equally obligated to complete the transaction. Depending on the terms of the particular contract, futures contracts are settled through either physical delivery of the underlying instrument on the settlement date or by payment of a cash settlement amount on the settlement date.             The portfolio managers employ a disciplined investment strategy that emphasizes fundamental research, supported by quantitative analysis, portfolio construction and risk management techniques. The strategy primarily focuses on identifying issuers that have experienced, or exhibit the potential for, accelerating or above average earnings growth but whose prices do not fully reflect these attributes. Investments for the portfolio are selected bottom-up on a security-by-security basis. The focus is on the strengths of individual issuers, rather than sector or country trends.             The Fund’s portfolio managers may consider selling a security for several reasons, including when (1) its fundamentals deteriorate or it posts disappointing earnings, (2) its security price appears to be overvalued, or (3) a more attractive investment opportunity is identified.
Risk [Heading]	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	As with any mutual fund investment, loss of money is a risk of investing. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are:             Derivatives Risk. The performance of derivative instruments is tied to the performance of an underlying currency, security, index or other instrument. In addition to risks relating to their underlying instruments, the use of derivatives may include other, possibly greater, risks. Derivatives involve costs, may be volatile, and may involve a small initial investment relative to the risk assumed. Risks associated with the use of derivatives may include counterparty, leverage, correlation, liquidity, tax, market, interest rate and management risks. Derivatives may also be more difficult to purchase, sell or value than other investments. The Fund may lose more than the cash amount invested on investments in derivatives. Investors should bear in mind that, while the Fund intends to use derivative strategies, it is not obligated to actively engage in these transactions, generally or in any particular kind of derivative, if the investment manager elects not to do so due to availability, cost, market conditions or other factors.             Developing/Emerging Markets Securities Risk. Securities issued by foreign companies and governments located in developing/emerging countries may be affected more negatively by inflation, devaluation of their currencies, higher transaction costs, delays in settlement, adverse political developments, the introduction of capital controls, withholding taxes, nationalization of private assets, expropriation, social unrest, war or lack of timely information than those in developed countries.             Foreign Securities Risk. The Fund’s foreign investments may be affected by changes in a foreign country’s exchange rates, political and social instability, changes in economic or taxation policies, difficulties when enforcing obligations, decreased liquidity, and increased volatility. Foreign companies may be subject to less regulation resulting in less publicly available information about the companies.             Growth Investing Risk. Growth stocks tend to be more expensive relative to their earnings or assets compared with other types of stock. As a result they tend to be more sensitive to changes in their earnings and can be more volatile.             Management Risk. The investment techniques and risk analysis used by the Fund’s portfolio managers may not produce the desired results.             Market Risk. The prices of and the income generated by the Fund’s securities may decline in response to, among other things, investor sentiment, general economic and market conditions, regional or global instability, and currency and interest rate fluctuations.             Small- and Mid-Capitalization Risks. Stocks of small and mid-sized companies tend to be more vulnerable to adverse developments and may have little or no operating history or track record of success, and limited product lines, markets, management and financial resources. The securities of small and mid-sized companies may be more volatile due to less market interest and less publicly available information about the issuer. They also may be illiquid or restricted as to resale, or may trade less frequently and in smaller volumes, all of which may cause difficulty when establishing or closing a position at a desirable price.             Synthetic Securities Risk. Fluctuations in the values of synthetic securities may not correlate perfectly with the instruments they are designed to replicate. Synthetic securities may be subject to interest rate changes, market price fluctuations, counterparty risk and liquidity risk.
