Strategic Alternatives Fund Investment Risks - Strategic Alternatives Fund
Dec. 31, 2025
Alternative Investments Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●Alternative Investments Risk: The Fund utilizes alternative investment strategies that are complex and may involve greater risk than traditional investments (i.e., stocks, bonds and cash). The performance of alternative investments is not expected to correlate closely with more traditional investments; however, it is possible that alternative investments will decline in value along with equity or fixed income markets, or both, or that they may not otherwise perform as expected. Alternative investments may have different characteristics and risks than do traditional investments; can be highly volatile; are often less liquid, particularly in periods of stress; are generally more complex and less transparent; and may have more complicated tax profiles than traditional investments. In addition, the performance of alternative investments may be more dependent on a Sub-Adviser's experience and skill than traditional investments. The use of alternative investments may not achieve the desired effect.
Below-Investment Grade Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●Below-Investment Grade Securities Risk: Below-investment grade securities (i.e., high yield securities or junk bonds, which are securities rated “Ba1” or lower by Moody's or the equivalent by S&P Global Ratings or Fitch or, if unrated, as determined by the Adviser or a Sub-Adviser to be of the same quality) involve greater risks of default, are more volatile than bonds rated investment grade and are inherently speculative. Issuers of these bonds may be more sensitive to economic downturns and may be unable to make timely interest or principal payments. The Fund’s value could be hurt by price declines due to actual or perceived changes in an issuer’s ability to make such payments. Bonds rated below-investment grade involve greater risks of default and are more volatile than bonds rated investment grade. Issuers of these bonds may be more sensitive to economic downturns and may be unable to make timely interest or principal payments. The Fund's value could be hurt by price declines due to actual or perceived changes in an issuer's ability to make such payments.
Cash Management Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●Cash Management Risk: Upon entering into certain derivatives contracts, such as futures contracts, and to maintain open positions in certain derivatives contracts, the Fund may be required to post collateral for the contract, the amount of which may vary. In addition, the Fund may maintain cash and cash equivalent positions to manage the Fund’s market exposure and for other portfolio management purposes. As such, the Fund may maintain cash balances, including foreign currency balances, which may be significant, with counterparties. The Fund is thus subject to counterparty risk and credit risk with respect to these arrangements.
Contingent Convertible Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●Contingent Convertible Securities Risk: Contingent convertible securities are a form of hybrid security that are intended to either convert into equity or have their principal written down upon the occurrence of certain triggers. The triggers are generally linked to regulatory capital thresholds or regulatory actions calling into question the issuer’s continued viability as a going concern. Investment in this particular type of bond may result in material losses to the Fund based on certain trigger events. The existence of these trigger events creates a different type of risk from traditional bonds and may more likely result in a partial or total loss of value or alternatively they may be converted into shares of the issuing company which may also have suffered a loss in value.
Controlling Voting Interest Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●Controlling Voting Interest Risk: In accordance with the GuideStone Funds Trust Instrument, GuideStone will, at all times, directly or indirectly own, control or hold with power to vote at least 60% of the outstanding shares of GuideStone Funds. This means that GuideStone will control the vote on any matter that requires the approval of a majority of the outstanding shares of GuideStone Funds.
Credit Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●Credit Risk: There is a risk that the issuer of a fixed income investment owned by the Fund, or the counterparty to a derivatives contract, repurchase agreement, loan of portfolio securities or other transaction to which the Fund is party, may fail to pay interest or even principal due in a timely manner or at all.
Currency Strategy Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●Currency Strategy Risk: There is no guarantee that the Fund’s currency investment strategy will be successful. Currency rates may fluctuate significantly over short or extended periods of time (i.e., may be extremely volatile), which could result in losses to the Fund if currencies do not perform as a Sub-Adviser expects. Changes in foreign currency exchange rates could adversely impact investment gains or add to investment losses. Generally, when the U.S. dollar rises in value against a foreign currency, an investment denominated in that country’s currency loses value because that currency is worth fewer U.S. dollars. Conversely, when the U.S. dollar decreases in value against a particular foreign currency, investments denominated in that currency increase in value. In general, currency exchange rates can be unpredictably affected by various factors, including political developments and governmental, supranational entity or central bank action or inaction. The Fund may also be positively or negatively affected by governmental strategies intended to make the currencies in which the Fund invests stronger or weaker. In addition, currency markets generally are not as regulated as securities markets, which could expose the Fund to additional risks. Some currency transactions may involve a higher level of risk than other investments relative to the amount invested and the impact of any gain or loss may be magnified. The risks of currency transactions also may be heightened in developing or emerging market countries.
Depositary Receipts Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●Depositary Receipts Risk: Investments in depositary receipts (i.e., American Depositary Receipts) are generally subject to the same risks of investing directly in the foreign securities that they evidence or into which they may be converted, including, but not limited to, currency fluctuations and political and financial instability in the home country of a particular depositary receipt or foreign stock. In addition, securities of foreign issuers may be negatively affected by political events, economic conditions or inefficient, illiquid or unregulated markets in foreign countries. Foreign issuers may be subject to inadequate regulatory or accounting standards, which may increase investment risk as there may be an imperfect correlation between the market value of depositary receipts and the underlying foreign securities. In addition, issuers underlying unsponsored depositary receipts may not provide as much information as U.S. issuers and issuers underlying sponsored depositary receipts. Unsponsored depositary receipts also may not carry the same voting privileges as sponsored depositary receipts.
Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●Derivatives Risk: Derivatives involve risks different from, and in some respects greater than, those associated with investing directly in securities, currencies or other instruments. Derivatives may be illiquid or less liquid, volatile, difficult to price and leveraged so that small changes in the value of the underlying instruments may produce disproportionate losses to the Fund. There may be imperfect correlation between a derivative and the reference instrument underlying the derivative. Derivatives involve counterparty risk, which is the risk that the other party to the derivative will fail to make required payments or otherwise comply with the terms of the derivative. That risk is generally thought to be greater with over-the-counter (OTC) derivatives than with derivatives that are centrally cleared. However, derivatives traded on organized exchanges and/or through clearing organizations involve the possibility that the futures commission merchant or clearing organization will default in the performance of its 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.
Emerging Markets Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●Emerging Markets Risk: When investing in emerging markets, the risks of investing in foreign securities is heightened. Emerging markets are generally smaller, less developed, less liquid and more volatile than the securities markets of the U.S. and other developed markets. There are also risks of: greater political or economic uncertainties; an economy’s dependence on revenues from particular commodities or on international aid or development assistance; currency transfer restrictions; a limited number of potential buyers for such securities resulting in increased volatility and limited liquidity for emerging market securities; trading suspensions; and delays and disruptions in securities settlement procedures. The governments of emerging market countries may also be more unstable and more likely to impose capital controls, nationalize a company or industry, place restrictions on foreign ownership and on withdrawing sale proceeds of securities from the country, intervene in the financial markets and/or impose burdensome taxes that could adversely affect security prices. In addition, there may be less publicly available information about issuers in emerging markets than would be available about issuers in more developed capital markets, and such issuers may not be subject to accounting, auditing and financial reporting standards and requirements comparable to those to which U.S. companies are subject. Emerging markets are financial markets in countries with developing economies, where industrialization has commenced and the economy has linkages with the global economy. Generally, emerging markets are located in Latin America, Eastern Europe, and Asia (excluding Japan).
Equity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●Equity Risk: Stocks and other equity securities generally fluctuate in value more than fixed income securities and may decline significantly over short time periods. There is a chance that stock prices overall will decline because stock markets tend to move in cycles with periods of rising and falling prices. The market value of a stock may fall due to changes in a company’s financial condition as well as general market, economic and political conditions and other factors.
Faith-Based Investing Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●Faith-Based Investing Risk: The Fund invests in accordance with the faith-based investment restrictions of GuideStone. The Fund may not be able to take advantage of certain investment opportunities due to these restrictions, which may adversely affect investment performance. In evaluating an investment, the Adviser or Sub-Adviser is dependent upon information and data that may be incomplete, inaccurate or unavailable, which could adversely affect the analysis of the factors relevant to a particular investment.
Fixed Income Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●Fixed Income Securities Risk: The value of fixed income securities held by the Fund will fluctuate in response to changes in interest rates and other economic factors. When interest rates rise, the prices of fixed income securities fall and vice versa. Typically, the longer the maturity or duration of a debt security, the greater the effect a change in interest rates could have on the security's price. Thus, the sensitivity of the Fund's debt securities to interest rates will increase with any increase in the duration of those securities. Recent events in the fixed income market may expose the Fund to heightened interest rate risk and volatility. The Board of Governors of the Federal Reserve System continued to lower interest rates following a period of consistent rate increases, though it is unclear if such lowering will continue. Very low or negative interest rates may impact the yield of the Fund’s investments in fixed income securities and may increase the risk that, if followed by rising interest rates, the Fund’s performance will be negatively impacted. Recent and potential future changes in government policy may affect interest rates. Changing interest rates, including rates that fall below zero, can be sudden and unpredictable and may have unpredictable effects on markets, may result in heightened market volatility and may detract from Fund performance to the extent the Fund is exposed to such interest rates and/or volatility. The Fund is also subject to the risk that the income generated by its investments in fixed income securities may not keep pace with inflation. Other factors may affect fixed income securities, such as financial conditions of a particular issuer, including its credit standing, and general economic conditions. The yield earned by the Fund will also vary with changes in interest rates and other economic factors.
Floating Rate Loan Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●Floating Rate Loan Risk: Senior secured and unsecured floating rate loans are generally acquired as a participation interest in, or assignment of, loans originated by U.S. banks and other financial institutions (Senior Loans) and are subject to the risk that a court could subordinate a Senior Loan, which typically holds the most senior position in the issuer’s capital structure, to presently existing or future indebtedness or take other action detrimental to the holders of Senior Loans. Senior Loans are often below-investment grade and are considered to be inherently speculative. If the Fund acquires a participation interest in a Senior Loan, the Fund may not be able to control the exercise of any remedies that the lender would have under the loan and likely would not have any rights against the borrower directly. Senior Loans made to finance highly leveraged corporate acquisitions may be especially vulnerable to adverse changes in economic or market conditions. To the extent that the Fund invests in loan participations and assignments, it is subject to the risk that the financial institution acting as agent for all interests in a loan might fail financially. It is also possible that the Fund could be held liable, or may be called upon to fulfill other obligations as a co-lender. To the extent a Senior Loan is secured by collateral, it is subject to the risk that the value of the collateral will decline and be insufficient to cover the amount of the loan. Senior Loans are also subject to liquidity risks because they may not have an active trading market, may have less publicly available information about them and may be subject to restrictions on transfer, which may result in the Fund being unable to sell the Senior Loans at a favorable price. Loan interests may be difficult to value and may have extended trade settlement periods that may be greater than seven days. Accordingly, the proceeds from the sale of a loan may not be available to make additional investments or to meet redemption obligations until potentially a substantial period after the sale of the loan. The extended trade settlement periods could force the Fund to liquidate other securities to meet redemptions and may present a risk that the Fund may incur losses in order to timely honor redemptions. Senior loans may not be considered “securities,” and therefore, purchasers may not be entitled to rely on the antifraud protections of the federal securities laws.
Foreign Currency Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●Foreign Currency Tax Risk: If the U.S. Treasury were to exercise its authority to issue regulations that exclude from the definition of “qualifying income” foreign currency gains not directly related to a Fund’s business of investing in securities, the Fund may be unable to qualify as a regulated investment company for one or more years. In this event, the Board of Directors of GuideStone Funds may authorize a significant change in investment strategy or other action.
Foreign Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●Foreign Securities Risk: Obligations or securities of foreign issuers may be negatively affected by political events, economic conditions or inefficient, illiquid or unregulated markets in foreign countries. Foreign issuers may be subject to inadequate regulatory or accounting standards, which may increase investment risk. Security values also may be negatively affected by changes in the exchange rates between the U.S. dollar and foreign currencies. It may take more time to clear and settle trades involving foreign securities. In addition, securities issued by U.S. entities with substantial foreign operations or holdings can involve risks relating to conditions in foreign countries.
Forward Currency Contract Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●Forward Currency Contract Risk: A forward foreign currency exchange contract is an agreement to buy or sell a specific currency at a future date and at a price set at the time of the contract. Foreign forward currency exchange contracts involve a risk of loss if currency exchange rates move against the Fund and are subject to counterparty risk.
Futures and Options on Futures Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●Futures and Options on Futures Risk: There is a risk that the prices of futures and options on futures contracts will diverge from the prices of their underlying instruments. Futures and options prices are affected by such factors as current and anticipated short-term interest rates, changes in volatility of the underlying instrument and the time remaining until expiration of the contract, which may not affect security prices the same way. Imperfect or no correlation also may result from differing levels of demand in the options and futures markets and the securities markets, from structural differences in how options and futures and securities are traded and from imposition of daily price fluctuation limits or trading halts. There can be no assurance that, at all times, a liquid market will exist for offsetting a futures or options contract that the Fund has previously bought or sold and this may result in the inability to close a contract when desired.
High Portfolio Turnover Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●High Portfolio Turnover Risk: The Fund may engage in active and frequent trading and expects to have a high portfolio turnover rate. High turnover could produce higher transaction costs and taxable distributions and lower the Fund’s after-tax performance.
Large Shareholder Transactions Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●Large Shareholder Transactions Risk: The Fund may experience adverse effects when certain large shareholders, including institutional accounts managed by the Adviser’s affiliates, as well as other series of GuideStone Funds (i.e., funds) that invest in the Fund, purchase or redeem large amounts of Fund shares. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund’s net asset value and liquidity. Similarly, large Fund share purchases may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions also will increase the distribution of taxable income to shareholders if sales of portfolio investments result in gains, and may also increase transaction costs. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s expense ratio.
Leverage Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●Leverage Risk: The Fund is subject to leverage risk. Leveraging occurs when the Fund increases its assets available for investment using borrowings or similar transactions. Due to the fact that short sales involve borrowing securities and selling them, the Fund’s short sales effectively leverage the Fund’s assets. The use of leverage, including short sales and other forms of leveraging such as lending portfolio securities, entering into futures contracts and engaging in forward commitment transactions, may magnify the Fund’s gains or losses. Leverage also creates interest expense that may lower the Fund’s overall returns.
Liquidity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●Liquidity Risk: Certain investments may be difficult or impossible for the Fund to purchase or sell at an advantageous time or price or in sufficient amounts to achieve the desired level of exposure, particularly in times of market turmoil or adverse investor perceptions. The Fund may be required to dispose of investments at unfavorable times or prices in order to satisfy redemptions, which may result in a loss or may be costly to the Fund. Illiquid investments may be more difficult to value. Judgment plays a greater role in valuing illiquid investments than investments with more active markets. Certain securities that were liquid when purchased may later become illiquid, particularly in times of overall economic distress.
Market Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●Market Risk: The Fund’s value will go up and down in response to changes in the market value of its investments, sometimes rapidly and unpredictably. Market value will change due to business developments concerning a particular issuer or industry, as well as general market and economic conditions. Changes in the financial condition of a single issuer can impact the market as a whole. Geopolitical risks, including terrorism, tensions, trade disputes or open conflict between nations, or political or economic dysfunction within some nations that are major players on the world stage or major producers of oil, may lead to instability in world economies and markets, may lead to increased market volatility and may have adverse long-term effects. Additionally, the imposition of tariffs or trade restrictions can disrupt global supply chains, increase costs for certain industries, and contribute to heightened market volatility, which may adversely affect the Fund's investments. Local, regional or global events such as the spread of infectious illnesses or other public health issues, recessions, natural disasters or other events could have a significant impact on the Fund and its investments. In addition, markets and market participants are increasingly reliant upon information data systems. Data imprecision, software or other technology malfunctions, programming inaccuracies, unauthorized use or access and similar circumstances may have an adverse impact upon a single issuer, a group of issuers or the market at-large. Additionally, legislative, regulatory, or tax developments may affect the investments or investment strategies available to the Adviser in connection with managing the Fund, which may also adversely affect the ability of the Fund to achieve its investment objective.
Mid-Capitalization Companies Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●Mid-Capitalization Companies Risk: Medium-sized company (i.e., mid-cap) stocks have historically been subject to greater investment risk than large company stocks. They generally are more vulnerable than larger companies to adverse business or economic developments. The risks generally associated with these companies include more limited product lines, markets and financial resources, lack of management depth or experience, dependency on key personnel and vulnerability to adverse market and economic developments. Accordingly, the prices of medium-sized company stocks tend to be more volatile than prices of large company stocks.
Mortgage- and Asset-Backed Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●Mortgage- and Asset-Backed Securities Risk: The Fund is subject to the risk that the principal on mortgage- and asset-backed securities held by the Fund will be prepaid, which generally will reduce the yield and market value of these securities. If interest rates fall, the rate of prepayments tends to increase as borrowers are motivated to pay off debt and refinance at new lower rates. Rising interest rates may increase the risk of default by borrowers and tend to extend the duration of these securities, making them more sensitive to changes in interest rates. As a result, in a period of rising interest rates, to the extent the Fund holds these types of securities, it may experience additional volatility and losses. This is known as extension risk. Moreover, declines in the credit quality of the issuers of mortgage- and asset-backed securities or instability in the markets for such securities may affect the value and liquidity of such securities, which could result in losses to the Fund. In addition, certain mortgage- and asset-backed securities may include securities backed by pools of loans made to “subprime” borrowers or borrowers with blemished credit histories; the risk of defaults is generally higher in the case of mortgage pools that include such subprime mortgages.
Multiple Sub-Adviser Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●Multiple Sub-Adviser Risk: Fund performance is dependent upon the success of the Adviser and the Sub-Advisers in implementing the Fund’s investment strategies in pursuit of the Fund’s investment objective. To a significant extent, the Fund’s performance will depend on the success of the Adviser’s methodology in allocating the Fund’s assets to Sub-Advisers and its selection and oversight of the Sub-Advisers. The Sub-Advisers’ investment styles may not work together as planned, which could adversely affect the performance of the Fund. In addition, because each Sub-Adviser makes its trading decisions independently, it is possible that the Sub-Advisers may purchase or sell the same security at the same time without aggregating their transactions or hold long and short positions in the same security at the same time. This may cause unnecessary brokerage and other expenses. A Sub-Adviser’s strategy may be out of favor at any time.
Options Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●Options Risk: The use of options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying reference asset. By writing put options, the Fund takes on the risk of declines in the value of the underlying instrument, including the possibility of a loss up to the entire strike price of each option it sells but without the corresponding opportunity to benefit from potential increases in the value of the underlying instrument. When the Fund writes a put option, it assumes the risk that it must purchase the underlying instrument at an exercise price that may be higher than the market price of the instrument. If there is a broad market decline and the Fund is not able to close out its written put options, it may result in substantial losses to the Fund. The Fund will receive a premium from writing options, but the premium received may not be sufficient to offset any losses sustained from exercised put options.
Short Sale and Short Position Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●Short Sales and Short Position Risk: Short sales involve selling a security the Fund does not own in anticipation that the security will decline in price. The Fund will suffer a loss if it sells a security short and the value of the security rises rather than falls. Short sales expose the Fund to the risk that it will be required to buy the security sold short (also known as “covering” the short position) at a time when the security has appreciated in value, thus resulting in a loss to the Fund. The Fund’s potential loss on a short position is limited only by the maximum attainable price of the security less the price at which the security was sold by the Fund. Therefore, in theory, stocks sold short have unlimited risk. The Fund’s use of short sales in effect “leverages” the Fund. The Fund’s short strategy depends on counterparties from which the Fund borrows securities. The Fund must post collateral when borrowing securities and the Fund is subject to the risk of default by a counterparty, which could result in a loss of collateral and money owed to the Fund.
Sovereign Debt Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●Sovereign Debt Risk: Sovereign debt securities are subject to the risk that a governmental entity may delay or refuse to pay interest or principal on its sovereign debt, due, for example, to cash flow problems, insufficient foreign currency reserves, political considerations, the size of the governmental entity’s debt position in relation to the economy, its policy toward international lenders or the failure to put in place economic reforms required by multilateral agencies. If a governmental entity defaults, it may ask for more time in which to pay or for further loans. There may be no legal process for collecting sovereign debt that a government does not pay nor are there bankruptcy proceedings through which all or part of the sovereign debt that a governmental entity has not repaid may be collected. Sovereign debt risk is increased for emerging market issuers.
Special Situations Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●Special Situations Risk: In general, securities of companies which are the subject of a tender or exchange offer or a merger, consolidation, bankruptcy, liquidation, reorganizations or restructuring proposal sell at a premium to their historic market price immediately prior to the announcement of the transaction. However, it is possible that the value of securities of a company involved in such a transaction will not rise and in fact may fall, in which case the Fund would lose money. It is also possible that the transaction may not be completed as anticipated or may take an excessive amount of time to be completed, in which case the Fund may not realize any premium on its investment and could lose money if the value of the securities declines during the Fund’s holding period. In some circumstances, the securities purchased may be illiquid making it difficult for the Fund to dispose of them at an advantageous price.
Swaps Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●Swaps Risk: Swaps can involve greater risks than direct investments in securities, because swaps may be leveraged and subject to counterparty credit risk. If the counterparty fails to meet its obligations, the Fund may lose money. Swaps are also subject to valuation risk and may in some cases be illiquid.
U.S. Government Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●U.S. Government Securities Risk: Not all obligations of U.S. government agencies and instrumentalities are backed by the full faith and credit of the U.S. Treasury. Some are backed by a right to borrow from the U.S. Treasury, while others are backed only by the credit of the issuing agency or instrumentality. Accordingly, these securities carry at least some risk of non-payment. It is possible that issuers of U.S. government securities will not have the funds to meet their payment obligations in the future.
Volatility Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●Volatility Risk: The Fund may be unsuccessful in maintaining a portfolio of investments that minimize volatility, and there is a risk that the Fund may experience more than minimal volatility. Securities held by the Fund are subject to price volatility and the prices may not be any less, and may be more, volatile than the market as a whole. In addition, the use of volatility management techniques may limit the Fund’s participation in market gains, particularly during periods when market values are increasing, but market volatility is high.
Risk Lose Money [Member]

Risk [Text Block] It is possible to lose money by investing in the Fund.
Risk Not Insured Depository Institution [Member]  
Prospectus [Line Items]  
Risk [Text Block] An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
