PORTFOLIO TURNOVER

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 41.24%.

The example shows the operating expenses you would incur as a shareholder if you invested $10,000 in the Fund over the time periods shown and you redeem all your shares at the end of those periods. The example assumes that the average annual return was 5% and operating expenses remained the same.

Although your actual costs may be higher or lower, based on the above assumptions, your costs would be:

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund pursues its objective by investing primarily in a diversified portfolio of large-cap and mid-cap equity securities traded in U.S. markets and by writing call options on a substantial portion of the Fund’s long equity holdings (“Covered Call Options”). The subadviser focuses on companies with regular quarterly dividends and market capitalizations of $4 billion or more at the time of acquisition. The Fund places primary emphasis on the generation of income. Option premiums and dividend income are expected to constitute a significant portion of total return. Under normal circumstances, the Fund invests at least 80% of its assets in equity securities.

Equity Selection
The subadviser selects equity securities using a bottom-up investment approach focusing on the fundamentals of each company, emphasizing a company’s current dividend yield, free cash flow and stability. The Fund may invest in equity securities of foreign issuers that are traded in U.S. markets.

Covered Call Strategy
On an ongoing and consistent basis, the subadviser intends to write (sell) individual Covered Call Options as a means of enhancing return. Call options are contracts that give the purchaser of the option, in return for payment of a premium, the right, but not the obligation, to purchase from the writer of the option the security underlying the option at a specified exercise price prior to the expiration date. As the writer of a call option, the Fund receives the premium from the purchaser of the option and has the obligation, upon exercise of the option, to deliver the underlying security upon payment of the exercise price. If the option expires without being exercised, the Fund is not required to deliver the underlying security but retains the premium received.

The Fund generally writes Covered Call Options that are out-of-the money to generate premium income for the Fund. A call option is out-of-the money if the exercise price is above the current market price for the underlying security. The Fund will generally buy back call options that reach the exercise price, in lieu of allowing them to be exercised, and write a new option at a higher exercise price.

In addition to writing Covered Call Options, the Fund may also use certain derivatives transactions for hedging purposes or to seek total return. The subadviser currently intends to purchase put options on securities in the Fund’s portfolio and put options on securities indices.

The subadviser seeks to actively manage risk and adheres to a structured sell discipline.

Risk [Heading]

rr_RiskHeading

PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

You could lose money by investing in the Fund. There can be no assurance that the Fund’s investment objective will be achieved. The following is a summary of the principal risks of investing in the Fund.

Covered Call Strategy Risk. The Fund’s Covered Call Options strategy involves certain risks. These risks include:

• By selling Covered Call Options, the Fund limits its opportunity to profit from an increase in the price of the underlying stock above the exercise price, but continues to bear the risk of a decline in the value of the underlying stock. While the Fund receives a premium for writing the Covered Call Option, the price the Fund realizes from the sale of stock upon exercise of the option could be substantially below its current market price.
• A liquid market may not exist for the Covered Call Options written by the Fund. If the Fund is not able to close out a Covered Call Option transaction, the Fund will not be able to sell the underlying security until the option expires or is exercised.
• The Fund’s investment strategy may also result in a lack of liquidity of the purchase and sale of portfolio securities. Because the Fund generally will hold the stocks underlying the Covered Call Options, the Fund may be less likely to sell the stocks in its portfolio to take advantage of new investment opportunities.

If the Fund generates premiums from its writing Covered Call Options, these premiums typically will result in short-term capital gains for federal income tax purposes. Distributions of net short-term capital gain, are taxable to shareholders as ordinary income for federal income tax purposes. Transactions involving the disposition of the Fund’s underlying securities (whether pursuant to the exercise of a Covered Call Option or otherwise) will give rise to capital gains or losses. Because the Fund will have no control over the exercise of the Covered Call Option, it may be forced to realize capital gains or losses at inopportune times and it will not be able to control whether such gains or losses are short-term or long-term for federal income tax purposes. The Fund’s portfolio turnover rate does not take into account short-term capital gains generated from premiums on the sale of Covered Call Options. The Fund is not designed for investors seeking a tax-efficient investment.

Derivatives Risk. Risks associated with derivatives may include the risk that the derivative is imperfectly correlated with the security, index or currency to which it relates, the risk that derivatives may not have the intended effects and may result in losses or missed opportunities and the risk that the Fund will be unable to sell or otherwise close out the derivative. Derivative transactions could also expose the Fund to the effects of leverage, which could increase the Fund’s exposure to the market and magnify potential losses. There is no guarantee that derivatives, to the extent employed, will have the intended effect, and their use could cause lower returns or even losses to the Fund. The use of derivatives by the Fund to hedge risk may reduce the opportunity for gain by offsetting the positive effect of favorable price movements. The use of over-the-counter derivatives subjects the Fund to the risk that the counterparty to the derivative may be unwilling or unable to meet its obligations on the investment. The use of certain derivatives may expose the Fund to the underlying market or other reference asset in an amount exceeding the cash investment of the Fund.

Foreign Securities Risk. Investing in the securities of foreign issuers involves special risks and considerations in addition to those typically associated with investing in U.S. companies. These risks are heightened for issuers located in emerging markets. The securities of foreign companies may be less liquid and their prices may fluctuate more widely than those traded in U.S. markets. Foreign companies and markets may also have less governmental supervision. There may be difficulty in enforcing contractual obligations against, and little public information about, the companies. Trades typically take more time to settle and clear, and the costs of buying and selling foreign securities are generally higher than the costs associated with buying and selling securities traded in U.S. markets.

The values of the foreign securities held by the Fund may be affected by changes in currency exchange rates or control regulations. If a local currency gains against the U.S. dollar, the value of a holding denominated in that currency increases in U.S. dollar terms. If a local currency declines against the U.S. dollar, the value of the holding decreases in U.S. dollar terms. Changes in economic, tax or foreign investment policies, or other political, governmental or economic actions can adversely affect the value of the foreign securities held by the Fund. In foreign countries, accounting, auditing and financial reporting standards and other regulatory practices and requirements are generally different from those required for U.S. companies. Investments in securities of foreign issuers may also be subject to foreign withholding and other taxes.

Liquidity Risk. When there is no willing buyer and a security cannot be readily sold at the desired time or price, the Fund may need to accept a lower price or may not be able to sell the security at all. An inability to sell securities, at the Fund’s desired price or at all, can adversely affect the Fund’s value or prevent the Fund from being able to take advantage of other investment opportunities. Less liquid securities are more difficult to dispose of at their recorded values and are subject to wider bid-ask spreads and volatility.

Manager Risk. The performance of the Fund is dependent upon the investment adviser’s skill in selecting managers and the subadviser’s skill in making appropriate investments. As a result, the Fund may underperform its benchmark or its peers.

Market Risk. The Fund’s share price can move down in response to stock market conditions, changes in the economy or changes in a particular company’s stock price. An individual stock may decline in value even when the value of stocks in general is rising.

Mid-Cap Company Risk. Investments in mid-cap companies may entail greater risks than investments in larger, more established companies. Mid-cap companies generally have narrower product lines, limited financial resources and a limited trading market for their stocks compared with larger companies. As a result, their stock prices may experience greater volatility and may decline more than those of large-cap companies in market downturns.

The bar chart shows how the performance of the Class N shares of the Fund has varied from year to year over the periods shown. Class N shares and Class I shares are invested in the same portfolio of securities, so the annual returns would differ only to the extent that the classes have different expenses. The annual returns of the Class I shares would be higher than the returns of the Class N shares due to 12b-1 fees paid by Class N shares. This information may help illustrate the risks of investing in the Fund. The Fund makes updated performance information available on the Fund’s website, www.astonfunds.com, or by calling toll-free 800-992-8151.
