Aug. 31, 2024
Risk Lose Money [Member]  
Prospectus [Line Items]  
Risk [Text Block] You may lose money by investing in the fund.
Risk Not Insured [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.
Asset allocation risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Asset allocation risk: The risk that the fund may allocate assets to an asset category that underperforms other asset categories.
Equity risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Equity risk: Stocks and other equity securities, and securities convertible into stocks, generally fluctuate in value more than bonds. Preferred stocks in which the fund may invest are also sensitive to interest rate changes. The rights of preferred stocks on the distribution of a company's assets in the event of a liquidation are generally subordinate to the rights associated with a company's debt securities. The fund could lose all of its investment in a company's stock.
Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Interest rate risk: An increase in prevailing interest rates typically causes the value of fixed income securities to fall. Changes in interest rates will likely affect the value of longer-duration fixed income securities more than shorter-duration securities and higher quality securities more than lower quality securities. When interest rates are falling, some fixed income securities provide that the issuer may repay them earlier than the maturity date, and if this occurs the fund may have to reinvest these repayments at lower interest rates. The fund may face a heightened level of interest rate risk due to certain changes in general economic conditions, inflation and monetary policy, such as certain types of interest rate changes by the Federal Reserve.
Credit Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Credit risk: The risk that the fund could lose money if the issuer or guarantor of a fixed income security, or the counterparty to or guarantor of a derivative contract or transaction, is unable or unwilling to meet its financial obligations. This risk is likely greater for lower quality investments than for investments that are higher quality.
High yield securities ("junk bonds") risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] High yield securities ("junk bonds") risk: Lower-rated securities (the issuers of which are typically in poorer financial health) are subject to higher risks than investment grade securities. For example, lower-rated securities may be (1) subject to a greater risk of loss of principal and non-payment of interest (including default by the issuer); (2) subject to greater price volatility; and (3) less liquid than investment grade securities. The prices of such securities may be more vulnerable to bad economic news, or even the expectation of bad news, than higher rated fixed income securities.
US government securities risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] US government securities risk: There are different types of US government securities with different levels of credit risk, including the risk of default, depending on the nature of the particular government support for that security. For example, a US government-sponsored entity, such as Federal National Mortgage Association ("Fannie Mae") or Federal Home Loan Mortgage Corporation ("Freddie Mac"), although chartered or sponsored by an Act of Congress, may issue securities that are neither insured nor guaranteed by the US Treasury and are therefore riskier than those that are. Securities issued or guaranteed by the US Treasury are backed by the full faith and credit of the United States, but are guaranteed only as to the timely payment of interest and principal when held to maturity, and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the timely payment of interest or principal, which could result in losses to the fund (e.g., Congressional debt ceiling impasses).
Limited capitalization risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Limited capitalization risk: The risk that securities of smaller capitalization companies tend to be more volatile and less liquid than securities of larger capitalization companies. This can have a disproportionate effect on the market price of smaller capitalization companies and affect the fund's ability to purchase or sell these securities. In general, smaller capitalization companies are more vulnerable than larger companies to adverse business or economic developments and they may have more limited resources.
Market risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Market risk: The risk that the market value of the fund's investments may fluctuate, sometimes rapidly or unpredictably, as the stock and bond markets fluctuate. Market risk may affect a single issuer, industry, or sector of the economy, or it may affect the market as a whole. Moreover, changing market, economic, political and social conditions in one country or geographic region could adversely impact market, economic, political and social conditions in other countries or regions.
Derivatives risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Derivatives risk: The value of derivatives—so called because their value derives from the value of an underlying asset, reference rate or index—may rise or fall more rapidly than other investments. It is possible for the fund to lose more than the amount it invested in the derivative. When using derivatives for hedging purposes, the fund's overall returns may be reduced if the hedged investment experiences a favorable price movement. In addition, if the fund has insufficient cash to meet daily variation margin or payment requirements, it may have to sell securities from its portfolio at a time when it may be disadvantageous to do so. The risks of investing in derivative instruments also include market, leverage, operational, legal, and management risks. Derivatives relating to fixed income markets are especially susceptible to interest rate risk and credit risk. In addition, many types of swaps and other derivatives may be subject to liquidity risk, counterparty risk, credit risk and mispricing or valuation complexity. Derivatives also involve the risk that changes in the value of a derivative may not correlate as anticipated with the underlying asset, rate, index or overall securities markets, thereby reducing their effectiveness. These derivatives risks are different from, and may be greater than, the risks associated with investing directly in securities and other instruments. Regulation relating to a mutual fund's use of derivatives and related instruments, including Rule 18f-4 under the Investment Company Act of 1940, as amended, could potentially limit or impact the fund's ability to invest in derivatives, limit the fund's ability to employ certain strategies that use derivatives and/or adversely affect the value of derivatives and the fund's performance.
Valuation risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Valuation risk: During periods of reduced market liquidity or in the absence of readily available market quotations for investments, the ability of the fund to value the fund's investments becomes more difficult and the judgment of the fund's investment advisor may play a greater role in the valuation of the investments due to reduced availability of reliable objective pricing data.
Prepayment Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Prepayment risk: The fund's mortgage- and asset-backed securities, as applicable, may be prepaid more rapidly than expected, especially when interest rates are falling, and the fund may have to reinvest those prepayments at lower interest rates. When interest rates are rising, slower prepayments may extend the duration of the securities and may reduce their value.
Risk associated with value investing [Member]  
Prospectus [Line Items]  
Risk [Text Block] Risk associated with value investing: Securities selection based on value orientation involves certain risks. Because the prices of value-oriented stocks tend to correlate more closely with economic cycles than growth-oriented stocks, value-oriented stocks generally may be more sensitive to changing economic conditions, such as changes in interest rates, corporate earnings and industrial production.
Management risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Management risk: The risk that the investment strategies, techniques and risk analyses employed by UBS AM may not produce the desired results.
Investment company risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Investment company risk: Investments in open- or closed-end investment companies, including ETFs, involve certain risks. The shares of other investment companies are subject to management fees and other expenses of those companies, and the purchase of shares of some investment companies requires the payment of sales loads and (in the case of closed-end investment companies) sometimes substantial premiums above the value of such companies' portfolio securities.
Portfolio turnover risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Portfolio turnover risk: The fund may engage in frequent trading from time to time, which can result in high portfolio turnover. A high portfolio turnover rate involves greater expenses to the fund, including transaction costs, and is likely to generate more taxable short-term gains for shareholders, which may have an adverse impact on performance.
IPOs risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] IPOs risk: The purchase of shares issued in IPOs may expose the fund to the risks associated with issuers that have no operating history as public companies, as well as to the risks associated with the sectors of the market in which the issuer operates. The market for IPO shares may be volatile, and share prices of newly-public companies may fluctuate significantly over a short period of time.
Investing in ETFs risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Investing in ETFs risk: The fund's investment in ETFs may subject the fund to additional risks than if the fund would have invested directly in the ETF's underlying securities. These risks include the possibility that an ETF may experience a lack of liquidity that can result in greater volatility than its underlying securities; an ETF may trade at a premium or discount to its net asset value; an ETF may not replicate exactly the performance of the benchmark index it seeks to track; trading an ETF's shares may be halted if the listing exchange's officials deem such action appropriate; and a passively managed ETF would not necessarily sell a security because the issuer of the security was in financial trouble unless the security is removed from the index that the ETF seeks to track. In addition, investing in an ETF may also be more costly than if the fund had owned the underlying securities directly. The fund, and indirectly, shareholders of the fund, bear a proportionate share of the ETF's expenses, which include management and advisory fees and other expenses. In addition, the fund will pay brokerage commissions in connection with the purchase and sale of shares of the ETF.
