The Materials Select Sector SPDR Premium Income Fund Investment Risks - The Materials Select Sector SPDR Premium Income Fund	Aug. 01, 2025
Prospectus [Line Items]
Risk [Text Block]	Tax Risk: The Fund's covered call strategy may be subject to U.S. federal income tax rules that could adversely affect the amount, character and timing of the Fund's gains and losses, and of distributions to Fund shareholders. The Fund's covered call strategy could result in the Fund recognizing significant amounts of short-term capital gain, which is taxable as ordinary income when distributed to shareholders. The Fund's covered call strategy may result in the Fund's investments being subject to the U.S. federal income tax rules applicable to “straddles.” If positions held by the Fund are treated as “straddles” for tax purposes, or the Fund's risk of loss with respect to a position is otherwise diminished as set forth in applicable regulations, dividends on stocks that are part of such positions may not be eligible to be treated as qualified dividend income for non-corporate shareholders or for the dividends received deduction for corporate shareholders. Under the straddle rules, if applicable: (1) any loss realized on disposition of one position of a straddle may not be recognized to the extent that the Fund has unrealized gains with respect to the other position in the straddle; (2) the Fund's holding period in straddle positions may be suspended while the straddle exists, which could result in a gain being treated as short-term capital gain rather than long-term capital gain; (3) the losses recognized with respect to certain positions that are part of a “mixed straddle” may be treated as 60% long-term and 40% short-term capital loss; (4) losses recognized with respect to certain straddle positions that would otherwise be short-term capital losses may be treated as long-term capital losses; and (5) the deduction of interest and carrying charges attributable to certain straddle positions may be deferred.
Market Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Market Risk: The Fund's investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities markets. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, inflation, changes in the actual or perceived creditworthiness of issuers, and general market liquidity. The Fund is subject to the risk that geopolitical events will disrupt securities markets and adversely affect global economies and markets. Local, regional or global events such as war, military conflicts, acts of terrorism, trade policy changes or disputes, the threat or actual imposition of tariffs, natural disasters, the spread of infectious illness or other public health issues, or other events could have a significant impact on the Fund and its investments.
Equity Investing Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Equity Investing Risk: The market prices of equity securities owned by the Fund may go up or down, sometimes rapidly or unpredictably. The value of a security may decline for a number of reasons that may directly relate to the issuer and also may decline due to general industry or market conditions that are not specifically related to a particular company. In addition, equity markets tend to move in cycles, which may cause stock prices to fall over short or extended periods of time.
Materials Sector Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Materials Sector Risk: The Fund's assets will be concentrated in the materials sector, which means the Fund will be more affected by the performance of the materials sector than a fund that is more diversified. Many materials companies are significantly affected by the level and volatility of commodity prices, exchange rates, import controls, worldwide competition, environmental policies and consumer demand. At times, worldwide production of industrial materials has exceeded demand as a result of over-building or economic downturns, leading to poor investment returns or losses. Other risks may include liabilities for environmental damage and general civil liabilities, depletion of resources, and mandated expenditures for safety and pollution control. The materials sector may also be affected by economic cycles, technical progress, labor relations, and government regulations.
Call Writing Strategy Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Call Writing Options Strategy Risk: The Fund's use of call options involves speculation and can lead to losses because of adverse movements in the price or value of the underlying stock, index, or other asset, which may be magnified by certain features of the options. The Fund's successful use of call options depends on the ability of the Adviser to forecast market movements correctly. For example, if the Fund were to write (sell) a call option on an index or security based on the Adviser's expectation that the price of an index or security would fall, but the price were to rise instead, the Fund could be required to sell the underlying asset upon exercise at a price below the current market price. When selling a call option, the Fund will receive a premium; however, this premium may not be enough to offset a loss incurred by the Fund if the price of the underlying asset is above the strike price by an amount equal to or greater than the premium. The value of an option may be adversely affected if the market for the option becomes less liquid or smaller, and will be affected by changes in the value or yield of the option's underlying asset, an increase in interest rates, a change in the actual or perceived volatility of the stock market or the underlying asset and the remaining time to expiration. Additionally, the value of an option does not increase or decrease at the same rate as the underlying asset(s). In addition, if the price of the underlying asset of an option is above the strike price of a written call, the value of the option, and consequently of the Fund, may decline significantly more than if the Fund invested directly in the underlying asset instead of using options. The Fund could experience a loss if its options do not perform as anticipated, or are not correlated with the performance of their underlying asset or if the Fund is unable to purchase or liquidate a position because of an illiquid secondary market. As an option on an underlying asset held by the Fund nears expiration, they are generally closed out and replaced by another option with a later expiration (commonly referred to as “rolling the option”). There is no assurance that the Fund will be able to roll the option or effect a different closing transaction at any particular time or at an acceptable price. The sale of call options by the Fund may create investment leverage. Frequent selling of call options may result in higher Fund expenses and may result in increased distributions to investors, including potentially increased distributions that are taxable to individuals as ordinary income.
FLEX Options [Member]
Prospectus [Line Items]
Risk [Text Block]	FLEX Options: The Fund may utilize FLEX Options guaranteed for settlement by the Options Clearing Corporation (“OCC”). Although unlikely, it is possible the OCC is unable to meet its settlement obligations, which could result in substantial loss for the Fund. FLEX Options may be less liquid than more traditional exchange-traded option contracts. Upon expiration, the FLEX Options held by the Fund will be exercisable at the strike price. Prior to the expiration date, the value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. The value of the FLEX Options prior to the expiration date may vary due to factors other than the value of underlying asset, such as interest rate changes, changing supply and demand, decreased liquidity of the FLEX Options, a change in the actual and perceived volatility of the stock market and underlying asset, and the remaining time to expiration.
Exchange Traded Funds Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Exchange-Traded Funds Risk: The Fund is subject to substantially the same risks as those associated with the direct ownership of the securities represented by an underlying ETF in which it invests. In addition, the shares of an underlying ETF may trade at a premium or discount to their intrinsic value (i.e., the market value may differ from the net asset value (“NAV”) of an ETF's shares) for a number of reasons. For example, supply and demand for shares of an underlying ETF or market disruptions may cause the market price of the underlying ETF to deviate from the value of the underlying ETF's investments, which may be exacerbated in less liquid markets.
Affiliated ETF Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Affiliated ETF Risk: The Fund invests in an affiliated underlying ETF and, as a result, the Fund's investment performance and risks are directly related to the investment performance and risks of the affiliated ETF. In addition, the Adviser may have an incentive to take into account the effect on an affiliated ETF in which the Fund may invest in determining whether, and under what circumstances, to purchase or sell shares in that affiliated ETF. Although the Adviser takes steps to address the conflicts of interest, it is possible that the conflicts could impact the Fund.
Fluctuation of Net Asset Value Share Premiums and Discounts Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Fluctuation of Net Asset Value, Share Premiums and Discounts Risk: As with all exchange-traded funds, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund's daily NAV per share and there may be times when the market price of the shares is more than the NAV per share (premium) or less than the NAV per share (discount). This risk is heightened in times of market volatility or periods of steep market declines.
Futures Contract Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Futures Contract Risk: A futures contract is a standardized agreement that calls for the purchase or sale of a specific asset at a specific price at a specific future time, or cash settlement of the terms of the contract. Transactions in futures contracts can create investment leverage and may have significant volatility. It is possible that a futures contract transaction will result in a much greater loss than the principal amount invested, and the Fund may not be able to close out the futures contract at a favorable time or price. There is no assurance that a liquid secondary market on an exchange will exist for any particular futures contract. In the event no such market exists, it might not be possible to effect closing transactions, and the Fund will be unable to terminate its exposure to the futures contract. There is also a risk of imperfect correlation between movements in the prices of the futures contract and movements in the price of the underlying assets. The counterparty to a futures contract may be unable or unwilling to make timely settlement payments, return the Fund's margin, or otherwise honor its obligations.
Large Capitalization Securities Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Large-Capitalization Securities Risk: Returns on investments in securities of large companies could trail the returns on investments in securities of smaller and mid-sized companies. Larger companies may be unable to respond as quickly as smaller and mid-sized companies to competitive challenges or to changes in business, product, financial, or market conditions. Larger companies may not be able to maintain growth at the high rates that may be achieved by well-managed smaller and mid-sized companies.
Management Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Management Risk: The Fund is actively managed. The Adviser's judgments about the attractiveness, relative value, or potential appreciation of a particular sector, security, commodity or investment strategy may prove to be incorrect, and may cause the Fund to incur losses. There can be no assurance that the Adviser's investment techniques and decisions will produce the desired results.
New Fund Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	New Fund Risk: The Fund is new and there is no assurance that the Fund will grow quickly. When the Fund's size is small, the Fund may experience low trading volume, which could lead to wider bid/ask spreads. In addition, the Fund may face the risk of being delisted if the Fund does not meet certain conditions of the listing exchange. Any resulting liquidation of the Fund could cause elevated transaction costs for the Fund and negative tax consequences for its shareholders.
Risk Lose Money [Member]
Prospectus [Line Items]
Risk [Text Block]	As with all investments, there are certain risks of investing in the Fund. The Fund's exposure to risks discussed below may be through the Fund's direct investments or indirect through the Fund's investments in the underlying ETFs. Fund Shares will change in value, and you could lose money by investing in the Fund.
Risk Not Insured [Member]
Prospectus [Line Items]
Risk [Text Block]	An investment in the Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
Risk Nondiversified Status [Member]
Prospectus [Line Items]
Risk [Text Block]	Non-Diversification Risk: As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of Fund Shares may be more volatile than the values of shares of more diversified funds.
