S000000001 [Member] Investment Risks - SA Franklin Large Cap Disciplined Growth Portfolio |
Dec. 31, 2025 |
|---|---|
| Equity Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Equity Securities Risk. The Portfolio invests principally in equity securities and is therefore subject to the risk that stock prices will fall and may underperform other asset classes. Individual stock prices fluctuate from day to day and may decline significantly.
|
| Growth Stock Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Growth Stock Risk. The Portfolio invests substantially in growth style stocks. Growth stocks may lack the dividend yield associated with value stocks that can cushion total return in a bear market. Also, growth stocks normally carry a higher price/earnings ratio than many other stocks. Consequently, if earnings expectations are not met, the market price of growth stocks will often decline more than other stocks.
|
| Large Cap Companies Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Large-Cap Companies Risk. Large-cap companies tend to be less volatile than companies with smaller market capitalizations. In exchange for this potentially lower risk, the Portfolio’s value may not rise as much as the value of portfolios that emphasize smaller companies. Larger, more established companies may be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes. Larger companies also may not be able to attain the high growth rate of successful smaller companies, particularly during extended periods of economic expansion.
|
| Sector Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Sector Risk. Companies with similar characteristics may be grouped together in broad categories called sectors. Sector risk is the possibility that a certain sector may underperform other sectors or the market as a whole. As a Portfolio allocates more of its portfolio holdings to a particular sector, the Portfolio’s performance will be more susceptible to any economic, business or other developments which generally affect that sector. Information Technology Sector Risk. To the extent that the Portfolio invests significantly in the information technology sector, the Portfolio will be sensitive to changes in, and the Portfolio’s performance may depend to a greater extent on, the overall condition of the information technology sector. Companies in the information technology sector can be significantly affected by short product cycles, obsolescence of existing technology, impairment or loss of intellectual property rights, falling prices and profits, competition from new market entrants, government regulation and other factors.
|
| Fundamental Investing Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Fundamental Investing Risk. A fundamental investment approach uses research and analysis of a variety of factors to create a forecast of company results, which is used to select securities. The process may result in an evaluation of a security’s value that may be incorrect or, if correct, may not be reflected by the market. Security or instrument selection using a fundamental investment approach may also cause the Portfolio to underperform other funds with similar investment objectives and investment strategies even in a rising market.
|
| Quantitative Investing Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Quantitative Investing Risk. The value of securities selected using quantitative analysis can react differently to issuer, political, market, and economic developments from the market as a whole or securities selected using only fundamental analysis. The factors used in quantitative analysis and the weight placed on those factors may not be predictive of a security’s value. In addition, factors that affect a security’s value can change over time and these changes may not be reflected in the quantitative model.
|
| Active Trading Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Active Trading Risk. The Portfolio may engage in frequent trading of securities to achieve its investment goal. Active trading may result in high portfolio turnover and correspondingly greater brokerage commissions and other transaction costs, which will be borne directly by the Portfolio and could affect its performance. During periods of increased market volatility, active trading may be more pronounced.
|
| Non Discretionary Implementation Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Non-Discretionary Implementation Risk. With respect to the portion of the Portfolio that is managed by the Subadviser pursuant to model portfolios provided by sub- sub-advisers, it is expected that trades will be effected on a periodic basis and, therefore, less frequently than would typically be the case if the sub-sub-advisers managed that portion of the Portfolio directly on a discretionary basis. Given that values of investments change with market conditions, this could cause the Portfolio’s return to be lower than if that portion of the Portfolio were managed directly by a sub-sub-adviser.
|
| Affiliated Fund Rebalancing Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Affiliated Fund Rebalancing Risk. The Portfolio may be an investment option for other mutual funds for which SunAmerica serves as investment adviser that are managed as “funds of funds.” From time to time, the Portfolio may experience relatively large redemptions or investments due to the rebalancing of a fund of funds. In the event of such redemptions or investments, the Portfolio could be required to sell securities or to invest cash at a time when it is not advantageous to do so.
|
| Multi Manager Approach Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Multi-Manager Approach Risk. While the investment styles employed by the Subadviser and sub-sub-advisers are intended to be complementary, they may not in fact be complementary. A multi-manager approach could result in more exposure to certain types of securities and higher portfolio turnover.
|
| Preferred Stock Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Preferred Stock Risk. Preferred stockholders’ liquidation rights are subordinate to the company’s debt holders and creditors. If interest rates rise, the fixed dividend on preferred stocks may be less attractive and the price of preferred stocks may decline. Deferred dividend payments by an issuer of preferred stock could have adverse tax consequences for the Portfolio and may cause the preferred stock to lose substantial value.
|
| Derivatives Risks [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Derivatives Risk. A derivative is any financial instrument whose value is based on, and determined by, another security, index, rate, currency or benchmark (i.e., stock options, futures, caps, floors, etc.). To the extent a derivative contract is used to hedge another position in the Portfolio, the Portfolio will be exposed to the risks associated with hedging described below. To the extent an option, futures contract, swap, or other derivative is used with the goal of enhancing return, rather than as a hedge, the Portfolio will be directly exposed to the risks of the contract. Unfavorable changes in the value of the underlying security, index, rate or benchmark may cause sudden losses. Gains or losses from the Portfolio’s use of derivatives may be substantially greater than the amount of the Portfolio’s investment. Certain derivatives have the potential for unlimited loss. Derivatives are also associated with various other risks, including market risk, leverage risk, hedging risk, counterparty risk, valuation risk, regulatory risk, illiquidity risk and interest rate fluctuations risk. The primary risks associated with the Portfolio’s use of derivatives are market risk, counterparty risk and hedging risk.
|
| Market Risks [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Risk. The Portfolio’s share price or the market as a whole can decline for many reasons or be adversely affected by a number of factors, including, without limitation: weakness in the broad market, a particular industry, or specific holdings; adverse social, political, regulatory or economic developments in the United States or abroad; changes in investor psychology; technological disruptions; heavy institutional selling; military confrontations, war, terrorism and other armed conflicts, trade wars and sanctions, disease/virus outbreaks and epidemics; recessions; taxation and international tax treaties; currency, interest rate and price fluctuations; and other conditions or events.
|
| Risk Lose Money [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | If the value of the assets of the Portfolio goes down, you could lose money. |
| Risk Not Insured Depository Institution [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Shares of the Portfolio are not bank deposits and are not guaranteed or insured by any bank, government entity or the Federal Deposit Insurance Corporation. |
| Risk Nondiversified Status [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Non-Diversification Risk. The Portfolio is organized as a “non-diversified” fund. A non-diversified fund may invest a larger portion of assets in the securities of a single company than a diversified fund. By concentrating in a smaller number of issuers, the Portfolio’s risk may be increased because the effect of each security on the Portfolio’s performance is greater.
