| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? Key contributors to (↑) and detractors from (↓) performance, relative to the S&P 500 ® • The Fund invests in a blend of Stock Portfolio — the Fund’s equity allocation — and Core Bond Portfolio — the Fund’s fixed-income allocation ↓ Core Bond Portfolio underperformed the Index and detracted from Index-relative returns during the period — but outperformed the Secondary Index ↓ An underweight exposure to agency mortgage-backed securities (MBS), yield-curve positioning, and the use of derivatives detracted from returns during the period ↑ Bond selections ― notably in investment-grade corporate bonds ― and sector allocations ― notably an overweight exposure to commercial MBS ― aided returns ↑ Stock Portfolio outperformed the Index; an overweight position in artificial intelligence chipmaker NVIDIA Corp. contributed to Index-relative returns ↑ Among sectors, stock selections and underweight exposures to health care and consumer staples, and stock selections in information technology, helped returns ↓ An overweight position in energy exploration and production firm ConocoPhillips fell in value as global energy demand and oil prices weakened during the period ↓ Among sectors within the Index, the Fund’s stock selections in the energy and real estate sectors detracted from Index-relative performance during the period |

| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? Key contributors to (↑) and detractors from (↓) performance, relative to the S&P 500 ® ↓ Not owning semiconductor maker NVIDIA Corp. or Facebook parent Meta Platforms Inc. hurt relative returns as both stocks performed well. Both firms pay nominal dividends, but did not meet the Fund’s criteria for investing in stocks that demonstrate the ability to produce attractive levels of dividend income over time ↓ An overweight position in CDW Corp., a distributor of technology products and services, lost value as demand from small- and mid-size businesses declined ↓ Among sectors, stock selections and underweight exposures to information technology and communication services, and an overweight in health care hurt returns ↑ In contrast, an overweight position in Broadcom Inc. aided returns as its stock price doubled on AI-driven demand for its semiconductor and software products ↑ An overweight position in global retail and grocery giant Walmart Inc. rose in value as its core U.S. retail business gained market share during the period ↑ An overweight position in paper products firm International Paper Co. rose in value as its new CEO cut costs and employed new strategies that investors favored ↑ Among sectors, stock selections in materials and consumer staples, and stock selections and an underweight exposure to real estate helped Index-relative returns |
