Factors Affecting Performance [Text Block] | Management's Discussion of Fund Performance What impacted Fund performance over the reporting period? The Alger Capital Appreciation Portfolio Class I-2 returned 28.08% for the fiscal six-month period ended June 30, 2024, compared to the 20.70% return of the Russell 1000 Growth Index. During the reporting period, the largest sector weightings were Information Technology and Communication Services. The largest sector overweight was Communication Services and the largest sector underweight was Consumer Staples. Contributors to Performance The Information Technology and Industrials sectors provided the largest contributions to relative performance. Regarding individual positions, NVIDIA Corp.; Microsoft Corp.; Meta Platforms Inc; Amazon.com, Inc.; and Natera, Inc. were the top contributors to absolute performance. Detractors from Performance The Consumer Staples and Financials sectors were the largest detractors from relative performance. Regarding individual positions, Tesla, Inc.; Snowflake, Inc.; Humana Inc.; MongoDB, Inc.; and Adobe Inc. were the top five detractors from absolute performance. U.S. FACTOR IMPACT SUMMARY Soft-landing Narrative Positive During the period, the soft-landing scenario—an economic slowdown without a recession—drove equity markets higher as U.S. GDP for the fourth quarter of 2023 grew 3.4%, exceeding the initial 2.0% consensus, driven by robust consumer spending. AI Enthusiasm Positive Continued anticipation about artificial intelligence drove strong gains for related companies, supported by robust operating results and upward earnings revisions. Elevated Inflation Negative Inflation concerns resurfaced during the first quarter of 2024, with Consumer Price Index (CPI) and Personal Consumption Expenditure Price Index (PCE) readings coming in higher-than-expected. Revised Federal Reserve Rate Cut Expectations Negative Elevated inflation readings during the first quarter of 2024 led to the Federal Reserve postponing an anticipated March rate cut. The revision of the market’s rate cut expectations, initially from a projected six cuts at the beginning of the period down to just one for the year, led to some market volatility in April. | |

Factors Affecting Performance [Text Block] | Management's Discussion of Fund Performance What impacted Fund performance over the reporting period? The Fund returned 1.69% for the fiscal six-month period ended June 30, 2024, compared to the 4.44% return of the Russell 2000 Growth Index. During the reporting period, the largest sector weightings were Information Technology and Health Care. The largest sector overweight was Health Care and the largest sector underweight was Industrials. Contributors to Performance The Consumer Discretionary and Materials sectors provided the largest contributions to relative performance. Regarding individual positions, Wingstop, Inc.; MicroStrategy Incorporated; Viking Therapeutics, Inc.; Manhattan Associates, Inc.; and Q2 Holdings, Inc. were the top five contributors to absolute performance. Detractors from Performance The Health Care and Industrials sectors were the largest detractors from relative performance. Regarding individual positions, Cabaletta Bio, Inc.; 908 Devices Inc.; Sprout Social, Inc.; Xometry, Inc.; and DLocal Limited were the top five detractors from absolute performance. U.S. FACTOR IMPACT SUMMARY Soft-landing Narrative Positive During the period, the soft-landing scenario—an economic slowdown without a recession—drove equity markets higher as U.S. GDP for the fourth quarter of 2023 grew 3.4%, exceeding the initial 2.0% consensus, driven by robust consumer spending. AI Enthusiasm Positive Continued anticipation about artificial intelligence drove strong gains for related companies, supported by robust operating results and upward earnings revisions. Elevated Inflation Negative Inflation concerns resurfaced during the first quarter of 2024, with Consumer Price Index (CPI) and Personal Consumption Expenditure Price Index (PCE) readings coming in higher-than-expected. Revised Federal Reserve Rate Cut Expectations Negative Elevated inflation readings during the first quarter of 2024 led to the Federal Reserve postponing an anticipated March rate cut. The revision of the market’s rate cut expectations, initially from a projected six cuts at the beginning of the period down to just one for the year, led to some market volatility in April. | |
