Factors Affecting Performance [Text Block]

WHAT AFFECTED THE FUND’S PERFORMANCE DURING THE REPORTING PERIOD?

■

Positive investor reactions to a slowing pace of inflation and sustained economic growth led to increased capital asset prices over the reporting period, with equities ending the year at near-record levels. The US Federal Reserve lowered the federal funds interest rate at each of its last three meetings, bringing the effective level down from 5.3% at the beginning of the year to 4.3% as of December 31, 2024. Equities responded favorably to the moves, especially in interest-rate-sensitive sectors. The strength of corporate profits overall has been an important contributor to performance amidst the sustained growth of the US economy. Employment has remained at healthy levels throughout the period, although there have been signs of weakening in the past six months. While the rate of inflation declined during the reporting period, this trend has flattened out in recent months.

■ Relative to the Russell 1000 Growth Index (the Index), security selection within the health care (led by health care equipment and supplies) and consumer staples (distribution and retail and personal care products) sectors, along with the Portfolio’s lack of exposure to the energy and materials sector, contributed positively to returns.

■ While the Portfolio had strong absolute performance for 2024, its relative results fell short of the Index for the period. Compared to the Index, the Portfolio’s stock selection within the information technology (especially software), consumer discretionary (led by textiles, apparel, and luxury goods and broadline retail), and industrials (driven by aerospace and defense) sectors detracted from relative performance.
