Fund profile

As filed in the prospectus · 2026 Q2

Biotechnology Portfolio seeks capital appreciation.

Strategy · summarised

The fund invests at least 80% of assets in common stocks of companies principally engaged in biotechnology research, development, manufacturing, and distribution, including those focused on genetic analysis and genetic engineering, selected through fundamental analysis of financial condition, industry position, and market conditions. The fund may invest in both domestic and foreign issuers. Because the fund's classification of companies as principally engaged in biotechnology relies on asset, income, sales, or profit metrics or third-party industry classifications, the fund's holdings may diverge from what different analysts would consider core biotechnology exposure.

Cumulative return· Jun 2023 – Apr 2026

May 2026 has been filed since the trailing figures were struck, so it is not in the table above or the curve — every figure here shares one cut-off, which is what makes them comparable with other funds.
