Fund profile

As filed in the prospectus · 2026 Q1

Janus Henderson Research Fund seeks long-term growth of capital.

Strategy · summarised

The fund invests primarily in common stocks of any size selected through fundamental bottom-up research by its central research team, which rates stocks on characteristics including free cash flow, market position, valuation, and growth potential. The fund is nondiversified, allowing it to hold larger positions in individual securities than a diversified fund would. Because the fund concentrates its holdings, performance depends significantly on the success of a smaller number of positions.

These classes hold the same portfolio, so the 9.19pp spread over 5 years is the cost difference between them — roughly 1.84pp a year — not a difference in what they own.

Cumulative return· Jul 2023 – Apr 2026

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