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.
