JANUS HENDERSON RESEARCH FUND CLASS T (JAMRX) Exchange: NMFQS

The Fund pursues its investment objective by investing primarily in common stocks selected for their growth potential. The Fund may invest in companies of any size, from larger, well-established companies to smaller, emerging growth companies.Janus Capital’s equity research analysts, overseen by the Portfolio Oversight Team led by Janus Capital’s Director of Research Carmel Wellso (the “Research Team”), select investments for the Fund that represent the Research Team’s high-conviction investment ideas in all market capitalizations and styles. The Research Team, comprised of sector specialists, conducts fundamental analysis with a focus on “bottom up” research, quantitative modeling, and valuation analysis. Using this research process, analysts rate their stocks based upon attractiveness. Stocks considered to be attractive may have all or some of the following characteristics: (i) good and preferably growing free cash flow, (ii) strong and defensible market position, (iii) healthy risk/return profile, (iv) exemplary governance, and (v) attractive valuation. Analysts bring their high-conviction ideas to their respective sector teams. Sector teams compare the appreciation and risk potential of each of the team’s high-conviction ideas and construct a sector portfolio that is intended to maximize the best risk-reward opportunities. Although the Research Team may find high-conviction investment ideas anywhere in the world, the Research Team emphasizes investments in securities of U.S.-based issuers.Positions may be sold when, among other things, there is no longer high conviction in the return potential of the investment or if the risk characteristics have caused a re-evaluation of the opportunity. This may occur if the stock has appreciated and reflects the anticipated value, if another company represents a better risk-reward opportunity, or if the investment’s fundamental characteristics deteriorate. Securities may also be sold from the portfolio to rebalance sector weightings.Ms. Wellso oversees the investment process and is responsible for the day-to-day management of the Fund. It is expected that the Fund will be broadly diversified among a variety of industry sectors. The Fund intends to be fully invested under normal circumstances. However, under unusual circumstances, if the Research Team does not have high conviction in enough investment opportunities, the Fund’s uninvested assets may be held in cash or similar instruments.The Fund may lend portfolio securities on a short-term or long-term basis, in an amount equal to up to one-third of its total assets as determined at the time of the loan origination.
