The investment seeks long-term capital growth... Show more
PRJIX is the I Class share of the T. Rowe Price New Horizons Fund, one of the oldest and best-known growth-oriented mutual funds in the United States. Although it is sometimes grouped with exchange-traded funds (ETFs) in screening tools, it is technically an open-end mutual fund: shares are bought and sold directly through T. Rowe Price or financial intermediaries and are priced once daily at the fund's net asset value (NAV). Investors follow PRJIX because it offers professionally managed, diversified exposure to smaller, faster-growing companies — an area of the market that historically offers high growth potential but also carries elevated volatility.
Investment objective and strategy. The New Horizons Fund seeks long-term capital growth by investing primarily in the common stocks of small, rapidly growing companies. Its managers favor businesses identified early in their corporate life cycle, before they become widely recognized by the investment community. The fund may also hold companies with the potential to accelerate earnings growth because of new management, innovative products, or structural changes in the economy.
Active management. Unlike a passively managed index fund, the New Horizons Fund relies on bottom-up, research-driven stock selection by T. Rowe Price's portfolio management team. Because it does not mechanically track an index, the fund is benchmarked against the Russell 2000 Growth Index as a performance reference rather than as a replication target.
Issuer and share classes. The fund is issued by T. Rowe Price, a Baltimore, Maryland-based asset manager founded in 1937. The original Investor Class dates back to 1960, while the I Class share (PRJIX) launched on August 28, 2015. Related share classes include the Investor Class (PRNHX) and the Z Class (TRUZX). The I Class is generally intended for institutions and typically carries a higher minimum investment than the Investor Class.
Holdings and allocation. The portfolio spans roughly 350 individual securities, keeping any single position relatively small — its top ten holdings have typically represented only about 20% of assets. Recent largest holdings have included Dutch Bros (BROS), Guardant Health (GH), Kymera Therapeutics (KYMR), Entegris (ENTG), Natera (NTRA), Lattice Semiconductor (LSCC), Old Dominion Freight Line (ODFL), argenx (ARGX), Teledyne Technologies (TDY), and SiteOne Landscape Supply (SITE). Sector exposure has leaned heavily toward industrials, health care, and information technology, with smaller allocations to energy, materials, consumer discretionary, and financials.
Costs and turnover. The I Class carries a net expense ratio of approximately 0.66%, meaning that for every $1,000 invested, about $6.60 is deducted annually for management and operating costs. Turnover has historically been elevated — often around 90% in recent periods — reflecting an actively traded, growth-oriented approach.
PRJIX attracts attention because it offers a professionally managed gateway to the small- and mid-cap growth segment, which can be difficult for individual investors to research and access efficiently. The fund's investment strategy targets companies in their early growth phase, when earnings potential may be highest but information is often limited. Its broad diversification across hundreds of holdings, combined with a deep, analyst-driven research platform, is intended to manage some of the risk inherent in smaller-capitalization investing. Because it provides broad sector exposure to innovation-driven areas such as health care and technology, the fund is frequently used by long-term investors seeking a growth-oriented complement to large-cap core holdings.
Investors should understand several key risks before considering this fund. Small- and mid-cap risk: smaller companies tend to be more volatile and less liquid than large-cap stocks. Growth-stock risk: growth equities can experience sharp price swings and periods of underperformance relative to value stocks or the broader market. Active-management risk: the portfolio may underperform its benchmark or peers. Sector concentration: meaningful exposure to health care and technology means the fund can be disproportionately affected by regulatory changes or industry-specific setbacks. Turnover and tax considerations: high turnover can generate capital-gain distributions that create tax liabilities for taxable accounts. Finally, the fund's expense ratio and institutional share-class requirements should be weighed against lower-cost index alternatives.
