About JAMFX

The Jacob Internet Fund Investor Class is a mutual fund that targets long-term capital growth by investing primarily in companies within the Internet and Internet-related industries. Managed by Jacob Asset Management of New York LLC since its inception in December 1999, the fund allocates at least 80% of its net assets to common stocks or securities convertible into common stock, with a focus on firms that emphasize research and development in proprietary Internet products and services for both consumers and businesses. It maintains flexibility to invest up to 35% of assets in fixed income or debt securities, and may allocate up to 25% of assets to foreign companies, providing global exposure within the sector. The fund is categorized under technology and generally exhibits a small-growth investment style, often selecting smaller and mid-cap firms that may offer high growth potential but also higher volatility and liquidity risks. The Jacob Internet Fund plays a niche role in the market, offering targeted exposure to the dynamic and rapidly evolving Internet sector, and is suited for investors seeking specialized access to innovative technology-driven businesses.
