Jacob Funds, a mutual fund company, released its first-quarter 2026 investor letter. A copy of the letter can be downloaded here. The Fund started the year optimistically, expecting fiscal and monetary policies to boost an economy showing mixed signals. However, rapid AI developments and a Middle East conflict caused one of the worst quarters since COVID. Market turbulence led to widespread tech sell-offs, blurring lines between at-risk and AI-benefiting firms. AI prompts critical long-term questions for the tech industry, with emerging agentic AI promising a new wave of innovation similar to the late 1990s dot-com boom. Recent market weakness allowed the Fund to invest in promising beneficiaries at better prices, creating an opportunity to pivot into names with potential for rapid growth and profits as agentic AI moves from niche to broad adoption. Please review the Fund’s top five holdings to gain insights into their key selections for 2026.

Jacob Funds stated the following regarding Vir Biotechnology, Inc. (NASDAQ:VIR) in its Q1 2026 investor letter:
“The Jacob Small Cap Growth Fund also added a position in Circle Internet Group, as well as Vir Biotechnology, Inc. (NASDAQ:VIR). Vir Biotechnology is a leader in the exciting field of immunotherapy, and specifically a therapy known as Bispecific T-Cell engagers, or BiTEs. BiTEs hold a tremendous amount of promise in oncology, as the therapy helps recruit a patient’s innate immune system to kill cancer cells, as well as for infectious diseases, like hepatitis delta and HIV. Vir’s approach is to mask their T-Cell engagers with a proprietary technology exclusively licensed from Sanofi, so that the therapy is only activated when it encounters diseased cells, which should increase the effectiveness of the treatment while minimizing off target toxicity, a major problem encountered by other BiTEs in development. Vir recently completed a large collaboration deal with Astellas following the release of successful Phase 1 data for its drug in prostate cancer, which will give them enough cash to fund clinical trials for the next several years.”
