About OBSOX

Oberweis Small-Cap Opportunities Fund Investor Class is a mutual fund focused on capital appreciation by investing predominantly in the equities of small-cap growth companies. The fund targets firms that, at the time of initial purchase, fall within the market capitalization range of the Russell 2000 Growth Index, emphasizing businesses with the potential for significant long-term growth in market value. Its investment approach is rooted in fundamental research, seeking out companies whose growth prospects may be undervalued or misunderstood by broader market consensus. The portfolio is broadly diversified across sectors such as information technology, consumer discretionary, health care, and industrials, with a concentration on innovative and emerging businesses that may have strong competitive positions or distinctive product offerings. Managed by Oberweis Asset Management, the fund’s disciplined, high-conviction process aims to identify smaller companies likely to benefit from upward earnings revisions and to generate alpha over a full market cycle. The fund is suitable for investors seeking exposure to the dynamic and potentially higher-return segment of small-cap U.S. equities.
