- Oberweis Micro-Cap Fund (OBMCX) is an open-end mutual fund that seeks capital appreciation by investing primarily in the common stocks of micro-cap growth companies. The fund, under normal circumstances, allocates at least 80% of its net assets to securities of very small companies with market capitalizations, at the time of purchase, of less than or equal to $600 million or within the range represented by the Russell Microcap Growth Index, whichever is greater; it emphasizes firms demonstrating improving growth characteristics, exciting products or services, sustainable competitive advantages, and potential for upward earnings revisions. Investor Class shares (OBMCX) and Institutional Class shares (OMCIX) are offered, with minimum investments of $1,000 (non-IRA) or $500 (IRA) for OBMCX and $1 million for OMCIX; the fund employs a disciplined, repeatable process blending behavioral finance principles and fundamental bottom-up research to target misunderstood micro-cap opportunities across sectors such as information technology (27.5%), industrials (26.3%), and health care (19.4%) as of June 30, 2025.
Launched on December 29, 1995, the fund is managed by Oberweis Asset Management, Inc., with headquarters at 3333 Warrenville Rd., Suite 500, Lisle, Illinois 60532; it operates within the U.S. equity market, targeting individual and institutional investors seeking exposure to one of the least efficient segments of the market for potential significant alpha generation over full market cycles. The portfolio typically holds 86 stocks with a weighted average market capitalization of $1,982 million and median of $1,342 million as of June 30, 2025, maintaining a cash position of 2.1%, portfolio turnover of 51% in 2024, forward P/E of 21.5x, long-term debt-to-equity of 13.1%, and return on equity of 7.7%. Distributed by Oberweis Securities, Inc., a FINRA and SIPC member, the fund features gross/net expense ratios of 1.47%/1.47% for OBMCX and 1.22%/1.22% for OMCIX as of December 31, 2024, with a contractual fee waiver through April 30, 2026, capping ordinary operating expenses.
In recent developments, the fund reported strong second-quarter 2025 total returns of 15.35% for OBMCX and 15.40% for OMCIX through June 30, 2025, contributing to year-to-date gains of 0.35% and 0.50%, respectively, amid outperformance versus the Russell Microcap Growth Index over 10 years (15.79% annualized for OBMCX); top holdings as of March 31, 2025, included ADMA Biologics, Inc. (5.3%), Imax Corp. (2.6%), and Primoris Services Corp. (2.4%), reflecting a focus on high-conviction positions in dynamic micro-caps. Oberweis Asset Management continues to emphasize risk management in its diversified approach, with no reported major acquisitions, partnerships, or structural changes in the past 1-2 years, maintaining its core strategy amid volatile micro-cap market conditions.
