Small-Cap Opportunities


Realize a total return exceeding the Russell 2000 Growth Index over a full market cycle.

Investment Strategy

The Oberweis Small-Cap Opportunities strategy seeks to capitalize on the exceptional growth potential of smaller companies that are often misunderstood by traditional Wall Street research analysts. The Oberweis Small-Cap Opportunities strategy generally invests in companies (with market capitalizations within the range of the holdings in the Russell 2000 Index at the time of purchase) where our expectations for earnings growth differ from consensus expectations. These companies often boast exciting products and/or services, a strong and sustainable competitive position, and the potential for upward revisions in earnings expectations in the future. Our fundamental research process is specifically designed to efficiently identify such opportunities.


  • Potential for significant alpha over a full market cycle
  • Disciplined and repeatable investment process managed by a passionate and experienced investment team
  • Fundamental research process specifically designed to efficiently discover smaller cap companies that are misunderstood by traditional Wall Street research analysts
  • Exposure to smaller cap companies offering the potential for earnings growth that differs from consensus expectations
  • Diversified portfolio with a focus on risk management

Our Process

Our process rests on our firmwide commitment to uncovering and capitalizing on the persistent and recurring stock pricing inefficiencies in global equities caused by a lag in investor response to new information. This lag in recognizing the catalysts likely to positively impact future earnings growth drives the security selection across all our strategies and mutual funds. The criteria used within each product, however, can differ. This is how our investment team implements our philosophy in the Small-Cap Opportunities strategy.

*OAM Small-Cap Opportunities composite inception date: 9/15/96.  From inception to April 30, 2009, the composite’s name was Smid-Cap Growth Equity.

The Russell 2000 Index measures the performance of approximately 2,000 companies with small market capitalizations. The Russell 2000 Growth Index measures the performance of those Russell 2000 companies with higher price-to-book ratios and higher forecasted earnings growth rates. Each index is an unmanaged group of stocks, whose performance does not reflect the deduction of fees, expenses, or taxes. You cannot invest directly in these indexes.

Net-of-fee composite returns are calculated using the highest model investment advisory fees applicable to portfolios within the composite. Advisory fees are disclosed in Part II of Form ADV. Performance is historical and includes the reinvestment of dividends and other income. Performance is calculated and presented in U.S. dollars. Past performance is not necessarily indicative of future results.
