Our Process

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 Global Opportunities fund.

Top 10 Holdings and Sector Weightings as a % of Total Net Assets

The Oberweis Funds releases the top 10 holdings as of the most recent quarter-end after a 60-day lag. A complete list of holdings can be obtained by contacting a shareholder services representative after the aforementioned 60-day delay periods.

The Oberweis Funds invest primarily in small-cap companies, which may have volatile price movements. Continuous publication of the Funds’ current holdings has the potential to affect trading volume and the prices of the securities in which the Funds invest. By delaying the release of the holdings, Oberweis may be able to deter front running by traders who could impair our ability to build positions in our best ideas at the best prices.

Portfolio holdings are subject to change at any time. References to specific securities should not be construed as a recommendation to buy or sell and should not be assumed profitable.
