About OMCIX

Oberweis Micro-Cap Fund Institutional Class is an actively managed mutual fund focused on capital appreciation by investing primarily in micro-cap growth companies. The fund seeks opportunities among companies with market capitalizations typically within the range defined by the Russell Microcap Growth Index, aiming to capture the high growth potential often found in the earliest and most dynamic phases of corporate development. Its strategy relies on a combination of behavioral finance principles and rigorous bottom-up fundamental research to identify firms with improving growth characteristics that may be underappreciated by traditional market analysts. The portfolio is well-diversified, containing around 80-90 holdings, with a notable allocation to sectors such as technology, healthcare, and industrials. The fund is managed by an experienced team with a disciplined and repeatable investment process, and it maintains a focus on risk management. Oberweis Micro-Cap Fund Institutional Class provides investors access to a segment of the equity market considered less efficient and potentially capable of delivering significant alpha over a full market cycle, though it carries higher fees relative to peers.
