About OBSIX

The Oberweis Small-Cap Opportunities Fund Institutional Class is an open-end mutual fund designed to seek capital appreciation by investing primarily in small-cap growth companies. It aims to identify and capitalize on firms with improving growth characteristics, focusing on those with potential for significant long-term increases in market value. The fund typically allocates at least 80% of its assets to equities of companies whose market capitalizations fall within the range defined by the Russell 2000 Growth Index at the time of purchase. Leveraging fundamental analysis, the management emphasizes under-appreciated revenue and earnings growth, as well as catalysts such as positive earnings surprises or inflection points driven by new products or leadership. This approach often leads to a diversified portfolio with notable exposure to the technology, healthcare, consumer cyclical, and industrial sectors. Managed by Oberweis Asset Management, the fund is supported by a disciplined and experienced investment team committed to uncovering opportunities in smaller, often overlooked companies, aiming to deliver a total return that exceeds the benchmark over a full market cycle.
