For the live figure, consult the fund's official website or its latest SEC EDGAR filing.

Holdings data is sourced directly from SEC EDGAR N-PORT filings and reflects the fund's positions as of the report date shown at the top of this page. Due to the 60-day SEC disclosure lag, these positions may differ from the fund's current portfolio. For the latest holdings before public release, refer to SEC EDGAR directly.
What is OBERWEIS FUNDS's expense ratio?

The expense ratio is the annual fee charged by a mutual fund as a percentage of your investment, covering management fees and operational costs. It is one of the most important factors affecting net long-term returns — lower expense ratios allow more of a fund's gross performance to flow through to investors. For the most accurate and current expense ratio, refer to the fund's official prospectus or its SEC EDGAR filings. You can also contact us if you believe this data should be present.
Where can I find OBERWEIS FUNDS's SEC filings?

How current is OBERWEIS FUNDS's holdings data on StockSifting?
Holdings data for OBERWEIS FUNDS on StockSifting is sourced from its most recent SEC EDGAR N-PORT filing. Under SEC rules, registered investment companies must file N-PORT reports monthly, but these are made publicly available approximately 60 days after the reporting period end date. This means the holdings shown on this page reflect the fund's portfolio from roughly two months prior — not today's exact positions. The Report date displayed at the top of this page indicates exactly when the underlying data was current. If the fund has made significant portfolio changes since that date — responding to market events, earnings releases, or macro shifts — those changes will not be reflected here until the next N-PORT filing is released. For the most up-to-date holdings before the public disclosure window, refer to the fund's official website or SEC EDGAR directly. StockSifting is best used for fundamental research and historical portfolio analysis, not real-time trading decisions.
