Frequently Asked Questions — BERKSHIRE FUNDS
What type of mutual fund is BERKSHIRE FUNDS?
BERKSHIRE FUNDS is a SEC-registered Equity fund, with $277M in assets under management. Equity funds invest primarily in a diversified portfolio of stocks and equities, aiming for long-term capital appreciation. They carry higher market risk than bond or money market funds but historically offer stronger long-term returns. Equity mutual funds can be further classified as large-cap, mid-cap, small-cap, growth, value, or sector-specific depending on their investment mandate. As of its latest SEC N-PORT filing, BERKSHIRE FUNDS holds 92 portfolio positions, all detailed in the holdings table on this page.
What are BERKSHIRE FUNDS's assets under management (AUM)?
BERKSHIRE FUNDS has $277M in assets under management (AUM) according to its most recent SEC N-PORT filing on StockSifting. AUM represents the total market value of all securities and other assets held by the fund as of the report date. A larger AUM generally signals a more established fund with greater institutional adoption, more trading liquidity, and potentially lower per-unit operational costs due to economies of scale. AUM changes daily as market prices fluctuate and as investors purchase or redeem fund shares — the figure shown here reflects the most recently available N-PORT disclosure, not the current real-time value. For the live figure, consult the fund's official website or its latest SEC EDGAR filing.
What are BERKSHIRE FUNDS's top holdings?
According to BERKSHIRE FUNDS's most recent SEC N-PORT filing, the fund's largest holdings by portfolio weight include Lumentum Holdings Inc., Coherent Corp., GE Vernova Inc. , among others. The complete list of all 92 holdings — including CUSIP, asset type, portfolio weight percentage, dollar value, and share quantity — is available in the holdings table above. 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 BERKSHIRE FUNDS's expense ratio?
Expense ratio data for BERKSHIRE FUNDS is not currently available in StockSifting's database. 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 BERKSHIRE FUNDS's SEC filings?
BERKSHIRE FUNDS is required to file monthly portfolio reports (Form N-PORT) with the U.S. Securities and Exchange Commission (SEC). Its SEC Central Index Key (CIK) is 0001030979. You can access all of BERKSHIRE FUNDS's SEC filings — including N-PORT holdings disclosures, annual reports (Form N-CEN), and registration statements — directly on SEC EDGAR (CIK: 0001030979). N-PORT filings disclose the fund's complete portfolio holdings, fair value measurements, and certain risk metrics as of each filing period end date. StockSifting automatically parses these filings to populate the holdings table, AUM figures, and expense ratio displayed on this page, making the raw EDGAR data accessible without needing to download and parse XML files manually.
How current is BERKSHIRE FUNDS's holdings data on StockSifting?
Holdings data for BERKSHIRE 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.
