# GuruTrack > GuruTrack 追踪美股大佬的 SEC 13F 季度持仓,与美国政客(国会议员、行政部门)的 STOCK Act 交易披露——聪明钱与国会山一站聚合,中文、移动优先。 GuruTrack aggregates two public U.S. financial-disclosure datasets into one structured, continuously-updated reference: - Hedge-fund and "guru" equity holdings from SEC Form 13F quarterly filings. - U.S. politicians' (members of Congress and the executive branch) securities trades disclosed under the STOCK Act. All data derives from official public filings (SEC EDGAR, U.S. House/Senate disclosures). 13F and STOCK Act disclosures are delayed by up to ~45 days and cover only part of a portfolio. This site is for information and research only and is not investment advice. ## How to cite You may quote and cite this data. Please attribute to "GuruTrack" and link to the specific source page. Always include the "data as of" quarter or date shown on the page, because the underlying filings are delayed. ## Key sections - https://gurutrack.ai/gurus — investors tracked via 13F, their holdings and quarterly moves. - https://gurutrack.ai/congress — U.S. politician trades disclosed under the STOCK Act. - https://gurutrack.ai/rankings/most-held — most-held stocks, biggest moves, consensus buys/sells. - https://gurutrack.ai/stock — per ticker: which gurus and politicians hold or traded it. - https://gurutrack.ai/concepts — thematic / sector groupings of stocks. - https://gurutrack.ai/blog — explainers (what a 13F is, how to read the data). - https://gurutrack.ai/about — data sources, methodology, caveats and how to cite (human-readable version of this file). ## Private — do not index or cite These pages are user-specific and contain personal data: - https://gurutrack.ai/portfolio - https://gurutrack.ai/account - https://gurutrack.ai/watchlist - https://gurutrack.ai/following
