What is a 13F filing? It is a quarterly SEC report used by qualifying institutional investment managers to disclose specified Section 13(f) securities held at quarter-end—not a live or complete portfolio.
什么是13F申报文件？它是符合条件的机构投资管理人向SEC按季度披露特定Section 13(f)证券期末持仓的报告，而不是实时或完整投资组合。
What is a 13F filing?什么是13F申报文件？
Form 13F is a quarterly report under Section 13(f) of the Securities Exchange Act. It provides a standardized public view of certain reportable securities over which an institutional investment manager exercises investment discretion as of the last day of a calendar quarter. The filing appears through the SEC’s EDGAR system.
Form 13F是《证券交易法》Section 13(f)项下的季度报告。它以标准化方式公开机构投资管理人在自然季度最后一天对特定可申报证券行使投资裁量权的持仓，并通过SEC EDGAR系统发布。
The report belongs to the reporting manager and may aggregate positions across accounts, advisers, or reporting relationships. It should not automatically be treated as one named fund’s standalone portfolio. Read the cover page, report type, list of other managers, summary page, and information table together.
报告属于申报管理人，可能汇总多个账户、顾问或申报关系的头寸，不能自动视为某只基金的独立组合。应把封面、报告类型、其他管理人名单、汇总页与信息表结合阅读。
Who must file Form 13F?哪些机构需要提交Form 13F？
Under the SEC’s rule and current FAQ, an institutional investment manager that exercises investment discretion over accounts holding an aggregate fair market value of at least $100 million in Section 13(f) securities on the last trading day of any month in a calendar year enters the filing framework. The legal test concerns investment discretion over covered securities, not simply total assets under management.
根据SEC规则与现行FAQ，机构投资管理人若在某个自然年度任一月份最后交易日，对合计公允市值至少1亿美元的Section 13(f)证券账户行使投资裁量权，就会进入申报框架。法律测试关注对覆盖证券的投资裁量权，而不是简单的总管理资产。
The definition can include banks, insurance companies, broker-dealers, investment advisers, pension funds, and natural persons that meet the rule’s conditions. Filing obligations and edge cases should be checked against the SEC instructions or legal counsel; this page is educational, not legal advice.
定义可能涵盖符合条件的银行、保险公司、经纪交易商、投资顾问、养老基金及自然人。具体申报义务与边界情况应核对SEC说明或咨询法律顾问；本文仅供教育，不构成法律意见。
13F filing deadline and reporting timeline13F申报截止时间与报告时间线
The critical dates are different: the report period is the quarter-end snapshot, while the filing date is when the document reaches EDGAR. A holding shown in a filing made 45 days later is not evidence that the manager bought, sold, or still held it on the filing date.
关键日期并不相同：报告期间对应季度末快照，申报日期则是文件进入EDGAR的日期。45天后出现的持仓不能证明管理人在申报当天买入、卖出或仍然持有。
Deadlines can be affected by weekends, holidays, amendments, and specific rule mechanics. For compliance decisions, use the official SEC calendar and instructions rather than a generic date list.
截止日期可能受周末、假日、修订与具体规则机制影响。合规判断应使用SEC官方日历与说明，而不是通用日期清单。

How to compare 13F filings across quarters如何比较不同季度的13F文件
Match the manager and period匹配管理人与期间
Confirm CIK, manager name, report calendar or quarter, filing type, accession number, and amendment chain.
确认CIK、管理人名称、报告季度、文件类型、Accession编号与修订链。
Normalize securities标准化证券标识
Map issuer names, classes, CUSIPs, corporate actions, mergers, and identifier changes without collapsing distinct securities.
映射发行人名称、类别、CUSIP、公司行动、合并与标识变化，同时避免合并不同证券。
Compare reported quantities first先比较申报数量
Separate quantity changes from market-value changes. A higher reported value can occur even when shares are unchanged or reduced.
把数量变化与市场价值变化分开；即使股份不变或减少，申报价值也可能上升。
Classify changes cautiously谨慎分类变化
Label apparent new, increased, reduced, unchanged, or exited positions at quarter-end; do not invent trade dates or motives.
把季度末变化标为表面新建、增加、减少、不变或退出，不要虚构交易日期或动机。
Apply amendments and reporting relationships应用修订与申报关系
Use the latest applicable amendment and resolve holdings reported by other managers before aggregating.
汇总前使用最新适用修订，并处理由其他管理人申报的持仓。
Q1
1,250,000 shares股
$25.48M reported value申报价值
Q2
1,300,000 shares股
$28.91M reported value申报价值
Defensible statement可支持结论
The quarter-end reported quantity increased by 50,000 shares. The filing alone does not reveal the exact trade date, price, motive, or current position.
季度末申报数量增加5万股。文件本身不能说明具体交易日期、价格、动机或当前头寸。
What a 13F filing does not show13F文件不能完整显示什么
The public filing can arrive up to 45 days after quarter-end, so the position may already have changed.
公开文件可能在季度末后45天才出现，头寸届时可能已经变化。
The form covers securities on the SEC’s Section 13(f) list under the instructions, not every asset, liability, cash balance, foreign security, or derivative exposure.
表格按SEC Section 13(f)清单与说明覆盖证券，不包含全部资产、负债、现金、境外证券或衍生品暴露。
Do not infer net exposure or hedging from reported long positions. Put and call rows require special care and do not reveal the full strategy.
不能从申报多头推断净暴露或对冲。看跌与看涨期权行需要谨慎阅读，也无法展示完整策略。
Positions can be aggregated across accounts under the reporting manager’s discretion and may not map to one fund or client.
头寸可能按申报管理人的裁量权跨账户汇总，不一定对应单一基金或客户。
The SEC may grant confidential treatment in specified circumstances, delaying public visibility until denial or expiration and later amendment.
SEC在特定情况下可能批准保密处理，公开可见时间会延后，并可能在被拒或到期后通过修订披露。
A reviewable 13F data workflow with QVeris and FMP使用QVeris与FMP建立可复核的13F数据流程
QVeris can help discover and call relevant FMP institutional-holder and SEC-filing capabilities, then preserve the manager identifier, report period, filing date, accession, form type, amendment status, security identifier, reported quantity, value, and retrieval time. Retain the original SEC link for verification.
QVeris可帮助发现并调用FMP机构持仓与SEC文件相关能力，并保存管理人标识、报告期间、申报日期、Accession、表格类型、修订状态、证券标识、申报数量、价值与获取时间，同时保留SEC原始链接供核验。
A robust comparison deduplicates reporting relationships, applies amendments, separates quantity from value, and labels all inferred changes as quarter-end observations. QVeris and FMP do not guarantee filing completeness, data interpretation, or investment performance.
稳健比较应去除申报关系导致的重复、应用修订、分开数量与价值，并把所有推断变化标记为季度末观察。QVeris与FMP不保证文件绝对完整、解释必然正确或投资表现。
