What's a 13F-HR?
Every institutional investor with over $100M in US equities under management has to file a Form 13F-HR with the SEC every quarter, within 45 days of quarter-end. The filing lists every US-listed long equity position they hold on the last day of the quarter — ticker, share count, dollar value.
The data is 45-90 days old by the time it's public — but it tells you which themes and tickers the smartest money in the world allocated to during that quarter. Useful for direction and confirmation; less useful for timing.
Not investment advice. 13F-HR filings only show long US equity positions — not shorts, options, or international holdings. The funds' actual positioning may differ significantly.
