Latest complete 13F quarter

Q2 2026

13F shows holdings on the last day of each quarter, and institutions have 45 days to file it, so a holding can be 45 days old by the time it appears. It covers only long positions in 13(f) securities, mainly US-listed stocks, ETFs and listed options. Short positions, cash, most bonds and shares listed only abroad are left out, so a 13F is not the whole portfolio. A quarter counts as complete once the filing deadline has passed and the filings are loaded; until then, its numbers look too low.

13F reports a market value and a number of shares for each holding, not a price. Where Livermore shows a price for a 13F holding, it is the value divided by the shares: the price the filer used at the end of the quarter. It is not what the institution paid, and it can differ from the closing price.

Institutions file at different times during the 45 days. When Livermore compares two quarters, a position counts as sold out only if the institution filed the later quarter without it. Institutions that have not filed yet are marked as not filed and are left out of sold-out counts and changes in the number of holders.

A holder's stake is as of its latest 13D or 13G filing: 13G holders only amend after a material change, holders stop filing after a company is acquired or delisted, and older free-form filings (before December 18, 2024) carry no stake at all, so those holders are not counted as current 5% holders. In a group filing each member reports the shares it counts as its own, so Livermore shows the largest single stake rather than a sum. Form 144 is a notice of a planned sale, not a completed one; notices whose market value is clearly misreported are flagged and left out of lists and totals.

Politician trade lists, counts and totals include only listed securities by default: stocks (including ADRs), ETFs and options. Treasury bills, bonds, private companies and other assets appear when you choose All assets. Members of Congress report each trade as an amount range, such as $1,001-$15,000, not an exact value. Where Livermore adds trades up, it counts the midpoint of each range and an “Over $X” range as $X, so estimated volumes are rough sizes. The law allows up to 45 days to report a trade; the filing delay is counted from the trade to its first report, and a trade date after the filing date is treated as a typing error. Amendments replace the trades they correct, a trade reported twice is counted once, and scanned or paper reports are listed but not read.

Statements are as filed in each period's original report (or its amendment), in the currency the company reports in; amounts in other currencies get an approximate US dollar figure at FRED H.10 rates. There is no 10-Q for the fourth quarter, so Q4 is the full year minus the first three quarters, and single-quarter cash flows are derived from year-to-date figures; derived values are marked. EPS is not adjusted for later stock splits. Foreign companies that file Form 20-F or 40-F have annual statements only. The reported date is the first 8-K with Item 2.02 after the period ended.

Short interest (shares still sold short on a settlement date) and daily short volume (short sales executed each day off the exchanges) measure different things: the short volume ratio is not a sentiment gauge, because market makers' short sales are usually about half of off-exchange volume. Days to cover is FINRA's figure; FINRA caps it at 999.99. Livermore shows no stock prices and has no float data, so there is no short interest as a percent of float. Fails-to-deliver come from the SEC about two weeks late, and ATS volume from FINRA two to four weeks late.

Form 4 is due within two business days after a trade, so insider data trails the trade by up to two business days. Livermore shows the delay between the trade date and the filing date, and marks filings that came in after the deadline as late.

Trades made under a Rule 10b5-1 plan were scheduled in advance, often months earlier, so they say little about what the insider thinks today. Since April 2023, Form 4 has a checkbox for these trades, and Livermore labels them 10b5-1. Older filings have no such checkbox, so older planned trades can't be told apart.

13F identifies securities by CUSIP, not by ticker. Livermore matches CUSIPs to tickers using several sources; holdings that can't be matched are shown with their CUSIP and the name given in the filing.

Numbers are shown as filed. When a stock splits (including reverse splits), the earlier quarter's share count is converted at the split ratio before two quarters are compared, so a split doesn't look like buying or selling; the share counts themselves stay as filed. Livermore doesn't convert between ADSs and ordinary shares; the security title from the filing is shown so you can tell them apart.

Amended filings are taken into account: a Form 4/A replaces the original in totals, and 13F amendments are applied in the order they were filed.

Values that look like filing errors, such as an implausible price, are kept as filed rather than silently removed, and so are prices that insiders of some foreign companies report in their local currency instead of US dollars. These rows are flagged and left out of rankings by value, such as the largest purchases, so a single typo can't top a list.

Livermore does not show stock prices. The only prices shown come from the filings themselves: the transaction price on Form 4, value divided by shares on 13F, and the previous-day closing price the SEC publishes with fails-to-deliver. The price charts on stock pages are embedded from TradingView. The market cap on stock pages is calculated from the latest daily close and the share count on the 10-K or 10-Q cover page, but the close itself is not shown. Companies whose cover page lists each share class separately, and foreign companies whose US shares are ADSs, have no market cap.
