Where the data comes from
Every position published here comes from the official registers of the market authorities. Nothing is estimated, nothing is filled in. The table of the last collection shows, for each market, whether that collection succeeded and how far the data goes.

Reuse: each register belongs to its authority. The table of the last collection names each authority and links to its publication. Where a source publishes its data under a licence, it is cited here along with the date our figures stop at.
France: Licence Ouverte 2.0.
Portugal: Reglement (UE) 236/2012, article 6.
The trace of every figure
For each market: the exact file that answered, the time it was read, the number of rows it produced and the number set aside as unreadable. Every figure on the site can be traced back to the file it came from.
The rows set aside are the ones a regulator publishes without a readable position: a below-threshold marker, an empty date cell, a separator line. Their number is shown here: if a source changes format, this column reports it before the totals move.
Nothing is typed in by hand: every total is recomputed from these files at each collection. To redo the count, keep one row per fund, its most recent disclosure, and set aside the ones for which the authority has published an end date. Where the result differs from the figures shown here, the regulator's file prevails.
Reading the registers
A net short position must be reported from 0.1% of capital but is only made public from 0.5%. The totals shown here therefore never represent all short selling.
A fund rediscloses its position at every move. The current position is its most recent disclosure. The earlier ones stay in the history.
The FSMA no longer publishes a file: the positions are read from its public page.
The FMA no longer publishes a file: the positions are read from its public page.
The KNF no longer publishes a file: the positions are read from its public page.
Since 13 July 2026 the FCA no longer publishes the name of the funds, only the total per company.
The Finanstilsynet updates its file only once a month: this market is behind the others by construction, and the "Data up to" column says by how much.
JPX also publishes the positions of securities firms. Its companies compare, its holders do not, so this market is kept out of the ranking of the busiest short sellers.
ASIC has never named the sellers: it publishes one total per company, with a four trading day delay. This market therefore has no page per fund.
FINRA publishes, twice a month, the number of shares sold short in each company. Their share of the stock is computed here on the count the company reports to the SEC, and this market appears in no ranking shared with the others.
The CNB no longer publishes a file: the positions are read from its public page.
The MNB no longer publishes a file: the positions are read from its public page.
The Central Bank of Iceland no longer publishes a file: the positions are read from its public page.
The CMVM no longer publishes a file: the positions are read from its public page.
Register changes
A regulator publishes its rules, but never the day a column disappears from its file. Every line of the register journal was checked here, on the date shown. When only the year is known, the line gives only the year.
| Market | Date | Change | Reference |
|---|---|---|---|
| Czechia | August 8, 2026 | Checked that day: the current register returns no row, while its history answers and reaches back to the last position. Empty is not unreadable, and that second call is the proof. | none |
| Greece | August 5, 2026 | Measured that day: the regulator accepts no secure connection, on either of its two hostnames. This market is read in the clear because it offers nothing else. | none |
| United States | July 15, 2026 | Measured that day: of the 22 375 securities published, 3 983 carry the same sentinel value in the column that looks like a comparable ratio. It is not one, and it is not read. | none |
| United Kingdom | July 13, 2026 | From that date the funds are no longer named: the register publishes one total per company. The file that named them has not moved since, and it is kept here as history. | PS26/5 |
| Czechia | 2022 | No open position since that date. The register answers and holds nothing: that is a state, not a failure. | none |
| Hungary | February 2018 | No open position since that date. The register answers and holds nothing: that is a state, not a failure. | none |
