The short interest that never appears in the register

Name: Swedish short interest gap — aggregate versus named register
Creator: d-nvest
Published: 2026-09-09

Finansinspektionen publishes two things about the same issuer: an aggregate net short position that includes holders below the naming threshold, and the register of named disclosures. The difference is short interest that is disclosed to the regulator and invisible in the public register.

Dated on the register state we observed, not on a publication date: this regulator publishes no date of its own. The date is therefore ours, and it is always at or after the moment the file became public — a backtest built on it is conservative, never early. State observed on 2026-09-08

What this page does not show, and why

A gap is only meaningful if both sides are proven. When an issuer's named disclosures cannot be attached to it, the sum of the public side is zero and the gap equals the whole aggregate — which reads as “100% of this issuer's short interest is hidden below the threshold”. That sentence would be false, large and plausible, so those issuers are counted here and left out of the table.

337

issuers in the aggregate register

235

issuers with a gap that is proven on both sides

known to the identity bridge, but no named disclosure could be attached — not shown

issuer identifier unknown to the instrument bridge — not shown

Every gap below is an UPPER bound, and the table says so on each row: nominative disclosures whose instrument is unknown to the bridge cannot be counted on the public side, so that side is a lower bound. 6120 such disclosures exist in this regime today.

Coverage

Why this exists for one country

The gap needs a regulator that publishes an aggregate INCLUDING positions below the naming threshold. Most publish the named register only — there is then nothing to compare it against. Below, every jurisdiction whose register we ingest, and what it publishes.

Jurisdiction	Regulator	Aggregate view
SE	Finansinspektionen	published — republished here
GB	FCA	published, but its licence forbids redistribution FCA — Legal terms (conditions 3.2 à 3.5) interdit la redistribution — se limiter au lien et à une citation courte

IS	Seðlabanki Íslands	no aggregate view observed

SK	NBS	no aggregate view observed

“No aggregate view observed” is not “none exists”: we have not called every European regulator on this question, and claiming otherwise would be unverifiable. The day a source appears, it shows up here on its own.

The gap, issuer by issuer

Declared to the regulator, absent from the register

Sorted by the widest gap. The two ratios are never summed: they count different populations under different thresholds, and adding them would double-count the holders that appear in both.

The preview stops here. 215 more issuers carry a proven gap today.

The underlying registers are public and free at the regulator — the link is in the licence note below. What is behind the wall is our computation, not the regulator's data.
