Frequently asked questions

How shorted is RaySearch Laboratories AB (publ) right now?
Disclosed net short positions total 5.52% of RaySearch Laboratories AB (publ)'s share capital as of 12 Oct 2026, per the Finansinspektionen's public register. That makes it the 6th most shorted Swedish stock, out of 101 companies with disclosed positions.
Who is shorting RaySearch Laboratories AB (publ)?
The Finansinspektionen names each holder of a position of 0.5% or more. Currently disclosed: Marshall Wace LLP, JPMorgan Asset Management (UK) Ltd, GSA Capital Partners LLP and 3 more.
What is RaySearch Laboratories AB (publ)'s short interest?
5.52% of share capital as of 12 Oct 2026. "Short interest" is the US term; the Finansinspektionen publishes each disclosed net short position of 0.5% or more by name, summed here, so it is a lower bound on all short selling in the stock.
What does this number include?
The sum of individually disclosed net short positions of 0.5% or more of share capital. Positions between 0.1% and 0.5% are reported to the regulator privately and are not public, so the true total can be higher.
How often is this updated?
Position holders must disclose changes by the next trading day; we refresh from the Finansinspektionen's register every trading day.
