Frequently asked questions

How shorted is F-SECURE OYJ right now?
Disclosed net short positions total 0.51% of F-SECURE OYJ's share capital as of 12 Oct 2026, per the FIN-FSA's public register. That makes it the 17th most shorted Finnish stock, out of 18 companies with disclosed positions.
Who is shorting F-SECURE OYJ?
The FIN-FSA names each holder of a position of 0.5% or more. Currently disclosed: QVT FAMILY OFFICE FUND LP.
What is F-SECURE OYJ's short interest?
0.51% of share capital as of 12 Oct 2026. "Short interest" is the US term; the FIN-FSA 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 FIN-FSA's register every trading day.
