Frequently asked questions

How shorted is ATON right now?
Disclosed net short positions total 0.73% of ATON's share capital as of 12 Oct 2026, per the AMF's public register. That makes it the 60th most shorted French stock, out of 86 companies with disclosed positions.
Who is shorting ATON?
The AMF names each holder of a position of 0.5% or more. Currently disclosed: CITADEL SECURITIES (EUROPE) LIMITED.
What is ATON's short interest?
0.73% of share capital as of 12 Oct 2026. "Short interest" is the US term; the AMF 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 AMF's register every trading day.
