What is AMPER, S.A.'s short interest?
0.71% of share capital as of 12 Oct 2026. "Short interest" is the US term; the CNMV 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.
