Questione giuridica chiave
Whether administrative assistance could be granted despite the appellant's proportionality objection and denial of suspicious circumstances.
Decisione estratta
Yes. The foreign authority had sufficient indications of possible insider trading and was entitled to obtain the transaction details, including the appellant's identity.
Motivazione estratta
The price and volume movements before the public offer, together with rapid purchases and resales through a Swiss bank, justified a suspicion of market abuse. The Swiss authority did not have to assess the appellant's explanations or require additional suspicious elements at this stage.
