Genuinely curious about how it works in Sweden, so I have a question.

Imagine a swedish person overhearing a conversation at a restaurant (in Sweden) between two people (insiders to a particular public company that is also located in Sweden) sitting at a different table. That conversation contained non-public material information about the company those two people work for. The swedish person who overheard the insider conversation makes a successful trade that makes them profit (using that information).

Would this count as insider trading in Sweden? Afaik (which I could be mistaken about), it wouldn't in the US.
