Being a swiss attorney-at-law working in the banking/it sector: in Switzerland, you don‘t need those disclaimers. Even if sbdy from a different jurisdiction may read it and then believes he has a claim against you.
Companies in the finance sector have usually regulatory requirements to publish a website with certain data/information (for example: best execution under MiFid II). But this has nothing to do with you becoming potentially liable to somebody following your investment advice, as long as you don‘t have an investment advisory mandate with them.
Two things that may help you to sleep better at night:
- Financial loss is not pe se claimable. The loss must fulfill the critieria of a liability provision of swiss law to become claimable.
- Claims for damages based on Art. 41 Code of Obligation (tort; extracontractual damage) are very, very hard to win in court.
What dom.swiss refers to are cross-border rules. You don‘t need to worry about those if you are an individual, i.e. non-regulated entity.
