Key legal question
Whether the bank breached Art. 398(2) CO by recommending an unsuitable investment strategy without a client profile.
Extracted holding
No breach was established. Where the contractual risk profile was clear and the clients knowingly accepted a risky strategy, the absence of a client profile did not help the claimant.
Extracted reasoning
A client profile serves to clarify risk tolerance only when the contractual arrangements are ambiguous. Relying on a hypothetical conservative profile after knowingly accepting a risky strategy is contradictory and abusive under Art. 2(2) CC.
