Question juridique clé
Whether the cantonal court arbitrarily found that the client knew or should have known the options price was falling from 26 January 2000 onward.
Solution extraite
The finding was not arbitrary; it was supported by concrete indications, including the client’s market knowledge, online monitoring, speculative short-term strategy, and repeated bank requests to sell.
Motifs extraits
The Federal Court held that the complaint largely attacked the evidentiary weight given to the facts. Given the client’s sophistication and the time lapse, the inference that she knew or should have known of the decline was not insupportable.
