A veteran portfolio manager and investment officer at GAM Investments has left the asset management firm after nearly 15 years. Arvin Soh, who has helped institutional clients invest in hedge funds for GAM Alternative Solutions in New York, departed earlier this month. Soh, who has often been quoted as a hedge fund expert by publications like Bloomberg, Reuters and the FT, noted in a social media post on Tuesday that he felt it was time to move in a different direction.
