Ossiam Portfolio holdings
Ossiam is a Paris-based Natixis Investment Managers affiliate that builds ETFs and funds on rules-based, research-driven strategies. Its range covers index trackers, long-only funds that weight stocks differently from market-cap indexes, and long/short funds aiming to be market-neutral. Four of its ETFs, listed on several European exchanges in 2011, followed equal-weight and minimum-variance strategies, the latter meant to lower risk. Bruno Poulin, who co-founded the firm, is its chief executive.
