Swiss banking group Syz & Co has launched a fund that combines novel strategies aimed at producing positive returns in both normal markets and during sudden sell-offs.

The Oyster Multi-Manager Tail and Trading fund has an 80% allocation to commodity trading advisers, or CTAs, with the remaining 20% allocated to a tail-risk hedging strategy. A CTA fund offers managed futures accounts to investors. It typically has low correlation with financial markets and positive yield expectancy, but can be volatile.
