High stakes clash for nutrition company Herbalife

Herbalife shares rose yesterday after billionaire Carl Icahn bought more than 2.3m shares in the nutrition company.

Herbalife is also the high-profile target of fellow billionaire activist investor Bill Ackman.

The stock advanced up to 3.5% after falling last week when Mr Ackman said Mr Icahn was looking to sell his stake, not increase it.
