Raven Russia Preference shares are yielding around 9% at the current price. They are held in large numbers by the directors, Invesco and Neil Woodford. They do not appear on the list of Preference Shares on this site. The shares are liquid and the company has a large land bank as well as its established warehouses in major Russian cities. I am tempted to buy as the yield possibly reflects the risk but would value any comments from those with more experience.
