CVR Partners, L.P. (NYSE: UAN ) slid 16%. A master limited partnership (MLP) focused on nitrogen fertilizer, it yields a hefty 10.5%. The company's recent performance was whacked by a plant shutdown for repairs, but production there has resumed. (The company has just that one plant, so the shutdown was quite a big deal.) Its recent quarter was solid, with record production of urea ammonium nitrate (UAN) and a rosy outlook, as CVR's UAN facility has been expanded. Bulls like both its growth prospects and its massive yield.
