Own and like CEY.
As to the general strength in the coal sector, there are other positive background factors (aside from the whole takeover saga over at MCC) - general world economic recovery firing up buyer demand; and talk is starting up again about the long term commodities bull market; and the Reserve keeps saying that a partial rationale for increasing domestic interest rates is the expected ongoing strength in commodities prices and demand.
It's just a sweet spot for the industry atm. Higher interest rates are driving the $AUD upward, notionally denting exporters earnings, but that's the beauty of CEY, it has strong domestic markets as already described by other posters.
