Steel maker AK Steel Holding Corporation caught a big upgrade from analysts at Deutsche Bank. The analyst boosted its rating on AKS to 'Buy' from a previous 'Hold', citing recent share price weakness and valuation.

Deutsche said that "It now has a more positive outlook for AK Steel's specialty businesses, and as always, we view it as an attractive acquisition candidate. Key risks are input operating costs, excess global capacity, international steel prices, global growth and FX rates."
