LONDON (MarketWatch) -- Goldman Sachs on Monday reshuffled its ratings on the European steel sector, saying companies that have significant exposure to high-growth and specialist markets as well as strong vertical integration should benefit from a combination of growth opportunities, better margins and lower costs. The broker upgraded ArcelorMittal NL:MT -1.31% to buy from neutral and maintained its buy rating on Kloeckner & Co. SE DE:KCO +0.99% . It also downgraded Salzgitter AG DE:SZG -3.23% and SSAB AB SE:SSABA -2.19% to sell from neutral and cut ThyssenKrupp AG DE:TKA -3.16% to neutral from buy, saying the stock is fully valued.
