Brazilian Stock Movers: MMX, Gafisa, Petrobras, Usiminas, Vale

Sept. 9 (Bloomberg) -- The following companies had unusual price changes in Sao Paulo trading. Stock symbols are in parentheses and prices are as of 4:15 p.m. New York time. Preferred shares are usually the most-traded class of stock.

The Bovespa Index fell 3.2 percent to 55,778.39.

MRV Engenharia & Participacoes SA (MRVE3 BS) slumped 7 percent to 12.89 reais, and Gafisa SA (GFSA3 BS) tumbled 6.9 percent to 7.32 reais. Homebuilders led declines by companies that depend on domestic demand after central bank President Alexandre Tombini said in an interview with Globo News Television that the bank will cut its forecast for economic growth this year.

Petroleo Brasileiro SA (PETR4 BS) slid 2.5 percent to 20.15 reais. Brazil’s state-controlled oil company followed crude prices lower. Oil fell the most in a week in New York as the euro tumbled against the dollar on concern that Greece’s deteriorating debt crisis will lead to a default.

Miners Vale SA (VALE5 BS) and MMX Mineracao & Metalicos SA (MMXM3 BS) fell, with Vale retreating 1.2 percent to 40.93 reais and MMX dropping 4.7 percent to 7.77 reais, as metal prices declined. Copper fell amid concern slowing economies may damp demand for industrial metals.

Voting shares of Usinas Siderurgicas de Minas Gerais SA (USIM3 BS) rose 1.3 percent to 23.95 reais. Gerdau SA may seek to counter Cia. Siderurgica Nacional SA’s offer to buy a 26 percent stake in the company from Camargo Correa SA and Votorantim Participacoes SA, O Estado de S. Paulo reported, without saying where it got the information.
