By Carla Mozee Brazilian and Mexican stocks moved higher Friday afternoon, aided by advances among resource-related issues in part as a pullback in the U.S. dollar supported a climb in prices for most commodities. Brazil's Bovespa recently rose 0.9% to 64,524, helped by gains among communications, housing, and utility stocks, with electricity provider CPFL Energia (CPL) up 1.3%. Market heavyweight Petrobras' (PBR) preferred shares moved 1.6% higher, their first advance in seven sessions. Friday's gains for Petrobras were supported in part by a nearly 3% jump in oil prices as traders looked to a potential storm forming in the Caribbean. Mexico's IPC index rose 0.8% to 0.8% to 32,570, led by construction group Empresas ICA (ICA) and industrial conglomerate Alfa as their shares each rose more than 3%. The index was on track to fall about 0.7% for the week. Metals stocks in Mexico City were all higher Friday, with copper miner Grupo Mexico up 1.5% and Compania Minera Autlan, which provides manganese ore for use in the steel industry, up 0.9%. Silver mining company Industrias Penoles, gained 1.3%. July silver futures rose 37 cents to $19.11 an ounce and July copper rose 9 cents to $3.09 a pound. Prices for oil and metals found room to rise as the dollar eased from gains the euro ahead of meetings of the Group of 20 and Group of 8 leading industrialized countries in Toronto. Officials are likely to work on efforts to boost global economic growth. Brazil and Mexico, the largest- and second-largest economies in Latin America, are members of the G-20, as is Argentina. The dollar index (DXY), which gauges the dollar's move against a basket of six other currencies, fell 0.5%. Mexican and Brazilian stocks had traded lower earlier in the session as investors mulled mixed economic data from the U.S. Mexico's economy is particularly sensitive to conditions in the U.S. because the U.S. is Mexico's biggest trading partner. Earlier Friday, the U.S. Commerce Department revised its reading on first-quarter growth economic activity to a rate of 2.7%, down from its original estimate of 3.2%. The revision hadn't been expected by economists surveyed by MarketWatch. At the same time, a reading of consumer sentiment rose to a 2-year high in June, according to a survey by Reuters and the University of Michigan. The UMich index rose to 76.0 in late June, up from 73.6 in May and 75.5 in mid-June. June's reading was the highest reading since January 2008, the month after the recession began. In Sao Paulo, the index was on track to post a modest gain for the week. The Bovespa suffered its worst loss this week on Thursday, shedding 1.9% after an unexpected rise in the country's monthly jobless rate to 7.5%. The index has also been under pressure as investors continued to react to oil giant Petrobras' decision this week to delay a long-awaited sale of shares, and estimates of the value of the sale have run as high as $60 billion. In market moves, Brasil Telecom (BTM) shares rose 1.4% and wireless services provider Vivo Participacoes (VIV) gained 0.4%. Brazil's telecom agency said Thursday Vivo remained the cell-market leader with a 30.25% share of subscriptions. Total cell subscriptions increased 1.6% in May. Steelmakers Usiminas and CSN (SID) rose 1.2% and 0.5%, respectively, and iron ore provider Vale (RIO) gained 1%. Chile's IPSA rose 1.2% to 2,313. The peso advanced against the dollar, aided by a rise in copper prices. Chile is the world's largest copper producer. The IPSA index was in line for a scant gain for the week. Trading in Santiago will be closed Monday for a holiday. Argentina's Merval rise 0.6% on Friday to 2,314, and was on track for a weekly loss.
