BUENOS AIRES, Jan 14 (Reuters) - Argentine stocks closed up sharply on Monday, tracking gains on Wall Street and led by energy shares, traders said.
The MerVal index .MERV of 42 leading companies jumped 2.37 percent to 2,132.38 points.
"Wall Street's gains brought greater calm to local investors, who followed the upward trend in energy and service company shares," said Hernan Labrone, an analyst at Fenix Compania Financiera.
The Dow Jones industrial average .DJI closed up 1.36 percent at 12,778,.15 points.
Gains were led by energy group Pampa Holding (PAM.BA), which surged 6 percent to 2.48 pesos a share, and Tenaris (TENA.BA), which makes steel tubes for the energy industry and whose shares jumped 4.7 percent to 65.10 pesos.
On Argentina's broad market, volume was modest at $26.3 million, while 43 issues advanced, 13 declined and 18 were unchanged.
"Volume was cautious on the Argentine market because important U.S. inflation data to be released this week is seen leading to volatility," said Diego Zabaleta, a trader at Besfamiglie brokerage.
