Sao Paulo Stock Exchange (Bovespa) closed the week with an accumulated rise of 4 percent, despite the market's weak performance on Friday.

On Friday, index oscillated due to the instability of the market in the United States, where investors were stimulated by the creation of jobs, but simultaneously discouraged by a fall in the U.S. consumers trust index. At the end of the day, Bovespa registered a rise of 0.16 percent.

Airline company TAM, the largest in Brazil, presented the most expressive rise of the day, 7 percent, which was a surprise as the country's air traffic system faced its biggest crisis this week.

TAM and its rival airline Gol's shares have been oscillating quite wildly since the accident that killed 154 people when a Gol plane crashed at the end of September.

Mining giant CVRD and steel company Usiminas had the worst performances of the day. Negative prospects for the metal sector brought CVRD shares down to -1.27 percent, and Usiminas down to -1.2 percent. Agency Fitch Ratings said lower prices and higher expenses to steel producers will reduce their profits in short term.

On Tuesday, the Bovespa index reached a record high of 43,157 points from 42,654 the day before, which lifted the week's average rise to 4 percent.
