Brazil

Klabin Segall SA (KSSA3 BS): The real estate developer that said its contracted sales almost doubled in the third quarter maintained its ``hold'' rating from Banco Fator Corretora analyst Eduardo Silveira. The company's concentration of low-income developments ``could pose a risk to the company'' should Brazil's economy slow, Silveira wrote. Klabin Segall is also among the most highly leveraged builders in the country, he wrote in an Oct. 17 note. Klabin Segall rose 5.4 percent to 2.95 reais.

Marisa SA (MARI3 BS): Banco Itau Holding Financeira SA, Brazil's second-biggest non-government bank, formed a partnership with Marisa to offer credit cards to the clients of the clothing retailer. Marisa rose 6.5 percent to 3.3 reais.

Petroleo Brasileiro SA (PETR4 BS): Brazil's state-controlled oil company delayed the planned release of a 2009-2013 investment plan until December as an international credit crunch made it harder to assess the cost of capital, Petrobras said Oct. 17. The plan, scheduled to have been released this month, was to have increased investment to help develop Tupi and new fields being found near it off Brazil's coast, according to Chief Financial Officer Almir Barbassa. Petrobras rose 3.6 percent to 22.99 reais.

Redecard SA (RDCD3 BS): Goldman Sachs Group Inc. cut its rating on Redecard, the Brazilian credit- and debit-card processing company, to ``neutral'' from ``buy,'' citing its ``significant'' outperformance compared with other Brazilian financial stocks. Redecard fell 4 percent to 23.75 reais.

Tam SA (TAMM4 BS): Brazil's largest airline by passengers carried was upgraded by analysts at Credit Suisse Group, who said the company's share of the business-travel market is helping to keep its fares high, boosting revenue. Tam's rating was raised to ``outperform'' from ``neutral'' by Credit Suisse's Luiz Otavio Campos. Tam fell 5 percent to 25.65 reais.

Uniao de Bancos Brasileiros SA (UBBR11 BS): Brazil's third- biggest non-state bank was raised to ``buy'' from ``neutral'' at Goldman Sachs Group Inc., which said a recent share-price decline was ``overdone.'' Unibanco fell 3 percent to 13.39 reais.

Chile

Empresa Nacional de Electricidad SA (ENDESA CC): Wholesale electricity prices in Chile will rise 13 percent in the most populated areas next month as a strengthening U.S. dollar boosts the cost of fuel for power producers. The increase will add 5.6 percent to residential power bills in central Chile, the state- run National Energy Commission said Oct. 17. Endesa, the country's biggest generator, rose 2.2 percent to 756.2 pesos.

Lan Airlines SA (LAN CC): Chile's biggest air carrier probably will report ``pretty favorable'' third-quarter earnings, Patricio Hernandez, an analyst at Banchile Inversiones, said in an Oct. 17 interview. He advises clients to buy the stock, estimating it will rise to 7,400 pesos as lower fuel costs help offset any slowdown in traffic. Lan gained 3.8 percent to 5,399.20 pesos.

Mexico

Controladora Comercial Mexicana SAB (COMERUBC MM): The owner of supermarkets and Costco stores in Mexico was profitable until the start of this month, the executive in charge of its bankruptcy restructuring, Jose Calvillo, said in an interview Oct. 17. The decline of the peso left it with $1 billion in currency derivative liabilities and unable to refinance debt. Comercial Mexicana fell 3 percent to 3.63 pesos.

Grupo Modelo SAB (GMODELOC MM): Mexico's largest brewer may say third-quarter earnings before interest, taxes, depreciation and amortization fell 4.4 percent from a year earlier, Citigroup Inc.'s Banamex unit said in a research report Oct. 17. The company's Ebitda may fall because of bad weather, high food inflation and fewer remittances to Mexico from U.S. workers, analysts wrote. Modelo is scheduled to report results this week, according to Bloomberg data. Modelo rose 4 percent to 40.92 pesos.
