International companies trading in New York ended lower Thursday as weak economic data from Europe and Asia pointed toward softening in global economies.

The Bank of New York index fell 0.7% to 128.67. Lackluster global manufacturing and labor data underlined worries about economic growth, with data showing business activity in the euro zone contracted at the fastest pace since June 2009. Meanwhile, a survey showed Chinese manufacturing output fell to a 10-month low.

The Asian index fell 1.1% to 122.31.

A federal judge ordered Taiwan-based AU Optronics Corp. (AUO, 2409.TW) to pay $500 million for participating in a conspiracy to fix prices on liquid-crystal-display panels.

The penalties are among the stiffest on record for antitrust cases. Shares dropped 2.8% to $3.76.

German car maker Daimler AG (DDAIY, DAI.XE) lowered its full-year earnings outlook for its core Mercedes-Benz division, an indication that demand for luxury cars is slowing amid a softening global economy.

NordLB downgraded Daimler on the cut outlook, lowering its rating on the stock to hold from buy and reducing its price target to EUR40 from EUR51. The firm said Daimler's 2013 targets could now also be called into question. Shares dropped 3.1% to $50.57.

Shares of Peru-based Compania de Minas Buenaventura SA (BVN, BUENAVC1.VL) fell 1.3% to $39.55 as the president of Peru's northern Cajamarca region, Gregorio Santos, said he believes the Minas Conga copper and gold project remains unfeasible. The miner holds a 43.65% stake in Minas Conga, while Newmont Mining Corp. (NEM) holds a majority 51.35% stake and the World Bank's International Finance Corp. holds the rest. Minas Conga has faced opposition from local politicians and residents over concerns it would harm the local water supply, which the company and the Peruvian government deny.

After postponing a Sept. 13 shareholders' meeting on approving a disputed capital increase, Chile's energy holding company Enersis SA (ENI, ENERSIS.SN) plans to have the meeting in mid-December, Enersis's controlling shareholder, Spain's Endesa SA (ELEZY, ELE.MC), said in a filing with the Spanish regulator Thursday. Enersis's plan to conduct a $8.02 billion capital increase triggered some minority shareholders' opposition as they didn't agree with the deal's conditions. Shares of Enersis ended the day down 1.1% at $16.45.
