HONG KONG — Hong Kong shares extended their losing streak Tuesday, with the main stock index falling more than 2 percent Tuesday, as Asian markets slumped.

The blue-chip Hang Seng Index shed 302.95 points, or 2.2 percent, to 13,668.05, posting its sixth straight session of declines.

Shares were hurt by heavy selling in other markets, with Tokyo's index retreating almost 5 percent after being closed for a holiday Monday. Also spooking investors were new figures showing China's exports fell last month at their fastest rate in a decade.

"The overall mood is still cautious. There is no rush to buy stocks," said Francis Lun, general manager of Fulbright Securities Ltd. in Hong Kong, who expects the index to fall to as low as 13,000 this month. "The outlook for the market is not good."

Investors sold raw materials producers as commodities prices spiraled lower

Aluminum Corp. of China, or Chalco, lost 6 percent to 3.89 Hong Kong dollars, while China Shenhua, the country's biggest coal producer, dropped 3.9 percent to HK$15.66.

Shipping firms, which transport commodities, also fell. China Cosco Holdings, the country's biggest shipping conglomerate, plunged 11.2 percent to HK$4.66.
