China stocks opened the year with a big gain Tuesday, and good sentiment might lead to a healthy first week of trading. But the market looks like it’s one bad news story away from a significant drop.

Buoyed by a rise in China’s PMI announced Sunday, Hong Kong’s Hang Seng Index opened 2012 by rising 2.4% to 18,877, and the index of Chinese companies jumped 3.0% to 10,235.

In addition to the good PMI numbers, recent promising economic data from the U.S. should allow the Hang Seng to trade in a higher range of 18,400 to 19,000 this week, according to Jackson Wong, vice president of equity sales at Tanrich Securities.

“Large caps are the best performers with oil and petrochemical companies like PetroChina (PTR), Sinopec (SHI), and CNOOC (CEO) all posting decent gains,” he told Equities in an email.

But Wong said the market basically lacks direction is still news driven. “I don’t recommend people chasing in at this point…,” he said.

For the year, Wong predicts the Hang Seng will reach 20,600 by mid-2012 and could go to 23,800 by the end of the year if additional economic easing measures are implemented by China, the U.S. and Europe. End
