China stocks continued their decline this week with a substantial drop Tuesday under the weight of concern over a weak Chinese economy.

Hong Kong’s Hang Seng Index fell 1.1% to 20,088. It has declined 2.0% already this week. The index of Chinese companies slumped 1.5% to 10,871. With many investors on the sidelines, turnover was light.

“The Hang Seng has dropped through the 21,000 support level and the next resistance is the 250-day moving average, 20,600,” according to Dickie Wong, executive director of research at Kingston Securities.

The fall is partly due to a worry China would continue tightening policies even as property prices fall, he said.

He added that a closer look at recent Chinese economic data is discouraging. For example, weakness in the key export sector indicates a slowing economy.

And although most blue chips are reporting results in line with predictions, there are some weak points. Ping An Insurance (PNGAY) is testing a key support level in the wake a recent profit warning from China Life (LFC), Wong told Equities.

One sign of weakness of the market is a drop in the Hong Kong dollar due to a slowing of the inflow of foreign funds, he said.

But some sectors will outperform the market, according to Wong, including consumer-oriented stocks. Producers and retailers for luxury goods such as Prada (PRDSY) will do well, he said. End
