Three out of the four stocks that were purchased by UBS AG in a historic move closed lower amid profit-taking yesterday.

Port operator Shanghai Port Container Co Ltd dropped 1.44 percent to 13.67 yuan (US$1.65), Baoshan Iron & Steel Co Ltd fell 1.09 percent to 5.44 yuan and Shenzhen-listed telecommunication equipment manufacturer ZTE Corp shed 1.43 percent to 19.31 yuan.

Sinotrans Air Transportation Development Co Ltd was the only stock that gained among the four yesterday, inching up 0.37 percent to 21.70 yuan.

"Profit-taking hammered down these QFII plays, which I think would still face corrections in the short term before their prices stabilize," said analyst Wei Wei of West China Securities Co Ltd.

On Thursday, the four stocks rose substantially after UBS created history by making the first purchase of local currency Class-A shares by foreign investors under the Qualified Foreign Institutional Investor scheme on Wednesday.

Local share prices also fell yesterday as the Shanghai Composite Index, which tracks both Class-A shares and hard-currency Class-B shares, dipped 0.20 percent to end at 1528.85.

Trading value rose to 7.88 billion yuan from 1.1 billion yuan on Thursday.
