Chinese online companies listed in New York saw their stocks fall slightly in early trade on Thursday after rising a day earlier.

At midday, all three key indices retreated. The Dow Jones Industrial Average dropped 1.1 per cent, the Nasdaq fell 1.11 per cent and the S&P 500 was down 0.82 per cent. Taking cues from the broader market, China’s online marketplace 58.com declined 5.8 per cent to US$44.31. Vipshop, an online discount retailer for brands, slid 3.75 per cent to US$16.17. E-commerce giant JD.com contracted 0.87 per cent to US$25.83. Alibaba opened higher, but edged down 0.07 per cent to US$58.93 at noon.
