Origin Agritech ( SEED) and The9 ( NCTY) were up 8% and 6.8%, respectively. China's online game developer The9 recently acquired Vision 3D game R&D engine from Trinigy to support the development of a yet-to-be-named game product.

Tata Motors ( TTM) followed accumulating 5.7% after reporting an impressive third quarter. Breezing past the street estimates, the company's net profit almost quadrupled to $530 million, while consolidated revenue increased 22%.

Petroleo Brasileiro S.A. (Petrobras) ( PBR) topped the losers' list edging 4.7% lower, after it decided to pull out of talks regarding the purchase of a 33.34% stake in Portugal's Galp Energia, owned by Italian oil major Eni S.p.A. ( E).
