China's No1 portal Sina announced yesterday a record third-quarter profit thanks to healthy advertising sales and increasing demand for mobile-related services. The Shanghai-based firm saw its profit for the three-month period rise to US$11.65 million, compared with a $7.12 million gain in the previous quarter and a $559,000 loss a year ago. This represents a diluted earnings per share of 21 cents, beating its July forecast of between 16 cents and 18 cents. Non-advertising revenue - mainly from short messaging services (SMS) - climbed almost 25 per cent to US$20.47 million from the second quarter. 'The overall market for SMS products in China is going to grow about 60 per cent next year,' said chief executive Wang Yan. 'We believe we can grow with the market.' As of the end of last month, Sina said it had recorded an accumulated unrealised loss of US$4.7 million from its investment in Hong Kong-listed Sun Media Group. Shares of Sina gained 3.4 per cent to $43.42 on the Nasdaq in New York yesterday before the results announcement.
