Two-thirds of China's Qualified Domestic Institutional Investors (QDII) funds saw stronger revenues in the first two months of this year, helped by the better performances of developed economies, the Shanghai Securities News reported on Wednesday.

Out of the 99 QDII funds approved by China's regulators to invest overseas, 66 realized a positive return at the end of February.

Those funds mainly focusing on developed markets posted stronger gains than their peers in emerging markets, partly because most emerging economies have been facing problems such as economic restructuring, capital outflow and currency depreciation.

Analyzed by sector, QDII funds linked with real estate and gold investment led the gains, with Penghua Global Discovery (QDII-FOF) registering an increase of 9.78 percent in net asset value, followed by Lion Fund (QDII-FOF) and Harvest Fund (QDII-FOF-LOF) with an increase of 9.7 percent and 9.48 percent respectively.

Sinolink Securities said in its latest investment note that investors should scale down their exposure in emerging markets while turning more to funds focusing on sectors such as healthcare, consumer goods and the Nasdaq 100 index in mature markets.

The average rate of return for China's QDII funds reached 4.86 percent in 2013, with GF Fund (QDII) ranking as the most profitable fund by registering an increase of 43.43 percent in net asset value.

Four gold funds including E Fund (QDII-LOF-FOF), Lion Fund (QDII-FOF), Harvest Fund (QDII-FOF-LOF), and China Universal Asset Management (QDII-FOF-LOF) suffered an average loss of 30 percent as gold prices fell sharply last year.
