SHANGHAI, Feb 9 (Reuters) - Consumer firms lifted Chinese equities on Wednesday as investors reconsidered high valuations of growth stocks amid growing external risks, while Hong Kong's Hang Seng rose as rebounding Alibaba shares led a rally in the technology sector.

** At the midday break, the Shanghai Composite index was up 0.4% at 3,466.37.

** China's blue-chip CSI300 index was up 0.25%, with the consumer staples sector higher 1.78%, and the real estate index up 0.65%.

** WuXi AppTec fell 6.6% in Hong Kong and 4.05% in Shanghai, despite the company's attempt to downplay the impact of the measures.

** Analysts said worries about sanctions and possible U.S. rate hikes had prompted investors to rotate out of growth shares into more traditional sectors.
