SHANGHAI, Dec 22 (Reuters) - China stocks closed up on Monday in volatile trade as electrical utilities rose and banks spiked, while a slump in small-cap shares limited some gains.
The CSI300 index of the largest listed companies in Shanghai and Shenzhen rose 0.3 percent, to 3,394.48 points, while the Shanghai Composite Index gained 0.7 percent, to 3,127.44 points.
