BEIJING, Nov. 19 (Xinhua) -- Chinese shares staged a broad-based rebound on Wednesday, making up the previous day's losses after an overnight rally on Wall Street.

The benchmark Shanghai Composite Index finished at 2,017 points, a gain of 6.05 percent. The Shenzhen Component Index rose 6.14 percent to 6,679 points.
