SHANGHAI, Nov 17 (Reuters) - Shanghai's stock market fell on Friday, on track to post its biggest weekly loss in three months, with sentiment soured by a sharp correction in alcohol producer Kweichou Moutai, seen as a bellwether among Chinese blue chips.
The Shanghai Composite Index lost 0.6 percent, to 3,380.63 points by the lunch break, declining 1.5 percent so far this week. The CSI300 index fell 0.1 percent, to 4,099.12 points.
Shares in Kweichou Moutai, the world's most valuable liquor maker, slumped as much as 6 percent from Thursday's record closing, before recovering some losses, after the company flagged risks to investors.
In a statement, Moutai, whose shares have more than doubled this year, said it hopes investors can be rational and manage risks prudently.
