Hong Kong stocks slipped on Monday with some investors locking in gains from the market's recent rally while others preferred to stay on the sidelines ahead of the one-day local Mid-Autumn Festival holiday on Tuesday.

The benchmark Hang Seng Index ended the day down 183 points, or 0.67 percent, at 26,957, its second consecutive trading day of declines.

Shares in the Hang Seng Automobile Index led the decline, slipping 1.13 percent, with Li Auto falling 3.3 percent, Xpeng easing 1.8 percent and Leapmotor declining 0.6 percent.

Shares of key tech players fell 1.1 percent.

Hong Kong-listed gold miners rose after the precious metal climbed to a record high with Shandong Gold Mining's shares up as much as 7.2 percent to HK$40.40, their highest level since their debut in September 2018. They ended the day 5.3 percent higher.

Stock of Zijin Gold, which debuted on September 30, soared up to 9.5 percent to a fresh high of HK$148.90 and ended 8.2 percent higher; Zhaojin Mining rose 3.8 percent and Zijin Mining climbed 2.5 percent.

Gold surged past the US$3,900-an-ounce level, driven by safe-haven demand following a fall in the yen and a U.S. government shutdown, among others.

Copper prices rose on Monday to the highest level in more than 16 months, due to concerns about supply from top producer Chile and major supplier Indonesia, sending MMG and Jiangxi Copper up 0.3 percent and 1.2 percent respectively.
