Zhihu (ZH) shares surged 6.76% in pre-market trading on Monday, reflecting heightened investor optimism following the company's recent share repurchase activity.

The uptick comes after Zhihu repurchased 99,000 of its shares for $116,600 on January 9, a move often interpreted as a signal of management's confidence in the company's valuation and future growth. Such buybacks typically reduce share supply, boosting demand and driving prices upward.
