Hong Kong's three major indices closed in positive territory on Monday.

The benchmark Hang Seng Index advanced 0.33% to finish at 23,412.18 points.

The Hang Seng Tech Index posted a stronger gain of 1.81%, while the Hang Seng China Enterprises Index edged up 0.07%.

Tech Sector Performance

Technology and internet stocks were mostly higher during the session.

Shares of Tecent Holdings Ltd (HKG: 0700) rose more than 3%, while Meituan (HKG: 3690) shares declined over 2%.

Semiconductor Strength

Semiconductor shares showed notable strength.

Hua Hong Semiconductor Ltd (HKG: 1347) surged more than 15%, reaching a new all-time high.

This move followed analysis noting that Taiwan Semiconductor Manufacturing Company (TSMC) has begun notifying customers of price increases for its wafer fabrication services.

The hikes, reported to be between 5% and 10%, are expected to affect all advanced processes at 7nm and below, including the 3nm node, impacting approximately 75% of its wafer revenue.

Battery and Pharmaceutical Moves

The lithium battery sector also gained ground, with Longpan Technology Co., Ltd. (HKG: 603906) climbing over 3%.

Research from Huatai Securities indicated that global demand for lithium batteries continues to grow, with Europe's new energy vehicle penetration rate potentially exceeding 30% this year.

Combined with increasing battery capacity per vehicle, the supply-demand dynamic in the industry chain is gradually tightening.

In the first half of the year, capacity utilization rates for lithium battery material companies have risen, product prices have recovered, and industry profitability is entering a repair phase, with both volume and price trending upward.

Contract research organization (CRO) and innovative drug concept stocks rallied collectively.

Asymchem Laboratories (Tianjin) Co., Ltd. (HKG: 6821) jumped more than 13%.

The sector's strength coincided with the BIO2026 International Convention, a major global biotechnology event held in San Diego, USA, from June 22 to 25.

The conference is reported to cover cutting-edge fields such as artificial intelligence, digital health, and cell and gene therapy, where the high-efficiency advantages of Chinese CXO enterprises have drawn significant attention.
