Penghua STAR 100 ETF surges over 2.5% as semiconductor supply chain rallies

The semiconductor supply chain rallied strongly, with the Penghua STAR 100 ETF rising 2.55%. In news, the official version of the DeepSeek-V4-Flash API entered public beta, with benchmark scores surpassing the previous flagship preview version, igniting the AI narrative. TSMC's target of producing 180,000 wafers per month on its 3-nanometer process is expected to be reached ahead of schedule by early fourth quarter, while monthly shipments of its 2-nanometer process are on track to approach 100,000 wafers as planned. Soochow Securities noted that global monthly demand for HBM wafers will surge from 29,000 in 2024 to 442,000 in 2028, a compound annual growth rate exceeding 90%, as memory process upgrades drive higher investment shares for etching, thin-film deposition, and metrology inspection equipment.
