港股通科技ETF（159262）投资价值分析：聚焦科技成长龙头，港股通版“恒生科技”

• The Hang Seng Stock Connect China Technology Index (HSSCITI) reflects the overall performance of mainland Chinese technology leaders listed in Hong Kong. It uses free-float market capitalization weighting, with a 10% cap on individual constituent weights, and adjusts semi-annually in June and December[37][38][39] - The index strictly selects 13 technology-related fields from 105 subcategories, excluding "pseudo-tech" companies, such as semiconductor (703010) and gaming software (702040), which represent high-tech hardware and digital content sectors. This enhances the index's technological purity and representativeness[37][38] - A fast-track inclusion mechanism was introduced in 2024, allowing companies newly listed in Hong Kong and ranked in the top 10 by market capitalization to be quickly added to the index. For example, Kuaishou (1024.HK) benefited from this mechanism. Additionally, a "buffer zone" for ranks 24-36 ensures that quality growth stocks are not excluded due to short-term market fluctuations[38][39] - The index's liquidity requirement mandates a turnover rate of 0.1% or higher for investment-type indices, ensuring active trading of constituent stocks and maintaining index vitality[38] - The HSSCITI index is distinct from other international technology indices, such as the Nasdaq 100 Technology Index (NDXTMC) and the STAR 50 Index, in terms of selection criteria, weighting methods, and risk management strategies. For instance, HSSCITI uses a simple 10% cap on individual stock weights, while NDXTMC employs a two-stage mechanism to limit individual weights to 15% and the top five issuers to 60%[39][40][43]
