广发恒生A股电网设备 ETF投资价值分析：聚焦新型电力核心资产，布局“十五五”电网高景气周期

• The report primarily focuses on the investment value of the "恒生A股电网设备指数" (HSCAUPG.HI), which is a thematic index designed to reflect the performance of China's A-share listed companies in the power grid equipment sector. The index was launched on February 28, 2022, and its methodology includes selecting companies with at least 40% of their revenue derived from energy infrastructure, power equipment, industrial components, and intelligent technologies. The index is weighted by free-float market capitalization, with a cap of 10% per constituent stock[37][38][39] - The index underwent a significant revision in 2025, reducing the number of constituent stocks from 100 to 50, focusing more on downstream power grid equipment manufacturing. This adjustment enhanced the index's purity and representation of the modernization and specialization of China's power grid equipment sector[37][38][39] - The index's sectoral distribution is highly concentrated, with approximately 70% allocated to power grid equipment, 13% to communication equipment, and smaller proportions to automotive components, metal materials, wind power equipment, and other industries. This structure ensures a strong focus on the modernization of power grid infrastructure, automation, and digitalization[39][41][42] - The index's internal structure is dominated by high-tech and high-certainty segments, such as transmission and transformation equipment (31% weight) and power grid automation equipment (21% weight). These segments benefit from China's "十五五" strategic planning, which emphasizes the construction of ultra-high voltage backbone networks, upgrades to main grid systems, and the integration of renewable energy bases[39][41][43] - The index has demonstrated strong performance, with a cumulative return of 335.48% since its base date, significantly outperforming the申万电网设备行业指数 (151.41%) and the上证指数 (64.96%). It exhibits high returns, moderate volatility, and superior risk-adjusted returns, with a Sharpe ratio of 4.42 over the past year and consistently above 1.0 over longer periods[55][56][58]
