Core Viewpoint - The article emphasizes the recent revisions to the National Index for Commercial Satellite Communication, focusing on a more concentrated approach to the index's composition and weight distribution, enhancing its representation of the upstream satellite manufacturing and launch sectors [4][6][10]. Group 1: Index Revisions - The index has clarified its focus on "commercial satellite communication," limiting sample companies to those involved in satellite manufacturing, launching, operation, and ground equipment, while excluding peripheral companies [6]. - A significant change in the weight setting rules has been implemented, mandating that the combined weight of satellite manufacturing and launching companies must be no less than 50%, while individual weights of other sectors cannot exceed 3% [7]. Group 2: Market Impact - Several communication stocks, including China Telecom, have been removed from the index, while companies like GuoBo Electronics and Si Rui New Materials have been added, reflecting a shift towards core upstream sectors [8][10]. - The satellite ETF (159206.SZ) has seen its scale grow from 1.6 billion to over 3 billion, indicating strong investor interest and inflow into the satellite sector [11][14]. Group 3: Investment Trends - Since early September, the satellite sector has attracted significant capital due to supportive policies, rocket launches, and substantial growth potential, leading to increased attention from investors [13]. - The satellite ETF has experienced a 71% increase in shares this month, highlighting a trend where funds are increasingly favoring the satellite communication index over broader satellite industry indices [14][20]. Group 4: Comparative Performance - The satellite communication index focuses on satellite internet construction and communication, while the satellite industry index encompasses a broader range of satellite-related activities, including navigation and remote sensing [18]. - Historical performance shows that while the satellite industry index performed better in previous years, the satellite communication index has shown superior performance in recent times, with both indices yielding similar returns this year [19][20].
