1. Report Industry Investment Rating No relevant content provided. 2. Core View of the Report - As the issuance of the second batch of Sci - tech Bond ETFs progresses, Sci - tech Bonds have certain investment value at the current stage. The inflow of incremental funds is expected to compress the spreads of Sci - tech Bond ETF component bonds, and investors can look for opportunities in the potential spread compression of component bonds [3][27]. 3. Summary by Directory 3.1 Second Batch of Sci - tech Bond ETFs Issued, Incremental Funds to Enter the Market - On September 12, 2025, 14 Sci - tech Bond ETFs of the second batch were issued. Among them, 10 track the CSI AAA Sci - tech Corporate Bond Index, 3 track the SSE AAA Sci - tech Corporate Bond Index, and 1 tracks the SZSE AAA Sci - tech Corporate Bond Index. They were declared on August 20, approved on September 8, and officially issued on September 12 [1][7]. - Referring to the first batch, the second - batch Sci - tech Bond ETFs are expected to be listed from late September to early October. The first batch took about a month from application to listing, and the second - batch issuance is from September 12 - 18 [8]. - It is estimated that the second - batch Sci - tech Bond ETFs will raise 37 - 42 billion yuan, bringing incremental funds to the Sci - tech Bond market. The first batch of 10 ETFs had a cap of 3 billion yuan each and raised 28.99 billion yuan in total, reaching 96.6% of the cap [1][12]. 3.2 Characteristics of Underlying Assets and Market Effects of the First Batch of Sci - tech Bond ETFs - As of September 11, the first - batch Sci - tech Bond ETFs held 633 Sci - tech Bonds, with remaining maturities mostly 2 - 3 years and 4 - 5 years, implied ratings mostly AAA and AA +, and industries mostly in the industrial sector [2][14]. - The passive allocation effect of the first - batch Sci - tech Bond ETFs significantly affected the valuation of component bonds. The excess spreads of component bonds (calculated as the spread of Sci - tech Bond ETF component bonds minus the spread of medium - and short - term notes of the same maturity and rating) narrowed significantly during the issuance and construction periods. The process can be divided into three stages: from issuance to listing, the excess spread compressed by 5.1BP to - 7.9BP; after listing, it continued to decline by nearly 5BP to - 12.7BP; although there was a slight correction in credit bonds, the expected new issuance of Sci - tech Bond ETFs drove the excess spread to repair to - 12.6BP [2][21]. 3.3 Seize Opportunities in Spread Compression with Incremental Funds - The second - batch Sci - tech Bond ETFs are expected to bring 37 - 42 billion yuan of incremental funds. Similar to the first batch, the excess spreads of their component bonds are expected to compress again during the concentrated construction and allocation period after September 12 [3][27]. - The yields of existing ETF component bonds are generally 4 - 20BP lower than non - component bonds in the index, showing an obvious premium. Attention should be paid to the degree of gambling [3][28]. - There are still over 363 index component bonds not fully covered by the first - batch ETFs. Investors can select high - quality individual bonds that meet the requirements of new ETF construction to capture spread compression opportunities [4][28].
