1. Report Industry Investment Rating No relevant content provided. 2. Core Views of the Report - In September, convertible bonds underperformed underlying stocks overall, but there was significant differentiation among sectors. High - price convertible bonds continued their strong performance, and the high - price convertible bond index led the gains. The technology sector's rise slightly declined, while the financial sector was under pressure. Under the expectation of a bull market in the equity market, the double - low strategy continued to underperform the high - price and low - premium strategy [1][2][3]. - Although high - price convertible bonds have stronger equity characteristics, the double - low strategy still has the advantage of being offensive and defensive. Actively screening sectors and individual stocks according to market trends can help obtain excess returns. In the context of the continuous rise of convertible bonds, the valuation has reached a relatively high historical level, and the number of individual bonds triggering forced redemptions is increasing [3]. 3.

After active screening, 10 individual bonds were obtained, mainly concentrated in the light manufacturing and non - ferrous metals industries. From September 1st to 30th, the portfolio's return rate was 5.92%, outperforming the CSI Convertible Bond Index by about 4 pct. Cumulatively, since its construction in June, the portfolio's cumulative return rate was 19.12%, outperforming the CSI Convertible Bond Index by 5.3 pct [31]. - October double - low portfolio recommendation: In the context of the continuous rise of convertible bonds, individual bonds with low double - low values face higher risks of delisting and forced redemption, and the number of eligible individual bonds has decreased. This month, 10 individual bonds were selected from the bottom 10% of double - low value rankings. These recommended individual bonds are mainly concentrated in non - ferrous metals, basic chemicals, and power equipment industries, with an average convertible bond price of 133 yuan, conversion value of 122 yuan, and conversion premium rate of 9% [35]. 3.2.2 Allocation Recommendation: Focus on Technology Growth and "Anti - involution" - Related Sectors - Convertible bonds have entered a high - valuation range. At this stage, more attention should be paid to the safety margin. Under the unbroken expectation of a bull market, sectors at a low level with the expectation of a catch - up can be focused on. It is recommended to pay attention to "anti - involution" - related sectors with long - term logic, such as photovoltaic, lithium battery, engineering machinery, and chemical industries, as well as the callback layout opportunities of high - growth sectors such as robotics, semiconductors, AI computing power, and innovative drugs [37].
