Report Title - Local Boom in Convertible Bond Gold Mining (1) [2] Report Date and Analysts - Report Date: September 28, 2025 - Analysts: Luo Yunfeng (SAC No.: S1050524060001), Yang Feiran (SAC No.: S1050524070001) [3] Core Views - The core driving force of the market in this round has been the improvement of risk appetite, which is an endogenous variable of profitability. Since September, considering the decline in equity trading volume, the narrowing gap between the growth and value of equities, and the increase in the proportion of the same - direction movement of stocks and bonds, it is believed that the repair of risk appetite is basically in place. In the future, risk appetite will fluctuate within a range along with profitability, with the upper and lower limits corresponding to the levels in early January (the week of January 6) and early September (the week of September 8) respectively. On September 25, 2025, it approached the lowest level in recent years on October 12, 2024 [4]. - The recent shift of the market from "banks + micro - cap stocks" to technology has a profit foundation, that is, the overall economy is bottoming out but there are local upturns. The private - sector debt growth rate is used as a proxy variable for profitability, and its downward bottom appeared in October 2024 and has not reached a new low as of July 2025 [4]. - The long - term cycle of convertible bonds is synchronized with equities. The periodic recovery of convertible bond valuations provides signals for left - hand side position - adding and profit - taking. Therefore, short - term fluctuations may be leading and amplifying signals of equities. Recently, although convertible bond valuations have been actively adjusted, they are still at a relatively high level. After the holiday, attention should be paid to locally booming industries and performance - realizing targets [6]. 01 Risk Appetite Will Follow Profitability in Range - bound Fluctuations - The repair of risk appetite in this round may be basically in place. The highest point of risk appetite since data became available was in 2007, and the lowest point was on April 7, 2025. Excluding the impact of event - driven factors, the lowest point was in January 2025. The private - sector debt growth rate, as a proxy variable for profitability, reached its bottom in October 2024 and has not set a new low as of July 2025. The risk appetite may enter a range - bound fluctuation, and on September 25, 2025, it approached the lowest level in recent years on October 12, 2024 [8]. - The overall economic fundamentals are still in the bottom - grinding stage. In the second quarter, the real GDP grew by 5.2% year - on - year, 0.2 percentage points lower than in the first quarter. Investment has been sluggish due to the real estate sector, and infrastructure investment has declined at an accelerating pace since mid - year. Consumption has been affected by the high - then - low national subsidies at the beginning of the year, and the CPI has been in a slump. Industrial product prices have shown a trend of price increases with volume contraction. From the perspective of Wind All - A earnings data, the overall economic fundamentals are still bottoming out [11][14]. 02 Fundamental Local Boom Corresponds to the Double - Innovation Market - In terms of revenue, the improvement of the Science and Technology Innovation 50 and the ChiNext Index is leading, while the Micro - cap and Dividend Indexes have the most obvious decline. In 2025Q2, the revenue growth rate of the ChiNext Index increased by 5 percentage points to 9.3%, and the Science and Technology Innovation 50 ended its relative disadvantage for three consecutive quarters. The revenue of the Micro - cap and Dividend Indexes decreased by 7.8% and 5.9% respectively in 2025Q2 [18]. - In terms of gross profit margin, compared with 2024Q2, the Science and Technology Innovation 50 and the SSE 50 had the most significant increase in gross profit margin in 2025Q2, up 2.5 and 2.0 percentage points respectively. The ChiNext Index had a gross profit margin of 24.5% in 2025Q2, still the highest among broad - based indexes [21]. - Most indexes' year - on - year growth rate of net profit attributable to shareholders in 2025Q2 declined quarter - on - quarter. The Science and Technology Innovation Board had a significant improvement in net profit in 2025Q2, and the ChiNext Index continued to lead other broad - based indexes in terms of growth rate [24]. - In terms of specific industries, in 2025Q2, the industries with the highest year - on - year growth rate of net profit attributable to shareholders were gaming (104%), steel (82%), precious metals (76%), etc. The industries with the largest decline were real estate (- 132%), coal (- 37%), etc. The industries with positive growth in 2025Q2 and an improvement compared with 2025Q1 were banks, insurance, etc. Combining the historical percentile of valuation, the industries with high performance growth and still some room for valuation are power equipment, new energy, gaming, and consumer electronics [29][30] 03 Convertible Bonds Follow Equities to Explore Locally Booming Sectors - The long - term cycle of convertible bonds is synchronized with equities. The short - term periodic recovery of convertible bond valuations provides signals for left - hand side position - adding and profit - taking. Short - term fluctuations may be leading and amplifying signals of equities. Recently, although convertible bond valuations have been actively adjusted, they are still at a relatively high level. After the holiday, attention should be paid to locally booming industries and performance - realizing targets. Convertible bond targets with good performance in 2025Q2 are concentrated in power equipment, electronics, etc. [45] - The All - A Index can basically explain most of the long - term fluctuations of convertible bonds. The regression results show that the performance of convertible bonds mainly follows the equity market, and the equity market trend can explain 91.4% of the price fluctuations of the convertible bond market. The convertible bond market follows equities in this round, and is less affected by the bond market [48][59] - The short - term fluctuations of convertible bond valuations provide signals for left - hand side position - adding and profit - taking. From June 23 to August 25, the active increase in convertible bond valuations was greater than that of the underlying stocks. Therefore, the convertible bond market entered the downward - oscillation cycle earlier than the equity market on August 27 and had a larger decline due to the return of valuations [61] - ETF share fluctuations have a relatively small impact on the price fluctuations of underlying convertible bond targets. Since September, the growth rate of convertible bond ETF shares has decreased significantly, which may mainly reflect sentiment and valuation [64] - Convertible bonds with good profitability have larger increases and are more resistant to declines. From June 23 to August 25, convertible bonds followed the underlying stocks in a sharp rise, with the growth sector leading. Some convertible bonds in individual sectors outperformed the underlying stocks, mainly concentrated in industries and targets with excellent performance. From August 25 to September 23, convertible bonds led the All - A Index in decline, and their subsequent performance was weaker than that of equities, mainly due to the periodicity of convertible bond valuation fluctuations [70][77] - The new energy sector under the goal of carbon peaking by 2030 may be one of the most certain trading directions in the next five years. The new energy vehicle penetration rate continues to increase, and the energy storage market has an important turning point. The report focuses on Keli Convertible Bonds and Hongfa Convertible Bonds in the new energy field [83] - Keli Convertible Bonds: Kodal Precision is the global leader in precision structural parts. The company's performance has been growing steadily. The convertible bond has a relatively large issuance scale, and the current price is around 140 yuan, with a conversion premium rate of 18.6%. It is an offensive convertible bond with high - quality underlying stocks and has no risk of forced redemption for the time being [87][89][92] - Hongfa Convertible Bonds: Hongfa Co., Ltd. is the world's largest relay manufacturer. The company's performance has been growing steadily. The convertible bond has a large issuance scale, and the current price is around 134 yuan, with a conversion premium rate of 18.2%.
