Group 1 - The core view of the report indicates that the Sci-Tech Innovation Board is expected to accelerate its rise, with a shift in leading sectors towards technology. The index is anticipated to continue its upward trend without significant resistance, as evidenced by the recent increases in major indices: Shanghai Composite Index up 1.67%, ChiNext Index up 2.76%, and Sci-Tech 50 Index up 4.63% [2][13]. - There is an imminent change in the leading structure of industries and themes. Last week, the leading sectors included construction materials (up 8.2%), coal (up 8.0%), steel (up 7.7%), and non-ferrous metals (up 6.7%), driven by themes such as "anti-involution" and hydropower station developments. However, the report suggests that the current phase of rapid price increases may be nearing its end, and market expectations for policy announcements may not exceed optimistic forecasts [3][14]. - The technology sector is expected to become the main focus of attention as the rapid rise of cyclical sectors comes to an end. The report emphasizes that technology will be the main line of the upcoming market trends [4][15]. Group 2 - The report maintains a positive outlook on artificial intelligence (AI) as a key theme, predicting significant marginal changes in the AI industry over the next 1-2 months. The release of new models, such as OpenAI's GPT-5, is expected to stimulate competition and drive growth in the sector [5][16]. - Within the AI theme, the report highlights strong potential in domestic computing power, AI applications, PCB-related sectors, and robotics. It argues that domestic computing power is crucial for national development and will likely receive continued policy support. AI applications are expected to gain traction as new models are released, while the PCB sector remains in an upward trend. Robotics, as a significant application of AI, is also projected to follow the growth of the AI sector [6][17][18].

1. Report Industry Investment Rating No information provided in the report. 2. Core Viewpoints of the Report - The high price and high valuation of convertible bonds have certain logical support from aspects such as bond floor and institutional behavior [3][7]. - The thick bond floor of convertible bonds currently may lead to an upward breakthrough in the average price as the stock market rises, and the existence of call - risk may cause the valuation and price of non - called convertible bonds to become more expensive [3][7]. - The option value of debt - like convertible bonds has increased, and their high - price and high - valuation state may be maintained, with the YTM possibly dropping to a very low level [3][7]. - As the equity market continues to strengthen and funds flow into equity - related assets, convertible bonds have become a tool for fixed - income plus funds to capture the beta of the equity market. If secondary bond funds replace primary bond funds as the marginal incremental form of fixed - income plus funds flowing into the market, the capital inflow into the convertible bond market may continue to increase [3][7]. - The average remaining term of the convertible bond market is gradually shortening, indicating an increase in both call and downward - revision probabilities. The high price of short - term debt - like convertible bonds currently contains a strong downward - revision expectation [3][7]. 3. Summary by Relevant Catalogs 3.1 Weekly Viewpoint and Outlook - The high price and high valuation of convertible bonds are supported by four clues, including the thick bond floor, the increase in the option value of debt - like convertible bonds, the strengthening of the equity market and the inflow of funds, and the shortening of the average remaining term of the convertible bond market [3][7]. 3.2 Convertible Bond Valuation - This week, the sentiment of convertible bonds and underlying stocks remained positive, with both rising significantly.

There was an obvious differentiation in the valuation of high - and low - rated convertible bonds, with the valuation of low - rated convertible bonds rising more [6][8]. - This week, convertible bonds continued to rise significantly following the underlying stocks, and the yield to maturity reached a new low since 2017, reporting - 5.09%. As of the latest, the conversion premium rate index, pure - bond premium rate index, and yield to maturity were 41.94%, 37.06%, and - 5.09% respectively, changing by - 1.31%, + 3.02%, and - 0.70% compared with last week, and their current quantile levels were at the 61.90, 62.70, and 0.00 percentiles since 2017 [6][10]. 3.3 Clause Tracking 3.3.1 Redemption - This week, convertible bonds such as Yingji, Chujiang, and Liancheng issued early redemption announcements. Currently, there are 22 convertible bonds that have issued call or maturity redemption announcements but have not yet delisted, and the potential conversion or maturity balance of call and maturity convertible bonds among those not delisted is 5 billion yuan [6][14]. - There are currently 52 convertible bonds in the redemption process, 14 of which are expected to meet the redemption conditions next week. Also, 4 convertible bonds issued non - redemption announcements this week [14][17][19]. 3.3.2 Downward Revision - This week, Zhongzhuangzhuan 2 and Jinneng convertible bonds proposed downward revisions, and Jingao convertible bond announced a downward revision to the bottom.

还有易明医药，今天干脆涨停了，换手率23.9%，成交额9.49亿，3家机构凑在买一、买三、买四的位置，合计净买入2700多万。涨停板上机构还愿意掏钱， 说明短期趋势可能被他们认可，但也别光高兴，得看看这涨停是突发消息还是真有业绩撑着，毕竟咱做中长线，得看实在的东西。 更有意思的是中化岩土，今天跌停了，成交额21.74亿，换手率25.9%，按理说跌成这样该没人敢碰吧？可偏偏有两家机构在买二、买四的位置往里砸钱，净 买入近2500万。巧的是深股通在这票上净卖出5400多万，机构和深股通对着干，这种分歧往往藏着机会或风险，得跟踪看看后续谁能占上风。 再看机构净卖出的票，头三名挺扎眼。昂利康一天振幅快20%，还跌了近10%，4家机构排在卖一到卖五的位置，合计净卖出3个亿。这种大振幅加暴跌，机 构跑这么快，大概率是在避险，怕后续还有波动，咱散户碰这种票可得攥紧缰绳。 华新水泥也被机构甩了1.77亿，还跟着沪股通净卖出4900多万，不过营业部席位倒净买入5700多万。这就有意思了，机构和外资在卖，游资却在接，说明不 同资金对这票的看法差得远，可能和近期水泥行业的预期变化有关，咱得看看是不是行业逻辑真的变了。 各位老铁，我 ...

Report Industry Investment Rating No relevant content provided. Core Viewpoints of the Report - A-share index has a clear bottom line, and the trading volume in the two markets has increased, driving the index to fluctuate upwards. The "anti-involution" policy has led to a full recovery of theme stocks. The 1.2 trillion hydropower project in the Yarlung Zangbo River has directly promoted the entire infrastructure industry chain such as water conservancy and building materials to strengthen. The market shows the characteristic of "blue-chip stocks setting the stage, and theme stocks performing". Futures index should be intervened after a pullback [3]. - Although the international situation is complex, the current market expectations are sufficient, and the disturbances caused by Sino-US and Iran-Israel issues are limited. The US has lifted the restrictions on H20 chips. The external influence is mainly the Fed's interest rate decision. A rate cut is beneficial for the appreciation of the RMB, the return of foreign capital, and the inflow of new incremental funds, which may start as early as September. Currently, policies to stabilize the capital market are positive, the bottom line of the stock index is clear, and new technologies and new consumption are promoting the economic expectation to stabilize and recover. After the risk-free interest rate drops to a low level, the entry of medium and long-term funds and residents into the market will enter a new cycle. A breakthrough must be accompanied by an increase in trading volume. This week, the trading volume in the two markets exceeded 1.5 trillion (MA5), and the index still has upward momentum [4].

New RMB loans were 2.24 trillion yuan, an increase of 110 billion yuan year-on-year, and short-term corporate loans became the main driving force. The growth rate of M2 rebounded, and M1 improved significantly. In June, the year-on-year growth rate of M2 was 8.3% (a month-on-month increase of 0.4 pct), mainly driven by the low-base effect (deposit diversion caused by manual interest compensation supervision in the same period in 2024) and an increase in corporate deposits [17].
