Hot Sectors:
Lithium Battery Concept Explodes Across the Board
The lithium battery concepts, including lithium iron phosphate, sodium-ion batteries, solid-state batteries, and electrolytes, all surged, with multiple stocks such as Zhongyi Technology and Weiling Co., Ltd. hitting the daily limit, and CATL rising over 6%.
In terms of news, CATL recently delivered a surprising performance report to the market. Subsequently, mainstream institutions such as HSBC Qianhai, Nomura, and Jefferies collectively raised their target prices.
Optical Fiber Concept Repeatedly Strengthens

Chemical Sector Experiences Fluctuating Rebound
The chemical sector experienced a fluctuating rebound, with Jinpu Titanium Industry, Yuegui Co., Ltd., and Baichuan Co., Ltd. hitting the daily limit.
In terms of news, the ongoing geopolitical conflicts in the Middle East and the obstruction of navigation in the Strait of Hormuz have pushed up international oil prices, providing support for chemical product costs. Institutions pointed out that Iran is an important global exporter of sulfur, and the already tight global supply situation has worsened, increasing the possibility of further cost increases for sulfate titanium dioxide, while the likelihood of price declines has decreased.
Superhard Materials Concept Continues to Be Strong
The superhard materials concept continues to be strong, with Huanghe Xuanfeng hitting the daily limit for two consecutive days, and stocks such as Lili Diamond, Sifangda, and Huifeng Diamond following suit.
Kaiyuan Securities' research report pointed out that synthetic diamonds, with their extreme thermal conductivity, ultra-high hardness, and excellent material stability, are entering the thermal management and high-end manufacturing sectors of computing systems, with the industry transitioning from &#34;traditional industrial consumables and consumer substitutes&#34; to &#34;high-end manufacturing materials in the AI era.&#34;
Institutional Debate on Future Market:
Everbright Securities: External disturbances may gradually weaken, and market performance is worth looking forward to
The impact of external disturbances may gradually weaken, and market performance is worth looking forward to. Although the conflict trends in the Middle East still carry a high degree of uncertainty, the period of marginal emotional impact on the domestic market may have passed. The market may return to its own rhythm in the future. From the current situation, the overall tone of the national &#34;Two Sessions&#34; is stable, which is expected to lay a solid policy foundation for the stock market's rise. In addition, the market will enter a period of intensive data and policy verification in the coming month. Overall, the opportunities in the equity market are still greater than the risks, and performance is worth anticipating.
CITIC Construction Investment: Optical modules are expected to remain prosperous
Compared to traditional cloud computing networks, AI training networking is shifting from leaf spine architecture to fat tree architecture, significantly increasing the number of switches and optical modules. As communication data volume increases, the rate requirements for optical modules are also higher. The 800G optical module will start to ramp up production in 2023, maintaining rapid growth from 2024 to 2026; the 1.6T optical module will begin shipping in 2025, with a ramp-up expected in 2026, ushering the entire optical module industry chain into a prosperous cycle of rising volume and price.
CITIC Securities: Short-term uncertainties are still expected to drive oil shipping rates upward
CITIC Securities research report states that the blockage of the Strait of Hormuz is reshaping the energy landscape. According to Kpler data, about 10 oil tankers are expected to dock at Yanbu Port, raising concerns about &#34;price without market,&#34; and the number of VLCCs is expected to further increase. The shipping distance from Yanbu Port/Hormuz Strait to Qingdao Port has increased by about 18%. Considering the shipping capacity of Yanbu Port and Fujairah Port, the demand gap is seeking to be supplemented by the U.S. Gulf, further expanding the shipping distance growth to over 30%. In the short term, strategic reserves will be released, and supply chain adjustments will be made to hedge against the geopolitical impacts of the U.S.-Iran conflict, but seeking partial restoration of the passage capacity in the Strait of Hormuz remains a solution. After the restrictions are lifted, compensatory demand is expected to keep tanker transportation at high rates; if vessel utilization is limited, rates may further rise. Attention should be paid to the historically increased concentration of VLCC capacity, and the pricing mechanism for rates is being reshaped. On one hand, &#34;quasi-alliance&#34; enhances shipowners' bargaining power, while on the other hand, alliances formed by Sinokor, MSC, and Trafigura, along with the rental surplus of their fleets, further enhance the capacity for alliance expansion. Short-term uncertainties are still expected to drive rates upward, without changing the expectation that profits for leading oil shipping companies may reach new highs in 2026
