Report Summary 1. Report Industry Investment Rating No information provided in the report. 2. Core Viewpoints - The Chinese economy shows new resilience with the dual records of "trillion - kilowatt - hour electricity consumption and trillion - yuan trading volume". The policy combination is effective, and a positive cycle has been formed [1]. - The domestic stock market is in a resonance period of "policy bottom + fund bottom + valuation bottom", and the market trend is likely to continue, but investors need to adapt to accelerated sector rotation and structural differentiation [2]. - Various commodities have different trends affected by factors such as supply and demand, geopolitics, and policies [2][3]. 3. Summary by Relevant Catalogs a. Chief Comment - A - share market major indices are rising, with the Shanghai Composite Index, Shenzhen Component Index, and ChiNext Index up 12.51%, 14.45%, and 21.19% respectively this year. The trading volume of the Shanghai and Shenzhen stock markets frequently exceeds 2 trillion yuan, and the margin trading balance is at a historical high [1]. - In July, the total social electricity consumption reached 1.0226 trillion kilowatt - hours, a year - on - year increase of 8.6%, doubling compared to a decade ago [1]. - China's foreign trade maintains a steady - to - improving trend, with the cumulative import and export growth rate rising month by month, achieving a 3.5% increase in the first seven months [1]. b. Key Varieties - **Equity Index**: The equity index shows differentiation. The domestic liquidity is expected to remain loose in 2025, and more incremental policies may be introduced in the second half of the year. The external risks are gradually easing. The CSI 500 and CSI 1000 indices with more technology - growth components are more offensive, while the SSE 50 and CSI 300 indices with more dividend - blue - chip components are more defensive [2]. - **Precious Metals**: Gold and silver are in a volatile state. The market is waiting for signals from Powell's speech at the Jackson Hole meeting. The long - term drivers of gold still provide support, and the overall trend of gold and silver may be volatile with the increasing expectation of interest rate cuts [3]. - **Crude Oil**: International oil prices continue to rise due to the decline in US crude oil inventories, strong oil demand, and the uncertainty of efforts to end the Russia - Ukraine conflict. The hurricane season in 2025 is relatively calm so far [3]. c. Main News Concerns - **International News**: The EU and the US announced details of a new trade agreement. The US will impose a 15% tariff on most EU goods, while the EU will cancel tariffs on US industrial products and provide preferential market access for US seafood and agricultural products. The EU plans to purchase $750 billion of US liquefied natural gas, oil, and nuclear products and $40 billion of US AI chips by 2028 [5]. - **Domestic News**: The State Council agreed in principle to the "Development Plan for the Open and Innovative Development of the Whole Biopharmaceutical Industry Chain in the China (Jiangsu) Free Trade Pilot Zone" [6]. - **Industry News**: In July, the total social electricity consumption exceeded 1 trillion kilowatt - hours for the first time globally, with a significant increase in the proportion of new energy [7]. d. Morning Comments on Main Varieties - **Financial**: - **Equity Index**: The US three major indices fell. The domestic equity index shows differentiation, and the market trading volume is 2.46 trillion yuan. The market is in a favorable period, but investors need to pay attention to sector rotation [10]. - **Treasury Bonds**: Treasury bonds rebounded after reaching the bottom. The central bank's monetary policy is loose, which supports short - term treasury bond futures prices, but the stock - bond seesaw effect may suppress the bond market, and the cross - variety spread may widen [11]. - **Energy and Chemicals**: - **Crude Oil**: Oil prices continue to rise due to factors such as inventory decline and demand. The hurricane has not affected key oil and gas infrastructure. The number of initial jobless claims in the US increased, and the OPEC's production increase situation needs to be monitored [12]. - **Methanol**: Methanol prices fell at night. Coastal methanol inventories increased significantly, and the short - term trend is mainly bullish [13]. - **Rubber**: The price of rubber is mainly supported by the supply side. The demand side is weak, and the short - term trend is expected to continue to correct [15]. - **Polyolefins**: Polyolefin futures rebounded. The market is mainly driven by supply and demand. The inventory is slowly being digested, and the terminal demand may pick up in mid - to - late August [16]. - **Glass and Soda Ash**: Similar to polyolefins, the market is driven by supply and demand, and attention should be paid to the autumn stocking market and supply - cost changes [17]. - **Metals**: - **Precious Metals**: Gold and silver are volatile, waiting for signals from Powell's speech. The long - term drivers of gold still support the price, and the overall trend may be volatile [18]. - **Copper**: Copper prices may fluctuate within a range due to factors such as low concentrate processing fees and stable downstream demand [19]. - **Zinc**: Zinc prices may fluctuate widely. The supply of concentrates has improved, and the smelting supply may recover [20]. - **Lithium Carbonate**: The short - term trend is affected by sentiment. The supply is expected to increase slightly in August, and the demand is also expected to increase. The inventory situation is complex, and the price may have room to rise if the inventory is depleted [21]. - **Black Metals**: - **Iron Ore**: The demand for iron ore is supported by strong production. The global iron ore shipment has decreased recently, and the mid - term supply - demand imbalance pressure is large. The market is expected to be volatile and bullish [22]. - **Steel**: The supply pressure of steel is gradually emerging, but the supply - demand contradiction is not significant. The market is expected to be volatile and bullish [23]. - **Coking Coal and Coke**: The futures of coking coal and coke are in a wide - range volatile state, with intense long - short competition [24]. - **Agricultural Products**: - **Protein Meal**: Bean and rapeseed meal are weakly volatile at night. The US soybean production is expected to be good, but the reduction in planting area provides support. The domestic market is expected to be range - bound [25]. - **Oils and Fats**: Oils and fats rose at night. The production and export of Malaysian palm oil increased in August, but there are risks of a short - term decline due to factors such as US biodiesel news [26]. - **Sugar**: International sugar prices are expected to be volatile as the global sugar market is about to enter the inventory - accumulation stage. The domestic sugar market is supported by high sales - to - production ratios and low inventories, but import pressure may drag down prices [27]. - **Cotton**: US cotton prices fell. The domestic cotton market supply is relatively tight, but the demand is in the off - season. The short - term trend is expected to be volatile and bullish with limited upside space [28]. - **Shipping Index**: - **Container Shipping to Europe**: The EC index is weakly volatile. The freight rate has been decreasing, and the short - term decline may slow down. The high - volume capacity supply may increase the downward pressure on freight rates during the off - season [29].
