For eggs, short on rallies for near - term contracts; for apples, use a light - position positive spread strategy; for corn, short on far - term contracts; for dates, stay on the sidelines; for pigs, be cautious and short on near - term contracts [30][33][35][37][39][40][41]. 4. **Energy and chemicals**: For crude oil, consider shorting on rallies; for fuel oil, it follows crude oil and has a complex fundamental situation; for plastics, expect limited rebound space; for rubber, it is slightly strong in the short term; for methanol, it will continue to be weakly volatile; for asphalt, it follows crude oil; for LPG, it is prone to fall and difficult to rise; for pulp, observe the inventory and trading volume; for logs, observe and consider hedging on rallies; for urea, the futures price is weak; for synthetic rubber, it is slightly strong in the short term [44][45][46][47][48][51][53][54][55][56][57].

However, the on - balance - sheet new RMB loans turned negative in July [14]. Treasury Bond Futures - Strategy: Consider a steepening strategy. The money market is loose, and the bond market first weakened and then strengthened. The long - end bonds can be considered to maintain a weakly volatile and bearish view, and the steepening of the yield curve is still relatively advantageous [15][16]. Black Metals - **Steel and Ore**: Policies are becoming milder, supply and demand contradictions are not prominent, and prices are expected to be volatile. Steel mill profits are mixed, and iron ore prices are also volatile [16][17][18]. - **Double - coke**: Prices may enter a high - level consolidation phase. The supply of coking coal is expected to be tight in the short term, but there is also downward pressure [18][19]. - **Double - silicon**: The current price is in a reasonable range, and the medium - term supply - demand logic is weak. Avoid chasing short positions without non - fundamental positive disturbances [19].

Alumina prices may be strong in the short term but face supply surplus pressure in the long term [24]. - **Zinc**: Social inventories are increasing, and zinc prices are expected to weaken after the macro influence fades [25]. - **Industrial Silicon**: The supply - demand situation has improved marginally, and the price is expected to be volatile, but there is pressure from industrial hedging [26][27]. - **Polysilicon**: In the short term, it may return to the contradiction between fundamentals and warehouse receipts, with wide - range fluctuations [28]. Agricultural Products - **Cotton**: Short - term watch and long - term short on rallies due to low downstream demand and new crop production pressure [30][31][32]. - **Sugar**: Domestic sugar stocks are low, but the increase in processed sugar may restrict prices. Pay attention to short - covering opportunities during stocking [33][34][35]. - **Eggs**: The Mid - Autumn Festival peak season is approaching, but the supply pressure is large. Short on rallies for near - term contracts and consider a short 10 - long 12 spread strategy [35][36]. - **Apples**: Use a light - position positive spread strategy. Pay attention to the price changes of early - maturing apples and new - season Fuji apples [37]. - **Corn**: Short on far - term contracts. The market sentiment is bearish, but there is support at the bottom [38][39]. - **Dates**: Stay on the sidelines as the spot market in Hebei is weak [40]. - **Pigs**: Be cautious and short on near - term contracts. The supply pressure is high, and pay attention to the development of African swine fever [40][41]. Energy and Chemicals - **Crude Oil**: Consider shorting on rallies as it is likely to enter a supply - surplus pattern [44]. - **Fuel Oil**: Follows crude oil. The current fundamental situation is complex, with factors such as power demand in the Middle East and low - sulfur fuel oil demand affecting it [45]. - **Plastic**: The rebound space is expected to be limited, and it is recommended to prevent callback risks [46]. - **Rubber**: Slightly strong in the short term, but be cautious when chasing highs [47]. - **Methanol**: Continue to be weakly volatile due to the contradiction between tight inland supply and loose port supply [48][49]. - **Caustic Soda**: The spot price in Shandong has support, but the futures price has limited upward space [50]. - **Asphalt**: Follows crude oil, and its own fundamentals are in the off - season, with slow inventory reduction [51]. - **Polyester Industry Chain**: Unilateral prices are expected to follow the cost downward. Consider a strategy of going long on MEG and short on PTA [52]. - **LPG**: Supply is abundant, and demand is expected to decline in the medium - long term, making the price prone to fall [53]. - **Pulp**: The market trading has improved, and the price has followed the increase. Observe the inventory and trading volume [54]. - **Logs**: The price is affected by capital, and it is recommended to observe and consider hedging on rallies [55]. - **Urea**: The futures price is weak due to weak fundamentals [56]. - **Synthetic Rubber**: Slightly strong in the short term, be cautious when chasing highs [57].
