Group 1: Market Performance - As of August 20, the Shanghai Composite Index reached a 10-year high of 3766.21 points, while most government bond futures declined [1]. - From August 1 to August 18, the Shanghai Composite Index rose from 3568 to 3728 points, with corresponding increases in government bond yields across various maturities [2]. - On August 18, major stock indices hit recent highs, coinciding with significant declines in government bond futures, with the 30-year main contract dropping by 1.33% [3].

Overall Investment Recommendations - The report provides investment strategies for various commodities and financial products, including stocks, bonds, and multiple futures contracts [1]. Stock Index Futures - The A-share market had a narrow - range oscillation on Tuesday, with the North - Securities 50 reaching a new high. The trading volume of the Shanghai and Shenzhen stock markets slightly decreased to 2.64 trillion yuan but remained above 2 trillion. The comprehensive and communication industries led the gains, while the national defense and military industry, and non - bank financial sectors led the losses [1]. - Stock index futures adjusted following the spot index, with a larger decline in futures than in the spot, and the basis continued to widen. Although there is some resistance to short - term upward movement as the market breaks previous highs, the capital side remains active, and the trading enthusiasm continues to rise. As of August 18, the margin trading balance exceeded 2.1 trillion yuan, achieving six consecutive increases. Long - term positive factors such as the transfer of household deposits and the bottom - up recovery of corporate profits remain unchanged. It is recommended to maintain a long - position mindset [1]. Treasury Bonds - The bond market showed signs of stabilization and a slight rebound, with the T - contract performing weakly. The domestic market had a net capital injection, but due to the tax period, the cost of funds continued to rise. Data was scarce, and the expectation of policy intensification remained optimistic [1]. - Considering the Fed's interest - rate cut rhythm and the impact of the domestic monetary policy report, the expectation is relatively cautious. The stock - bond seesaw effect is still significant, and the market's risk appetite remains optimistic. The bond market is more sensitive to negative news. Although the bond market's recent decline was rapid, new positive factors are limited, and the upward pressure may continue. A cautious and bearish view is recommended [1]. Commodity Futures Basic Metals - **Aluminum and Alumina**: The domestic economic data is mixed, but policy expectations remain optimistic. Overseas tariffs have weakened, and the market is watching the Fed's stance at the global central bank meeting. The US has expanded the scope of aluminum tariff increases, which has a limited impact on domestic exports. Alumina's over - supply situation remains unchanged, and the market's bullish sentiment has weakened significantly, with continuous upward pressure on prices. For Shanghai aluminum, the short - term demand expectation is weak, but the medium - term support is clear [3]. - **Copper**: The domestic economic data is mixed, but policy expectations are optimistic. Overseas tariffs have weakened, and the market is focused on the Fed's attitude. The smelting processing fee is slowly rebounding but remains negative, and the global copper - mine supply shortage persists. Although domestic and overseas refined copper production continues to grow, and there are positive expectations for consumption, the short - term upward momentum is limited, and the price will continue to oscillate. However, in the medium - term, the upward trend is unchanged [3]. - **Nickel**: The supply of nickel ore is sufficient, and port inventories are accumulating. Although Indonesia is cracking down on illegal mining, the ore price is still supported. The production capacity at the smelting end is abundant, and the trading is dull. Refined nickel production remains high, and the inventory - accumulation trend continues. As the Fed's interest - rate cut expectation cools, the nickel price has low volatility, with resistance from over - supply and support from potential ore - supply issues. Selling call options is a relatively favorable strategy [3][4]. Energy and Chemicals - **Crude Oil**: Geopolitical factors have led some funds to take a wait - and - see attitude towards the Russia - Ukraine conflict. The API weekly data showed a decline in US crude - oil inventories, but the market reaction was muted. As the peak consumption season for the crude - oil market is ending, the expectation of supply over - capacity is strengthening, and the short - term positive factors are lacking. The oil price will continue to be weak [5]. - **Methanol**: This week, the signing volume of northwest sample enterprises reached the lowest level since May, and the futures price dropped rapidly, reducing the downstream's purchasing willingness. Although there are many new maintenance devices, and the factory operating rate is low, providing support for the spot price, as the negative impact of increased arrivals is gradually released, the further decline space for futures is limited [7]. - **Polyolefins**: Recently, there have been more new maintenance devices for PE, and its operating rate is at a medium level, while PP's maintenance devices have restarted, and its operating rate has returned to a high level. Considering production and new capacity, PE's supply pressure is lower than PP's, and PE's demand is also better. It is recommended to hold a long position in the L - PP spread [7]. - **Soda Ash and Glass**: For soda ash, the anti - involution policy has no clear signal, and the policy - intensity expectation is decreasing. The over - supply situation is obvious, with daily production slightly decreasing to 11.07 million tons, and the far - reaching energy's second - phase device may be put into operation in September, intensifying the over - supply. It is recommended to short the 01 contract. For float glass, real - estate sales and completion are weak, and although the sales - to - production ratio in some regions has increased, without effective supply - side constraints, the fundamentals are difficult to improve substantially. It is recommended to adopt a bearish strategy [5]. - **Coal and Coke**: For coking coal, after the coal - mine production self - inspection, the raw - coal output is still low, and the inventory - reduction rate has slowed down. The environmental protection restrictions on steel and coking enterprises have restricted demand, and the coal price is under pressure. For coke, some coking enterprises have received production - restriction notices, and steel mills in the Beijing - Tianjin - Hebei region also have production - reduction expectations. The fundamentals are expected to weaken, and the price will oscillate and decline [5]. Agricultural Products - **Cotton**: Domestically, there is a strong expectation of a bumper harvest, and the market's expectation for the new - cotton purchase price is pessimistic. Overseas, the USDA August report adjusted the supply and demand for the 2025/2026 season, and the ending inventory decreased. The inventory of imported cotton in major ports has decreased, and the downstream industry has slightly improved. The market is watching whether the downstream will continue to improve during the traditional peak season [7]. - **Rubber**: The automotive market benefits from policy support, and tire - enterprise operating rates are good. Although the ANRPC has entered the traditional production - increasing season, the new - rubber output rate is lower than expected, and the raw - material price in the production area is firm. The supply - demand structure of natural rubber is gradually improving, and the port inventory is decreasing, providing support for the rubber price [7]. Steel and Iron Ore - **Rebar**: The anti - involution policy has no clear implementation signal, and the policy - intensity expectation is decreasing. The fundamentals of rebar are showing more signs of weakening. Regional and phased production restrictions have limited impact on supply, and the crude - steel reduction policy has not been implemented. Steel mills' profits are acceptable, and production is expected to resume after the military - parade production restrictions end. Real - estate data is weak across the board, and the inventory of rebar has started to accumulate rapidly. It is recommended to hold a short position in the 01 contract and pay attention to the support at around 3100 [4]. - **Hot - Rolled Coil**: Similar to rebar, the anti - involution policy has no clear signal, and the fundamentals of steel products are weakening. The military - parade production restrictions in the north mainly affected sintering and rolling processes, and the actual implementation depends on weather conditions. Steel mills' profits are good, and production is likely to resume after the restrictions end. The high coil - to - rebar spread may prompt the transfer of molten iron from rebar to hot - rolled coil. Although the current demand for plates is more resilient than that for construction steel, the inventory - accumulation rate of plates has also accelerated. The downward pressure on the hot - rolled coil price is increasing, and the near - term contract is weaker than the far - term one [4]. - **Iron Ore**: The military - parade production restrictions mainly affected sintering and rolling, and the actual implementation depends on weather conditions. Steel mills' profits are good, and production is expected to resume after the restrictions end. However, the weakening of the steel fundamentals may put pressure on the iron - ore price. It is expected that the iron - ore price will follow the steel price, with the 01 - contract price ranging from 750 to 810. It is recommended to short at high prices within this range [4][5].

Group 4: Future Outlook - The current market environment shows weak support for bond bulls, with expectations of limited downward movement in bond prices due to a combination of slow domestic demand recovery and a generally loose liquidity environment [5]. - Despite short-term pressures on the bond market, there is a belief that fundamental and liquidity support will prevent overly pessimistic outlooks for the bond market in the medium to long term [5].
