Report Industry Investment Ratings No relevant content provided. Core Views of the Report - The report analyzes various futures markets, including bonds, stocks, precious metals, and commodities. It suggests that investors should remain cautious in the bond market, be optimistic about the long - term performance of Chinese equity assets, and consider long - positions in gold futures. For different commodities, it provides specific trading strategies based on their supply - demand fundamentals, cost factors, and market sentiment [6][8][11]. Summary by Related Catalogs Bonds - **Market Performance**: On the previous trading day, Treasury bond futures showed a mixed performance. The 30 - year, 10 - year, 5 - year, and 2 - year Treasury bond futures had different price changes. The central bank conducted 530.8 billion yuan of reverse repurchase operations on April 30, with a net injection of 422.8 billion yuan. In April, the manufacturing PMI declined, while the non - manufacturing and composite PMIs remained in the expansion zone [5]. - **Analysis and Strategy**: The external environment is favorable for Treasury bond futures, but the current yield is relatively low. The Chinese economy shows a stable recovery trend, and there is room for domestic demand policies. Tariffs may be adjusted repeatedly, so investors are advised to remain cautious, expecting increased volatility [6][7]. Stocks - **Market Performance**: On the previous trading day, stock index futures showed mixed results. The CSI 300, SSE 50, CSI 500, and CSI 1000 stock index futures had different price changes [8]. - **Analysis and Strategy**: Although tariffs disrupt the domestic economic recovery rhythm and global recession risks increase, domestic asset valuations are low, and there is policy - hedging space. The report is optimistic about the long - term performance of Chinese equity assets and suggests considering long - positions in stock index futures [8][9]. Precious Metals - **Market Performance**: On the previous trading day, gold and silver futures prices declined. In April, the US non - farm payrolls increased, and the unemployment rate remained stable. The US GDP in the first quarter declined [10]. - **Analysis and Strategy**: The complex global trade and financial environment, potential central bank policy easing, and tariff impacts are expected to drive up gold prices. The long - term bullish trend of precious metals continues, and investors are advised to buy gold futures on dips [10][11][12]. Steel and Related Products - **Rebar and Hot - Rolled Coil**: On the previous trading day, rebar and hot - rolled coil futures showed weak oscillations. The real - estate downturn suppresses rebar demand, but the peak - season demand may provide short - term support. The valuation is low, and the price has support at the previous low. Investors can look for short - selling opportunities on rebounds and manage positions carefully [13]. - **Iron Ore**: On the previous trading day, iron ore futures oscillated. The increase in iron ore demand and the decrease in supply and inventory support the price. The valuation is relatively high among black - series products, and the price has support at the previous low. Investors can look for long - buying opportunities at low levels and set stop - losses [14][15]. - **Coking Coal and Coke**: On the previous trading day, coking coal and coke futures continued to decline. Coking coal supply is loose, and coke demand has improved slightly, but the possibility of price increases is low. The price may test the previous low again. Investors can look for short - selling opportunities on rebounds [17]. - **Ferroalloys**: On April 30, manganese - silicon and silicon - iron futures prices declined. Manganese - ore supply may be disrupted, and the supply of ferroalloys is still high while demand is weak. With the arrival of the peak season for steel demand, the supply - demand situation is improving. Investors can consider call options for manganese - silicon and exiting short - positions for silicon - iron [19][20]. Energy - **Crude Oil**: On the previous trading day, INE crude oil prices dropped significantly. The CFTC data shows changes in WTI crude oil and natural gas futures positions. The number of US oil and gas rigs decreased, and OPEC + agreed to increase oil supply in June. The report suggests waiting and seeing for crude oil futures [21][22][23]. - **Fuel Oil**: On the previous trading day, fuel oil prices followed crude oil and dropped significantly. The market structure of high - sulfur fuel oil has slightly improved. The possible relaxation of US sanctions on Russia and the expected signing of tariff agreements have different impacts on fuel oil prices. The report suggests short - selling fuel oil futures [23][24]. Rubber - **Synthetic Rubber**: On the previous trading day, synthetic rubber futures prices declined. Supply pressure persists, demand improvement is limited, and the cost has weakened. The short - term trend is expected to be weak [25][26]. - **Natural Rubber**: On the previous trading day, natural rubber futures prices showed mixed results. The expected increase in global supply and the impact of tariffs on demand are expected to keep the price in a weak oscillation [27][28]. Chemical Products - **PVC**: On the previous trading day, PVC futures prices declined. Supply pressure has eased marginally, demand is weakly recovering, and the price is expected to oscillate at the bottom [29][30]. - **Urea**: On the previous trading day, urea futures prices increased. The approaching summer fertilizer - preparation period may increase demand, but supply elasticity is high. The potential Indian tender and domestic export - policy adjustment may affect the price. Investors should pay attention to export changes [31][32]. - **PX**: On the previous trading day, PX futures prices declined. PX device maintenance has reduced the load, and downstream PTA demand has improved. The short - term crude - oil price is under pressure, and PX is expected to oscillate with the cost [33]. - **PTA**: On the previous trading day, PTA futures prices declined. The planned maintenance of PTA devices and the expected improvement in exports may provide some support, but the external crude - oil price is under pressure. The price is expected to oscillate [34]. - **Ethylene Glycol**: On the previous trading day, ethylene glycol futures prices declined. The restart of coal - based devices and high inventory limit the price rebound. The price is expected to oscillate at the bottom [35]. - **Short - Fiber**: On the previous trading day, short - fiber futures prices declined. The supply load is high, downstream demand is weak, and the price is expected to follow the cost and oscillate [36]. - **Bottle Chips**: On the previous trading day, bottle - chip futures prices increased. The raw - material price is under pressure, and the supply - demand fundamentals lack drivers. The price is expected to follow the cost and oscillate [37]. - **Soda Ash**: On the previous trading day, soda - ash futures prices declined. Device maintenance in May may cause short - term price adjustments, but the supply is still high, and the market is weak in the short term [38][39]. - **Glass**: On the previous trading day, glass futures prices declined. The production line is at a low level, inventory changes little, and demand is weak. The post - holiday market sentiment is expected to be weak [40]. - **Caustic Soda**: On the previous trading day, caustic - soda futures prices increased. The demand from the alumina and non - alumina industries is limited, but device maintenance in May may provide some drivers [41][42]. - **Paper Pulp**: On the previous trading day, paper - pulp futures prices declined. Inventory is accumulating, supply is increasing, and market trading is light. The price reflects a pessimistic outlook [43]. - **Lithium Carbonate**: On the previous trading day, lithium - carbonate futures prices declined. The supply is high, demand is weakening, and the price is expected to be weak [44][45]. Non - Ferrous Metals - **Copper**: On the previous trading day, Shanghai copper futures prices dropped significantly. Although the ICSG expects a copper supply surplus, the demand may recover after the tariff friction eases. The report suggests long - buying Shanghai copper futures [46][47]. - **Tin**: On the previous trading day, LME tin prices increased. The复产 of major mines may ease the supply shortage, but the impact of Sino - US trade on the downstream electronics market remains. The price is expected to be under pressure and oscillate weakly [48]. - **Nickel**: On the previous trading day, LME nickel prices increased. The supply of nickel ore is tightened, and the cost provides support, but the downstream acceptance of high prices is low. The demand may weaken in the off - season, and the market is expected to remain in a supply - surplus situation. Investors are advised to wait and see [49]. - **Industrial Silicon/Polysilicon**: On the previous trading day, industrial - silicon and polysilicon futures prices declined. The supply - demand imbalance persists, and the market is pessimistic about the future demand. The prices are expected to be weak [50][51]. Agricultural Products - **Soybean Oil and Soybean Meal**: On April 30, soybean - meal futures prices declined, and soybean - oil futures prices increased. The smooth progress of US soybean planting and the Brazilian soybean harvest increase supply. The demand for soybean oil and soybean meal is expected to increase slightly. The report suggests waiting and seeing for soybean - meal futures and considering call options for soybean - oil futures at the bottom [52][53]. - **Palm Oil**: Malaysian palm - oil prices declined. The inventory may increase, and the domestic import volume has changed. The report suggests considering the opportunity to expand the spread between soybean oil and palm oil [54][55][56]. - **Rapeseed Meal and Rapeseed Oil**: Canadian rapeseed prices declined. China has imposed tariffs on Canadian rapeseed products. The inventory of rapeseed, rapeseed meal, and rapeseed oil has changed. The report suggests considering long - buying rapeseed meal after a pullback [57][58]. - **Cotton**: During the holiday, the external cotton price increased. The planting progress in the US and China has been reported. The high - level tariffs between China and the US affect demand, and the domestic downstream demand is weak. The report suggests waiting and seeing [59][60][61]. - **Sugar**: During the holiday, the external raw - sugar price fluctuated slightly. Brazil is entering the production - acceleration period, and the Indian sugar production is lower than expected. The domestic sugar inventory is neutral, and the import volume is low. The report suggests waiting and seeing [62][63][64]. - **Apples**: On the previous trading day, domestic apple futures prices oscillated. The inventory is low, and the consumption is good. The new - year production is expected to increase. The report suggests waiting and seeing [66][67][68]. - **Pigs**: During the holiday, the pig price increased first and then stabilized. The supply is expected to increase after the holiday, and the demand may weaken. The price is expected to oscillate weakly first and then strengthen. The report suggests waiting and seeing [69][70][71]. - **Eggs**: During the holiday, the egg price increased slightly. The supply is expected to increase in May, and the price may decline after the Dragon Boat Festival. The report suggests holding reverse spreads [72]. - **Corn and Starch**: On April 30, corn and corn - starch futures prices increased. The US corn planting is progressing smoothly, and the Brazilian corn production is expected to increase. The domestic corn supply is under pressure in the short term, and the demand is slightly increasing. Corn - starch production and demand are weak, and the inventory is high. The report suggests waiting and seeing [73][74]. - **Logs**: On the previous trading day, log futures prices declined. The supply is affected by holidays and weather, and the demand from the real - estate sector is weak. The market has no obvious drivers, and the price is expected to be weak [75][76][77].

1. Report Industry Investment Rating No relevant content provided. 2. Core Views of the Report - For silicon manganese, the industry fundamentals have not improved significantly, cost - end support is insufficient, and high inventory suppresses price increases. The market may continue to seek a bottom and is expected to be weak in the short term, with the main contract reference range of [5600, 6000] [5] - For silicon iron, the supply - demand contradiction is gradually alleviating, the industry's production reduction progress is accelerating, but the inventory level is still relatively high. The market may continue to seek a bottom and is expected to be weak in the short term, with the main contract reference range of [5400, 5850] [46] 3. Summary according to Relevant Catalogs 3.1 Silicon Manganese 3.1.1 Supply and Demand Analysis - Supply: In April, production and operating rates declined significantly. It is expected that the total silicon manganese output in April will be around 810,000 tons. Although the production decline in each production area has slowed down compared with the previous period, the daily average output in Inner Mongolia is still at a relatively high level in the same period, and the operating rate in Yunnan is also at a high level in the same period [4][18] - Demand: In April, the substantial increase in hot metal production provided rigid support for the demand for silicon manganese. However, in steel tenders, the procurement prices of mainstream steel mills decreased, and the overall price - pressing sentiment was strong. Recently, news of production cuts has disturbed the market [4] 3.1.2 Manganese Ore Overview - Price: Manganese ore prices have not stopped falling, and the decline of oxide ore is obvious. Although the inquiry enthusiasm at ports has increased recently, the overall purchasing mentality is still cautious [4] - Inventory: Port inventory has continued to rise but is still at a historically low level. The arrival volume in April increased significantly, and the floating volume at sea surged. It is expected that large ships will arrive at ports in mid - to - late May, and the inventory may return to the normal range [4] 3.1.3 Cost and Profit - The entire industry is still in a loss state, and there are still expectations for production cuts. Special attention should be paid to the production reduction progress in Inner Mongolia and Ningxia. Coke's second - round price increase was blocked, and the coke price is expected to be weak. The electricity prices in the north and south production areas have decreased to varying degrees, and there is an expectation of a decrease in Ningxia's electricity price [4] 3.1.4 Market Review - In April, the silicon manganese futures price continued to decline, and the spot price followed the decline. As of April 28, 2025, the closing price of the silicon manganese 509 contract was 5804 yuan/ton, with a cumulative decline of 6.66% compared with the beginning of the month; the price range of Inner Mongolia 6517 was 5680 - 5900 yuan/ton, with a cumulative decrease of 220 yuan/ton [6] 3.2 Silicon Iron 3.2.1 Supply and Demand Analysis - Supply: In April, the production and operating rates decreased significantly. It is expected that the national output in April will be 430,000 - 440,000 tons. Since the end of March, news of factory production cuts and shutdowns has been continuously reported, and production area shutdowns and overhauls have gradually increased since mid - April [45] - Demand: With the repair of steel mill profits, blast furnaces have been actively restarted, and hot metal production has increased more than expected. In April, steel tenders progressed slowly, and most steel mills' tender prices decreased to varying degrees compared with the previous round. Non - steel demand remained stable, and downstream pre - holiday restocking was mainly based on demand - based procurement. The cumulative silicon iron export volume from January to March decreased significantly year - on - year [45] 3.2.2 Cost and Profit - The semi - coke market has been stable recently. The price of lump coal in the raw material end has declined, weakening the cost support for semi - coke. The overall operating rate of semi - coke enterprises is low, and they have entered the regular maintenance season, with the overall supply continuing to shrink. The price of small materials in Shaanxi has not changed significantly this month. The electricity price in Inner Mongolia was reduced by 0.015 yuan in mid - April, and there is an expectation of a decrease in Ningxia's electricity price [45] 3.2.3 Market Review - In April, the silicon iron futures price continued to decline, and the spot price followed the decline.

Report Industry Investment Rating No relevant information provided. Core Views Polyolefin Industry - LL: In May, maintenance increases and imports decrease. If the exemption of ethane imports weakens the expectation of supply reduction, attention should be paid to the demand situation after May. Under the situation of weak supply and demand, the inventory pressure is still large, and there is a possibility of decline in the long - term pattern [4]. - PP: In the second quarter, the peak maintenance season eases the supply pressure slightly, but the output is still high. The demand has bottom support but is gradually weakening. The long - term pattern is weak, and there is a downward risk [4]. Styrene Industry - The market price of pure benzene continues to decline. The raw material trend is weak, and the downstream styrene futures are also weak. The supply of pure benzene has returned, and there is no sign of improvement. The styrene market is weakly volatile, and there is supply pressure in May. In the medium term, due to the impact of tariffs, there is price pressure on styrene. The strategy is to participate in high - altitude operations, with the upper resistance line at 7300 [11]. Polyester Industry - PX: The short - term trading may be stronger, and the strategy is to focus on expanding the low - level spread of PX - SC. - PTA: The supply and demand drive becomes stronger, and the price support is relatively strong. The strategy is to wait and see before the festival, and treat TA9 - 1 as a short - term positive spread and a medium - term reverse spread. - Ethylene glycol: It is expected to fluctuate in May. The strategy is that EGO9 is expected to fluctuate between 4050 - 4300. - Short - fiber: The rebound space is limited, and it will be mainly adjusted by shock before the festival. The strategy is similar to PTA for one - side trading, and pay attention to the opportunity to expand the processing fee of PFO6 below 900. - Bottle chips: The output is expected to be high, and the relative price follows the raw material fluctuations. The strategy is similar to PTA for one - side trading, and the main contract processing fee is expected to fluctuate between 350 - 550 yuan/ton [16]. PVC and Caustic Soda Industry - Caustic soda: The short - term supply and demand improve marginally, but the long - term expectation is weak. It is recommended to wait and see before the festival, and mainly go short in the medium - term for the 09 contract. - PVC: The start - up rate increases slightly, and the social inventory continues to decline seasonally. The demand is average, and there are problems in exports. The short - term operation should be cautious, and the medium - and long - term strategy is to participate in high - altitude operations [24]. Urea Industry - The main problem is the poor connection between supply and demand under the background of high supply. The supply pressure is increasing. The demand shows structural differentiation. The main contract 2509 may have a small rebound after the festival. It is recommended to wait and see before the festival, and take a short - selling strategy on rallies after the festival if there is a small rebound and no obvious improvement in the fundamentals. The option strategy is to buy and expand the spread in the short - term [30][31]. Crude Oil Industry - The overnight oil price was weakly running, pressured by macro - pressure and supply - side easing expectations. If the consumption end fails to replenish stocks in May, the downward channel of the market may further open. It is recommended to wait and see before the festival. The volatility ranges are given as [59, 69] for WTI, [62, 72] for Brent, and [460, 520] for SC. The option strategy is to focus on increasing volatility [49].
