操作方面，在市场未给出明确变盘信号前，主要策略以持有等待为主。前期4月9日参与抄底和布局的朋 友，若手中品种未经历大幅上涨，仍处于低位，可中度仓位继续持有等待，只要仓位不过重就行。短线 方面，虽市场目前未出现向下变盘，仍处于向上震荡中，但近期涨幅较高的品种，如前期提示的君君方 向（提示后已回落）及抱团品种，已出现明显负反馈，要防范回调风险。昨天抱团里最高标品种已出现 跌停，涨幅较高且出现涨不动，如连续2 - 3天明显涨不动、冲高回落、大幅高开低走等情况的品种，一 定要注意风险，这类品种只要走弱，就无条件减仓走人。另外，可关注一些低位板块，如昨天启动的煤 炭、有色板块等，仍存在短线机会。 5月22日，和讯投顾高璐明称市场进入关键变盘节点，即将选择方向，昨夜美股大跳水，引发对今日市 场走势及调整风险的关注。先看消息面，其一，昨晚美债拍卖结果糟糕，长期美债成抛售重灾区，20年 期美债收益率日内冲高13个基点至5.123%，10年期国债收益率飙升至5.09%，还创近三个月新高至 4.6%，直接引发美股跳水、美元下跌。不过，这对我国影响相对较小，美债下跌反而可能推动人民币 汇率升值，助力市场向好，无需过度担忧。其二，昨 ...

1. Report Industry Investment Rating - No industry investment rating is provided in the report. 2. Core Viewpoints of the Report - The prices of most energy and chemical products are expected to fluctuate. Crude oil, fuel oil, asphalt, polyester, rubber, methanol, polyolefin, and polyvinyl chloride are all forecasted to have an oscillatory trend [1][3][5][6]. 3. Summary According to Relevant Catalogs 3.1 Research Views - **Crude Oil**: On Thursday, oil prices rose significantly. OPEC's oil production in April may have slightly decreased due to the US's attempt to curb oil flow, leading to reduced supply from Venezuela, Iraq, and Libya. The US's expanded sanctions have increased market concerns and caused oil prices to rebound. The oil market will continue to fluctuate [1]. - **Fuel Oil**: On Thursday, the main fuel oil contracts on the Shanghai Futures Exchange rose. Singapore and Fujeirah's fuel oil inventories decreased. The reduction in East - West arbitrage arrivals in May will support the low - sulfur market in the short term. High - sulfur fuel oil is also supported by the expected improvement in Middle Eastern summer power generation demand, but low raw material procurement demand will still pressure the market [3]. - **Asphalt**: On Thursday, the main asphalt contract on the Shanghai Futures Exchange fell. This week, the shipment volume of domestic asphalt enterprises decreased, while the capacity utilization rate of modified asphalt increased. With the improvement of processing profits, supply is expected to increase. The issuance of special bonds is expected to accelerate, and terminal demand is supported, but attention should be paid to the pressure brought by increased supply [3]. - **Polyester**: PTA, EG, and PX futures prices rose on Thursday. PTA's load decreased and then is expected to rise. The overall ethylene glycol start - up load increased. Some MEG devices restarted or plan to shut down. The production and sales of polyester yarn in the Yangtze River Delta are weak. The prices of PX and PTA will follow cost fluctuations, and ethylene glycol is relatively resistant to decline [5]. - **Rubber**: On Thursday, the main rubber contracts on the Shanghai Futures Exchange fell. The start - up loads of domestic tire enterprises' semi - steel and all - steel tires decreased. The rubber market fundamentals are weak, but the delayed rubber tapping in Thailand will support prices in the short term [6]. - **Methanol**: On Thursday, methanol prices showed certain trends. In May, domestic supply is expected to increase, while demand will remain relatively stable, and price support will weaken [6]. - **Polyolefin**: On Thursday, the average national price of polypropylene (PP) was reported, and the prices of polyethylene (PE) in different regions decreased. Supply is expected to decline due to refinery maintenance, but demand will enter the off - season, and the decline in inventory will slow down. Polyolefin prices are expected to fluctuate weakly [7]. - **Polyvinyl Chloride (PVC)**: On Thursday, PVC prices in East, North, and South China decreased. The real estate construction off - season will drag down the demand for PVC downstream products, and exports may decline. In May, the PVC market fundamentals are loose, and prices are expected to remain low and fluctuate [7]. 3.2 Daily Data Monitoring - The report provides the basis data of various energy and chemical products on May 8th and 9th, including spot prices, futures prices, basis, basis rate, and their changes and historical quantiles [8]. 3.3 Market News - OPEC's oil production in April may have slightly decreased, despite the relaxation of voluntary production cuts. The organization plans to accelerate production increases in May and June, but the impact of the US's restrictions on Iran and Venezuela remains uncertain. Kazakhstan has no plan to cut crude oil and condensate production in May [11]. 3.4 Chart Analysis - **Main Contract Prices**: The report presents the closing price charts of the main contracts of various energy and chemical products from 2021 to 2025, including crude oil, fuel oil, asphalt, LPG, PTA, ethylene glycol, etc. [13][14][17]. - **Main Contract Basis**: The basis charts of main contracts such as crude oil, fuel oil, and asphalt are provided, showing the basis trends over the years [28][32][33]. - **Inter - period Contract Spreads**: The report shows the spread charts of different contracts of fuel oil, asphalt, and other products, such as the spreads between 05 - 09 and 09 - 01 contracts of fuel oil [44][45][46]. - **Inter - variety Spreads**: The spread charts between different varieties are presented, including the spreads between domestic and foreign crude oil, B - W spreads of crude oil, and the spreads between fuel oil and asphalt [60][64][65]. - **Production Profits**: The production profit charts of ethylene - made ethylene glycol, PP, and LLDPE are provided [68][69][72]. 3.5 Team Member Introduction - The report introduces the members of the energy and chemical research team, including Zhong Meiyan, Du Bingqin, Di Yilin, and Peng Haibo, along with their positions, educational backgrounds, honors, and professional experiences [74][75][76].
