It considers factors such as supply - demand relationships, plant maintenance, trade policies, and cost changes to evaluate the short - and medium - term trends of each commodity. 3. Summary by Commodity PX, PTA, MEG - **PX**: Short - term rebound, medium - term pressure. Low processing fees lead to more overseas plant maintenance, and Asian PX operating rate drops to 68.6%. May is a de - stocking period, and new plants are expected to be put into operation in June, with processing fees likely to expand. Strategy: long PX short SC [10] - **PTA**: Short - term rebound, medium - term pressure. Sino - US tariff easing improves terminal demand expectations, and polyester sales improve. However, PTA and PX plant maintenance is concentrated, and the basis and spread are at a high level. Strategy: long PTA short MEG, avoid chasing the basis and spread [11] - **MEG**: Long PTA short MEG. The number of warehouse receipts is small, and there may be a positive spread arbitrage in the delivery month.

The demand for synthetic rubber has increased, and the inventory is at a high level year - on - year. The current fundamentals have a neutral impact on synthetic rubber [17][18][20] Asphalt - De - stocking continues, and crude oil prices decline slightly. The weekly production of domestic asphalt decreased, and both factory and social inventories decreased. The trend is neutral [21][30][31] LLDPE - Short - term oscillation, long - term pressure. Trade wars and new capacity additions bring supply - demand imbalances, and the demand for downstream products is weak. Strategy: bearish on polyethylene profit [32][33][34] PP - Prices oscillate, and trading volume is average. The increase in PP futures has a limited impact on the spot market, and downstream pre - holiday stocking has ended. The trend is neutral [38][39] 烧碱 - The medium - term trend is weak. Trade wars and seasonal factors affect demand, and the supply side has high operating rates. Strategy: short 06 and 07 contracts, 6 - 9 reverse spread [41][43][44] Paper Pulp - It is expected to oscillate weakly. The price of paper pulp futures decreased, and the market is divided.

Pay attention to the sustainability of the improvement. The inventory of urea enterprises increased, and the futures price rebounded after the spot price stabilized [62][63][64] Styrene - Weakly oscillate. The supply of pure benzene increases, and the demand decreases. The downstream demand for styrene has resilience, but the terminal default risk is increasing [65][66][69] Soda Ash - The spot market changes little. The operation of soda ash plants is stable, and downstream demand is stable. The market is expected to be slightly bullish in the short term [70][72] LPG - As the delivery approaches, the structure continues to strengthen. The prices of LPG futures increased, and the operating rates of PDH, MTBE, and alkylation decreased. The trend is neutral [74][80][81] PVC - Weakly oscillate.

Low - sulfur fuel oil is stronger than high - sulfur fuel oil in the short term, and the spread between high - and low - sulfur fuel oils rebounds slightly [87] Short - fiber and Bottle - chip - Short - fiber and bottle - chip are expected to rebound following raw materials. For bottle - chip, short the processing fees on rallies. The trading volume of short - fiber futures increased, and the sales of polyester bottle - chip plants improved [89][90]

Core Viewpoint - The recent rapid decline in the US stock market, characterized as one of the fastest in history, is primarily driven by uncertainties surrounding Trump's tariff policies, weak economic data, and heightened market panic. The market has lost over $4 trillion in value, erasing gains made since Trump's election in November 2024 [2][3][24]. Group 1: Causes of the Market Decline - The S&P 500 index officially dropped over 10% as of March 13, marking a significant adjustment within just 16 trading days, one of the fastest declines recorded [7][24]. - Historical patterns indicate that extreme downturns are often triggered by policy shocks or systemic risks, with the current situation resembling the market turbulence seen during the 2018 trade war [24]. - Key factors contributing to the current market turmoil include: 1. Trump's frequent references to tariff policies, which have increased corporate costs and heightened trade uncertainties, threatening economic growth [8][9]. 2. Weak economic indicators since February, showing a slowdown in growth, rising inflation pressures, and declining consumer confidence [8][9]. 3. Deteriorating market sentiment, with the CNN Fear & Greed Index dropping to 21, indicating extreme fear among investors [9]. Group 2: Historical Context and Comparisons - Since 1950, there have been 40 instances where the S&P 500 index has corrected by more than 10%, with only six of these occurring within 20 days, highlighting the severity of the current situation [7][8]. - The article draws parallels between the current market conditions and previous downturns, such as the 2008 financial crisis and the 2020 COVID-19 pandemic, which were also marked by significant policy and economic uncertainties [8][9]. Group 3: Strategies for Navigating Market Volatility - The RockFlow research team suggests several strategies for investors to navigate the current volatility: 1. Implementing long-short strategies using inverse ETFs to capitalize on market reversals [17]. 2. Utilizing volatility strategies to take advantage of increased market fluctuations, particularly through VIX-related instruments [19]. 3. Employing "small bear insurance" by purchasing put options to hedge against short-term declines while maintaining long-term positions [21][23]. 4. Utilizing "bottom-fishing" tools to identify and invest in undervalued assets during market downturns [24].
