The price trend is clearly downward. Reason: The changes in the 5-day, 10-day, and 20-day moving average differences from yesterday are all negative, which meets the criteria for a clear downward trend according to the moving average difference method; at the same time, on August 20th, companies such as Shandong Tianhong Chemical and Zibo Xintai Petrochemical significantly reduced their petroleum coke quotations, with only a few companies raising their prices. The overall market is weak, further supporting the downward trend.
IV. Positional Spatial Reference
Petroleum coke prices are currently at a medium-high level within a 1-year cycle, with limited room for further increases; under the current clear downward trend, attention should be paid to the demand from downstream industries such as anhydrous aluminum chloride and carbon electrodes in China, to assess the potential for further declines.
