Therefore, it is judged to be a fluctuating trend, with an overall bearish operation, indicating a high-level correction.

Petroleum coke 60-day, 3-month, and 1-year cycle prices are all in the 5th tier (high position) out of 5 tiers, with limited room for further increases and a higher risk of a high-level correction.
VI. Upstream and Downstream References
Upstream: The core upstream commodity for petroleum coke is Brent crude oil. Currently, the 1-year price cycle of Brent crude oil is in a mid-to-high range, providing strong support to the cost side of petroleum coke in China.
Downstream: The downstream sectors of petroleum coke cover anhydrous aluminum chloride, silicon carbide, steel, glass, and graphite electrodes. Currently, the 1-year cycle price of glass is at a low level, and the demand side's support for petroleum coke is generally moderate.
