JPMorgan's analyst rating for SINOPEC CORP is slightly negative due to the recent increase in domestic gasoline and diesel prices, which is lower than expected. This will lead to higher crude oil costs for SINOPEC in the short term, as the company refines a significant amount of seaborne crude oil. Consequently, JPMorgan has lowered its 2026 net profit forecast for SINOPEC by 28%, while slightly increasing the 2027 forecast, resulting in a reduction of target prices for the company's shares.
