On July 12th, Guolonghui reported that Citigroup's research report pointed out that Chinalco predicted a net profit of between 6.5 billion and 7.3 billion yuan in the first half of this year, a year-on-year increase of 90% to 114%, reaching the bank's full-year forecast of 72% to 81%, and the market's general expectation of 71% to 80%, exceeding expectations. The bank expects that Chinalco's regular net profit in the first half of the year will reach 6.4 billion to 7.2 billion yuan, a year-on-year increase of 122% to 150%. The net profit in the second quarter is expected to increase by 166% to 216% year-on-year, reaching 4.3 billion to 5.1 billion yuan, and the quarterly growth rate is expected to be 91% to 127%. Citigroup believes that the significant growth in Chinalco's profit in the first half of the year is mainly due to the average selling price of aluminum and alumina during the period and the decrease in production costs. It is expected that the profit margin of its aluminum smelting business may continue to remain at a high level in the long term. It continues to list Chinalco as the preferred mainland resource stock and gives a target price of HKD 7.88, rating it as a "buy."
