Report Investment Rating - Not provided in the document Core Viewpoints - This week, the sentiment for going long cooled down, the number of profit - taking orders increased significantly, and lithium prices declined at an accelerated pace. The total open interest of lithium carbonate contracts decreased by 15.9% this week, reaching a new low since late October. The expectation of fundamental improvement in lithium carbonate remains unchanged. Recently, upstream maintenance and increased demand for battery exports have led to continued destocking of domestic lithium carbonate. However, the sustainability of supply - side contraction in the future is uncertain, and concerns about the negative feedback caused by rising terminal costs are increasing, so there is significant pressure on the upside of lithium prices. Against the background of low downstream inventories, the bargaining power for pre - holiday raw material procurement is low. After the release of price risks, there may be support at the short - term bottom. Given the large fluctuations in the commodity market recently, and the exchange adhering to the principle of strict supervision, it is recommended to observe cautiously or try with a light position [12] Summary by Directory 1. Weekly Assessment and Strategy Recommendation - **Weekly Highlights** - **Futures and Spot Market**: On January 30, the evening quotation of the Mysteel MMLC lithium carbonate spot index was 155,107 yuan, a weekly decrease of 5.62%.

On the same day, the closing price of LC2605 on the Guangzhou Futures Exchange was 148,200 yuan, a weekly decrease of 18.36% [12] - **Supply**: Lithium salt plants arranged maintenance in the off - season. On January 29, SMM reported the weekly output of domestic lithium carbonate at 21,569 tons, a month - on - month decrease of 2.9%. The estimated domestic lithium carbonate output in January 2026 was 97,900 tons, a month - on - month decrease of 1.3% and a year - on - year increase of 56.7% [12] - **Demand**: The Passenger Car Association estimated that the domestic retail sales of new energy vehicles in January would be around 800,000, with a penetration rate of about 44.4%. The first quarter is a critical window period for "grabbing exports" of batteries. The off - season demand is expected to increase, and the decline in material production scheduling is narrower than previously expected [12] - **Inventory**: On January 29, the weekly inventory of domestic lithium carbonate was reported at 107,482 tons, a month - on - month decrease of 1,414 tons (- 1.3%). The inventory days of lithium carbonate were about 28.5 days. On January 30, the registered warehouse receipts of lithium carbonate on the Guangzhou Futures Exchange were 30,631 tons, a weekly increase of 8.8% [12] - **Cost**: The sentiment of price - holding at the ore end is relatively strong. On January 30, the SMM quoted the price of imported Australian SC6 lithium concentrate at 2,050 - 2,300 US dollars per ton, with a weekly increase of 4.4%. Observe the sustainability of cost support at the smelting end [12] 2. Futures and Spot Market - On January 30, the evening quotation of the Mysteel MMLC lithium carbonate spot index was 155,107 yuan, a weekly decrease of 5.62%.

Report Industry Investment Rating No relevant content provided. Core Viewpoints - This week, the market sentiment fluctuated significantly, with lithium carbonate rising first and then falling. Affected by the adjustment of the battery export tax - rebate policy, the lithium price broke through the 170,000 - yuan mark at the beginning of the week. However, the sentiment in the commodity market weakened in the middle of the week, with more profit - taking orders from lithium carbonate bulls, and it closed at the daily limit down on Friday, with the total open interest decreasing by 17.5% during the week. The expectation of fundamental improvement has been fully traded. If the increase in lithium price is transmitted to the end - users, the increase in battery cost will suppress some energy - storage demand, and the current price still has a certain emotional premium. Due to the large price fluctuations of lithium carbonate recently and many disturbances from the industrial and macro aspects, it is recommended to wait and see or try with a light position. Pay attention to the market atmosphere, demand policies, downstream acceptance willingness, and changes in open interest on the trading board [12]. Summary by Directory 1.

The sales of new - energy vehicles accounted for 52.3% of the total sales of new vehicles. In 2025, the production and sales of domestic new - energy vehicles reached 16.626 million and 11.649 million respectively, with year - on - year increases of 29% and 28.2% respectively. The sales of new - energy vehicles accounted for 47.9% of the total sales of new vehicles, 7 percentage points higher than the previous year. According to the China Automotive Power Battery Industry Innovation Alliance, in December, the combined output of power and energy - storage batteries in China was 201.7 GWh, a month - on - month increase of 14.4% and a year - on - year increase of 62.1%. From January to December, the cumulative output of power and energy - storage batteries in China was 1,755.6 GWh, a cumulative year - on - year increase of 60.1%. The first quarter is a critical window period for "grabbing exports" of batteries, and the demand in the off - season is expected to increase. The decline in material production scheduling is narrower than previously expected [12]. - **Inventory**: On January 15, the weekly inventory of domestic lithium carbonate was reported at 109,679 tons, a month - on - month decrease of 263 tons (- 0.2%). The inventory days of lithium carbonate were about 28 days. On January 16, the registered warehouse receipts of lithium carbonate on the GZFE were 27,458 tons, a weekly increase of 8.3% [12]. - **Cost**: The change in lithium salt prices is transmitted upstream. On January 16, the quotation of SMM Australian imported SC6 lithium concentrate was 2,070 - 2,100 US dollars per ton, with a weekly increase of 6.92%. As the lithium price falls, pay attention to the changes in the willingness of mining enterprises to support prices and release goods [12]. 2. Periodic and Spot Market - On January 16, the MMLC lithium carbonate spot index closed at 148,681 yuan in the evening session, with a weekly increase of 6.86%.
