The lithium carbonate warehouse receipts were 34,154 lots, a decrease of 825 lots from the previous trading day [2] - The lithium carbonate market showed a gap - down and then a rebound, with wide - range fluctuations during the session and a short - covering rally at the end of the session [2] Group 2: Spot Market - On May 27, 2025, the price of battery - grade lithium carbonate was reported at 60,800 - 63,200 yuan/ton, down 500 yuan/ton from the previous trading day, and the price of industrial - grade lithium carbonate was reported at 59,900 - 60,900 yuan/ton, also down 500 yuan/ton from the previous trading day. The center of the spot transaction price of lithium carbonate continued to move down [3] - The supply - demand of the lithium carbonate market remained in an oversupply state, and there was no strong support for price increases. The demand side was stable with limited incremental demand, while the supply side had a significant incremental expectation as the non - integrated lithium salt plants got the opportunity to hedge and resume production with the slight rebound of the futures. Also, the cost support was weakening due to the continuous decline of lithium ore prices, further suppressing the lithium carbonate price [3] Group 3: Strategy - Fundamentally, the situation was weak, but the open interest of the 07 contract was high, and subsequent position reduction might cause large fluctuations. Short - term trading needed to pay attention to risks [4] - Unilateral strategy: Sell on rallies for hedging [4] - Option strategy: Sell out - of - the - money call options or use bear spread options [4] Group 4: Core View - The lithium carbonate spot was weak, and attention should be paid to the impact of futures position changes on the short - term market [1]
