Sigma Lithium Corp

Major lithium producers Albemarle and SQM declined in New York trading as Chinese spot prices for the battery metal showed significant volatility, with traders focused on upcoming policy cues and corporate results.

Albemarle shares dropped sharply after idling its Kemerton lithium processing unit in Australia. China's battery-grade lithium carbonate prices rose slightly, but spot trading remained sluggish.

Sigma Healthcare shares declined nearly 1% in Monday trading as investors await the company's half-year financial report due February 26, focusing on margin performance and cost management.
