Sigma Lithium Corp. Hits Day High with 28.88% Surge in Stock Price

Sigma Lithium Corp. has experienced a significant surge in its stock price, gaining 28.88% on February 25, 2026. The stock reached an intraday high of CAD 23.00, marking a notable performance against the backdrop of the S&P/TSX 60, which only saw a modest increase of 0.51% on the same day. Over the past week, Sigma Lithium has shown a robust performance with a 22.47% increase, while its monthly gain stands at 11.72%. Year-to-date, the stock has risen by 24.1%, outperforming the S&P/TSX 60's 5.16% gain. However, the company's longer-term performance reveals a more complex picture, with a 3-year decline of 53.11%, despite a remarkable 322.64% increase over the past five years. Financially, Sigma Lithium faces challenges, including a high debt-equity ratio of 191.36% and a significant drop in net sales, which fell by 28.14% to CAD 39.32 million. The company’s return on equity is currently at -40.27%, indicating ongoing financial pressures. As Sigma Lithium navigates these dynamics, its recent stock activity highlights the volatility and potential risks within the minerals and mining sector.
