Lithium Americas Corp. (LAC) stock surged 8.19% in intraday trading, as rare earth stocks continue to gain momentum amidst rising trade tensions with China and increased U.S. government support for the industry. The significant uptick in LAC's share price comes as investors show renewed interest in companies critical to securing independent supply chains for rare earth materials.

The rally in LAC's stock price appears to be driven by multiple factors. Firstly, China's recent imposition of additional export restrictions on rare earth elements has prompted the U.S. and other countries to seek alternative sources, benefiting companies like Lithium Americas. Additionally, the Trump administration's past investments in rare earth element producers, including LAC, have put these stocks in the spotlight as potential beneficiaries of the current geopolitical climate.

Adding fuel to the fire, unusually high options activity was detected in Lithium Americas stock. Market data revealed 55,981 calls trading, which is twice the expected volume. This surge in bullish options flow was accompanied by a significant increase in implied volatility, jumping almost 17 points to 150.9. This options activity suggests that traders are positioning themselves for potential further upside in LAC's stock price, contributing to the day's impressive gains.
