MP Materials Soars 8.37% on $4.21 Billion Surge, Ranks 26th in Active Trading

MP Materials (MP) surged 8.37% on October 10, 2025, with a trading volume of $4.21 billion, marking a 127.02% increase from the previous day and ranking 26th among the most actively traded stocks. The rally followed renewed investor focus on critical mineral supply chains amid global economic policy shifts.

Analysts noted that recent regulatory developments in rare earth processing technologies and strategic partnerships with U.S. energy firms contributed to the stock's momentum. Market participants highlighted the company's positioning in the green energy transition as a key driver, with institutional flows favoring long positions ahead of quarterly earnings releases.

Technical indicators showed sustained buying pressure through the session, with the stock closing above key resistance levels. Short-term traders emphasized the importance of maintaining positive momentum to solidify gains, while longer-term investors remain cautious about macroeconomic risks ahead of central bank policy decisions.

To conduct an accurate back-test, several parameters require clarification: the market universe (U.S.-listed stocks only or broader scope), re-balancing conventions (close-to-close vs. open-to-close), transaction cost assumptions (zero costs or 2 bps per side), and benchmark comparisons (e.g., SPX). Implementation details will determine the methodology for testing performance from January 3, 2022, to the present.
