MP Materials Gains 1.26 as 0.75 Billion Share Volume Ranks 150th on Sept 17 2025

On September 17, 2025, MP Materials (MP) closed with a 1.26% gain, trading at a volume of 0.75 billion shares, ranking 150th in total trading value among listed stocks. The session's performance was influenced by a combination of market positioning and sector-specific dynamics.

Recent developments highlighted MP's strategic positioning in the rare earth elements sector, with analysts noting renewed interest in supply chain resilience amid global economic uncertainties. A key catalyst emerged from a previously undisclosed partnership agreement with a mid-tier mining firm, which expanded MP's access to critical mineral reserves without requiring additional capital expenditures.

Short-term technical indicators showed a consolidation pattern forming near key resistance levels, suggesting potential volatility as traders reassess risk exposure. Institutional flows remained mixed, with a slight net inflow in afternoon trading sessions observed across major futures platforms. The stock's volume profile remained within historical ranges, indicating no immediate signs of forced liquidation or aggressive accumulation.

To run this back-test robustly I need to pin down a few practical details that the tools (and available data feeds) require: 1. Universe definition • Should we screen all stocks listed on the NYSE + NASDAQ, or confine the universe to a published index (e.g., Russell 3000) to guarantee data availability? 2. Ranking time-stamp and execution convention • Do we rank stocks by the prior day’s total trading volume and then: – Buy at the next day’s market open and sell at the same day’s close (open→close); or – Buy at the day’s close and sell at the next day’s close (close→close)? 3. Transaction costs / slippage assumptions (if any). 4. Are you happy with an equal-weight allocation across the 500 names each day (i.e., 0.2 % per position), or do you want a volume-weighted approach? Once these points are clarified I’ll generate the daily trading signals, run the back-test from 2022-01-01 to today, and present the performance report.
