MP Materials Corp. (MP) Down 8.8% — Is It Time to Move On?
MP Materials Corp. (MP) spent the latest session under clear pressure, sliding 8.82% and losing $6.14 to finish at $63.44. The stock retreated sharply from the prior close of $69.58, extending a broader pattern of price weakness that has left shares well below their recent peak. Trading activity was heavy, with volume of 18.2 million shares, meaningfully above the 90-day average of about 12.7 million. That elevated turnover underscores the intensity of the latest move, as sellers gained the upper hand and the stock continued to lose ground.
From a longer-term perspective, MP is now trading far beneath its 52-week high of $100.25 set on Oct. 14, 2025, marking a substantial slide from peak levels. At the current price, the stock has surrendered a significant portion of its past year’s gains and remains much closer to the lower end of its $18.64–$100.25 range. Within the materials and industrials complex, several peers — including Air Products and Chemicals (APD), Albemarle (ALB), and Dow Inc. (DOW) — have also faced periods of volatility, but MP’s latest single-session drop stands out as particularly steep. Overall, the price action points to a stock under sustained pressure, with recent trading sessions reflecting mounting headwinds and a market that has been increasingly willing to mark the shares lower.
Why MP Materials Corp. Price is Moving Lower
Recent trading in MP Materials Corp. reflects mounting pressure as investors reassess the risk profile after a sharp multi-day swing. The stock’s 8.25% drop on Jan. 26, on volume materially above its 90-day average, points to active selling rather than routine noise. This weakness is occurring against a backdrop of ongoing losses, with EPS at -$0.71 and a deeply negative profit margin near -50%. Even though the company beat Q4 EPS expectations, revenue fell 14.9% year over year and declined another 6.7% sequentially to about $53.6 million, signaling contracting top-line momentum. Such deteriorating fundamentals are a key headwind for a name that has already delivered a 200%+ one-year price surge and is trading at a valuation that embeds high growth expectations despite negative earnings.
Caution is also warranted given the disconnect between bullish analyst commentary and the company’s current financial profile. The “Moderate Buy” consensus and price targets near $79, alongside models suggesting substantial undervaluation, are colliding with visible operational and profitability challenges. High-profile insider sales totaling roughly $62.8 million add another layer of concern, as they can be interpreted as reduced confidence in near-term upside. Sector enthusiasm around rare earth demand, EV adoption, and U.S. supply-chain reshoring has driven aggressive rerating across materials peers like Air Products and Chemicals, Albemarle, and Dow. But for MP, investors appear to be rotating from story-driven optimism toward scrutiny of execution risk, sustained losses, and the possibility that expectations and valuation have outpaced the company’s current earnings power.
What is the MP Materials Corp. Rating - Should I Sell?
Weiss Ratings assigns MP Materials Corp. (MP) a D rating. Current recommendation is Sell. The stock was downgraded on 8/11/2025, signaling a weaker overall risk/reward profile than many alternatives in the Materials space. A D rating means the company has underperformed on a risk-adjusted basis and faces significant challenges that, at this stage, outweigh its potential upside for investors.
Beneath the headline rating, several sub-indices paint a cautious picture. The Very Weak Growth Index captures MP’s deteriorating fundamentals, including revenue declining 14.90% and a profit margin deep in negative territory at -50.54%. The Very Weak Efficiency Index further indicates that management is generating poor returns on the capital it employs, consistent with a deeply negative forward P/E ratio of -98.46. These metrics show that, despite any long-term thematic appeal of rare earths, the current business performance is failing to translate into shareholder value.
Risk factors also remain a concern. The Weak Volatility Index signals an unfavorable balance between upside potential and downside risk, while the Fair Total Return Index shows that past stock performance has not adequately compensated investors for that risk profile. The one bright spot is the Excellent Solvency Index, which indicates a solid balance sheet. However, strong solvency alone has not been enough to offset operational weakness and sustained losses.
Within its sector, MP’s D rating is in line with other challenged names such as Air Products and Chemicals, Inc. (APD, D+), Albemarle Corporation (ALB, D+), and Dow Inc. (DOW, D+). Even against these relatively weak peers, MP does not stand out as a superior option, reinforcing the need for caution.
About MP Materials Corp.
MP Materials Corp. is a materials company focused on rare earth extraction and processing, operating in a niche that remains structurally concentrated and difficult to access. Through its Materials segment, the company owns and operates the Mountain Pass Rare Earth Mine and Processing facility in San Bernardino County, California, one of the few rare earth production sites in the Western Hemisphere. Its activities are centered on mining, separating and processing rare earth materials that are used in high-performance magnets and other advanced applications. The business model relies on a single major production hub, creating operational dependence on one primary asset and its associated regulatory, environmental and technical risks.
The Magnetics segment extends the company’s role further down the rare earths value chain, producing magnetic precursor products intended for use in permanent magnets. This vertical integration strategy aims to move MP Materials from being only a raw materials producer to a processor and value-added supplier. However, the company operates in a highly specialized, capital-intensive corner of the materials industry, where processing complexity, stringent environmental standards and technological execution risk are all elevated. Headquartered in Las Vegas, Nevada, and founded in 2017, MP Materials is relatively young compared with many diversified materials peers, with a shorter operating track record and less geographic and asset diversification. Its concentration in rare earth materials, and reliance on complex processing operations, leaves the company more exposed to industry-specific challenges than broader-based materials companies.
Investor Outlook
With MP Materials Corp. (MP) carrying a D (Sell) Weiss Rating, investors may want to exercise caution and closely monitor how its risk/reward profile evolves from here. Key areas to watch include whether sector dynamics in Materials improve, if operational execution strengthens enough to support a higher overall rating, and how the stock behaves around recent support and resistance levels.
