10 Hottest Mid-Cap Stocks So Far in 2025

6. MP Materials Corp (NYSE:MP)
  • YTD Performance: 27.8%

MP Materials (NYSE:MP) is a rare earth minerals company and the company operates in the Mountain Pass mine in California (the only integrated rare earth mining and processing site in North America), so it’s got a unique place in the American supply chain.

They reported a net loss for Q2 2024, primarily due to reduced revenue from rare earth concentrates; apparently, they’ve been trying to improve profitability but have faced “challenges” doing so.

Another flashpoint: China’s ban on exporting certain minerals to the United States stirred up extra attention around MP Materials. The company has insisted it’s heavily investing in processing and refining capabilities, presumably so that once demand creeps back up, it can boost future returns.

In my opinion, it is still worth buying. MP stock is undergoing a recovery rally and the stock remains down some 62% from its peak in 2022. If demand starts to bounce back more, so will the stock.
