MP Materials Shares Fall as U.S.-China Summit Thaw Erodes Rare-Earth Premium
MP Materials shares fell about 5% to $51.85 as hopes for a U.S.-China thaw after a potential Trump-Xi summit weighed on the scarcity premium behind domestic rare-earth valuations. USA Rare Earth dropped 4% and the VanEck rare-earth ETF fell about 5%, suggesting sector-wide selling tied to the macro setup rather than company-specific fundamentals.
