In early trading on Friday, shares of the U.S. coal and mineral extraction company Ramaco Resources Inc. (METC) fell 7.8%. Despite Raymond James assigning a "Buy" rating to the stock, this did not prevent its decline. Raymond James cited the upgrade as based on the company's potential in the U.S. rare earth economy, predicting that Ramaco will be well-positioned to benefit from efforts to build domestic production capacities for critical minerals in the U.S.
