Another View: Looking at Market Comparisons

While analysts project major upside, market-based ratios tell a more cautious story. MP’s price-to-sales ratio sits at an eye-popping 44.3 times, significantly higher than both peers (0.7x) and the US mining industry average (2.1x). If the stock moves closer to its fair ratio of 2.5x, the current price may carry hefty valuation risk. Which side of the story will win out?
