Another View: Price-to-Earnings Tells a Different Story

While the narrative suggests Supernus Pharmaceuticals is undervalued, the price-to-earnings ratio paints a more cautious picture. Trading at 41.7 times earnings, SUPN looks expensive compared to both its peers (24.8x) and the US pharmaceuticals industry average (18.3x). The fair ratio the market could move towards is 26.4x, which signals a potential valuation risk if expectations reset. So, does the optimism outweigh the pricing risk?
