Biotech stocks have been on fire in the past few weeks. They are recovering from the terrible performance the sector had over the last two year. The euphoria stemmed from the belief that pharmaceutical companies would continue to pay massive premiums for biotech firms because their blockbuster drugs had gone off patent.

This rally is being dampened by the Federal Trade Commission's efforts to stop Amgen's acquisition Horizon Therapeutics. The SPDR S&P Biotech ETF was down 3.4% Tuesday morning. Horizon fell 18%. Seagen, which sold itself to Pfizer in March for $43 billion, fell 6%.
