Amphastar Pharmaceuticals, Novavax, and Organon Shares Skyrocket, What You Need To Know
A number of stocks jumped in the afternoon session after a softer-than-expected inflation report fueled hopes for interest rate cuts by the Federal Reserve. The January Consumer Price Index (CPI), a key measure of inflation, rose by 0.2%, which was less than economists had forecast, with the annual rate cooling to 2.4%. This encouraging data increased market expectations for the Fed to begin cutting interest rates as early as June. The news prompted a rally in Treasuries as their yields fell. While the market's reaction was initially described as a "bumpy ride" due to concerns in other sectors, the favorable inflation data ultimately helped calm Wall Street. Lower inflation is a key prerequisite for the central bank to ease its monetary policy, which is generally supportive of stock valuations.
