Why Monolithic Power Systems (MPWR) Stock Is Nosediving
Shares of power management chips maker Monolithic Power Systems (NASDAQ:MPWR) fell 6.3% in the afternoon session after stocks pulled back (Nasdaq -1.5%, S&P 500 -1.2%) amid fresh concerns about trade tariffs. The pullback followed comments from President Trump clarifying the scope of his administration's 25% tariffs on Venezuela. He noted that it would apply to any country that does business with Venezuela. For example, 25% is on top of the already-in-place 20% tariff on China because China imports oil from Venezuela, which could translate to a 45% tariff on some Chinese goods. This announcement could significantly raise the operating costs for affected companies and institutions.
