The investment firm increased its target to $1,250 from $1,050 while keeping an 'Overweight' rating. This decision was based on supply chain research suggesting Monolithic Power was positioned to capture about 70% of the market for components on NVIDIA's new Vera Rubin platform. The positive outlook from the analyst reflected strong confidence in the semiconductor company's future performance.
