On May 26, Monolithic Power Systems rose 3.12% in pre-market trading, trading at $1,634.79/share, with trading volume of approximately $1.18 million. The move was driven by broader semiconductor sector strength combined with continued momentum from the power management IC price hike cycle.

On the news front, a wave of price increases is spreading across the power management IC sector. Major manufacturers including Texas Instruments, NXP, MPS, and MediaTek subsidiary Richtek are planning to raise product prices from June through July. MPS issued a price increase notice in March and plans to further expand the scope of adjustments in July, with the industry's second-half earnings outlook improving. The price hikes are primarily driven by rising costs in wafer foundry and packaging/testing segments rather than end-market demand strength.

Fundamentally, the company's first-quarter adjusted EPS of $5.10 exceeded expectations of $4.89, while revenue of $804 million grew 26.24% year-over-year, supporting the stock's continued recovery from its prior pullback. Within the semiconductor sector, Micron Technology rose 6.09%, Advanced Micro Devices rose 2.89%, Qualcomm rose 2.24%, Intel rose 1.47%, and NVIDIA rose 1.27%.
