On June 26, Monolithic Power Systems fell 6.49% in regular trading, trading at $1,315.61/share, with turnover of $222 million.

On the news front, the semiconductor sector experienced broad-based selling pressure. Micron Technology fell 5.93%, Intel dropped 4.23%, Advanced Micro Devices declined 3.91%, Broadcom slid 2.97%, and NVIDIA fell 1.26%, with sector-wide linkage effects significantly dragging on the stock.

The stock had previously surged after NVIDIA announced its next-generation 800V power architecture partner list, with MPS named among officially endorsed suppliers. Combined with expectations of power management IC price increases and plans to expand pricing adjustments in July, the stock experienced a rapid short-term rally. However, following multiple rounds of profit-taking in recent sessions, the renewed sector weakness has compounded technical selling pressure, deepening the pullback.
