Monolithic Power Systems, Inc. (MPWR) closed at $1,478.75 on November 12, 2026, gaining 8.99% in the latest 24-hour session. The move pushed the stock's market capitalization to $66.21 billion.
The single-day advance built on broader momentum that has developed over recent weeks. MPWR has risen 17.25% over the past seven days and 12.10% over the trailing 30-day period, reflecting sustained buying pressure in the shares.
The consecutive gains across multiple timeframes mark a notable stretch of performance for the semiconductor company. The 30-day and 7-day figures suggest the latest session's jump was part of an accelerating trend rather than an isolated move.
As of the November 12 close, MPWR's cumulative gains across the measured periods position the stock among the stronger performers in its category over the near-term window covered by the available data.
