On May 21, Allegro MicroSystems rose 5.11% in regular trading, trading at $43.785/share, with trading volume of approximately $48.52 million.

On the news front, the semiconductor sector staged a broad-based rebound, with Advanced Micro Devices up 7.56%, Intel up 6.25%, Marvell Technology up 4.86%, Micron Technology up 4.29%, and NVIDIA up 1.68%, providing systematic uplift to individual stocks. Allegro MicroSystems had previously declined over 14% since May 12, pressured by consecutive Form 144 filings from a major shareholder signaling planned share sales on May 11, May 14, and May 18. The current bounce exhibits characteristics of an oversold technical recovery following the steep selloff. However, the most recent Form 144 filing on May 18 indicates that further selling pressure from the major shareholder may persist in the near term.
