🟢 Allegro Microsystems is trading 5.1% up in after-hours trading

Allegro Microsystems is trading 5.07% up after hours at $34.00, but its immediate catalyst remains unclear.

• The move compares with the regular-session close of $32.36.
• No clearly verified Allegro-specific announcement explaining the after-hours jump surfaced in available reporting.
• Semiconductor sentiment was weak amid inflation and interest-rate concerns. Reports cited a broad chip sell-off, including pressure on chip stocks despite TSMC’s strong results; that sector weakness does not explain Allegro’s opposite-direction move.
