MagnaChip Semiconductor is trading 5.04% higher at $3.96 after closing September 28, 2026, at $3.79; no new company-specific announcement explaining the after-hours move was identified.

  • Shares had already gained 14.85% during the regular session.
  • Navitas’s $5 million strategic investment was announced September 21 and linked to an earlier share-price surge; it is context, not a confirmed fresh catalyst. Broader markets were risk-off, which does not explain the stock’s rise.
