MULL ETF (MULL) is trading 5.2% up today as the semiconductor sector extends its AI-driven advance following Samsung’s industry-first HBM4E sample shipments.

  • Samsung’s announcement is boosting high-bandwidth memory (HBM) and AI-chip names, reinforcing the sector's position as a key market leadership group.
  • Broader technology sentiment is further supported by slightly cooler PCE inflation data and renewed investor risk appetite across major indices.
  • As a leveraged instrument, MULL is amplifying the upside move seen in AI-related chip stocks and the wider information technology sector.
