Prudential Group's portfolio expert Amanda Ng has highlighted upstream supply chain components as the next significant opportunity for AI-related investments. In a recent report, Ng emphasized the growing importance of advanced packaging, semiconductor substrates, and high-end printed circuit boards (PCBs) in the AI sector. Although these components represent a small fraction of the total materials cost for AI, they are poised to become critical bottlenecks. Ng noted that even minor price increases in these areas could substantially enhance manufacturers' profitability while remaining cost-effective for consumers.
