AI's Boost to Storage Demand
The surge in demand for high-bandwidth memory (HBM) during AI training and inference processes has created structural opportunities in the storage chip industry. Breakthroughs by storage giants like SK Hynix and Micron in HBM4 technology have led to rating upgrades by multiple investment banks. Wall Street analysts widely believe that the HBM market will enter a super cycle in the second half of 2026, with related companies poised to exceed performance expectations.
Regional Industry New Opportunities
In addition to technology-driven growth, regional policy benefits and industrial chain restructuring have brought new growth opportunities for US semiconductor companies. Southeast Asia, with its policy support and cost advantages, has become an important destination for semiconductor industry relocation, providing US semiconductor companies with opportunities for regional diversified expansion.
Policy Benefits in Southeast Asia
Since 2026, Southeast Asian countries have successively introduced semiconductor industry support policies. Malaysia launched Semiconductor Strategy 2.0, planning to invest over $10 billion to develop advanced packaging industries; Thailand established a 5 billion baht special fund to support advanced packaging technology R&D; Singapore initiated a 3 billion Singapore dollar advanced packaging flagship program to build a regional semiconductor innovation center. These policy measures provide strong support for US semiconductor companies' expansion in Southeast Asia.
RCEP's Impact on Semiconductor Industry Chain Restructuring
The implementation of the Regional Comprehensive Economic Partnership (RCEP) has accelerated the integration and restructuring of the Asian semiconductor industry chain. Under the RCEP framework, tariff barriers for various links in the regional semiconductor industry chain have been significantly reduced, and trade facilitation has markedly improved. This change enables US semiconductor companies to more efficiently integrate resources in the Asia-Pacific region, optimize global supply chain layouts, reduce production costs, and enhance market competitiveness.
Comparison of Semiconductor Policies Across Countries
In the Asia-Pacific region, semiconductor policies show differentiated characteristics. Vietnam focuses on automotive-grade chip packaging and testing, introducing special policies to encourage foreign investment; Malaysia concentrates on advanced packaging and testing segments, building a regional packaging and testing center; Singapore is committed to developing semiconductor design and R&D, constructing a high-end industry chain. This differentiated development landscape provides US semiconductor companies with diversified regional layout options, allowing them to choose the most suitable development path based on their business characteristics.
Institutional Rating Analysis
In the second half of 2026, multiple international investment banks have released the latest rating reports for the US semiconductor sector, showing an overall optimistic outlook. According to aggregated data, over 70% of institutions have given "buy" ratings to the US semiconductor sector, with average target prices showing over 20% upside from current stock prices.
Rating Trends for US Semiconductor Sector by Major Investment Banks
Top investment banks like Goldman Sachs, Morgan Stanley, and UBS have all upgraded their ratings for the US semiconductor sector. Goldman Sachs believes that AI demand will continue to drive semiconductor industry growth, projecting a 15%-20% increase for the US semiconductor sector in the second half of 2026; Morgan Stanley emphasizes that regional policy benefits will accelerate semiconductor industry chain restructuring, bringing valuation enhancement opportunities for related companies; UBS is optimistic about the growth potential of HBM and advanced packaging sectors, believing these two sub-sectors will become the main drivers of performance growth.
Rating Changes for Leading Enterprises
Among leading US semiconductor companies, ratings for NVIDIA, AMD, and Intel have generally been upgraded. Especially NVIDIA, with its absolute advantage in AI computing, has become the most favored institutional target. Six major investment banks have collectively given NVIDIA "buy" ratings, with the highest target price raised to $900. AMD, with its strong performance of MI series GPUs in the AI market, has received rating upgrades from multiple investment banks, with target prices generally above $200.
Rating Outlook for Emerging Enterprises
In addition to traditional giants, some emerging companies in the US semiconductor sector have also gained institutional attention. Particularly in the advanced packaging sector, ratings for packaging and testing giants like Amkor and ASE have been continuously upgraded. Amkor Technology, with its active expansion in Southeast Asia and leading advantages in advanced packaging technology, has become a key focus for institutions. Multiple investment banks have given Amkor Technology "buy" ratings, believing it will benefit the most from the growth in AI-driven packaging and testing demand.
Investment Strategy Recommendations
Based on an in-depth analysis of the US semiconductor sector, we propose the following investment strategy recommendations to help investors seize investment opportunities in the semiconductor industry in the second half of 2026.
Long-term Investment Value
From a long-term perspective, the continuous evolution of AI technology will provide sustained growth momentum for the semiconductor industry. Investors should focus on companies with core competitiveness in AI chip design, advanced packaging, high-bandwidth memory, and other fields. Especially AI chip leaders like NVIDIA and AMD, and leading enterprises in advanced packaging like Amkor and ASE, are expected to benefit from long-term growth.
