This trend is changing the valuation logic of semiconductor companies and injecting new growth momentum into the US semiconductor sector.

Goldman Sachs emphasized in its latest research report: 'The Southeast Asia region, especially Vietnam, Malaysia, and Thailand, is becoming a hotbed for semiconductor capacity expansion. These countries not only provide tax incentives and land support but also reduce cross-border investment barriers through regional trade agreements such as RCEP. For US semiconductor companies, Southeast Asia capacity expansion can not only reduce production costs but also avoid trade friction risks, providing a solid foundation for long-term growth.'

Specifically, the capacity expansion plans of packaging and testing companies such as Amkor Technology (AMKR) and ASE Holding (ASX) in Southeast Asia have received positive evaluations from multiple investment banks. Citigroup upgraded these companies' ratings to 'Buy', believing that Southeast Asia capacity expansion will become the main driver of their performance growth in the next 2-3 years. Meanwhile, the expansion of Intel's (INTC) and Samsung Electronics' (SSNLF) manufacturing bases in Vietnam and Malaysia has also received positive evaluations from J.P. Morgan, which believes this will enhance these companies' competitiveness in the global semiconductor supply chain.

Regional Policy Dividends Drive Industrial Upgrading

In 2026, Southeast Asian governments have successively introduced policy measures to support the development of the semiconductor industry, and these policy dividends are becoming an important factor affecting US semiconductor ratings. From tax incentives to R&D subsidies, from talent development to infrastructure construction, Southeast Asian countries are actively building an ecosystem conducive to semiconductor industry development, providing strong support for the local investments of US semiconductor companies.

In the first half of 2026, Singapore's Economic Development Board launched the 'Semiconductor Manufacturing Initiative 2.0', providing funding support of up to S$3 billion, focusing on attracting investment in advanced packaging and testing. This policy has directly led to rating upgrades for the US packaging and testing sector, with companies like ASE Holding and Amkor Technology receiving 'Buy' ratings from UBS and Deutsche Bank. UBS pointed out in its research report: 'Singapore's policy support will accelerate the industrialization of advanced packaging technology, bringing new growth points for US packaging and testing companies.'

Meanwhile, Thailand's 5 billion baht advanced packaging special fund and Malaysia's 'Semiconductor Strategy 2.0' plan have also received widespread attention from international investment banks. Bank of America Merrill Lynch stated in its latest research report: 'Southeast Asian governments are promoting semiconductor industry upgrading through a combination of policies, which will change the competitive landscape of the regional semiconductor industry and create new investment opportunities for US semiconductor companies.'

Regional Industry Chain Restructuring Brings Investment Opportunities

With the restructuring of the global semiconductor industry chain and the deepening of regional trade agreements, a new semiconductor industry ecosystem is forming in the Asia-Pacific region. This trend is changing the valuation systems of semiconductor companies and bringing new opportunities for investors. Especially under the RCEP framework, the integration of the semiconductor industry chain in the Asia-Pacific region is accelerating, providing US semiconductor companies with broader market space and more efficient supply chain layouts.

UBS analyzed the impact of RCEP on the semiconductor industry chain in its latest research report: 'The implementation of RCEP is accelerating the integration of the semiconductor industry chain in the Asia-Pacific region, especially the coordination of chip design, manufacturing, and packaging/testing links. For US semiconductor companies, this can not only reduce supply chain costs but also better cope with the uncertainty of the global trade environment. We are optimistic about semiconductor companies with complete layouts in the Asia-Pacific region.'

Specifically, the expansion of TSMC's (TSM) advanced packaging bases in Singapore and Japan, and Samsung Electronics' storage chip factory construction in Vietnam have received positive evaluations from multiple investment banks. Morgan Stanley believes: 'The restructuring of the Asia-Pacific industry chain is creating new investment opportunities, especially for companies that can leverage core advantages in regional coordination.'

Investment Strategy Recommendations and Risk Warnings

Based on the current rating dynamics of the US semiconductor sector, multiple international investment banks have proposed corresponding investment strategy recommendations. Overall, AI-driven computing power demand growth and Southeast Asia capacity expansion have become the main focus of semiconductor investment in the second half of 2026. Investors should focus on companies with technological advantages in AI chip design, advanced packaging, and memory sectors, while also having production capacity layouts in the Southeast Asia region.

Goldman Sachs suggests investors focus on three major investment directions: first, leading companies focused on AI chip design, such as NVIDIA and AMD; second, companies with advanced packaging technology advantages, such as Amkor Technology and ASE Holding; third, manufacturing companies benefiting from Southeast Asia capacity expansion, such as Intel and Samsung Electronics. The investment bank believes these companies will face dual opportunities of performance growth and valuation enhancement in the second half of 2026.

However, investors also need to pay attention to the risk factors facing the semiconductor industry. Morgan Stanley reminded in its research report: 'The semiconductor industry has obvious cyclical characteristics, and the current high prosperity may face callback risks.
