Samsung Electronics has achieved a historic milestone by surpassing $1 trillion in market capitalization, becoming the second Asian company after TSMC to reach this landmark. According to Reuters, Samsung's market value reached 1,500 trillion won ($1.03 trillion) in early trading in Seoul on Wednesday, driven by sharp gains in AI-related stocks in the U.S. overnight. Samsung shares were up 12% at 09:52 a.m. in Seoul, significantly outstripping the benchmark Kospi's 5.4% gain. The surge reflects the global AI boom and semiconductor demand that has propelled both South Korean and Taiwanese chip giants to unprecedented valuations.
Taiwan Semiconductor Manufacturing Company (TSMC) has achieved a historic milestone by capturing 14.2% weight in the MSCI Emerging Markets (EM) index, marking the largest single-company weight in 30 years. This surge has propelled Taiwan to become the top-weighted country at 24.84%, overtaking China. TSMC's market capitalization now stands at approximately $2.04 trillion, driven by the global AI boom and semiconductor demand. The company's P/E ratio has surged to around 37.66 as of May 4, 2026, significantly above its usual range, reflecting the massive AI-driven rally. As per The Economic Times, this concentration has created a clear difference in valuations, with TSMC now considered a better-valued play in the AI supply chain compared to traditional emerging market positions.
In stark contrast to the AI boom beneficiaries, India's market capitalization has declined 5% to $4.92 trillion from the start of the year. According to The Economic Times, this decline is attributed to foreign investors' risk-off sentiment that has weighed down India's equity market. India's weight in the MSCI EM index has dropped to 11.94%, its lowest in over six years, down from a peak of nearly 21% in September 2024. This decline is primarily due to India's sector mix, which leans heavily on financials, consumer staples, and IT services, with little direct AI hardware exposure. India's Sensex has fallen 4.49% year-on-year as of May 5, 2026, with MSCI India down 16%, while major Indian companies like HDFC Bank trade at a P/E of about 15.6-15.69 and Reliance Industries at roughly 22.24, aligning more with traditional industries than high-growth tech.
The MSCI EM index now faces significant concentration risks, with the top 10 companies making up 34.64% of the index weight, a level not seen in many years. As noted by Acadian Asset Management, this concentration is now greater than when Chinese mega-caps surged post-COVID. India's major constituents HDFC Bank and Reliance Industries have MSCI EM weights of only 0.79% each, highlighting the limited economic representation. This narrow composition exposes passive funds to substantial risk from individual stocks, as the performance of a few large tech companies heavily impacts overall returns. The structure offers less protection against technology sector downturns compared to more diverse indices, with potential misleading signals if tech stocks face unexpected challenges.
The stock market prospects of both South Korea and Taiwan have been significantly fueled by key semiconductor companies. According to The Economic Times, Taiwan Semiconductor Manufacturing Company (TSMC), the world's largest chip foundry, along with South Korea's Samsung Electronics and SK Hynix, has driven the growth. Samsung - the second Asian company to cross the $1 trillion market cap milestone, after TSMC - along with peer SK Hynix, comprises over 40% of Korea's benchmark Kospi. The AI rally has created a clear difference in valuations, with foreign brokerages favoring Taiwan and South Korea as AI supply chain leaders with better valuations than India, which is now a consensus 'underweight' position.
