MSCI flags IT risk in EM Asia

Highlights

As of Sept. 30, 2026, information technology comprised 49% of the MSCI EM Asia Index, driving nearly 70% of risk and only 35% of earnings.
Semiconductors and semiconductor equipment rose from 13% to 30% of the index weight post-generative AI launch in November 2022, concentrating exposure in TSMC, Samsung Electronics, and SK Hynix.
Sector dispersion in EM Asia is at a two-decade high, prompting MSCI to highlight GICS sector indexes and futures as essential tools for adjusting targeted exposures beyond traditional country allocations.

Sector concentration and AI exposure

As reported by MSCI, the MSCI EM Asia Index is increasingly driven by a narrow set of sector exposures, with information technology representing 49% of the index as of Sept. 30, 2026. That makes IT more than three times the weight of financials, the second-largest sector, after semiconductors and semiconductor equipment rise from 13% of the index to 30% following the public launch of generative AI in November 2022.

The analysis says IT carries close to 70% of the index's risk, well above its portfolio weight, while contributing around 35% of index earnings. MSCI says that pattern points to higher volatility and a richer price-to-earnings profile than the broader benchmark, while sectors such as financials, energy and utilities contribute more to earnings and less to risk than their weights imply.

Companies with an AI-value-chain score above 10% account for 59% of the MSCI EM Asia Index's weight, spanning nearly all of IT as well as much of communication services and roughly half of consumer discretionary. MSCI identifies TSMC, Samsung Electronics and SK Hynix as key AI-linked holdings through chips and memory, arguing that AI exposure now cuts across sectors through both physical infrastructure and digital applications.

Revenue mix reshapes regional exposure

MSCI says country allocations can obscure where companies in the index actually generate business, particularly in sectors exposed to geopolitical friction and tariff risks. While IT is concentrated in Taiwan and Korea, with 57% and 35% of the sector respectively, the sector earns about half of its revenue in the U.S., creating a larger gap between listing location and economic exposure than in other sectors.

Consumer discretionary and communication services remain mostly concentrated in China, meaning sector overweights or underweights also shift national exposure across the region's largest markets. Taiwan, China, Korea and India together account for more than 97% of the MSCI EM Asia Index, but MSCI says sector indexes based on GICS can help investors isolate themes, including AI-linked technology and Chinese internet platforms, that a country-based approach may miss.

The firm says sector dispersion in EM Asia is now at its highest level in more than two decades, strengthening the case for more targeted portfolio tools. Futures on MSCI EM Asia Sector Indexes, alongside cash equities and other instruments, give institutional investors a way to adjust these exposures directly.

Our earlier article on the Nasdaq 100’s recent volatility highlighted how concerns over AI supply chains and higher financing costs pressured technology and semiconductor-heavy stocks. It noted that despite a short-term rebound, the index remained below key moving averages, suggesting fragile sentiment and the potential for continued swings as markets reassessed AI-linked risks.
