Emerging-market equities fell for a second consecutive session, weighed down by renewed selling in AI-linked technology shares and extending a rough stretch for the asset class.

Losses Concentrated in Chipmaking Hubs

The downturn is not evenly distributed. The heaviest damage is clustered in markets that host the world's largest chipmakers — the same countries whose stocks carry outsized weight in the MSCI Emerging Markets index, the widely tracked benchmark for developing-market equities.

On July 17, 2026, the MSCI Emerging Markets index dropped 2.6% to 1,620.66 as concerns over AI valuations swept through technology shares. The session pushed the benchmark into correction territory, defined as a decline of more than 10% from a recent peak — still short of the 20% decline conventionally used to mark a bear market.

Taiwan bore a particularly heavy share of the damage during that July stretch, with its stocks sliding 6.5%. Historically, the MSCI EM index has shed between 2% and 3.8% in single sessions during tech-driven selloffs, some of which followed cautious outlooks from companies such as Broadcom, a supplier of custom AI chips and networking gear for data centers.

Korean Chip Giants Under Pressure

By early October 2026, the MSCI emerging Asia index had declined nearly 3.5%, with Asian equities sinking to two-month lows. South Korea's KOSPI, the country's benchmark stock index, posted multiple sessions with losses exceeding 5% to 6%, while shares of Samsung Electronics and SK Hynix — the twin pillars of Korea's memory-chip industry — fell between 7% and 10%.

Korean chip stocks extended their losing streak to a fifth consecutive day as of October 13, 2026. Part of the pressure has come from rising from CXMT, a Chinese memory maker challenging the established Korean suppliers — a rivalry that points to a scenario in which even strong AI demand may not translate into the same level of profits for incumbent memory makers.

Foreign Investors Head for the Exits

In September 2026, foreign investors withdrew $26.3 billion from emerging-market stocks and bonds, marking the first net outflow since June. Flow data of this kind is watched as a barometer of global appetite for the asset class, which is why the September figure stands out as one to monitor: continued withdrawals in October and subsequent months would suggest the July correction was not a one-off shakeout but part of a longer reassessment of the AI trade. The research attributes the broader pullback to two forces: apprehension over whether AI demand is sustainable, and profit-taking after a long rally spanning 2025 and 2026.

Background: How Emerging Markets Became an AI Trade

Semiconductor and technology companies in Taiwan and South Korea now account for a significant share of the MSCI Emerging Markets index, with their combined weight sometimes exceeding 40%. That concentration helped the benchmark ride the AI wave higher during the 2025 and 2026 rally — and it now works in reverse, carrying doubts about AI valuations straight into the index's largest constituents. For the same reason, upcoming earnings and guidance from major AI suppliers could set the tone for Asian chip stocks, much as past EM selloffs followed cautious forecasts from firms such as Broadcom. The research frames any recovery as dependent on renewed confidence in AI-driven profitability and sustainable capital spending.
