TL;DR

· Citi upgrades Chinese stocks to overweight, tactically downgrades South Korea, maintains overweight on China and Taiwan markets.

· MSCI EM targets 1870 points by end-2026 and 2050 points by mid-2027, with earnings upgrades still concentrated in IT.

· This bullish view still has boundaries; EM global allocation remains neutral, and the rally has not yet truly broadened.

According to Citi's latest emerging market strategy report, Citi upgrades Chinese stocks from neutral to overweight, while tactically downgrading South Korea from overweight to neutral, maintaining overweight on China and Taiwan markets, and setting targets for the MSCI EM index at 1870 points by end-2026 and 2050 points by mid-2027.

The most direct market hook of this report is that after the MSCI EM has risen about 20% year-to-date, Citi still believes the index has upside. Based on the current level of about 1664 points, 1870 points corresponds to about 12% upside. 2050 points is higher, and Citi says there is about 20% upside by mid-2027.

But Citi is not betting on an indiscriminate emerging market bull run. Over the past period, EM gains have mainly come from South Korea, China and Taiwan tech, and the AI hardware chain, while other countries and sectors have not kept pace. China was upgraded to overweight precisely because Citi is starting to look for "diffusion" candidates beyond the AI chain.

South Korea nearly 40%, China and Taiwan markets over 30% positive returns, this year's EM rally is highly concentrated.

South Korea's pullback and other markets have not yet formed a full relay

China upgraded to overweight, South Korea cools first

In this round of allocation adjustments, China was raised from neutral to overweight, and Mexico was upgraded to neutral. South Korea was downgraded from overweight to neutral, while China and Taiwan markets remain on the overweight list.

China's appeal mainly comes from three points. Overseas investors are still underweight Chinese stocks, so if global risk appetite improves, there is more room for capital to flow back. Falling oil prices benefit energy-importing markets like China. After global growth data improves, some cyclical assets regain support, and China ranks high among these macro-sensitive markets.

This is different from the main theme of emerging markets over the past two years. Previously, the strongest trades were concentrated in the AI hardware chain, with South Korea and China and Taiwan markets becoming the biggest winners due to demand for semiconductors, memory, and AI servers. But if the index is to continue rising, relying solely on a few tech stocks will become increasingly difficult, and capital needs to find more markets that can sustain the rally.

South Korea's downgrade does not mean its fundamentals have weakened. Public reports show that Citi still maintains a strong long-term view on the South Korean stock market, with local strategists having set a KOSPI target of 10,000 points. According to the source report, the logic behind this includes that memory shortages may extend into 2027, and AI token growth and customization demand will continue to boost the memory cycle. The short-term problem is that South Korea has risen too much, implied volatility is high, and retail leveraged products have amplified fluctuations.

The China and Taiwan market remains one of the most direct beneficiaries in the AI hardware chain. According to the source report, local strategists set a mid-2027 target of 53,500 points for the Taiwan Weighted Index. But this market also faces similar issues: trading is already crowded, and once AI capital expenditure returns spark greater controversy, volatility often first reflects in these early winners.

EM still has room, but earnings upgrades remain narrow

Citi's two targets for MSCI EM are the clearest numerical judgments in this report: 1870 points by end-2026 and 2050 points by mid-2027.

The support is not from significant valuation expansion. The current 12-month forward P/E of MSCI EM is about 11.5 times, roughly close to the long-term average. After this year's emerging market rally, valuations have not been pushed into obvious bubble territory, and the index's rise is more due to improved earnings expectations.

Earnings numbers look strong. MSCI EM's 2026 EPS growth expectation reaches 63%, with cumulative upward revisions of 28 percentage points since the end of February. Growth in 2027 is expected to slow to 24%, but still higher than similar assets in developed markets.

The problem is that the source of earnings improvement remains very narrow. In the 2026 EPS upward revisions, the IT sector contributes about 85%, with South Korea and the China and Taiwan AI chain still being the largest sources. Revisions in most non-tech sectors such as consumer, real estate, and utilities remain weak. That is, the EM index appears to have earnings support on the surface, but earnings upgrades have not yet expanded to more industries.

MSCI EM 2026E EPS growth of 63%, with IT sector contributing about 85% of the upward revision.

This is also why Citi has not upgraded EM to overweight in global asset allocation. Within the region, weights can be increased in markets like China, but at the global asset allocation level, emerging markets remain neutral. Citi's stance is closer to "selectively adding to diffusion beneficiaries" rather than confirming a full-blown bull market.

So-called diffusion means the rally must leave the few AI winners

Citi's "diffusion trade," in plain language, means that this year's emerging markets cannot continue to rely solely on South Korea, China and Taiwan markets, and the AI chain to rise. Capital must either find new countries and sectors, or the index's subsequent upside will be limited.

This screening mainly looks at several conditions. Whether the market benefits from a weak dollar and falling US Treasury yields, whether it benefits from falling oil prices, how it has historically performed when global economic data improves, whether short-term earnings revisions are turning positive, and whether current trading is already too crowded.

Under this framework, China, South Africa, and Mexico rank high. According to the source report, China, South Africa, and Mexico scored 4.2, 5.0, and 5.3 respectively in the "diffusion candidate" screening. South Korea and China and Taiwan markets, while still recent winners, have more prominent short-term crowding and volatility issues.

Oil prices are a realistic condition. Citi's baseline assumption is that oil prices will average about $75 per barrel in Q3 2026, then fall to $65 per barrel by early 2027. Falling oil prices typically benefit energy-importing markets such as South Korea, China and Taiwan, India, and China, while putting pressure on some resource and oil-sensitive markets.

The "Broadening Candidates" table shows China, South Africa, and Mexico ranking high, with dimensions including weak USD, US Treasury yields, oil prices, and crowding.

The key background for China's upgrade is also here. It is neither the strongest market in terms of gains this year nor the most crowded trade in the AI hardware chain, but under the combination of improving global growth, falling oil prices, and position covering, it has the conditions to absorb capital rotation.

Diffusion is not yet complete, AI chain remains the biggest divergence

The caution in this report is that Citi has not written "diffusion" as an accomplished fact.

This year, EM gains are highly concentrated, and the cross-market return dispersion has risen to a 25-year high. South Korea, Taiwan China tech, and the AI sector have contributed almost all index-level returns. If future earnings revisions remain confined to the IT sector, the so-called diffusion is more like short-term portfolio adjustments rather than broad fundamental improvement.

AI capital expenditure is also one of the biggest uncertainties. Previously, the market was willing to give higher expectations to memory, semiconductors, and AI infrastructure because training and inference demand continued to drive computing investment. But if investors begin to question the return on capital expenditure, previous winners like South Korea and Taiwan China may face greater pressure.

Macro risks have not disappeared either. If geopolitical tensions escalate again, oil prices may deviate from the downside scenario. Fed policy remains divided; if rate cuts fall short of expectations, the USD and US Treasury yields will suppress emerging markets. A potential super El Niño could also bring new inflationary pressures.

Citi's EM country allocation table shows overweight in China, South Africa, and Taiwan China markets, with South Korea reduced to neutral.

Citi's judgment on emerging markets is more like "the rally has a chance to broaden" rather than "a full bull market has been confirmed." China was upgraded because it has better odds in this round of diffusion trading. South Korea was downgraded, indicating that previous winners are not necessarily unable to continue rising, but short-term gains and volatility have weakened their appeal.

Whether MSCI EM can move towards 1870 or even 2050 points depends not only on how much the AI chain can rise further, but also on whether non-tech sector earnings can stop being revised down, whether the global cycle improvement can be sustained, and whether capital is truly willing to flow from a few winners to more markets.
