'Massive outperformance': Goldman Sachs on why North Asian stocks are beating those in the south

North Asian equities are outperforming South Asia, with South Korea up more than 80% year-to-date and Taiwan also leading, driven by AI exposure, stronger fiscal buffers, and relative insulation from energy shocks. China’s A-shares are up 10% year-to-date and are outperforming H-shares amid clearer policy support and a return of producer prices to positive territory at 2.8%, while geopolitical tension between the U.S. and China appears calmer after the Xi-Trump meeting. Goldman Sachs cautions, however, that semiconductor valuations in Korea imply limited durability and warns of a possible correction if an energy supply shock hits later this year.

Analysis

The market is still pricing Asia as a single macro trade, but the dispersion is now dominated by three separate engines: energy import sensitivity, index composition, and AI capex leverage. North Asia has the cleaner earnings-to-macro transmission because a larger share of its market earnings are tied to semis, hardware, and automation, while South Asia is carrying the wrong exposure mix for an energy shock regime. The second-order winner is not just exporters; it is any supplier sitting inside the AI capex supply chain with pricing power and an earnings base that can re-rate on forward margins rather than current cash flow.

The bigger risk is that the current leadership is being financed by falling discount rates in the AI complex rather than durable end-demand. At 4-6x forward earnings, the Korean semiconductor group is already pricing a trough-risk-free world; that makes the names highly reflexive to even a modest miss in memory pricing, capex guidance, or export controls. Japan looks more stable tactically, but its AI/robotics premium is vulnerable if the market rotates from growth-duration winners into higher-quality defensives once energy costs start filtering through regional PMIs over the next 2-3 months.

China is the more interesting relative-value setup because the market is separating policy-supported domestic cyclicals from offshore internet/platform exposure. If the mainland policy impulse is real, A-shares should continue to outperform H-shares until earnings revisions broaden beyond the state-linked and industrial names; however, that spread can mean-revert fast if credit transmission stalls. The potential summer correction is the key timing risk: energy inflation would hit the most levered South Asian economies first, but the same shock would also pressure global risk appetite and could knock 10-15% off the most crowded North Asian AI trades in a short window.

The contrarian takeaway is that the current North Asia outperformance may be too one-directional, too consensus, and too dependent on a narrow set of semis and AI beneficiaries. The move is likely under-hedged against a simultaneous oil-up / growth-down scenario, where factor leadership flips from high-beta tech to balance-sheet quality and domestic pricing power. That makes this a good environment to own the structural winners, but only with explicit downside protection and a willingness to fade the most extended semicap names on strength.

Key Decisions for Investors

• Long TSM / short INDA or EWY-tilted South Asia exposure for a 1-3 month relative-value trade; thesis is that AI supply-chain earnings revisions outpace energy-sensitive macro deterioration, with the short leg acting as a hedge against oil shock spillover.
• Buy downside protection on Korean semis: short-dated put spreads on ASML-style duration proxies or, more directly, puts on SK Hynix/Samsung equivalents if liquid; use a 5-10% pullback trigger because valuations already discount near-perfect execution.
• Long EWJ versus short EPI for the next 2-4 months; Japan has a better mix of political stability, robotics/automation leverage, and domestic earnings quality, while India/Indonesia are more exposed to imported energy inflation and margin compression.
• Pair long FXI A-shares / short KWEB H-shares over the next quarter; the spread should benefit if mainland policy support keeps flowing to domestic cyclicals while offshore internet names remain valuation-capped by weaker earnings visibility.
• Hedge AI beta with an energy long: initiate a modest long XLE or Brent call overlay against Asia tech longs for summer-month risk; this offsets the scenario where oil spikes force a broad de-rating in the most crowded growth names.
