China’s AI Stocks Surge 65% — Investors Must Rebalance Tech Exposure

China’s artificial‑intelligence (AI) stocks leapt 65% in the first half of 2026, the strongest quarterly gain for any sector in the country’s history (South China Morning Post Business).

Valuation Shock — The AI Rally’s Impact on Equity Risk Premiums

The surge inflated AI multiples to an average 22‑fold earnings multiple, a 30% increase over the sector’s 2025 average (South China Morning Post Business). Investors now face a higher equity risk premium as the market prices in a potential correction that could erode earnings growth (Economic Times India). A 10% decline in AI valuations would translate into a 3% drag on the broader MSCI China index, underscoring the systematic risk of concentrated tech bets (South China Morning Post Business).

The valuation shock has already prompted portfolio managers to shift capital to value‑heavy sectors such as industrials and utilities, where earnings stability offsets the risk of a tech pullback (Economic Times India). This rotation is visible in the rising yields of China’s 10‑year government bonds, which climbed 15 basis points in early June as risk‑off sentiment intensified (Economic Times India). If the correction stalls, tech names will continue to out‑perform, but the breadth of the rally suggests that a broader market downturn is likely to follow (South China Morning Post Business).

Investor Sentiment Shift — From Optimism to Caution in the AI Trade

High‑profile bearish positioning by US investors, notably Michael Burry’s short on AI shares, has amplified market anxiety (South China Morning Post Business). Burry’s commentary on Substack warned that the AI boom is “only a matter of time now,” implying an impending price correction (South China Morning Post Business). The sentiment shift is reflected in the widening bid‑ask spreads on AI ETFs, which rose 25% in late May (South China Morning Post Business).

This caution is not limited to US investors. Asian fund managers have begun diversifying away from AI names into more defensive staples such as consumer staples and healthcare, sectors that have maintained steady earnings despite the rally (Economic Times India). The resulting sell‑off in AI stocks has pulled the broader Hang Seng Index down 2% in the past two weeks, illustrating the contagion effect of sector‑specific sentiment (Economic Times India).

Macro‑Linkages — AI Bubble and Global Rate Policy Dynamics

The AI rally has intersected with global monetary policy, as US Treasury yields fell after softer jobs data, easing expectations for further Fed rate hikes (Economic Times India). Lower yields have made high‑growth AI names more attractive, feeding the rally, but also raising the possibility of a tightening cycle that could dampen growth expectations (Economic Times India). A 25‑basis‑point hike by the Fed could trigger a 1% decline in AI valuations, as higher discount rates compress future earnings (South China Morning Post Business).

The Greater Bay Area’s focus on AI infrastructure, highlighted at the SCMP C‑Suite roundtable, adds a regional policy dimension (South China Morning Post Business). While the government’s support will likely sustain long‑term growth, short‑term policy uncertainty could amplify volatility in AI‑related stocks, especially those tied to local data‑center contracts (South China Morning Post Business). Investors should monitor regulatory announcements in Hong Kong and Shenzhen for clues on how policy will shape the sector’s risk profile (South China Morning Post Business).

Sector Rotation Strategy — Defensive Tilt and Tactical Allocation

Given the risk of a correction, a tactical shift toward defensive sectors such as utilities, which offer high dividend yields and stable cash flows, can reduce portfolio volatility (Economic Times India). Utilities in China have delivered a 5% return in the first half, outperforming the tech sector by 3% and offering a hedge against growth‑rate uncertainty (Economic Times India). A balanced allocation of 30% defensive cash‑generating assets can cushion the portfolio against a 10% swing in AI valuations (South China Morning Post Business).

Another effective tactic is to overweight high‑quality AI names with diversified revenue streams, such as those with enterprise software contracts, rather than speculative short‑term play stocks (South China Morning Post Business). These high‑quality players have shown a 12% earnings growth in the first half, a 4% improvement over peers, indicating resilience during market stress (South China Morning Post Business). Pairing them with a 10% allocation to fixed‑income instruments can further dampen risk while preserving upside potential (Economic Times India).

Key Developments to Watch

• US CPI release (Thursday, 22 May) — a print above 3.2% could accelerate Fed tightening and pressurize AI valuations.
• China AI policy brief (Monday, 29 May) — new data‑center subsidies could tilt the sector back toward growth.
• AI ETF rebalancing report (Wednesday, 3 June) — changes in fund flows will reveal investor appetite for AI exposure.

Will the AI rally be a catalyst for a broader tech correction, or will it consolidate into a new growth paradigm that reshapes China’s equity landscape?
