China Market Midday Review: Defensive Rotation Amid Geopolitical Shocks, Divergence Within AI Theme
Taylor Wilson
A-shares slid across the board after a U.S. strike on Iran rattled regional risk appetite, with ChiNext down over 2% — yet money didn't leave AI; it rotated from equipment names into data-center infrastructure, marking a third straight day of violent swings.
How bad was the morning — and where does it sit in this week's context?
The SSE Composite fell 0.58%, CSI 300 0.98%, and ChiNext 2.29% — the deepest drop. STAR 50 was flat; the SSE 50 bucked the trend at +0.36%.
Combined turnover hit ¥1.75 trillion, up 7.3% from the previous session — a classic "sell-off on rising volume" pattern signaling emotional capitulation.
This means → stitch the three days together: Monday ChiNext dropped 3%+, Tuesday it bounced nearly 4%, today gave it all back. The market is seesawing between AI profit-taking and geopolitical shocks, with no clear direction yet.
What triggered today's drop?
The direct catalyst: a U.S. military strike on Iran escalated Middle East tensions, dragging regional tech stocks lower.
Overnight, U.S. semis added pressure — Nvidia -0.22%, Broadcom -1.12% — making A-share tech weakness unsurprising.
In plain terms = this isn't a new domestic negative for A-shares; it's external geopolitical risk colliding with a market already wobbling at elevated levels, amplifying the swing.
Is AI money actually leaving?
Goldman Sachs flow data: buys ran 1.2× sells. The direction: buying GPU and AIDC power names, selling energy-equipment and semi-equipment names.
This means → capital hasn't abandoned the AI trade — it's rotating out of the most-rallied equipment segment into downstream data-center infrastructure, where fresh policy catalysts sit.
The catalyst: reports of a national AIDC investment plan — China Mobile and China Telecom will operate the bulk of the new data centers, drawing bids into telecom stocks.
Why did large-caps actually rise?
Agricultural Bank of China gained 1.82%, extending its winning streak to four days — mirroring the SSE 50's outperformance.
This reflects defensive money continuing to crowd into big-bank heavyweights — when growth sectors are pinned down by geopolitics, banking blue-chips become the shelter.
What happened to Weichai Power's flash crash?
Weichai Power plunged 7.18% in a single session after a brokerage report circulated claiming gas-turbine overcapacity after 2030.
Goldman's trading desk has already spotted dip-buying — suggesting some capital views the sell-off as overdone.
In plain terms = a textbook case of a high-flying thematic stock meeting a bearish narrative: the claim is still unverified, but the stock priced it in first.
What does the May inflation print tell us?
May CPI came in at +1.2% year-on-year, below the 1.3% consensus; PPI at +3.9%, in line with expectations.
This means → upstream price gains are not passing through to consumers — demand remains soft, a small demerit for the domestic-recovery narrative.
The flip side: weak inflation also preserves room for further policy easing — the central bank faces fewer constraints on rate cuts or reserve-ratio reductions.
