SSE Composite Drops 3% Below 3,800; ChiNext and STAR Market Plunge Over 7%
Miles Bennett
A-shares fell across the board on July 17 — the Shanghai Composite lost 3.05%, closing below 3,800 for the first time since September 2024, with over 5,000 stocks declining; the sell-off resonated with a global AI-bubble squeeze, as markets repriced the crowded tech trade.
How bad was the sell-off?
The Shanghai Composite fell 3.05%, closing below 3,800 — a nine-month low. The Shenzhen Component dropped 5.4%; ChiNext plunged 7.15%.
Over 5,000 stocks declined and more than 200 hit the daily limit down. Turnover reached ¥2.7 trillion, up roughly ¥251.4 billion from the prior session.
This means → this was not a low-volume drift lower — it was a high-volume stampede, with capital actively fleeing rather than passively trapped.
Why did it crack right now?
External trigger: South Korea's central bank hiked rates unexpectedly, sending Korean equities down over 7% in a single session. Korean memory-chip leaders slumped, and global tech volatility fed straight into A-shares.
Internal trigger: mid-year earnings season exposed several high-flying tech names whose growth missed expectations, sparking concentrated profit-taking that cascaded through crowded positions.
Reuters called the day's Asian session a "bloodbath." Wen Xunneng, CEO of Shanghai Zhuliu Asset Management, said "the global AI bubble is bursting" and noted that heavy quant-fund activity in China amplified the swings.
In plain terms = a fire outside, a gas leak inside, and quant algorithms hitting the accelerator — three forces stacking on top of each other magnified the drop.
Who was buying the dip?
Several broad-market ETFs saw sharply higher intraday turnover. E Fund ChiNext ETF (159915) traded over ¥7.8 billion for the day — exceeding the prior session's full-day volume.
ChinaAMC STAR 50 ETF, Huatai-PB CSI 300 ETF, China Southern CSI 1000 ETF, Huatai-PB A500 ETF, and China Southern A500 ETF each topped ¥3 billion in turnover.
This means → institutional money is testing the waters via ETFs on the left side of the trade — a sign of interest, but not confirmation that the bottom is in.
Which sectors held up against the tide?
Power utilities bucked the trend: Guiguan Electric, Shenzhen Nanshan Power, Leshan Electric, and Huayin Electric all hit the daily limit up. The catalyst was June electricity data — power consumption in EV-charging services and internet data services grew 57.1% and 41.4% year-on-year.
Banks also rose: Bank of Qingdao led gains; Xiangcai Co. hit the daily limit up; CCB climbed over 3%. Zhongtai Securities sees full-year bank earnings as highly certain, with net interest margins likely bottoming out.
This reflects a classic panic-driven flight to certainty — utilities backed by hard consumption data, banks backed by earnings floors, both textbook defensive plays.
How hard were tech and pharma hit?
AI hardware slid sharply: Deming Li recorded three consecutive limit-down sessions; Changguang Huaxin, Cambridge Technology, and Accelink Technologies all hit the daily limit down.
Pharma sold off broadly: Joinn Laboratories, Lingkang Pharma, and Baihua Medical all hit the limit down.
Jefferies senior quant strategist Shrikant Kale said the market may be "normalizing earnings-growth expectations for crowded AI beneficiaries" — shifting from pricing in "near-perfect execution and continuous upgrades" to a more sustainable growth trajectory.
In plain terms = the market had been pricing AI stocks as if everything would go right and upgrades would never stop; now it is repricing them as normal companies with normal growth — and the price has to come down.
What comes next?
GF Securities: the catch-up decline in high-flying tech is not yet over, but short-selling momentum is draining fast. With the World AI Conference approaching, sentiment could find a repair window in mid-to-late July.
Founder Securities: the correction is also a risk-release process. Some high-growth, reasonably valued tech names have shed much of their short-side energy. The playbook: "pick stocks, not the index."
Orient Securities: after breaching 3,900, the key support for the Shanghai Composite sits near 3,870 — the same level that has been the critical floor since the "September 24 rally." Whether it holds will be a decisive test for the past two years of gains.
This means → the broker consensus is "not done falling, but not far from the bottom." Next week's earnings from Alphabet and other major tech names will be the key checkpoint for how deep this correction runs.
