Markets across regions traded the same core question on July 30: how much risk investors are still willing to carry when growth, capital spending, leverage and cash flow all come under tighter scrutiny.
Mainland China: index losses widened beneath the surface
In A-shares, the STAR 50 dropped 5.38%, the ChiNext Index fell 3.97%, the Shenzhen Component Index lost 2.73%, and the Shanghai Composite slipped 0.62%.
The headline move in the Shanghai index looked relatively contained. Breadth told a different story. A total of 83 stocks closed limit down, 3,635 declined, and fewer than one-third of listed names finished higher.
The semiconductor chain took the brunt of the selling. JCET, Tongfu Microelectronics, Huatian Technology and Dongshan Precision all fell by the daily limit. Losses stretched from packaging and testing to PCB, AI chips and optical modules. Cambricon dropped 9.11%, Eoptolink fell 11.89%, and Zhongji Innolight’s A-share declined 9.15%.
Turnover in Zhongji Innolight reached 59.7 billion yuan for the day, the highest single-day figure since listing. The article said that one stock alone accounted for about 2.5% of total turnover across the two mainland exchanges.
There were isolated pockets of resistance. Demingli hit limit up and stayed there through the session, but one gain did not change the broader collapse across the chain.
Microsoft and Meta delivered two different earnings outcomes
U.S. megacap tech earnings produced a split result, and the market treated the two reports very differently.
Microsoft reported fourth-quarter revenue of $90 billion, ahead of the $87.6 billion expected by the market. Azure annual revenue topped $100 billion for the first time, up 41% year over year. The stock rose about 2% in after-hours trading.
The article also pointed to a key accounting change. Microsoft extended the depreciation life of data centers and office buildings from 15 years to 25 years. Chief Financial Officer Amy Hood said on the earnings call that the effect of the change had already been incorporated into guidance.
Microsoft’s capital expenditures came in at $41 billion for the quarter, while free cash flow was $19.6 billion. BNP Paribas has raised its estimate for Microsoft’s fiscal 2027 capital expenditures to between $255 billion and $260 billion.
Meta, by contrast, reported second-quarter revenue of $60.8 billion, also above expectations. Earnings per share were $6.18, below the market estimate of $7.18. Net income was $15.8 billion, down 14% from a year earlier. Operating cash flow was $31.9 billion, while free cash flow was $784 million.
Reality Labs, the unit tied to virtual reality and the metaverse, posted a quarterly loss of $4.6 billion. Meta also raised its full-year capital expenditure guidance from $125 billion-$145 billion to $130 billion-$145 billion. On the call, Mark Zuckerberg said selling computing capacity for short-term profit would be foolish. The market did not reward that argument, and Meta fell more than 10% at one point in after-hours trading.
Retail investors in the U.S. recorded the biggest one-day net selling since March 2020
According to Vanda Research, U.S. retail investors logged their biggest one-day net sale on July 29 since the COVID-driven market crash in March 2020.
Memory names led the selling pressure. Micron fell more than 9%, SanDisk dropped more than 7%, and Western Digital also moved lower. The article placed that selloff alongside the plunge in China’s semiconductor chain on the same day.
Middle East tension pushed crude sharply higher
The article said Iran fired ballistic missiles at the U.S. and that Donald Trump told Fox News there would be a hard response.
Oil reacted immediately. WTI crude jumped 6.56% to settle at $84.46 a barrel, while Brent rose 7.91% to $90.74.
That move put inflation concerns back into focus. The article said the market was already watching the odds of a September rate hike from the Federal Reserve, and the rise in crude added another layer of pressure to that view.
South Korea traded deleveraging even after Samsung’s record results
In South Korea, Samsung Electronics released second-quarter earnings showing revenue of 171.5 trillion won and operating profit of 89.5 trillion won, both record highs according to the article.
Even so, equities sold off. Samsung Electronics shares fell, SK Hynix dropped 5.64%, and the KOSPI lost 1.35%. Citigroup cut South Korean equities from overweight to tactical neutral.
The article added that regulators are considering tighter constraints on leveraged ETFs and that the finance minister has apologized. The market’s focus, in that reading, was deleveraging rather than headline earnings strength.
Hong Kong stocks diverged as southbound inflows stayed strong
In Hong Kong, the Hang Seng Index edged up 0.20%, while the Hang Seng Tech Index fell 1.25%. Tencent gained 1.16%, while Alibaba and Xiaomi moved lower.
Southbound funds posted a net buy of HK$11.7 billion for the day, the second straight session above HK$10 billion and the first such two-day stretch since April 9. Li Auto drew HK$2.1 billion in net buying, while CSPC Pharmaceutical received close to HK$900 million.
The article also said Zhongji Innolight made its formal Hong Kong listing that day at an offer price of HK$980, with its gray-market trading ending down 1.07%.
Turnover stayed high, but money rotated rather than expanded risk
Total turnover across the two mainland exchanges was about 2.36 trillion yuan, the fourth straight trading day above 2 trillion yuan.
Still, heavy turnover did not translate into broader risk appetite. Funds rotated toward banks and liquor names. Industrial and Commercial Bank of China and China Construction Bank hit record highs. Kweichow Moutai rose 3.09%, Wuliangye added 4.51%, and Jinhui Liquor hit limit up. Banks outperformed, and liquor stocks broadly advanced.
Rates, MLCC price hikes and supply disruptions added more pressure points
On policy, the Federal Reserve left rates unchanged. The article said it was the first time in a decade that there were three dissenting votes. A rate prediction tool in Chicago put the probability of a September rate hike at about 63%.
In components, MLCC prices moved higher. Samsung Electro-Mechanics told clients it would raise prices across its product line by 30% from Aug. 1. Taiyo Yuden will follow in September and said delivery times cannot be guaranteed. Fenghua Advanced Technology rose 6.29% on the day and has logged three limit-up sessions in four trading days.
After the July 28 earthquake in Kumamoto, Japan, Taiwan Semiconductor Manufacturing Co.’s Kumamoto plant, Sony’s image sensor factory, Renesas Electronics and more than 10 semiconductor companies were still conducting shutdown inspections, with restart timing unclear.
The article also said China’s State Administration for Market Regulation will hold a photovoltaic industry price compliance guidance meeting in Yancheng on July 31. The agenda includes implementation of general cost accounting rules and curbing irrational competition.
Article source and framing
This article was adapted from a post on the WeChat public account Wang Zhiyuan, with the ID Z201440, written by Wang Zhiyuan. Its core framing is that markets in different regions may look disconnected on the surface, but many were reacting to the same issue: whether balance sheets, cash flow, leverage and capital spending can still support current pricing.
