China’s securities regulator signaled it is open to tweaking the country’s new market circuit breakers after analysts blamed the rules for exacerbating a US$590 billion rout in stocks on Monday.
Policymakers need to “gradually explore, gain experience and make adjustment” to circuit breakers, China Securities Regulatory Commission spokesman Deng Ge (鄧舸) said in a statement yesterday.
The trading rules, which halt exchanges for 15 minutes after a 5 percent drop in the CSI 300 Index and for the rest of the day after a 7 percent retreat, were triggered on Monday as stocks plunged in their worst-ever start to a year.
While the commission reiterated that circuit breakers play an important role in stabilizing the market, Citigroup Inc, Deutsche Bank AG and Nomura Holdings Inc said the rules failed to restore calm on Monday as investors scrambled to exit positions before getting locked in by the halts.
Changes suggested by analysts include widening the threshold for the first halt beyond 5 percent and creating a bigger gap between trigger levels for the initial suspension and the full-day halt.
“This mechanism, as per the Chinese regulation body, aims to reduce A-share volatility,” Citigroup Hong Kong-based strategist Jason Sun wrote in a report. “Instead, to a certain extent, it may raise short-term liquidity fears if investors are not able to cash in [and] out in a timely fashion.”
Chinese shares on Monday began with losses after data showed manufacturing contracted for a fifth straight month and investors anticipated the end of a ban on share sales by major stakeholders at the end of this week.
The first halt was triggered at 1:13pm as losses in the CSI 300 reached 5 percent. Investors rushed to sell after the suspension ended, with turnover peaking in the final minute before a 7 percent slump froze trading in shares, futures and options for the rest of the day.
“Clearly, the tight stops of 5 percent [and] 7 percent of China’s circuit breaker have a ‘magnet effect’ as prices gravitate towards the breaker and prompt a stampede that drains market liquidity,” Bocom International Holdings Co (交銀國際控股) chief China strategist Hao Hong (洪灝) wrote in a report.
Policymakers proposed circuit breakers in the wake of a market crash that saddled many of the nation’s 99 million individual investors with losses.
The new mechanism adds to trading restrictions that include a 10 percent limit on daily swings for individual stocks and a so-called “T+1 rule” preventing investors from buying and selling the same shares in a single day.
Unlike some measures to calm the US$6.5 trillion equity market over the summer, Chinese authorities sought input from market participants when the circuit breaker proposal was unveiled in September last year.
They even made some changes to the rules, including shortening the length of the first halt from 30 minutes to 15 minutes, before implementing them for the first time on Monday. Traders said the halts took effect as anticipated without any major technical problems.
China’s threshold for trading halts looks “quite tight” versus circuit breakers in other markets, Deutsche Bank strategist Yuliang Chang said. In the US, trading is halted temporarily after declines of 7 percent and 13 percent in the S&P 500, and only suspended for the rest of the day if the losses reach 20 percent.
Shares of contract chipmaker Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) came under pressure yesterday after a report that Apple Inc is looking to shift some orders from the Taiwanese company to Intel Corp. TSMC shares fell NT$55, or 2.4 percent, to close at NT$2,235 on the local main board, Taiwan Stock Exchange data showed. Despite the losses, TSMC is expected to continue to benefit from sound fundamentals, as it maintains a lead over its peers in high-end process development, analysts said. “The selling was a knee-jerk reaction to an Intel-Apple report over the weekend,” Mega International Investment Services Corp (兆豐國際投顧) analyst Alex Huang
Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) is expected to remain Apple Inc’s primary chip manufacturing partner despite reports that Apple could shift some orders to Intel Corp, industry experts said yesterday. The comments came after The Wall Street Journal reported on Friday that Apple and Intel had reached a preliminary agreement following more than a year of negotiations for Intel to manufacture some chips for Apple devices. Taiwan Institute of Economic Research (台灣經濟研究院) economist Arisa Liu (劉佩真) said TSMC’s advanced packaging technologies, including integrated fan-out and chip-on-wafer-on-substrate, remain critical to the performance of Apple’s A-series and M-series chips. She said Intel and Samsung
POWER BUILDUP: Powered by Nvidia’s B200 Blackwell chips, the data center would support MediaTek’s computing power demand and business growth, the company said Smartphone chip designer MediaTek Inc (聯發科) yesterday launched a new artificial intelligence (AI) data center with a maximum capacity of 45 megawatts to meet its rising demand for computing power required to develop new advanced chips for AI applications. The company has completed the first-phase computing power buildup at the data center in Miaoli County’s Tongluo Township (銅鑼), providing 15 megawatts of capacity to support its research and development (R&D) capabilities, despite an industrywide shortage of key components, MediaTek said. Supply constraints have plagued a wide range of key components, including memory chips, solid-state drives, power supply units and central
TRANSITION: With the closure, the company would reorganize its Taiwanese unit to a sales and service-focused model, Bridgestone said Bridgestone Corp yesterday announced it would cease manufacturing operations at its tire plant in Hsinchu County’s Hukou Township (湖口), affecting more than 500 workers. Bridgestone Taiwan Co (台灣普利司通) said in a statement that the decision was based on the Tokyo-based tire maker’s adjustments to its global operational strategy and long-term market development considerations. The Taiwanese unit would be reorganized as part of the closure, effective yesterday, and all related production activities would be concluded, the statement said. Under the plan, Bridgestone would continue to deepen its presence in the Taiwanese market, while transitioning to a sales and service-focused business model, it added. The Hsinchu
