Fluctuations in Taiwan-based smartphone camera lens supplier Largan Precision Co’s (大立光) share price triggered a price stabilizing mechanism on the local main board yesterday, leading to 22 brief trading suspensions of the shares in the morning session, the Taiwan Stock Exchange (TWSE) said.
The TWSE said that trading of Largan shares was suspended for two to three minutes 22 times before 10am, after the exchange’s price stabilizing mechanism found some irregularities in trading orders.
Under the price stabilizing mechanism, as long as a price-matching simulation system finds that a share could rise or fall more than 3.5 percent after matching potential buyers and sellers on a trial basis, trading of those shares will be suspended for two to three minutes during the TWSE’s call auction, where buy and sell orders are collected over a fixed period and are matched at the end of the period.
The TWSE said that it has launched an investigation into trading irregularities and that such brief trading suspensions are designed to avoid market speculation by certain traders, which could hurt other investors and even affect the broader market.
Market analysts said it is likely that some institutional investors wanted to push up Largan shares in a bid to lure other institutional investors to follow suit to chase prices, but those who boosted Largan shares would take advantage of the soaring share price to cut their holdings and lock in profits.
Before triggering the price stabilizing mechanism, the shares continued momentum from previous trading sessions amid optimism about the smartphone camera lens marker’s bottom line.
However, after the suspension, Largan shares fell into negative territory and the weakness continued into the end of the day’s session, which dragged down the broader market, as Largan stock is the most expensive on the Taiwanese market.
Largan shares closed down 3.26 percent at NT$4,010 yesterday on the main board, off an early high of NT$4,245, with 784,000 shares changing hands.
Led by Largan’s downturn, the bellwether electronics sector ended down 0.35 percent and the weighted index on the main board closed down 0.32 percent.
SEASONAL WEAKNESS: The combined revenue of the top 10 foundries fell 5.4%, but rush orders and China’s subsidies partially offset slowing demand Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) further solidified its dominance in the global wafer foundry business in the first quarter of this year, remaining far ahead of its closest rival, Samsung Electronics Co, TrendForce Corp (集邦科技) said yesterday. TSMC posted US$25.52 billion in sales in the January-to-March period, down 5 percent from the previous quarter, but its market share rose from 67.1 percent the previous quarter to 67.6 percent, TrendForce said in a report. While smartphone-related wafer shipments declined in the first quarter due to seasonal factors, solid demand for artificial intelligence (AI) and high-performance computing (HPC) devices and urgent TV-related orders
Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) and the University of Tokyo (UTokyo) yesterday announced the launch of the TSMC-UTokyo Lab to promote advanced semiconductor research, education and talent development.

The lab would leverage “the extensive knowledge, experience, and creativity” of both institutions, the company said. It is located in the Asano Section of UTokyo’s Hongo, Tokyo, campus and would be managed by UTokyo faculty, guided by directors from UTokyo and TSMC, the company said.

Quanta Computer Inc (廣達) chairman Barry Lam (林百里) yesterday expressed a downbeat view about the prospects of humanoid robots, given high manufacturing costs and a lack of target customers. Despite rising demand and high expectations for humanoid robots, high research-and-development costs and uncertain profitability remain major concerns, Lam told reporters following the company’s annual shareholders’ meeting in Taoyuan. “Since it seems a bit unworthy to use such high-cost robots to do household chores, I believe robots designed for specific purposes would be more valuable and present a better business opportunity,” Lam said Instead of investing in humanoid robots, Quanta has opted to invest
EXPANSION: While Gigabyte Technology is optimistic about market demand this year, uncertainty remains due to the impact of potential US tariffs and currency fluctuations Motherboard and graphics card maker Gigabyte Technology Co (技嘉) yesterday said that it plans to launch an artificial intelligence (AI) server assembly line in the US in the second half of this year. The company’s core motherboard and graphics card businesses in the US remain stable, but sales of its higher-priced AI servers still hinge on the development of tariff policies, Gigabyte chairman Dandy Yeh (葉培城) told reporters following the company’s annual shareholders’ meeting in Taipei. Yeh was referring to the “reciprocal” tariffs announced by US President Donald Trump on April 2, which were later postponed for 90 days. While Gigabyte
