According to the Nikkei, Apple announced on the 26th that it will hold a new product launch event at 2 a.m. Japan time on September 10 (10 a.m. Pacific Time on September 9). The report suggests that the company is expected to unveil its first foldable model of its flagship smartphone, the iPhone. In response, Apple-related companies such as Murata Manufacturing, TDK, Taiyo Yuden, and Nitto Denko are likely to attract attention.

Defiance ETFs has launched the Defiance AI Capacitors Leaders ETF (Cboe: CAPA), the first U.S.-listed ETF targeting the capacitor supply chain powering AI infrastructure. The fund tracks the BITA AI Capacitors Leaders Index, which holds companies deriving at least 50 percent of revenue from advanced capacitors and passive components used in AI servers, accelerators, and data centers. Top holdings include TDK Corp at 23.0 percent, Samsung Electro-Mechanics at 20.2 percent, and Murata Manufacturing at 18.3 percent. Industry reporting cited by Defiance indicates a single AI server built on Nvidia's GB300 platform can require roughly 30,000 multilayer ceramic capacitors, and Murata expects MLCC shipments into AI servers to grow about 30 percent annually through 2030. Defiance CIO Sylvia Jablonski said the market has spent three years pricing the chips, while CAPA focuses on what powers them, as rack power architectures move from 12 volts to 48 and even 800 volts.

The Nikkei Stock Average fell in the morning session on the Tokyo stock market, closing at 63,240.51 yen, down 1.74 percent from the previous trading day.

The dollar briefly fell to the lower 155 yen range, and Finance Minister Satsuki Katayama referred to the coordinated Japan-U.S. intervention on July 31.

QD Laser, listed on the Tokyo Stock Exchange Growth Market, is developing quantum dot laser technology that is attracting attention as a next-generation solution to heat and power issues in data centers. However, in the fiscal year ending March 2026, quantum dot-related sales amounted to only 174 million yen, or about 13% of total revenue of 1.372 billion yen, indicating the technology is still in the research and development stage. Former institutional investor Ryosuke Izumida points out that the company's strategy of keeping manufacturing know-how secret without obtaining patents carries the risk of falling behind in mass production and ecosystem formation, similar to how plasma televisions lost out to LCD televisions in the past. For the fiscal year ending March 2027, the company forecasts a return to profitability with net income of 441 million yen, driven by an extraordinary gain of approximately 500 million yen from the partial transfer of patents to TDK, but its operating income forecast is only 3 million yen. Currently, in the field of optoelectronic integration, the ELS method adopted by companies such as NVIDIA is leading the way, and it remains uncertain whether quantum dot technology will become the industry standard.
