The QD Laser message board has been redesigned, with active posts covering quantum dot lasers, TOPIX inclusion, cooperation with TDK and other topics.
The message board page has been redesigned, and new features, including the display of sentiment ratios for posts made over the most recent week, have been introduced. Users have also been informed that the previous message board remains accessible, improving the overall usability of the service.
The revised criteria for regular TOPIX rebalancing were explained as placing greater emphasis on liquidity, measured by the trading value turnover ratio. The schedule for announcing the selection results and applying the changes has also been posted. For 2026, the announcement is scheduled for 7 October after the market close, with the changes to take effect from the following business day.
In relation to quantum dot laser IR and business developments, the company plans to install an MBE6000 molecular beam epitaxy system to expand production capacity for quantum dot lasers supplied to Datacom. In the smart glasses field, it has also been reported that the company signed a formal business cooperation agreement with TDK. The restart of an existing MBE system was reportedly completed in September.
Posts also refer to plans to exhibit at CEATEC and developments concerning customer certification-related IR, with some suggesting that interest in the stock market is increasing. Many posts express differing views on QD Laser's potential inclusion in TOPIX and expectations for market developments.
