Optoelectronics and optical communication-related stocks broadly rose during the morning session on the 7th, with buying spreading across the theme as a whole. Daehan Optical Communication, Bitgwah Electronics, and Bitssam Electronics, along with Kwangjeonja (Optoelectronics), Korea Advanced Materials, Rycom, and FiberPro, are rising in tandem.

The most notable gainer is Daehan Optical Communication, trading at 13,640 won, up 4.84% from the previous session, after rising as high as 14,100 won intraday. Its trading volume of about 3.6 million shares is among the highest of related stocks.

Bitgwah Electronics is trading at 2,810 won, up 3.50%, with an intraday high of 2,940 won and volume exceeding 3.43 million shares. Bitssam Electronics also joined the rally, rising 2.03% to 8,550 won. Kwangjeonja is trading at 7,230 won, up 2.26%, after reaching 7,450 won intraday, with volume surpassing 350,000 shares.

Seoul Semiconductor is up 2.71% at 9,840 won, and Seoul Biosys is up 2.70% at 7,990 won.

Optical communication equipment and component stocks are also mostly firm. Rycom is up 3.08% at 4,180 won, and Jaram Technology is up 2.58% at 21,850 won. Korea Advanced Materials rose 1.83%, FiberPro 1.70%, and Woorinet 1.53%. In addition, Sungho Electronics climbed 3.89%, LS 3.01%, and TMC 2.70%, with gains continuing across the broader related industry group.

However, RFHIC fell 0.10%, and Mercury remained flat.

The market views the optoelectronics value chain—spanning optical fiber, optical communication components, optical devices, and network equipment—as a sector that can continue to attract market attention amid growing data transmission volumes and the advancement of communications infrastructure.

That said, since stocks classified as optoelectronics-related differ in their actual business areas and revenue structures, investors should examine the extent of actual earnings contributions from optical communication components and equipment, optical devices, semiconductors, and network businesses, rather than approaching these stocks solely on the basis of theme inclusion.
