Daehan Optical Communication fell more than 10% during trading on the 23rd, showing weakness. This is interpreted as the result of spreading profit-taking sell-offs and risk-asset aversion sentiment in optical communication-related stocks, amid a broad market decline in the domestic stock market.

According to the Korea Exchange, Daehan Optical Communication closed at 14,270 won, down 1,630 won (10.25%) from the previous trading day. During the session, it fell to as low as 14,080 won, with trading volume exceeding 9.43 million shares. Its market capitalization stands at approximately 2.2188 trillion won. The intraday high was 16,500 won and the low was 14,080 won, indicating high volatility.

On this day, the domestic stock market plunged as massive selling pressure from foreign investors and institutions poured in. The KOSPI closed at 8,203.84, down 910.71 points (9.99%) from the previous trading day, and as the decline of more than 8% continued during the session, the first-stage circuit breaker was triggered in the securities market. In the morning, sell-side sidecars were also activated in both the KOSPI and KOSDAQ markets.

The market believes that stocks related to AI infrastructure, optical communication, and data centers, which have recently shown strength, came under profit-taking pressure during the market's sharp decline. Daehan Optical Communication had also been on an upward trend due to recent expectations for supplying high-depth optical cables for AI data centers and forecasts of expanded investment in optical communication infrastructure, but on this day, it could not avoid the broader market's risk-aversion sentiment.

However, the industry is paying attention to the possibility that demand for building optical communication networks, driven by the expansion of AI data centers, will continue in the mid-to-long term. The expansion of AI infrastructure investment by global big tech companies and the increasing demand for ultra-fast data transmission are cited as growth factors for the optical cable and optical communication equipment markets.

Going forward, the direction of the Korean stock market points to the U.S. Federal Reserve's (Fed) interest rate policy and the recovery of foreign investor net purchases as key variables. There is also an analysis that the phase of expanding market volatility may continue in the short term, given the increased volatility following the recent expansion of leveraged investment and the rapid surge centered on technology stocks.
