The market attributes the increased volatility across defense and communication-related stocks to renewed military tensions between the United States and Iran. As Middle East-origin geopolitical risks come to the forefront, supply and demand volatility for related theme stocks in the domestic stock market is also expanding.

Looking at valuation metrics, the EPS as of March 2026 is -192 won, indicating a deficit, and thus the PER cannot be calculated (N/A). The estimated PER and estimated EPS are also recorded as N/A. The PBR is 13.86x, the BPS is 746 won, and the dividend yield is N/A. The industry-average PER stands at 60.91x, with the industry-average change at -5.81%.

Analysts suggest that as tensions in the Middle East heighten once again, the stock price volatility of thematic stocks, including Daehan Optical Communication, is likely to persist for the time being, depending on the trajectory of related developments.
