Volatility Expands Amid AI Data Center Investment Trend

Recently, optical communication stocks have shown increased price volatility amid investment trends in AI data centers and high-speed network infrastructure. As business areas vary by company—from optical fiber and optical cables to optical amplifiers and optical communication components—investors need to also examine individual companies' order intake and earnings.

Whether the Rally Continues After the Holiday Is a Key Watch Point

Attention is focused on whether optical communication stocks will maintain their strength in the session on the 6th, which opens after the Foundation Day holiday and the weekend. As many stocks reversed intraday losses to close higher on the 2nd, watch points after the holiday will likely include whether surging stocks such as Bitssam Electronics and Sungho Electronics can sustain their gains, as well as profit-taking movements.

However, theme stocks can see large short-term price swings, so investors should comprehensively check corporate earnings and disclosures, supply and demand conditions, and related news.
