Taiwan's stock market saw Lianjun (3450-TW), a surging optical communications stock, drop sharply on its first day under trading restrictions. With shrinking volume, it hit the daily trading limit down and fell below the 500 TWD threshold, reflecting market concerns over overheating.

Taiwan's stock market opened lower on Friday (11th) but rebounded mid-session as large-cap stocks stabilized. However, optical communications stocks faced heavy profit-taking pressure. Lianjun (3450-TW), which had surged recently, was placed under special trading restrictions starting today due to extreme price volatility. The stock will undergo batch trading every two minutes for five consecutive trading days until August 17.

On its first restricted trading day, Lianjun saw a sharp decline in trading volume and continued to fall throughout the session, eventually hitting the daily lower limit ("circuit breaker down") and breaking below the 500 TWD level. The move signals cooling sentiment toward short-term speculative momentum in the sector.

Other optical communications stocks also declined sharply. Strong recent performers such as Hualight Star (3363-TW) and Shangchuan (3363-TW) fell more than half the daily limit, while WaveOptics (3163-TW), Tontek Photonics (6588-TW), and Lianya (3081-TW) dropped 3-4%.

In contrast, Lianya reported July revenue of 501 million TWD, up 19.2% month-on-month and 176.5% year-on-year, exceeding market expectations. Financial institutions noted strong demand for CWL products used in data center silicon photonics. With backend chip packaging capacity gradually ramping up and indium phosphide (InP) substrate supply becoming more stable and diversified, future revenue growth is expected to continue accelerating.
