On May 27, Cambridge Industries Group (06166.HK) fell 3.01% in regular trading, trading at HKD 141.7/share, with trading volume of approximately HKD 769 million.

The decline comes after a sharp rally in the preceding sessions, with the stock surging 8.9% on May 26 to HKD 154.8 driven by CPO concept activity and strong light module order momentum. The optical communications sector has shown a recurring pattern of profit-taking following sharp gains, as previously seen on May 20 (-4.84%) and May 21 (-3.2%), when the sector experienced sustained selling pressure after rapid run-ups.

The company's fundamentals remain robust, with Q1 net profit surging 276.44% year-over-year and annual light module capacity reaching 3.5 million units. Everbright Securities recently initiated coverage with a Buy rating, citing the company's 800G silicon photonics shipments and 1.6T product ramp as key growth drivers. However, near-term technical selling pressure appears to be weighing on the stock as investors lock in gains from the recent CPO-driven rally.
