Piotech Inc. ATuojing Technology's stock resumed trading with wild swings after announcing acquisition of Wuxi Shangji; gross margin decline is a concern.

Semiconductor equipment leader Tuojing Technology resumed trading on July 13, opening 7.09% higher at 890.99 yuan in the call auction to hit a record high, before its share price plunged more than 18% at one point. As of press time, it was up 6.49% at 886 yuan. The company previously disclosed plans to acquire an 82.97% stake in Wuxi Shangji Semiconductor Technology, a 100% stake in Shanghai Taina Micro Enterprise Management, and a 100% stake in Wuxi Kuanxing Enterprise Management. After the transactions, it will directly and indirectly hold 100% of Wuxi Shangji. Tuojing Technology had been climbing in choppy trade since mid-June, with a cumulative gain of 498% before the suspension, but a recent decline in gross margins has become a focus of market attention.
