Good news from the GTC Conference is materialized, with the A-share computing power sector experiencing a significant drop.

After NVIDIA announced multiple technological breakthroughs at the GTC conference, the A-share computing power industry chain experienced a sharp decline. In the morning session on March 17, optical modules, optical communications, optical chips, and other computing power tracks led the market decline, with most leading stocks giving back nearly 5 days' gains in the morning session. Tianfu Communication, Changguang Huaxin dropped more than 8%, while Dongshan Precision, Guangku Technology, Tengjing Technology, and other popular stocks followed the decline. Analysis suggests that some of the new generation chips announced by NVIDIA are set to be launched in 2028, causing short-term market sentiment disturbance. Although the iteration of related optical communication technology is expected to bring long-term benefits, for funds seeking certainty, the impact of this good news on the subsequent growth of the industry chain is still unknown, compounded by high industry chain valuations and significant short-term pressure for correction due to previous gains.
