Longxin concept stocks move in response to the trend; what is the logic behind the surge?

【Caixin.com】 On May 17, domestic DRAM leader Changxin Technology updated its IPO application filing materials for the STAR Market. Its performance has far exceeded market expectations, and the company will be reviewed on May 27. Another storage leader, Yangtze Memory, has also completed the IPO guidance filing with the Hubei Securities Regulatory Bureau, and related concept stocks continue to be strongly favored by the market.

Since May, leveraged funds have been highly concentrated in key targets across the AI and semiconductor industry chains. Optical module leaders such as Zhongji Xuchuang (300308.SZ) and Xin Yisheng (300502.SZ) have seen large inflows of capital, while AI chip targets including Cambrian (688256.SH) and Hailguang Information (688041.SH) have also attracted major capital flows. This shows a consistent preference for computing hardware. Among them, individual stocks in the storage industry chain have been especially prominent. Lanchui Technology (688008.SH), Zhaoyi Innovation (603986.SH), and BAWI Storage (688525.SH) have all moved into the top ranks, echoing the dominant position of the technology track at the industry level. As for optical module leaders, Zhongji Xuchuang has recently surpassed China Ping An based on recent capital inflows, becoming the stock with the largest net inflow of leveraged funds this year.
