The inclusion of ChangXin Memory Technologies (CXMT) in a broad MSCI gauge of Chinese stocks may strengthen the chipmaker’s position as the most valuable stock on the onshore market, with the move expected to spur passive buying, analysts say.CXMT, China’s biggest maker of dynamic random access memory (DRAM) chips used mostly in electronic products, joined the MSCI China All Shares Index on Monday. The benchmark tracks yuan-denominated stocks as well as mainland Chinese companies trading in both Hong Kong and the US.The company was expected to become the second-largest constituent behind Hong Kong-listed Tencent Holdings, according to analysts.The addition followed MSCI’s rule of fast-tracking inclusions of mega initial public offerings 10 days after the start of trading, compared with the quarterly reviews for normal inclusions.“As China’s leading DRAM maker, CXMT’s inclusion in the main global index system will boost demand for allocations by passive funds and draw more attention to China’s semiconductor and memory industry chains,” Ping An Securities said.CXMT’s high-profile listing, coupled with China’s rising clout in the global semiconductor supply chain, has drawn overseas investors’ attention, even as access to yuan-denominated stocks remains restricted.
