ChangXin Memory Technologies' massive listing is stoking fears that its market debut could pull cash from Chinese equities, as investors raise funds to get a piece of the country's largest memory chipmaker.
The Shanghai STAR Market listing, expected on July 27, has become the latest focus for investors after Chinese technology shares pulled back in recent sessions. CXMT raised $8.6 billion in Asia's largest IPO so far this year.
Tim Sun, senior researcher at financial services firm HashKey Group, said the listing is reinforcing worries over a liquidity squeeze because investors expect CXMT's valuation to rapidly exceed 1 trillion yuan ($139 billion) after listing.
"Once it passes 1 trillion yuan, CXMT will become a primary heavyweight in the STAR Market and semiconductor indices, forcing index funds, active funds, and sector-specific funds to reallocate toward it," Sun said.
Investors are therefore repositioning ahead of time, putting pressure on sectors that had previously led the rally, including memory chips, semiconductor equipment and domestic substitution plays.
The STAR 50 Index, which tracks the largest and most liquid companies listed on Shanghai's technology-focused STAR Market, has slid almost 20% this quarter.
Peter Alexander, founder of Z-Ben Advisors, also said preparations for the IPO are drawing money away from the secondary market. "There is no question that capital is being pulled from the market in preparation for the public listing of (CXMT) shares."
Alexander expects strong initial demand, saying the stock could see "a marked jump in the share price on the first day of trade, maybe even the second day as well," before both the shares and the broader market settle into "a new equilibrium."
Analysts, however, highlighted that the IPO is an "amplifying factor" that has exacerbated the decline, but its not the root cause.
