Shares of Guangzhou CanSemi Technology Inc. more than tripled in their trading debut on the Shenzhen Stock Exchange's ChiNext board on Tuesday, October 14, 2026.

According to Caixin Global, the stock surged 223% as investors piled into the Chinese mainland's sole large-scale producer of 12-inch silicon photonics wafers.

The scale of the rally is striking because the company behind it is not a proven money-maker. Caixin Global reports that CanSemi is an analog chipmaker with massive ongoing losses, yet the market reception was overwhelming.

In a session when Asian stocks lost steam after a chip rout — a backdrop noted by The Star's market coverage — investors chose to look through current losses and price in the company's strategic position in the AI-driven semiconductor build-out.

A loss-making chipmaker tripling on day one is a consensus-breaking result, not a routine listing.

The strong market reception highlights robust investor appetite for domestic semiconductor manufacturers that are positioned to capitalize on the AI boom, Caixin Global reports.

Being the Chinese mainland's only large-scale producer of 12-inch silicon photonics wafers gave CanSemi a scarcity premium that buyers were willing to pay for on debut day.

The appetite for AI-exposed hardware names in the region is not isolated: Caixin Global has separately reported that Chinese AI hardware is drawing strong investor demand, according to Citi, while CXMT shares suffered their biggest drop since their July IPO — showing how violent two-way swings have become in the sector.

CanSemi's blowout was not the only eye-catching debut on October 14.

In Australia, AFR reports that mining giant Glencore had more than $130 million worth of its shares trade as it debuted on the ASX, a much-needed boost after a dearth of fresh listings and the recent high-profile collapse of Firmus' $44 billion float.

Glencore's Australian shares ended the first day at roughly 0.5% of the register, though CEO Gary Nagle has suggested that figure could grow to a fifth of the company over time — an ambition that would require bucking the poor track record of dual listings on the ASX.

For IPO watchers, the question now is whether CanSemi can hold gains that were built on scarcity and AI hopes rather than earnings.

Debut-day surges on ChiNext often reprice sharply once the initial excitement fades, and the company's massive ongoing losses, as reported by Caixin Global, give bears an obvious line of attack.

The contrasting fates of nearby listings — CXMT's biggest drop since its July IPO, per Caixin Global, versus Glencore's steady $130 million of first-day ASX turnover, per AFR — frame the risk: investors are rewarding thematic scarcity, but they are also punishing aggressively priced listings that fail to deliver.
