Black Sesame International, a Chinese chip maker focused on autonomous-driving systems, slumped in its Hong Kong trading debut as market turmoil dented investors’ appetite for risk and a sell-off in global technology stocks resumed.

The stock sank 27 per cent to HK$20.45 at the close of trading on Thursday, versus its offering price of HK$28, valuing the entire company at HK$11.6 billion (US$1.5 billion). The broader market was subdued, with the Hang Seng Index adding 0.1 per cent and the Tech Index losing 0.5 per cent.

The firm’s initial public offering (IPO) is the second under the local stock exchange’s Chapter 18C rule, which eases requirements for specialist technology firms. Black Sesame raised HK$1.04 billion from the sale of 37 million shares, one of the biggest deals this year after tea shop chain Sichuan Baicha Baidao and plane assembler Cirrus Aircraft.

“This listing makes us the first autonomous driving AI chip stock on the Hong Kong stock exchange, and also the first in Asia and even Europe,” said Shan Jizhang, founder and CEO at the Black Sesame. “Standing at a new starting point, we will actively embrace the vast market opportunities” in the industry, he added.

The debut was preceded by a market sell-off this week that wiped out more than US$6 trillion from global equities. Concerns about a US recession, overpriced artificial intelligence-driven tech stocks and the Bank of Japan’s rate increases combined to spook investors.
