HONG KONG/SINGAPORE, July 8 (Reuters) - Shares of Momenta

Global opened slightly higher in their Hong Kong debut

on Wednesday, after the Chinese autonomous driving firm raised

about HK$5.89 billion ($751 million) in its initial public

offering.

The stock opened at HK$301 versus its IPO price of

HK$295.60.

Momenta's debut is a key test of investor demand for Chinese

artificial intelligence and advanced technology companies, as

Hong Kong faces a record wave of lock-up expirations after a

strong first-half for new listings.
