China A-H share premium vanishes as capital favors Hong Kong listings

For years, investors have paid a premium for mainland China-listed shares (A-shares) compared to their Hong Kong counterparts (H-shares) in dual-listed companies. This pricing gap, a fixture of the market, has now significantly narrowed and, in some cases, flipped entirely. This reversal is particularly pronounced in the technology sector, where leading companies like CATL, Montage Technology, and GigaDevice Semiconductor are now seeing their Hong Kong shares trade at a higher valuation than their mainland listings.

This structural shift reflects a changing investor sentiment and a strategic move by Beijing. The A+H policy, designed to encourage high-quality mainland firms to list in Hong Kong, aims to improve pricing efficiency and attract international capital. The narrowing premium suggests that global investors are increasingly viewing Hong Kong as a more attractive venue for accessing China's strategic sectors, particularly in technology and advanced manufacturing.

While some might see this as a short-term arbitrage opportunity, analysts emphasize the underlying structural changes. The re-rating of Chinese assets, especially in technology, indicates a deeper recalibration of risk and reward by global capital. This development is crucial for Hong Kong's ambition to remain a key international financial center and for China's broader strategy of integrating its capital markets.

This is in line with [Beijing’s] A+H policy introduced earlier, which encourages high-quality and promising mainland companies to list in Hong Kong.
