Montage Tops CATL as Priciest Dual-Listed Stock After Chip Rally

Montage Technology Co. has overtaken Contemporary Amperex Technology Co. Ltd. as the most expensive dual-listed stock in Hong Kong relative to its mainland shares, propelled by surging demand for AI chips.

Chipmaker Montage jumped 17% in Hong Kong on Wednesday, pushing its shares to a 40% premium over its Shanghai-listed stock, the widest gap among companies trading in both markets. Since its Hong Kong debut in February, Montage’s mainland stock has risen 22% while H-shares have tripled after initially listing at a discount.
