Huaxin Cement (HKG:6655, SHA:600801) said its A-shares logged a cumulative closing price deviation of over 20% across three consecutive trading days through July 23, according to a Wednesday Hong Kong bourse filing.

Hong Kong shares of the company were up about 4% in Thursday's recent trade.

It found no undisclosed material information that could explain the unusual price movement and confirmed operations remain normal, the filing said.

Huaxin also noted that themes including China's Yarlung Zangbo River downstream hydropower station construction have recently received high attention in the market.

Regarding the interest, the company said it has production capacity in the region, which enables it to supply materials for large infrastructure projects.

However, it added that whether it can generate business income from the project, and the scale or profitability of such income, remains subject to uncertainty.
