Shares in Chinese water purification company Ozner Water International rose by more than 14% following a five-week long suspension.
The firm had been accused of making « false and misleading representations » over its profitability by short-seller Glaucus Research last month.
The allegations caused Ozner’s shares to lose a fifth of its value before trading was halted.
On Wednesday, Ozner addressed Glaucus Research’s claims as « unfounded allegations » in a detailed statement to the Hong Kong stock exchange.
« We will not tolerate what seems to be an outright malicious attack on the company for personal gains which harms the company’s reputation and business prospects, » it said.
