Lisi Group (HKG:0526) expects a net profit of up to 50 million for the six months ended Sept. 30, compared with a net loss of 26.2 million a year prior, a Nov. 14 Hong Kong bourse filing said.

Shares of the household product maker surged nearly 18% in Monday afternoon trading.

The firm attributed the forecast to a decrease in valuation loss from the revaluation of investment properties, as well as lower impairment losses on financial and contract assets.
