Wah Wo Holdings (09938.HK) issued a positive profit alert, expecting a net profit of between 0.7 million and 1.7 million yuan for the six months ending in September, compared to a loss of 1.6 million yuan in the same period last year. The turnaround from loss to profit is mainly due to a significant increase in revenue and gross profit from construction and supporting services, as well as a decrease in fair value losses on investment properties.
