Thai Union Frozen Products Pcl, jumped 3.5 percent to 74 baht during midday trade, having hit 74.50 baht earlier, after its reported first quarter net profit topped market forecasts.
The world's largest canned tuna maker reported a 93 percent surge in quarterly profit on Thursday due to the price of tuna, which hit a record high in March.
Several brokers rated the shares a buy, with Kiatnakin Securities maintaining the company's target price at 85 baht on expectations of upcoming financial consolidation and lower production costs to help boost performance in the second quarter.
"There is possible growth in second quarter earnings due to weaker shrimp prices helping to cut Thai Union Frozen's production costs, which is reflected by an improvement in the company's gross profit margin," Kiatnakin said.
"Furthermore, Thai Union Frozen will consolidate its financials with Pakfood Pcl in the second quarter, which will likely help see growth in the company's earnings," the broker said.
