New Britain Palm Oil gained more than a third of its value on the Port Moresby exchange this week, closing Thursday at 36.33 kina, after it released positive full-year results.
It ended 2010 with an after-tax profit of $US266.4 million due in part to a higher oil price in the second half of the year.
Those results reflected increased volumes, with total oils shipped up 25.6% to 455,122 tonnes compared to 362,254t in 2009, and an improvement in crude palm oil prices from less than $800/t at the start of the year to more than $1100/t in the second half.
