Recovery of shipping companies and airlines stock price

Airliner and shipping company stocks are up and profitable thanks to OPEC (Organization of Petroleum Exporting Countries) increasing oil production.
June 7 in the morning, Korean Air stock rose 4.01%, escaping the shock of high oil prices. Asiana stock also increased 2.56%, hitting the 2,400 won mark.
HMM (Hyundai Merchant Marine) stock increased 5.44%, Hanjin Shipping rose 2.20% and KLC (Korea Line Corporation) 2.12%.
Part of the reason for Airline stock increases hinge on expectations that oil prices will decrease under increased OPEC petroleum output. Air service demand declined under previous high oil prices.
One insider at Samsung FN said, "Airline stock showed good profits though domestic demand was depressed in April and May. Expectations are that profits will increase 40% during July and August," and added, "Airlines will decrease charges due to high oil prices by increasing costs. Stock prices at present are below par." He recommended buying Korean Air and Asiana stock.
An analyst from LG Investment & Securities said, "Business profit will be insured due to increasing of air service demand despite high oil prices."
He added, "Korean Air will record 6.1% and 7.5% in business profits this year and next. Buying its stock now is a good investment."
