Growth in oil tanker shares can run a bit longer, analysts and investors say, though they see weakness in dry bulk, liquid natural gas and container shipping extending into 2016 or beyond.

Shippers of crude oil and refined oil products have been able to charge their highest daily rates in years because elevated oil production has led to strong shipping volume. Investors see high volume oil shipments keeping the tanker fleet busy as the Organization of the Petroleum Exporting Countries focuses on market share over oil prices.
"The next 18 months or so should be pretty good," said Ian McDonald, an analyst at asset manager T. Rowe Price, which holds shares of Teekay Tankers, (>> Teekay Tankers Ltd.), which have risen 42.7 percent this year.
Even after that runup, Teekay Tanker is relatively cheap with a 5.4 ratio of enterprise value to earnings before interest tax, depreciation and amortization compared with a 9.3 average since its late 2007 initial public offering, according to McDonald.
Oil tanker investors are also looking forward to winter. Summer rates typically trend lower because capacity is less constrained when seas are smooth and daylight hours are long, making for more efficient trips than in winter when ships are tied up.
Winter heating oil demand will also boost ship use, according to Douglas Mavrinac, analyst at Jefferies in New York, citing industry expectations for an increase in crude demand.
Not so booming are shipping firms specializing in liquid natural gas, where fleets are about 10 percent bigger than they need to be, given slowing growth in demand from key markets including China, Japan and South Korea, said Paul Wogan, chief executive of LNG transporter GasLog. He sees a ramp-up in Australian shipments and increased exports from new U.S. facilities in 2016 improving the outlook in 2016.
Dry bulk shipping stocks also have suffered this year from slowing demand in China for coal and iron ore. Shares in International Shipholding Corp (>> International Shipholding Corporation) have tumbled 60 percent this year, mostly due to weak dry bulk shipping rates.
Fewer new ships are coming online to replace many that are being scrapped, so another 18 months should see some rate improvement in the dry bulk area, said Steven Baffico, chief executive of specialty maritime lender Global Marine Transport Capital.
An oversupply of ships has also constrained container shipping firms like Costamare Inc (>> Costamare Inc), down 10 percent in 2015 and Box Ships Inc (>> Box Ships Inc), down 3.5 percent.
