As 2013 comes to a close, it's time to reflect on the year's profits and losses.
Bloomberg recently compiled a list of the best and worst investments of 2013. Among the list are a few investments notable for their Oklahoma connections.
The best performing commodity of the year has been natural gas, which closed Thursday at $4.44 per thousand cubic feet, up $1.01, or 29 percent, on the year.
While oil production has increased throughout the region, Oklahoma still is a predominantly natural gas state with many local producers and counties dependent on its production.
The current price is still considered too low for local producers to search only for natural gas, but the higher prices can increase the returns on wells that produce both natural gas and oil.
Much of the price jump this year is because of the challenging low prices the industry faced over the previous three years.
As natural gas prices plummeted to less than $2 per thousand cubic feet, the cost of the relatively clean-burning fuel dropped below that of coal, the dirtier low-cost staple that has fueled most of the country's electricity needs for more than a century.
The price of natural gas also has been boosted by the growing effort to increase the use of natural gas as a vehicle fuel.
While natural gas prices have rallied, the feed stock for another alternative fuel has slumped.
Corn prices have tumbled 39 percent as a record domestic harvest combined with a Chinese ban on some U.S. corn because of genetic modifications. Corn closed at $4.26 a bushel on Thursday, down from $6.98 at the end of 2012.
Corn-based ethanol also faced challenges this year as the country's overall gasoline use has continued to decline.
The Obama administration last month proposed a plan to cut the required minimum ethanol production in the country by 3 billion gallons in 2014.
Sen. Tom Coburn earlier this month announced a plan to kill the ethanol mandate altogether.
Another name familiar to the Oklahoma City business community is set to close out the year as the best performing master limited partnership.
New York-based Icahn Enterprises LP, led by activist investor Carl Icahn, boasts a return of nearly 194 percent on the year.
Icahn has been very busy this year, investing in companies including Apple Corp., Dell, Herbalife Talisman Energy and Oklahoma City-based Chesapeake Energy Corp.
Icahn bought a 7.5 percent stake in Chesapeake in May 2012. In August 2013, Icahn boosted his stake in Chesapeake to 9.98 percent.
Chesapeake shares closed Thursday at $27.72, up more than 76 percent from when Icahn began investing.
Chesapeake's stock growth has not all been led by Icahn's investment, but Icahn — and all Chesapeake investors — have benefitted from the trend.
