A year or so ago I invested some of my IRA funds in DBA, and DBO (Powershares DB Agriculture Fund, Powershares DB Oil Fund) in order to take advantage of the expected rise in commodity prices. As hoped for, the funds performed well, and I have made a decent return on the investments.
I sat down this morning and read the prospectus for each of the ETFs:
DBO (Oil Fund) is invested 14.64% in Oil Futures Contracts and 80.11% in US Treasuries.
DBA (Agriculture Fund) is invested 13.65% in various agricultural related futures contracts and 87.98% in US Treasuries.
