Here they are, ranked by liquidity. Pls advise if I have missed any good ones (* = has options): GLD - Gold *(tracks gold) *DBA - powershares AG (corn, wheat, soybeans, sugar) *USO - US Oil fund (tracks light sweet crude oil) SLV - Silver (tracks silver) RJA - agricultural total return less liquid but good to watch: *DBC - net commodity index UNG - nat gas *GSG - net commodity index RJI - net comm index RJZ - metals total return RJN - energy total return XLB, XME, OIH, XLE, XLB also avail but I looking for instruments which mimic the commodities rather than an basket of stocks So an equal portfolio of GLD (16.6% ytd) , SLV (33.8% ytd), DBA (26% ytd) , and USO (6.2% ytd) would yield 20.7% ytd.
