I was using Fidelity Select Natural Gas Fund, FSNGX, for Natural Resources exposure until about 2 years ago. I had to sell it when my employer moved our 401k to TRP. I never got around to replacing it with anything. Since then, all of the commodity sectors have had big run-ups. If I got back into any NR fund now, I would probably cause a 50% correction, and none of you would ever talk to me again:^( So, I guess all my active managers will have to do the leg work for now on, or until we get that 50% correction. But don't blame me:^)
