With oil now above $50 a barrel, Jim Cramer was shocked that commodities have performed much better than expected this year.
Garner's research in the charts found that commodities could head even higher. Only this time, oil and gas won't lead the charge. It will be led by grains, meats and maybe metals.
Garner warned that the Goldman Sachs index doesn't always paint a clear picture of commodities, because it is heavily weighted towards oil and gas. Nevertheless, she thinks if the index can break out of its next barrier at $380, it could run all the way to the mid-$400s from there.
