DBC vs GSG

DBC and GSG both give diversified exposure to commodities through futures contracts, but their index construction differs. GSG tracks the S&P GSCI, which is heavily weighted toward energy — often more than half the index. DBC spreads its weight more evenly across energy, metals, and agriculture.

That weighting difference drives most of the performance gap between them in any given year.

Because GSG leans so heavily on oil and gas, it behaves almost like an energy fund during oil-price swings — big gains when crude rallies, sharp drops when it falls. DBC's more balanced basket produces steadier, if less dramatic, moves.

DBC also uses an optimized roll methodology that tries to minimize the drag from rolling futures contracts forward, which can help returns in markets where near-term futures are more expensive than longer-dated ones.

If you want broad, balanced commodity exposure as an inflation diversifier, DBC's even weighting and roll optimization make it the more common choice. If you specifically want heavy energy exposure, GSG delivers it.

Both issue K-1 tax forms and suit tax-advantaged accounts better than taxable ones. For a single-metal hedge instead of a basket, compare GLD.
