Bottom Line

CMDY is a commodities/real asset fund that invests in commodity futures contracts. The primary purpose of the fund is to hedge inflation risk including the debasement of the USD.  A secondary goal is to diversify a traditional investment strategy and hedge higher interest rates. However, due to various regulations and because of the inherent nature of commodity futures, the great majority of real asset funds have failed to track the price movements of the underlying commodities. An investor must do their due diligence on the fund and make sure it provides returns that are commensurate with its benchmark index.

The following is a partial list of why commodity funds such as CMDY have failed in tracking their benchmark:

  1. High expense load: This fund carries a significant management fee and may incur significant expenses in continuously trading futures contracts.
  2. Free-riding: There is no conclusive means of ensuring the fund manager is not free-riding the fund for his or her own benefit.
  3. Front-running: Commodity funds must roll contracts on a continuous basis and given the predictability of when the contracts expire, it is relatively easy for bad actors to front-run the fund.
  4. Style drift: There is no guarantee the fund manager will not shift styles or benchmarks to obfuscate performance measures if the fund fails to deliver on its investment objective.    
  5. There are various regulatory limitations on '40 Act Funds investing in commodity futures. These limitations have historically placed an undue burden on "trend following" strategies and commodity index funds.
