What is an ETF? -- Part 23: Backwardation and Contango | Page 2 of 2 | ETF Trends

In contrast, if the futures price is below the expected spot price, the futures market is said to be in a state of “backwardation.”

Typically, a futures-based commodity ETF trader would benefit if the underlying commodity is trading in backwardation. Since ETFs have to roll futures to avoid physical delivery of the commodity, a fund gains a profit every time it rolls to a cheaper later-dated futures contract in a backwardated market.

In a contangoed market, the ETF loses money each time it rolls contracts to a costlier later-dated contract. Additionally, potential investors should note that in a contangoed market, futures-based commodity ETFs can experience heavy losses even if the underlying commodity’s spot price rises.
