What happens to the value of an investment in an inverse ETF when the underlying index decreases in value?

In an inverse ETF, the fund is designed to produce returns that are opposite to that of the underlying index it tracks. This means that when the underlying index decreases in value, the value of the inverse ETF will correspondingly increase. The mechanics behind this involve the ETF taking positions that profit from declines in the index, such as short selling or using derivatives.

Thus, if the underlying index falls, the inverse ETF reacts by gaining value, reflecting the inverse relationship it has with that index. This characteristic is what makes inverse ETFs appealing for traders and investors looking to hedge against market declines or to profit from downturns in the market.

While options concerning the value decreasing or remaining unchanged imply direct correlations or no movement at all, they fail to account for the designed purpose of inverse ETFs, which is to leverage their performance against a falling index. The suggestion that the value fluctuates randomly is also misleading since the performance of an inverse ETF is directly tethered to the movements of the underlying asset, adhering to a predictable pattern rather than random behavior.
