Short ETFs enable investors to profit from declines in an underlying index without directly selling short any securities.Investors who think an index will decline purchase shares of the short ETF that tracks the index, and the shares increase or decrease in value inversely with the index, that is to say that if the value of the underlying index goes down, then the value of the short ETF shares goes up, and vice versa.
