What is a leveraged inverse ETF?
An inverse ETF is an exchange-traded fund (ETF) constructed by using various derivatives to take advantage of a fall in the value of an underlying benchmark. Investing in inverse ETFs works the same way as holding various short positions and involves borrowing securities and selling them, hoping for a later repurchase at a lower price.
