What Is an Inverse ETF
Can't you make money when the market seems about to fall? The product built from that idea is the inverse ETF. But 'it rises when the market falls' is only accurate for a single day.
The structure of an inverse ETF
An inverse ETF is a product designed to track the opposite of the underlying index's 'daily return.' If the index rises 1% today, the inverse ETF aims to fall about 1% that day, and if the index falls 1%, it aims to rise about 1%.
Unlike an ordinary ETF, which actually holds the index's constituent stocks, an inverse ETF creates a 'downside bet' position using derivatives such as futures, options, and swaps. And like a leveraged ETF, it does a 'daily reset,' realigning to its target at the close of every trading day.
The limit of the daily reset: it diverges once you cross a day
An inverse ETF's '-1x' is a daily-basis target. Once you go beyond a day, the daily returns compound, so the result differs from 'earning exactly the opposite of how much the index fell.'
Especially in a volatile, choppy sideways market of ups and downs, even if the index eventually returns to where it started, an inverse ETF can incur a loss. That's because the result is governed by the 'order of daily movements (the path),' not the final index level.
So an inverse ETF is a product designed for sub-daily short-term directional bets or brief hedges (defending held assets), and is unsuitable for long-term, passive holding.
The U.S. FINRA and SEC warn that daily-reset inverse and leveraged ETFs are unsuitable for ordinary individuals who intend to hold beyond one trading day.
Korea's 'gop-verse' and regulation
In Korea, a 2x inverse ETF is commonly called 'gop-verse' (multiply + inverse). It's a product that aims, on a daily basis, to rise about 2% when the index falls 1%.
Because the gop-verse carries a multiple, compounding erosion works even more severely, so the risk of loss when held long-term is especially large. Domestically, leverage-type products like 2x inverse are included among the products subject to mandatory prior education and the KRW 10 million base-deposit requirement.
Unlike its attractive name of 'bear-market defense,' you must remember it's a structure where you have to get both direction and timing right, and the longer you hold, the more disadvantageous it becomes.
常见问题
Q. Is an inverse ETF the same as short selling?
The purpose (profit when prices fall) is similar, but the structure differs. Short selling means borrowing stock to sell and buying it back later, while an inverse ETF means 'buying' a product that creates a downside position with derivatives, so buying and selling it in your account works the same as an ordinary stock. But a big difference is that, because of the daily reset, an inverse ETF's long-term performance diverges from 'the opposite of the index's decline.'
Q. If I'm sure the market will fall, can I hold it long-term?
No one can be certain 'it will definitely fall,' and even if the direction is right, there's a problem. Even if the index is in a downtrend, if it rebounds and churns in between, the compounding effect of the daily reset can make the inverse ETF's return fall short of expectations, or even turn to a loss.
