This is a leveraged inverse ETF that tracks -2x the daily performance of the Bloomberg Natural Gas Subindex. It uses natural gas futures and swaps and is designed to deliver double the gain when prices fall.

It suits short-term traders who understand the daily reset structure and want to bet on a short-term decline in natural gas or hedge their energy exposure.

It is a passively managed (index-tracking) ETF run by ProShares.

The fund does not hold physical natural gas. Instead, it uses natural gas futures contracts and swaps to obtain -2x daily exposure relative to the index. Because exposure is reset at the close of every trading day, holding periods longer than one day reflect a path-dependent compounding effect rather than a simple -2x return.

• A -2x inverse structure that bets on falling natural gas prices
• Synthetic exposure based on futures and swaps

Assets under management (AUM) stand at $51.7M, and the total expense ratio is 0.95% per year.

Because of the daily reset structure, cumulative returns can diverge from the natural gas trend during periods of high volatility.

Natural gas prices are highly sensitive to seasonality, inventories, and weather, so the returns of this inverse ETF have also been very volatile. Trends have repeatedly reversed quickly depending on price direction and the size of volatility.

Fund flows tend to swing quickly with short-term directional bets and hedging demand. Trading becomes more active when natural gas prices move sharply, while interest tends to fade during calmer periods.

Its strength is the ability to make a leveraged bet on falling natural gas, but the daily reset and high fees work against long-term holding.

SCO, ZSL, GLL, and DGZ shown in the table are leveraged and inverse products from the same family, betting at -2x or inversely on other commodities such as crude oil, silver, and gold. For more direct access to natural gas itself, you can compare the opposite-direction BOIL (natural gas +2x long), UNG, a natural gas futures ETF, and 1x inverse products to choose the direction and leverage ratio that fit.

Here are the points to review before investing in KOLD. Because it is a daily-reset leveraged product, results vary greatly with the holding period and volatility, so it should be checked in advance of any purchase.

The combination of a daily reset and -2x leverage means that holding through highly volatile periods for a long time can produce losses even if you are right about the direction of natural gas. Roll costs from contango and high fees also erode long-term performance.

It works well as a tactical tool specialized for short-term bearish bets on natural gas and for hedging. It is recommended not as a long-term core holding but for short-term traders with a clear view on direction and timing.
