Compounding and Volatility Decay Risk: The daily rebalancing of KOLD means its performance over periods longer than a single day will likely deviate significantly from the stated 2x inverse of the underlying index, particularly in volatile markets, leading to potential long-term value erosion.

Inverse and Leveraged Market Risk: KOLD aims to deliver the inverse of the daily performance, amplified by 2x. This means it profits only when natural gas prices fall and suffers amplified losses when prices rise, making it unsuitable for investors expecting long-term gains or in sustained upward trends for natural gas.

Futures Roll Yield Risk: KOLD invests in natural gas futures contracts. The need to roll expiring contracts into new ones can lead to losses if the market is in backwardation (near-month contract more expensive than next-month contract), as KOLD would be rolling its short positions into lower-priced contracts, reducing its potential profit or increasing losses.
