Leveraged gold ETFs ProShares Ultra Gold (UGL) and UltraShort Gold (GLL) aim to double or inverse double daily gold moves but suffer from volatility decay due to daily leverage resets. In 2026, this decay caused UGL and GLL returns to diverge significantly from expected multiples of gold's performance, with UGL losing more and GLL gaining less than naive calculations suggest. Additional costs from futures roll and tax complexities add to the drag. Investors holding these ETFs longer than a few days should monitor gold volatility closely and consider lower-risk alternatives like GLD or gold miner ETFs for sustained exposure.
