Leveraged exchange-traded funds (ETFs), including the 2x leveraged SSO ETF, have the potential to double investor returns, but also come with significant risks, particularly related to volatility.

The performance of leveraged ETFs can result in significant losses, as evidenced by a recent tech sector decline, but some investors may still be drawn to their potential for amplified gains.
