Investing in the S&P 500 index is a common approach for long-term investors seeking to build wealth. The average return for the S&P 500 is about 10% per year, reflecting both up and down periods. With sufficient time, that growth can potentially lead to millionaire outcomes.
For investors aiming to reach that goal faster, one strategy is to use a leveraged exchange-traded fund (ETF), such as the ProShares Ultra S&P 500 (SSO). This leveraged ETF is designed to target double the daily performance of the S&P 500. However, leverage increases both upside and downside risk.
The ProShares Ultra S&P 500 has been available to investors for almost 20 years. Since its inception in June 2006, the ETF has delivered average annual returns (by net asset value) of 14.5%. This is notably higher than the S&P 500’s long-term average of about 10% per year.
There is no guarantee that the ETF will continue to produce the same average returns. Still, using the provided assumptions, if an investor invests $10,000 and the fund continues averaging 14.5% per year, the investment would grow to $38,730 after 10 years, $295,214 after 25 years, and over $1 million after 35 years.
A central drawback for most investors is that the ProShares Ultra S&P 500 requires leverage. The ETF borrows money to buy stocks, which can accelerate gains when markets rise, but can also cause faster declines when prices fall.
In the example given, the S&P 500 index is down about 3.8% year to date, while the ProShares Ultra ETF has declined by about 9%. The gap illustrates how leveraged exposure can increase drawdowns during weaker market periods.
Beyond leverage-related risk, the fund charges a relatively high fee. The net expense ratio is 0.87%. The article notes that some of the best S&P 500 tracking ETFs have expense ratios as low as 0.03%, highlighting the potential cost difference versus lower-fee alternatives.
Leveraged ETFs are generally described as better suited for day traders or investors taking short-term positions who are prepared to manage volatility and the risks of daily leveraged exposure. For long-term investors, the article suggests that buying a fund tracking the S&P 500 index may be a more appropriate approach.

Premium gym chains are entering a “golden era” that is ending or already in decline, as rising operating costs collide with shifting consumer preferences toward more flexible, community-based ways to exercise. Long-term memberships are shrinking, margins are pressured by higher rents and facility expenses, and competition from smaller, more personalized…
