UPRO: The ETF that Provides 3x Exposure to the S&P 500

Investing directly in the UPRO ETF can involve significant risks, including amplified losses and a complexity that may challenge many investors. At alphaAI, we specialize in applying advanced risk management to leveraged instruments like UPRO, making them more accessible for both active and passive investors. Discover what the UPRO ETF truly is, how it functions, and the potential it holds for enhancing your portfolio when managed intelligently.

What Exactly is the UPRO ETF?

The ProShares UltraPro S&P 500 (ticker: UPRO) is a leveraged exchange-traded fund designed to deliver three times (3x) the daily performance of the S&P 500 Index, before fees and expenses. Launched in 2009 by ProShares, UPRO aims to amplify the daily moves of the S&P 500, one of the most widely followed benchmarks representing 500 of the largest U.S. companies.

One way to conceptualize UPRO is as an S&P 500 "power-up." If the S&P 500 rises by 1% in a single day, UPRO seeks to rise by approximately 3%. Conversely, if the index falls by 1%, UPRO aims to fall by about 3%. This leverage makes UPRO a potent tool for capturing amplified upside in bullish markets, but it also magnifies downside exposure.

However, it's crucial to note that UPRO is not simply holding three times the shares of an S&P 500 ETF like SPY. Instead, its actual holdings consist of a sophisticated mix: swap agreements on the S&P 500 Index, S&P 500 futures contracts, and direct holdings in some individual S&P 500 stocks. These derivatives allow the fund to achieve its 3x daily target efficiently, without needing to invest three times the capital directly in equities.

How Does UPRO Achieve Its 3x Leverage?

UPRO employs financial derivatives to create leveraged exposure. The fund enters into total return swap agreements with major financial institutions, where the counterparty agrees to pay UPRO the amplified return of the S&P 500 in exchange for a fee or other consideration. Futures contracts on the S&P 500 provide additional exposure, and direct stock holdings help align the portfolio with the index.

This structure enables UPRO to target 3x daily returns while managing cash efficiently. The fund rebalances its positions daily to maintain the desired leverage ratio, resetting exposure at the end of each trading day. This daily reset is fundamental to how leveraged ETFs operate, and it is the primary reason they are intended for short-term use.

The Critical Role of Daily Resetting and Its Implications

UPRO's objective is strictly daily, it seeks 3x the performance of the S&P 500 each trading day. Over multiple days, returns compound, and this compounding, combined with market volatility, can lead to results that deviate significantly from 3x the longer-term index return.

In trending markets with low volatility, compounding can work in your favor, potentially delivering returns exceeding 3x the index over extended periods. However, in volatile or sideways markets, the daily resets introduce "volatility decay" or "beta slippage." This phenomenon causes the ETF to lose value over time, even if the underlying index ends flat.

To illustrate: Suppose the S&P 500 rises 10% one day and falls 9.09% the next, returning to its starting point. A buy-and-hold investor in the index breaks even. But for UPRO, +30% on day one, followed by -27.27% on day two (3x the drop), results in a net loss despite the index being unchanged.

Over longer periods, this decay compounds, particularly in choppy markets. Historical data shows that while UPRO has delivered impressive returns in strong bull markets (often outperforming 3x the S&P 500 due to positive compounding), prolonged volatility can erode gains substantially.

Risks of Investing in UPRO: Why Leverage Amplifies Everything

Leveraged ETFs like UPRO are inherently high-risk instruments. The primary risks include:

• Amplified Losses: Just as gains are tripled, losses are too. A 10% drop in the S&P 500 could mean a 30% drop in UPRO in a single day.
• Volatility Decay: As explained, holding beyond one day in volatile conditions leads to path-dependent returns that often underperform the expected multiple.
• Drawdown Risk: Historical bear markets have seen UPRO experience drawdowns exceeding 90%, from which recovery requires enormous subsequent gains.
• Expense Ratio and Costs: UPRO has an expense ratio around 0.91%, higher than standard ETFs, reflecting the costs of daily rebalancing and derivatives.
• Not Suitable for Long-Term Buy-and-Hold: ProShares explicitly warns that UPRO is designed for daily use. Long-term holding without active management can lead to suboptimal or devastating results.

UPRO is commonly used by day traders or short-term speculators betting on market direction. For long-term investors, direct exposure without sophisticated risk controls is generally discouraged.

Historical Performance: UPRO vs. the S&P 500

Despite the risks, UPRO has delivered strong historical returns in bull markets. Over the past 10 years (through late 2025), UPRO has achieved annualized returns around 28-30%, compared to about 14-15% for the S&P 500 (as tracked by SPY). This outperformance stems from compounding in upward-trending periods.

However, performance varies dramatically by period. In strong bull runs, UPRO significantly outperforms. During the 2020 COVID crash, UPRO plummeted over 90% at its nadir before recovering. Investors who held through volatility faced extreme swings, while those with timing or hedging strategies fared better.

Long-term backtests (simulating UPRO-like exposure pre-2009) show that in prolonged bulls, leveraged strategies can compound wealth dramatically. But crashes wipe out years of gains quickly due to the asymmetric math of losses.

Why Direct UPRO Investing is Challenging – and How Risk Management Changes that
