SPXS Declines 11.6% in 30 Days and 13.9% Over the Quarter as the S&P 500 Advances

Key Takeaways

• SPXS fell approximately 11.6% over the trailing 30 days, moving from a closing price of $26.98 to a latest price near $23.86, as the S&P 500 advanced.
• Over the trailing three-month period, the fund declined roughly 13.9%, extending a downward trend driven by broad large-cap equity strength.
• SPXS is a leveraged inverse exchange-traded fund (ETF) that seeks 300% of the inverse of the S&P 500 Index's daily return; it does not hold individual stocks in the traditional sense.
• The fund's portfolio is dominated by cash and treasury instruments plus S&P 500 index swaps, so index-level moves, not single-stock earnings, drive performance.
• Daily rebalancing creates compounding effects that can cause multi-day returns to diverge from a simple -3x multiple of the index's cumulative move.
• Primary risks include continued equity-market upside, elevated volatility, and the costs of maintaining daily inverse exposure.

Understanding SPXS and Its Portfolio Exposure

SPXS is an exchange-traded fund (ETF) launched in November 2008 and managed by Rafferty Asset Management. It seeks daily investment results, before fees and expenses, of 300% of the inverse (opposite) of the daily performance of the S&P 500 Index. In practice, a 1% daily decline in the S&P 500 is designed to produce roughly a 3% gain for the fund before costs, while a 1% daily gain is designed to produce roughly a 3% loss.

The fund carries a net expense ratio of approximately 1.04% and is non-diversified, meaning it can concentrate risk more than a diversified fund. Rather than shorting hundreds of individual stocks, SPXS uses total return swaps on the S&P 500, with cash and government or treasury money market instruments serving as collateral. Its reported holdings typically number around 13 positions; the largest include the Goldman Financial Square Treasury Instruments Fund, Dreyfus Government Cash Management, Dreyfus Treasury Securities Cash Management, and Goldman Sachs Financial Square Government Fund, alongside multiple S&P 500 Index swap legs.

Because the fund has no conventional sector allocation, its effective exposure is inverse to the S&P 500's composition. The index is heavily weighted toward mega-cap technology, communication services, consumer discretionary, and financials. When those segments rise, SPXS tends to fall; when they decline, SPXS tends to rise. This structure explains why the fund's recent behavior has tracked broad index direction rather than any single industry catalyst. I also checked this using Tickeron’s AI Screener to see how the fund compares to others in the leveraged ETF space.

Price Performance: 30 Days Versus the Trailing Quarter

Using the latest available price of $23.86 and the closing price of $26.98 from the session nearest 30 calendar days earlier, SPXS declined approximately 11.6%. The move was not a straight line: the fund initially edged higher in late July when the index briefly pulled back, then dropped sharply during a broad early-August equity rally before stabilizing near the lower end of its recent range.

Over the trailing quarter, the decline was larger. From a closing price of $27.69 roughly three months earlier to the latest price of $23.86, SPXS fell approximately 13.9%. The quarter's movement was trend-driven rather than range-bound, with intermittent countertrend bounces when large-cap equities paused or pulled back.

What Drove SPXS Over the Last 30 Days

The dominant driver was a rising S&P 500. A widely followed S&P 500-tracking ETF, the SPDR S&P 500 ETF Trust (SPY), advanced about 4.3% over the same trailing 30-day window. Because SPXS is structured to deliver three times the inverse of the index's daily return, a moderately positive index stretch translates into a much larger percentage decline for the fund.

The sharpest losses occurred during a multi-session rally in large-cap equities in early August. In that stretch, the S&P 500 proxy climbed from roughly $747 to about $771, while SPXS dropped from about $26.57 to $24.08. Mega-cap technology and growth-oriented names, which carry substantial index weight, were central to the advance. Improved risk appetite and reduced demand for downside protection also weakened the tailwind that inverse products sometimes receive during volatile periods.

Because SPXS holds swaps rather than individual stocks, no single underlying company drove the decline. Instead, the performance reflected index-level strength, compounded by daily reset mechanics.

Performance Drivers Over the Trailing Quarter

The trailing three-month trend was shaped by a persistent risk-on tone in U.S. large-cap equities. The S&P 500 advanced approximately 4.8% over the period, with gains concentrated in the index's largest constituents. For an inverse fund, a steady advance is especially challenging because the fund resets its exposure daily; in trending markets, daily rebalancing can create volatility drag, causing multi-period losses that differ from a simple -3x multiple of the index's cumulative return.

Sector rotation also mattered. Leadership from technology, communication services, and growth-oriented shares supported the index's advance and left SPXS with few sustained rallies. Meanwhile, cash-like collateral holdings contributed modest interest income but were not enough to offset the equity-driven decline.

Using Tickeron’s AI Screener for Deeper ETF Analysis

One tool I find useful when evaluating leveraged and inverse ETFs like this is Tickeron’s AI Screener. It helps scan thousands of securities using technical indicators, fundamentals, volatility metrics, price patterns, and AI-generated signals, making it easier to compare momentum and setups across funds. I’ve used it to quickly surface candidates that align with specific criteria, which can be especially helpful for tactical strategies.

SPXS Outlook: Key Factors to Monitor

The most important forward-looking factors are the same forces that have driven the fund's recent decline: the direction and pace of the S&P 500, volatility, and the path of daily returns. Investors should monitor Federal Reserve policy expectations, inflation data, and economic growth indicators, since these influence large-cap equity sentiment and the leadership of mega-cap technology and growth shares.

Earnings cycles for the index's largest constituents, sector rotation between growth and value, and changes in equity-market volatility will also be critical. Sustained low volatility and gradual index gains historically create a difficult environment for daily-reset inverse funds, while sharper pullbacks can produce short-term gains. Additionally, fund-specific factors such as net expense ratio, swap costs, and the compounding effects of daily rebalancing remain relevant for any holding period longer than one day.

SPXS is designed for short-term tactical use by investors seeking to hedge or speculate on daily index declines, not as a long-term buy-and-hold position.
