SMUP ETF: Tracking the -62% Slide in the T-REX 2X Long SMR Daily Target ETF

Key Takeaways

• SMUP is a leveraged single-stock ETF that seeks 200% of the daily return of NuScale Power (NYSE: SMR), a small modular reactor (SMR) developer.
• The fund's share price fell roughly 62% over the trailing 30 days and about 79% over the trailing quarter, reflecting a sharp de-rating across the nuclear and AI-infrastructure complex.
• The decline tracked a broad selloff in high-beta, long-duration growth stocks as interest rates rose and enthusiasm around the AI data-center buildout cooled.
• NuScale's third-quarter results revealed a steep revenue miss and no signed power purchase agreement, triggering multiple analyst downgrades.
• Because SMUP resets its 2x leverage daily, its multi-day returns compound and can diverge significantly from twice the underlying's return.

SMUP Overview and Portfolio Exposure

SMUP is the T-REX 2X Long SMR Daily Target ETF, a non-diversified, leveraged exchange-traded fund that seeks daily investment results, before fees and expenses, of 200% of the daily performance of NuScale Power (NYSE: SMR). The fund launched in July 2025 and carries a 1.50% expense ratio. Under normal circumstances, it invests at least 80% of its net assets in financial instruments, including swaps and other derivatives, designed to provide twice the daily price exposure to SMR.

Unlike a traditional diversified fund, SMUP is effectively concentrated in a single underlying equity through derivative instruments, so nearly all of its portfolio risk is tied to NuScale Power, a pre-revenue nuclear technology company. It is also a daily-reset product: the 2x objective applies to one trading session at a time, and compounding means multi-day returns can deviate materially from twice the underlying's return, especially in volatile markets. The fund completed a reverse share split in March 2026, and its assets under management remain relatively small, which can contribute to wider bid-ask spreads and heightened intraday volatility.

SMUP Price Performance: Last 30 Days vs. Quarter

Over the trailing 30 days, SMUP's share price fell approximately 62%, from roughly $3.00 to about $1.14. The move was not gradual; the fund posted repeated double-digit daily swings consistent with a leveraged single-stock ETF tracking a highly volatile underlying. Over the trailing quarter, the decline was even more severe at roughly 79%, from levels near $5.35 in early August. This longer-term slide underscores how daily reset leverage and persistent negative momentum in the underlying can compound into losses well beyond twice the underlying's multi-month return.

What Drove SMUP Price in the Last 30 Days

The sharp decline reflects pressure on NuScale Power, SMUP's sole underlying exposure. NuScale's third-quarter earnings, released in early November, showed revenue of roughly $0.28 million against a consensus estimate near $3.45 million, a substantial miss even as adjusted earnings per share narrowly beat expectations. Critically, the company has yet to sign a binding power purchase agreement for its planned 6-gigawatt project with financing partner ENTRA1 and the Tennessee Valley Authority, leaving a central catalyst unresolved.

Analyst sentiment deteriorated in tandem. Several firms issued or reaffirmed cautious-to-bearish views, including Sell and Underperform ratings with lowered price targets, while others trimmed targets while retaining Buy ratings. Against this backdrop, the broader market de-risked high-beta, long-duration growth names as interest rates remained elevated and confidence in an aggressive AI data-center buildout weakened. Because SMUP applies 2x leverage to NuScale's daily moves, each decline in the underlying was amplified within the ETF. From what I see, this dynamic explains much of the amplified downside.

What Drove SMUP Performance Over the Last Quarter

The three-month trend reflects a broader sector rotation rather than a single event. Nuclear and small modular reactor stocks, which had rallied sharply on the expectation that AI-driven electricity demand would accelerate reactor deployment, faced sustained selling as rising interest rates compressed valuations for companies with negative gross margins and revenue that remains years away. NuScale shares lost more than half their value over the quarter, and the wider SMR peer group declined by a similar order of magnitude.

As a daily-reset 2x fund, SMUP amplified this directional move through negative compounding: repeated down days on the underlying generated losses that the fund could not simply recover when the underlying bounced, a structural feature of leveraged ETFs that explains the widening gap between the fund's return and twice the underlying's cumulative return.

SMUP ETF Outlook: What Investors Should Watch Next

The factors that pressured SMUP remain in focus. Investors should monitor the interest rate environment and inflation trends, since higher-for-longer rates tend to weigh on long-duration growth assets with distant cash flows. The trajectory of AI data-center power demand is equally important, as it underpins the small modular reactor investment thesis. On a company-specific level, any progress toward a signed power purchase agreement with the Tennessee Valley Authority and ENTRA1, updates on NuScale's cash position and burn rate, and developments in its commercialization timeline and regulatory approvals are likely to drive the underlying. Finally, capital flows into leveraged and thematic ETFs, along with overall risk appetite in growth and speculative segments, will influence both the underlying and the fund's compounding dynamics. I’m watching this closely as the situation evolves.
