Congressional stock trading has been a source of public frustration for years, but one ETF has turned that frustration into an investment strategy. The Unusual Whales Subversive Democratic Trading ETF, ticker NANC, lets ordinary investors mirror the disclosed stock trades of Democratic members of Congress. Since launching in February 2023, the fund has grown to roughly $258 million in assets and built a track record that has outpaced the S&P 500 over its short life. Whether that outperformance reflects genuine informational edge or simply a fortunate bet on mega-cap tech is the central question every investor in this fund needs to sit with.
How the Fund Actually Works
Under the STOCK Act, members of Congress must disclose personal stock trades within 45 days of execution. NANC uses those public filings to construct and update its portfolio, effectively giving retail investors a way to track what Democratic lawmakers are buying and selling. The fund is actively managed, meaning its managers are making real allocation decisions based on those disclosures rather than mechanically copying every single trade.
The 45-day disclosure window is the most important structural detail to understand before investing. By the time a trade shows up in NANC’s portfolio, the original transaction could be six weeks old. In a fast-moving market, that lag can matter. A recent piece from 24/7 Wall St. captured the issue directly: “a 45-day disclosure lag in congressional stock trades means NANC’s portfolio reflects past decisions rather than real-time adjustments.”
What Congress Is Actually Buying
The fund’s portfolio is dominated by the companies at the center of the AI infrastructure buildout. NVIDIA leads at 10.45% of the portfolio of the portfolio, followed by Microsoft at 7.49%, reflecting a clear congressional conviction that AI spending will continue to accelerate. These are not passive index weights — they represent active allocation decisions by fund managers interpreting congressional disclosures.
That conviction extends across the portfolio. Alphabet and Amazon round out the top holdings at 5.65% and 5.32% respectively, pushing the fund’s total information technology weighting to 39.3% of the fund. The result is a portfolio that behaves more like a concentrated tech fund than a broad reflection of congressional trading activity.
That concentration is not accidental. Democratic lawmakers have been among the most active traders in the names powering the AI infrastructure buildout, and those bets have paid off. NVIDIA’s business results illustrate why: the company posted revenue of $68.13 billion in its most recent quarter, up 73% year-over-year, with data center demand driving the bulk of that growth. For a fund whose largest single holding is NVIDIA at , that kind of revenue acceleration directly underpins NANC’s outperformance during the AI rally.
Microsoft tells a similar story: Azure cloud revenue grew 39% year-over-year, helping push total quarterly revenue to $81.27 billion. Together, NVIDIA and Microsoft account for nearly 18% of NANC’s portfolio, meaning the fund’s fate is closely tied to the continued dominance of AI infrastructure spending.
Nancy Pelosi’s trades have drawn particular attention. Her husband exercised call options on 20,000 Broadcom shares at an $80 strike price in June 2025, a trade that became public through the required disclosure process and attracted significant media coverage given the gap between strike price and market value at the time.
The Performance Record, Honestly Assessed
Since its launch, NANC has returned 30% compared to the S&P 500’s 24% over the same period. That outperformance is real, and it is largely attributable to the fund’s heavier weighting in AI-driven technology stocks relative to the broader index. Over the past 12 months specifically, NANC returned 20% versus SPY’s 19%, a narrower gap that reflects how the two portfolios have converged as large-cap tech dominates both.
Year-to-date in 2026, the picture has flipped. NANC is down 4% while SPY is down about 2%. The fund’s tech concentration, which drove outperformance during the AI rally, is now amplifying losses as growth stocks face pressure. Microsoft alone is down 17% year-to-date, a meaningful drag given its position as the fund’s second-largest holding.
One analyst at Seeking Alpha argued that “any past outperformance was accidental and that future returns are unpredictable,” rating the fund a Hold. That view is worth taking seriously. A fund that holds essentially the same stocks as the S&P 500’s top tier, but with higher concentration and a built-in reporting delay, does not have an obvious structural advantage.
NANC vs. SPY: What You’re Actually Choosing Between
Comparing NANC to SPY clarifies the tradeoff. SPY tracks the 500 largest U.S. companies with an expense ratio of 0.03%, giving investors broad market exposure at essentially no cost. NANC charges 0.74%, which is meaningful over time. For that premium, you get a portfolio that tilts harder into technology and reflects the trading decisions of Democratic lawmakers, with all the timing uncertainty that entails.
SPY’s technology weighting sits at 32% compared to NANC’s 39.3%. That difference explains most of the performance gap in either direction: when AI stocks surge, NANC wins; when they pull back, NANC loses more. Investors choosing between the two are essentially deciding whether they believe Democratic congressional trading reflects genuine informational advantage or whether the overlap with mega-cap tech is coincidental.
The Republican counterpart, KRUZ, offers a useful contrast. While NANC surged nearly 35% in 2024, KRUZ gained 18% over the same period, reflecting its heavier weighting in energy and financial stocks rather than technology. The performance gap between the two funds is less about congressional wisdom and more about sector exposure.
The Ban Risk That Could End the Strategy
There is a regulatory risk specific to this fund that has no equivalent in a standard index ETF. If Congress passes a ban on members trading individual stocks, NANC’s entire investment thesis disappears. Prediction markets currently put the probability of a congressional stock trading ban before the end of 2026 at 19%, down from higher levels earlier this year. Every prior deadline-based market on this question has resolved to “no,” and the current Republican congressional majority has shown little appetite for ethics reform legislation.
Still, public pressure on congressional trading has grown, with figures across the political spectrum calling for restrictions. The fund’s prospectus and the nature of its strategy mean that legislative change would require a fundamental rethink of the product.
Understanding the Fund’s Structure and Tradeoffs
NANC’s holdings overlap heavily with large-cap technology names, and the 45-day disclosure lag combined with a 0.74% expense ratio are structural differences worth understanding relative to SPY or a dedicated technology ETF. The fund’s performance has tracked closely with its tech concentration rather than any demonstrable informational edge from congressional disclosures.
For investors evaluating the two options, the core distinction is straightforward: SPY offers broad market exposure at minimal cost, while NANC offers a tech-tilted portfolio shaped by congressional trading disclosures, with the structural limitations that entails.
