Your Biggest Fund May Be A Bad Deal
This simple screen finds the rare funds built to be permanent, cheap, and fairly valued right now.
The S&P 500 has been on a rapid run, a run that makes it easy to ignore the fine print. In a chase for returns, investors often end up in funds that are too expensive, too volatile, or bought at a valuation peak, turning a good market into a poor personal outcome.
This Screen Demands Discipline.
It looks for the rare combination of permanence, price, performance, and prudence. Out of 131 US-focused equity ETFs on our scorecard, just 12 funds clear every bar: they must be large enough to last, cheap enough to hold forever, show no evidence of a skill deficit, and trade at a reasonable valuation compared to their own history. The table below shows the top qualifiers, ranked by the assets they manage.
| Ticker | Fund | AUM | Expense | 3Y Alpha | P/E vs Hist |
|---|---|---|---|---|---|
| VOO | Vanguard S&P 500 ETF | $1.7T | 0.03% | +0.1% | +0.1% |
| IVV | iShares Core S&P 500 ETF | $885.5B | 0.03% | +0.1% | +1.2% |
| SPY | State Street SPDR S&P 500 ETF Trust | $782.9B | 0.09% | +0.0% | +0.3% |
| VUG | Vanguard Growth ETF | $393.8B | 0.03% | +3.9% | -20.7% |
| VGT | Vanguard Information Technology ETF | $170.1B | 0.09% | +3.9% | -15.1% |
Of the 12 funds that qualify, the table shows the five largest by assets under management.
While the top funds are S&P 500 trackers, the list also includes funds with a much higher beta, like the Vanguard Information Technology ETF (VGT), whose beta of 1.28 suggests it moves with more intensity than the broader market. VGT and the Vanguard Growth ETF (VUG) also generated a 3-year alpha of +3.9% a year against the S&P 500.
The Anchor Of The Pack
The Vanguard S&P 500 ETF (VOO) tops the list, managing $1.7 trillion in assets for a rock-bottom expense ratio of 0.03% a year. It passed this screen not just for its size and cost, but for its valuation discipline. The fund’s holdings trade at a valuation similar to historical norm, meaning you are not paying a premium relative to its own past. This valuation discipline is crucial, especially when many individual stocks are hitting new peaks.

A Nearly Identical Twin
The iShares Core S&P 500 ETF (IVV) offers a strong contrast, managing $885.5 billion with the same 0.03% expense ratio. It also delivered a 3-year alpha of +0.1% a year, a slight edge over the benchmark it tracks. Yet a closer look reveals its current 1-year alpha is +0.0%, and our scorecard notes this slight edge is fading. It’s a small detail, but it shows how even nearly identical funds can have subtle differences in their recent performance trends.
What A Screen Cannot See
Remember, this is a snapshot based on historical data. A fund’s alpha, valuation, and even its assets can change tomorrow. The screen’s criteria are simply our definition of a stable core holding; your own definition might differ.
This screen is a starting point for identifying funds that have demonstrated the traits of a durable portfolio centerpiece. It is not a buy list. Before making any decision, confirm that a fund’s specific strategy, like US Large Cap Core, aligns with your own long-term financial plan.
Would Your Fund Make This List?
A list like this is one lens on the market. The funds above cleared this particular bar, but the fund you already own may never have been near this screen, and the only way to know is to look it up.
Our ETF Valuation and Performance Scorecard puts every one of these measures – alpha, beta, Sharpe ratio, valuation versus its own history, cost, and concentration – side by side for every major US equity ETF. Run this exact check on any fund you own; it takes seconds, and the result is often not what the fund’s marketing suggests.
The Fund Diversifies. Does The Rest Of Your Wealth?
A fund like this spreads risk by design – which makes it easy to forget the single stock sitting outside it that has quietly grown into a large share of your net worth. That one position is the real exposure, and selling it to diversify hands a slice of the gains to the IRS. There is a way to cap its downside and unwind it tax-efficiently.
