ATLASETF analysis: look at what is inside before you buy
An ETF is a basket. ATLAS opens the basket and shows its size, cost, yield, returns, its top holdings and its sector and region mix, so you know what you own.
What it does
For each ETF you get the issuer and index, total assets, the expense ratio, yield and dividend frequency, returns over one to ten years, volatility and Sharpe ratio, the top 10 holdings and the full list of positions, and the breakdown by sector and region.
The part most comparisons skip is look-through: two funds with different names can hold much of the same companies. Seeing the individual holdings tells you whether adding a second ETF diversifies you or just doubles the same bet.
Worked example with live data
Real ATLAS numbers, prices as of Oct 26, 2026.
Illustrative fund: a made-up basket of three real stocks with weights 50%, 30% and 20% (the top holding, AAPL, is 50% of the fund). Weighted by those shares, the fund's price sits +41% versus fair value, its average chance of rising in a month is 53% and its beta is 0.92.
| Stock | Weight | Price vs fair value | Chance higher in 21 sessions | Beta |
|---|---|---|---|---|
| AAPL | 50% | +66% | 53% | 1.09 |
| MSFT | 30% | -6% | 52% | 1.11 |
| JNJ | 20% | +50% | 52% | 0.21 |
| Weighted total | 100% | +41% | 53% | 0.92 |
The company data is live; the scenario in this example (amounts, weights or sizes) is an illustration, not a recommendation.
How ATLAS calculates it
Fund-level data (assets, fees, yield, returns) comes from stored fund records. Holdings come with weights and the share of the fund they cover, so you know how complete the list is.
The idea behind valuation look-through is to apply a stock-level measure to each holding and add it up with the fund weights. If the three biggest holdings are all priced well above their fair value, the fund is too, even when its name sounds modest.
Limits you should know
A holdings list is a snapshot, and funds change their positions. Look-through averages hide dispersion: a fund can look fairly valued overall with a few stocks very expensive. Fees and tracking error also matter beyond the holdings.

Frequently asked questions
How do I analyze an ETF?
Check what it holds (top holdings and sectors), what it costs (expense ratio), how concentrated it is and how it overlaps with what you already own.
What is ETF look-through?
Look-through means analyzing the individual stocks inside a fund and combining them with the fund weights, so you see the exposure you actually have.
What is a good expense ratio for an ETF?
Broad index ETFs often charge well under 0.2% a year, while specialized funds can charge more. Compare funds that track the same index.
Can two ETFs hold the same stocks?
Yes, and many do. Large US indexes share their biggest companies, so holding both may add little diversification.
