ETF Analysis — Fair Value, NAV Premium & Expense Ratio for Every ETF
Analyze ETFs the way you analyze stocks — with transparent data. We calculate NAV discount/premium, compare expense ratios, evaluate underlying holdings quality, and estimate whether you're getting fair value for the basket.
Why Analyze ETFs?
ETFs are the most popular investment vehicle for individual investors, with over $10 trillion in assets under management. Most investors buy ETFs and never look inside. But the quality of the underlying holdings, the fees you pay, and the price you pay relative to NAV all matter for returns.
FairValueLabs extends our fundamental analysis framework to ETFs:
- NAV Analysis — Is the ETF trading at a premium or discount to the value of its holdings?
- Expense Ratio Comparison — How do fees compare within the same category?
- Holdings Quality — What's the aggregate Z-Score, moat rating, and margin of safety of the underlying stocks?
- Category Rankings — Which ETFs in each category offer the best value?
Coming Soon
ETF coverage is expanding. We're building the data pipeline to analyze the top 50 ETFs by AUM across major categories: total market, S&P 500, Nasdaq-100, sector, value, growth, dividend, and bond. Each ETF will get a dedicated analysis page similar to our stock ticker pages.
In the meantime, explore the Best Value ETFs list for our current recommendations, and read ETF vs. Mutual Fund to understand when each vehicle makes sense.

Common questions
How do you analyze ETFs differently from stocks?
ETFs are baskets of securities, so the analysis focuses on: (1) NAV discount/premium — is the ETF trading above or below the value of its holdings? (2) Expense ratio — fees compound against you over time. (3) Holdings quality — what's the aggregate moat rating and financial health of the underlying stocks? (4) Tracking error — how closely does the ETF follow its index?
What is a NAV discount?
Net Asset Value (NAV) is the per-share value of all the securities inside the ETF. When the ETF's market price is below NAV, it trades at a discount — you're buying the basket for less than the pieces are worth individually. This is more common in bond ETFs and less-liquid equity ETFs.
Are lower expense ratios always better?
For index ETFs tracking the same benchmark, yes — lower fees directly increase your returns. But comparing expense ratios across different strategies isn't meaningful. A 0.50% factor ETF that outperforms a 0.03% market-cap ETF by 2% is the better deal despite higher fees.
