Best Value ETFs to Buy — Low Cost, High Quality Holdings
The best ETFs combine low expense ratios with high-quality underlying holdings. We rank ETFs by cost-adjusted expected value — factoring in fees, NAV premium/discount, and the fundamental quality of what's inside.
Our ETF Ranking Methodology
We evaluate ETFs across three dimensions:
Cost Efficiency — Expense ratio compared to category average. A Vanguard S&P 500 ETF at 0.03% saves you ~$270/year per $100K invested compared to a 0.30% competitor. Over 30 years with compounding, that difference is worth over $20,000.
Holdings Quality — We run our stock analysis on the top holdings. What's the average moat rating? What percentage of holdings are in the Z-Score distress zone? A cheap ETF full of distressed companies isn't actually a good value.
NAV Alignment — ETFs should trade close to their Net Asset Value. Persistent premiums mean you're overpaying for the basket. Persistent discounts may indicate liquidity concerns or structural issues.

Why Not Just Buy the Cheapest?
Expense ratio matters, but it's not everything. Consider two S&P 500 ETFs:
- ETF A: 0.03% expense ratio, tracks the cap-weighted S&P 500
- ETF B: 0.15% expense ratio, equal-weights the S&P 500
ETF B costs 5x more in fees, but equal-weighting has historically outperformed cap-weighting by 1-2% annually over long periods (by reducing concentration in the largest stocks and rebalancing mechanically). The extra 0.12% in fees is trivial compared to the potential outperformance.
The lesson: compare expense ratios within the same strategy, not across different strategies. Our rankings account for this by grouping ETFs by category before comparing fees.
Common questions
What makes an ETF 'best value'?
We define value for ETFs as the combination of: (1) low expense ratio relative to category peers, (2) high-quality underlying holdings (strong aggregate moat ratings and Z-Scores), and (3) trading at or below NAV. An ETF can be expensive and still be the best value if its holdings quality justifies the fee.
Should I buy one ETF or several?
For most investors, a single total market ETF (like VTI or ITOT) provides sufficient diversification. Adding sector or factor ETFs makes sense only if you have a specific view on that segment. Over-diversifying across similar ETFs adds complexity without reducing risk.
How often should I rebalance my ETF portfolio?
Once or twice per year is sufficient. More frequent rebalancing generates trading costs and taxes without meaningfully improving returns. Some investors use a threshold approach: rebalance only when an allocation drifts more than 5% from target.
