Vanguard Digital Advisor

Vanguard Digital Advisor delivers all-Vanguard ETF portfolios backed by the world's largest index fund provider at a net advisory fee of approximately 0.20%, nearly 50% less than the average robo-advisor's cost. Despite its lower fee, it lacks the direct indexing found in #1 Wealthfront, but its passive management approach has historically produced returns that match or beat active strategies over the long term. This makes it the best choice for pure index investors seeking minimal costs and proven methodology.
