Direct Indexing Platform Comparison: Parametric vs Aperio vs Schwab vs Wealthfront (2026)
The platform you land on matters less than the tax and portfolio strategy around it. But you still have to pick one — here's what actually differentiates them.
Quick comparison table
| Platform | Minimum | Fee (typical) | Access | Customization | Best for |
|---|---|---|---|---|---|
| Parametric | $250K–$500K (advisor) | 0.20–0.35% | Advisor-only | Very high | $1M+ with complex tax situations |
| Aperio (BlackRock) | $1M+ | 0.20–0.35% | Advisor-only | Highest (ESG, factor tilts) | $2M+ with ESG or concentrated-stock needs |
| Schwab Personalized Indexing | $100K | 0.40% (first $250K) | Schwab advisors + retail | Moderate | $250K–$1M Schwab clients |
| Wealthfront | $100K | 0.25% (all-in) | Direct (self-serve) | Low | Self-directed, no advisor |
| Fidelity Tax-Managed | $5M+ institutional | Varies | Institutional/advisor | High | Very large taxable accounts |
| Vanguard Personalized Indexing | $100K | 0.20% | Vanguard advisors | Moderate | Vanguard clients, cost-conscious |
Fee percentages above are platform fees only. If you work with an RIA, their advisory fee (typically 0.50–1.0%) is separate and on top. The platform fee is what the SMA manager charges for the direct-indexing infrastructure itself.
Parametric Portfolio Associates
Parametric is the original institutional direct indexing platform — founded in 1994, now owned by Morgan Stanley (acquired 2021). It has the deepest academic research behind its tax-loss harvesting algorithm and the longest track record of any platform in this space.
- Minimum: $250K–$500K for advisor-directed accounts; Morgan Stanley private wealth clients often see higher thresholds in practice.
- Fees: Roughly 0.20–0.35% depending on account size and sleeve configuration. Negotiated through the advisor relationship.
- Access: Advisor-only. You cannot open a Parametric account directly — you need an RIA or registered rep who has a Parametric relationship.
- Portfolio construction: S&P 500, US Total Market, MSCI World, and factor tilts (value, quality, low vol). Supports custom exclusions (individual stocks, industries, ESG screens).
- Tax-loss harvesting: Daily automated monitoring. Among the most sophisticated algorithms available — accounts for wash-sale rules across all positions, not just the harvested pair.
- Multi-account coordination: Parametric can coordinate tax-loss harvesting across multiple accounts if they're all on the platform, which matters if you have several taxable sleeves.
Aperio (BlackRock)
Aperio was acquired by BlackRock in early 2021, which gave it BlackRock's distribution network and capital markets infrastructure. It's particularly strong for clients who need deep customization — especially ESG factor screening, social criteria, and concentrated-stock risk management alongside direct indexing.
- Minimum: Typically $1M+ for new accounts. Some advisors with a deep BlackRock relationship can access lower thresholds.
- Fees: Similar to Parametric — roughly 0.20–0.35%, advisor-negotiated.
- Access: Advisor-only via BlackRock's institutional and wealth distribution channels.
- Portfolio construction: Highly flexible. Factor tilts, ESG criteria at individual-company level, sector overweights/underweights, exclusion lists. Aperio has the most granular ESG customization of any major platform — suitable for foundations, values-driven investors, or clients with specific industry exclusions (e.g., a pharma exec who doesn't want to hold pharma stocks).
- Concentrated-stock overlay: Aperio has a dedicated concentrated-position module. If you own a large block of company stock (from equity comp, inheritance, or a sale), Aperio can build the direct-indexed portfolio to underweight that sector or hedge correlated positions — effectively helping you diversify while harvesting losses from the broader portfolio.
Schwab Personalized Indexing
Launched in 2022 (built on technology Schwab acquired from Motif Investing), Schwab Personalized Indexing is the mass-market direct indexing product. The $100K minimum and 0.40% fee structure make it the most accessible institutional-grade option, but it trades depth for accessibility.
- Minimum: $100K — the lowest of any full-service direct indexing platform.
- Fees: 0.40% on the first $250K; 0.35% on $250K–$1M; 0.25% above $1M. This is the platform fee — advisory fees are separate if you use a Schwab advisor.
- Access: Available through Schwab advisors (including Schwab Wealth Advisory and independent RIAs on the Schwab Advisor platform) and directly through Schwab's retail brokerage for self-directed clients.
- Portfolio construction: S&P 500 and US Total Market. Custom exclusions available. Less granular ESG screening than Aperio, but sufficient for most clients who just want to exclude a few industries or companies.
- Tax-loss harvesting: Automated daily. Solid but less sophisticated than Parametric's algorithm. Works well for straightforward situations; may leave alpha on the table in complex multi-account scenarios.
- Integration: Tight integration with Schwab brokerage and advisor workstations. If your advisor runs on Schwab, this creates the least operational friction.
Wealthfront Direct Indexing
Wealthfront's direct indexing is a different product category than the advisor-accessed platforms above. It's self-directed, fully automated, and embedded in a robo-advisory wrapper. You don't get a human advisor coordinating it with your broader financial plan — it's a software service.
- Minimum: $100K for direct indexing within a Wealthfront taxable account.
- Fees: 0.25% all-in (includes the robo-advisory layer). No separate advisory fee — there's no human advisor.
- Access: Direct, self-serve. Open a Wealthfront account at wealthfront.com.
- Portfolio construction: Wealthfront constructs and manages the US equity sleeve; you get some control over the overall asset allocation but not stock-level customization.
- Tax-loss harvesting: Automated daily. Wealthfront was early to publish its tax-loss harvesting methodology and has been transparent about expected alpha. Coordination across accounts is possible if all accounts are at Wealthfront, but it won't see your held-away assets.
- What you give up: No human advisor to integrate direct indexing with estate planning, Roth conversions, RMD strategy, or concentrated-stock decisions. If you have a complex financial life, this is a meaningful gap.
Other platforms worth knowing
Fidelity Tax-Managed US Equity Index Strategy
Institutional product with $5M+ minimums in the direct channel. Available to retail clients at lower thresholds through advisors on the Fidelity platform. Excellent for very large taxable accounts but not accessible to most individual investors directly.
Vanguard Personalized Indexing
Launched 2022, $100K minimum, 0.20% fee. Accessed through Vanguard advisors. Vanguard's cost-leadership culture is visible in the pricing. Less customization depth than Parametric or Aperio, but hard to beat on cost. Strong choice for clients already in the Vanguard advisory ecosystem.
Canvas (O'Shaughnessy Asset Management)
Now part of Franklin Templeton. $250K minimum. Notable for factor customization and thematic tilts — if you want a direct-indexed portfolio with explicit value or momentum tilts, Canvas is worth exploring. Less widely distributed than the others.
How to actually choose
The platform choice is less important than most investors think. What matters more:
- Does direct indexing make economic sense for you at all? Use the tax alpha calculator to estimate your expected annual benefit vs. fee drag. If the net benefit is under $5K/year, the operational complexity may not be worth it.
- What's your ordinary-income situation? Harvested losses are most valuable when you have high ordinary income to offset (RSU vesting, K-1, consulting income). Low-income years produce less tax benefit.
- What custodian does your advisor use? If you work with an RIA, they typically have preferred platform relationships. Using their preferred platform reduces friction and cost. Switching custodians to access a different platform often isn't worth it.
- Do you have a concentrated position? Aperio's concentrated-stock module is the strongest in the market. If managing a concentrated position is the primary goal, it's worth considering even if the minimum is higher.
- Do you need advisor coordination? Wealthfront is cheaper but self-directed. If your situation includes RSUs, K-1 income, Roth conversions, or estate planning, a fee-only advisor who integrates direct indexing into your full tax plan will likely produce more after-tax value than the fee difference.
Minimum comparison: what $500K in taxable actually gets you
- $500K: Parametric, Schwab, Wealthfront, Vanguard all accessible. Aperio typically not yet.
- $1M: All major platforms accessible. Parametric and Aperio fees drop into the 0.25–0.30% range.
- $2M+: Aperio's concentrated-stock module becomes cost-effective. Multi-sleeve strategies across platforms may make sense. Fee drag becomes a smaller percentage of the tax alpha generated.
- Under $250K: Only Wealthfront or Schwab. At this level, the tax alpha likely barely exceeds the fee. Consider whether a total-return ETF strategy with strategic tax-loss harvesting is a better fit.
Questions a fee-only advisor asks before recommending a platform
- What is your expected annual ordinary income for the next 3–5 years? (Determines how much harvested losses are worth)
- Do you have capital gains carryforwards from prior years that need to be absorbed? (Affects urgency of getting into direct indexing now)
- Is there a concentrated stock position that needs to be managed concurrently?
- What is your tax filing status, and are you subject to NIIT (3.8% on net investment income at $200K/$250K MAGI thresholds)?
- What custodian(s) are your other assets at, and is consolidation desirable?
- Are there ESG, ethical, or sector-exclusion requirements?
These answers determine not just which platform fits, but whether direct indexing is the highest-ROI tax strategy for your situation — or whether Roth conversions, charitable giving, or other approaches should be prioritized first.
