Direct indexing is having a moment. Charles Schwab launched Personalized Indexing in 2022. BlackRock acquired Aperio in 2021. Vanguard quietly entered the market in 2023. Wealthfront has had PassivePlus for a decade. Every wirehouse offers some version through their separately-managed-account platforms.
The marketing has converged on a single message: direct indexing is for everyone, you should switch from your ETF, here's the brochure. The reality is more interesting and more honest: direct indexing is right for some accounts and wrong for others, and the boundaries depend on numbers you can calculate yourself.
This article is the decision framework. No marketing, just math.
What direct indexing actually is
Two-sentence definition: instead of holding one ETF that tracks an index (like VOO for the S&P 500), you hold a sample of 60-200 of the underlying stocks weighted to approximate the index's performance. The expected return is roughly the same — but now each stock can be sold independently, which creates a dramatically larger surface for tax-loss harvesting.
The trade-off: the sample isn't the index. There's tracking error — typically 0.5%-1.5% per year for a well-designed direct-index sleeve against the S&P 500. In exchange, you get harvest opportunities at the per-stock level rather than the per-portfolio level. For a high-bracket investor, the tax savings dramatically outweigh the tracking drag.
The five questions that decide
Direct indexing makes sense for you if and only if all five of these are true:
1. Account size: do you have enough to hold 60+ positions?
The minimum economically-rational direct-index sleeve is around $50K-$100K. Below that, you're buying single shares of expensive stocks (BRK.B is over $400/share, NVDA is $1000+ post-2024 split, LLY hit $700 last year). With $30K spread across 60 positions, your average position is $500 — not enough to harvest meaningfully when that position drops 5%.
| Account size | Recommendation | Why |
|---|---|---|
| $0–$50K | Single ETF | Per-position size too small for harvesting to matter |
| $50K–$200K | Direct indexing borderline | Math works but barely; consider whether the operational burden is worth it |
| $200K–$1M | Strong direct-indexing case | Per-position size sufficient; tax alpha is meaningful in dollars |
| $1M+ | Direct indexing is structurally better | Tax alpha at $1M+ is $5K-$30K/year, easily covers any subscription cost |
2. Tax bracket: are you actually paying capital gains tax?
If your federal long-term capital gains rate is 0% (taxable income below ≈$94K MFJ in 2026), the loss harvest doesn't save you anything because you weren't going to pay tax anyway. The strategy is a no-op.
If your effective federal + state capital gains rate is 15-20%, direct indexing pays for itself but the alpha is modest. If your rate is 30%+ (top federal bracket + NIIT + state — which describes most HENRYs in CA, NY, NJ, OR, MA), direct indexing's tax alpha is large.
| Combined LTCG rate | Profile | Tax alpha (approximate) |
|---|---|---|
| 0% | Pre-retirement, low-income year | None — skip direct indexing |
| 15-20% | Middle-bracket, low-tax state | 0.3-0.7% per year |
| 30-37% | Top-bracket, high-tax state (CA/NY) | 0.8-1.5% per year |
| 40%+ | Top bracket + ordinary-income offset usage | 1.5-2.5% per year |
3. Account type: is this a taxable account?
Direct indexing inside an IRA, 401(k), HSA, 529, or any other tax-advantaged wrapper does nothing. You can't harvest a loss in an IRA — the entire account is post-tax-treatment, so realizing losses is meaningless.
If your wealth is concentrated in retirement accounts, direct indexing has no benefit. Use a target-date fund and stop reading.
4. Time horizon: do you plan to hold 3+ years?
The tax alpha from harvesting is "deferred tax that compounds." The benefit comes from the compounding, not from a single year's savings. Across one or two years, you might harvest some losses but not have meaningful gains to offset them — the strategy doesn't pay off.
Across 5-10 years (and especially if you hold through death and get the §1014 step-up), the compounded tax alpha approaches its theoretical maximum. Direct indexing is a long-horizon strategy.
5. Operational fit: are you OK with 60 positions?
If looking at a 60-line portfolio statement gives you anxiety, direct indexing is going to make your investment relationship worse, not better. Some people genuinely prefer simpler portfolios and that preference is valid.
Software helps a lot here — modern direct-indexing tools surface the relevant changes, hide the noise, and let you treat the 60 positions as one sleeve from a UX perspective. But if you don't trust the software, the underlying complexity is real.
When direct indexing is wrong
Five disqualifiers. Any one is enough.
- Account too small. Below $50K, the per-position size is too small for harvesting to matter.
- Low or zero capital gains bracket. No tax to save, no alpha to capture.
- Tax-deferred wrapper. No realization events matter.
- Short time horizon. <3 years and you probably don't have time for the strategy to pay off.
- Hard preference for simplicity. The operational burden, even with software, will frustrate you.
When direct indexing is right
The clearest profile: $500K+ in a taxable brokerage, top federal bracket plus state tax, holding for at least 5 years, comfortable with software handling the 60 positions. For this profile, direct indexing is structurally better than a single ETF on every dimension that matters — cumulative tax savings, flexibility for future realizations, eventual step-up at death.
The break-even calculation in dollars: at $500K and a 30% combined LTCG rate, expected annual tax alpha is roughly $2,500- $5,000. At $1M, it's $5,000-$15,000. At $5M, it's $25,000-$75,000. These numbers easily cover any direct-indexing fee structure (robo at 0.25% AUM, software at flat subscription) and leave substantial savings on the table.
The 2026 honest take
Direct indexing isn't a magic strategy that beats the market. It's a structural way to capture tax savings that already exist in your portfolio but aren't being claimed by holding a single ETF. For the right account profile (high-bracket, taxable, $500K+, long horizon), the math is so favorable that not running direct indexing is a measurable mistake.
For the wrong profile (low-bracket, IRA-only, sub-$50K, short- horizon), it's a complication without a benefit.
If you're in between — $200K, mid-bracket, mostly taxable — try the math. Run the simulator on the TLH-101 page, see the numbers on your portfolio specifically. The decision should be based on those numbers, not on the brochure.
