Direct Indexing Is A Marketing Scheme

If you've talked to a wealth manager in the last two years, you've probably heard about direct indexing. It's been pitched as the next evolution of index investing — instead of owning an ETF, you own the individual stocks inside it, which supposedly lets you harvest tax losses stock-by-stock instead of fund-by-fund.

It sounds sophisticated. The marketing is polished. And for a very narrow slice of investors, it can genuinely help.

For most of my clients, it's not worth the complexity, the cost, or the time.

Here's what the actual research says.

The most rigorous academic study on this — Chaudhuri, Burnham, and Lo, published in the Financial Analysts Journal (2020) — looked at tax-loss harvesting on the 500 largest U.S. stocks from 1926 through 2018. Their headline number sounds impressive: 1.08% in annual "tax alpha."

But that number comes with an asterisk the marketing materials tend to skip. Once you account for the wash-sale rule — the requirement that you sit out of a position for 30 days after selling it at a loss — that benefit drops to about 0.82% per year. And that's still before real-world transaction costs and management fees eat into it further.

The Journal of Financial Planning has been even more direct about the gap between theory and practice. A 2025 piece in the journal put it plainly: most of the research promoting direct indexing's tax benefits is based on hypothetical portfolios, not real client accounts, and that's "a considerable red flag." The article identified three specific problems that rarely make it into the sales pitch:

1. Additions in perpetuity. Direct indexing's tax benefits depend on a steady stream of new cash coming into the account. Without fresh money, the stocks in the portfolio eventually all show gains instead of losses, and there's nothing left to harvest. The strategy quietly runs out of gas.
2. Tax loss decay. The best harvesting opportunities happen in year one, when your cost basis is freshest. After that, the well dries up fast — especially in a rising market, which is most markets, most of the time.
3. Portfolio lock. After a few good years, most of your positions are sitting on unrealized gains. At that point you're stuck holding individual stocks you can't sell without triggering the very tax bill you were trying to avoid. What started as a tax strategy becomes a portfolio you can't rebalance.

And then there's the operational reality.

Direct indexing isn't a "set it and forget it" strategy. It requires owning 60 to 100+ individual stocks, constant monitoring, and careful coordination across every account you hold — because if you harvest a loss in your taxable account and accidentally buy something "substantially identical" in your IRA within 30 days, the loss gets disallowed. For most business owners already juggling payroll, client work, and their own books, that's not a minor inconvenience — it's a second job.

Who it might actually make sense for:

To be fair to the strategy — because I want to give you the honest picture, not just the critical one — direct indexing has a real place for a specific type of investor: someone with a large taxable account (usually $1 million or more), recurring capital gains to offset (from a business sale, concentrated stock, or real estate), and a long time horizon where the account keeps growing with fresh contributions.

If that's not your situation — and for most of my clients, it isn't — a plain, low-cost index fund does close to the same job with a fraction of the complexity and none of the operational risk.

The bottom line: Tax alpha is real, but it's smaller, less durable, and far more fragile than the pitch decks suggest. Before you pay a premium for direct indexing, it's worth asking whether the juice is actually worth the squeeze — for your specific situation, not the hypothetical one in the marketing brochure.

FAQ: Is Direct Indexing Worth It?

1. What is direct indexing?

Direct indexing is an investment strategy where, instead of owning shares of an index fund or ETF, an investor directly owns the individual stocks that make up an index. This allows for tax-loss harvesting at the individual stock level rather than the fund level — selling specific underperforming stocks to realize losses while keeping the overall portfolio close to the index's performance.

2. How much tax benefit does direct indexing actually provide?

Research published in the Financial Analysts Journal (Chaudhuri, Burnham, and Lo, 2020) found tax-loss harvesting on the 500 largest U.S. stocks produced an average annual "tax alpha" of about 1.08% from 1926 through 2018. However, once the wash-sale rule is factored in — which requires sitting out of a position for 30 days after selling it at a loss — that benefit drops to roughly 0.82% per year, before accounting for real-world transaction costs and management fees.

3. Does direct indexing keep producing tax benefits every year?

Not indefinitely. The benefit tends to fade over time in a pattern researchers call "tax loss decay" — the best harvesting opportunities occur in the first year, while your cost basis is freshest, and shrink significantly after that, especially in a rising market. Without a steady stream of new cash being added to the account, the portfolio eventually accumulates mostly unrealized gains rather than losses, leaving little left to harvest.

4. What is "portfolio lock" in direct indexing?

Portfolio lock happens after a direct indexing account has grown for several years and most individual stock positions are sitting on unrealized gains. At that point, selling those positions to rebalance or simplify the portfolio would trigger the very capital gains tax bill the strategy was originally designed to avoid — effectively trapping the investor in a portfolio they can no longer easily adjust.

5. Is direct indexing more complicated to manage than a regular index fund?

Yes, significantly. Direct indexing typically involves owning 60 to 100+ individual stocks, which requires ongoing monitoring and careful coordination across every account an investor holds. This includes avoiding wash-sale violations — for example, harvesting a loss in a taxable account while inadvertently buying a "substantially identical" investment in an IRA within 30 days, which disallows the loss.

6. Who is direct indexing actually a good fit for?

Direct indexing tends to make the most sense for investors with a large taxable account — generally $1 million or more — who have recurring capital gains to offset, such as from a business sale, concentrated stock position, or real estate, and a long time horizon with ongoing new contributions to the account. Outside of that profile, a low-cost traditional index fund typically achieves a similar outcome with far less complexity and operational risk.

7. Is direct indexing better than a low-cost index fund for most investors?

For most individual investors, no. While the tax-loss harvesting benefit is real, it tends to be smaller, less durable, and more fragile than marketing materials typically suggest, and it fades over time. For investors without a large taxable account or ongoing capital gains to offset, a plain, low-cost index fund often delivers close to the same investment outcome without the added cost and complexity.

8. What did the Journal of Financial Planning say about direct indexing research?

A 2025 article in the Journal of Financial Planning noted that much of the research promoting direct indexing's tax benefits is based on hypothetical portfolios rather than real client accounts, calling this a "considerable red flag." The article specifically identified additions-in-perpetuity dependency, tax loss decay, and portfolio lock as problems that are often left out of sales pitches for the strategy.
