Direct Indexing: Personalization and Tax-Loss Harvesting for Taxable Portfolios

Index funds and ETFs have made broad market investing simple and low cost. But when you own a fund, you own shares of the fund, not the individual stocks inside it. Direct indexing takes a different approach: you own the individual securities that make up an index in a separately managed account, which can open the door to personalization and more targeted tax management.

For investors with sizable taxable accounts, direct indexing can be a useful tool. It is not right for everyone, and its benefits depend heavily on your tax situation, your other holdings, and how the account is managed over time. Below, we explain how it works, where it may help, and the limits worth understanding.

Start Here: A Complimentary Wealth and Tax Review

Before changing how your portfolio is structured, it helps to see your investments and taxes side by side. Compound offers a complimentary, no-obligation wealth and tax review that may include:

  • Your taxable accounts: holdings, cost basis, unrealized gains, and concentration

  • Recent tax returns: realized gains, carryforward losses, and planning opportunities

  • Concentrated positions: company stock or legacy holdings you may want to diversify

  • Charitable and estate goals: how appreciated securities may fit into giving or legacy plans

  • Account structure: how taxable, tax-deferred, and Roth accounts work together

What Is Direct Indexing?

Direct indexing means buying many or all of the individual stocks in an index, such as a broad U.S. large company index, rather than buying a single fund that tracks it. The account is typically managed by an investment manager using software that keeps the portfolio close to the index while allowing adjustments.

Because you own each stock directly, each one has its own cost basis. That is what makes much of the tax management possible. Direct indexing is also called custom indexing, because the portfolio can be tailored in ways a pooled fund cannot.

How Does Custom Indexing Allow Personalization?

Custom indexing can be adjusted to fit your situation. Common examples include:

  • Excluding a concentrated holding. If you already own a large amount of your employer's stock, the account can exclude that company or sector to avoid adding more exposure.

  • Values-based preferences. Some investors choose to exclude certain industries or companies.

  • Gradual transition from legacy holdings. Existing stocks with large gains may be folded into the portfolio and sold over time rather than all at once.

  • Factor tilts. Some accounts tilt toward certain characteristics, such as dividends or company size.

Every customization moves the portfolio further from the index, which can cause returns to differ from the benchmark, sometimes meaningfully. This is called tracking error.

Tax Loss Harvesting With Direct Indexing

Tax-loss harvesting means selling an investment at a loss and using that loss to offset capital gains elsewhere. Within limits set by tax law, excess losses may offset some ordinary income, and unused losses can generally carry forward to future years.

With a single index fund, a harvesting opportunity exists only if the fund as a whole is down. With direct indexing, individual stocks move differently even in a rising market, so there may be more frequent opportunities to harvest losses on specific positions while keeping overall market exposure similar.

Tax loss harvesting with direct indexing may be most useful for investors who:

  • Expect meaningful capital gains from a business sale, real estate, or concentrated stock

  • Hold a large taxable account and are adding new money over time

  • Want to diversify out of appreciated positions over several years

Important Limits and Caveats

Direct indexing has real tradeoffs worth discussing before you begin:

  • Wash-sale rules. If you buy a substantially identical security within 30 days before or after selling it at a loss, the loss may be disallowed. This applies across all your accounts, including a spouse's accounts and IRAs, which requires coordination.

  • Harvesting tends to decline over time. As a portfolio rises, more positions carry gains and fewer offer losses. New contributions can extend opportunities, but the early years often produce most of the harvested losses.

  • Losses defer taxes, they do not erase them. Harvesting lowers your cost basis, which can mean larger gains when positions are eventually sold. The benefit depends on future tax rates, holding period, and whether assets are donated or passed to heirs.

  • Diversification considerations. A direct index holds many stocks, but customizations and exclusions can reduce diversification and increase tracking error. Diversification does not ensure a profit or protect against loss.

  • Costs and minimums. Separately managed accounts may have higher minimums and fees than index funds or ETFs.

  • Complexity. Hundreds of positions can mean longer tax statements and more recordkeeping.

How Direct Indexing Fits Wealth and Tax Planning

Direct indexing works best as part of a coordinated plan rather than as a standalone product. Harvested losses are most valuable when your tax advisor knows when gains are coming, and your investment strategy is most effective when it reflects your full balance sheet. That is the idea behind integrated tax and wealth management planning: wealth management and tax planning and preparation working from the same information.

Appreciated shares inside a direct index may also support charitable goals. Gifting long-held appreciated stock to a donor-advised fund, for example, may provide a deduction and avoid capital gains on the gifted shares.

Frequently Asked Questions

What is direct indexing?

Direct indexing is owning the individual stocks in an index, usually in a separately managed account, instead of owning a fund that tracks the index. It allows personalization and tax management at the individual stock level.

How does tax loss harvesting with direct indexing work?

Individual stocks that have declined can be sold to realize losses, then replaced with similar holdings to keep market exposure. Those losses may offset gains elsewhere, subject to wash-sale and other tax rules.

What is the difference between custom indexing and an index fund?

An index fund is a single pooled investment. Custom indexing holds the underlying stocks directly, so it can exclude companies, reflect preferences, and harvest losses on individual positions, though it may track the index less closely.

Who may benefit from direct indexing?

Investors with larger taxable accounts, expected capital gains, or concentrated positions may benefit most. It is usually less useful inside IRAs or other tax-advantaged accounts.

Does Compound work with clients outside of Wisconsin?

Compound serves clients throughout Wisconsin and in surrounding areas. Availability of investment advisory services in a given state may depend on registration requirements.
