Direct Indexing: The Future of Personalised Investing

For decades, index investing meant buying a fund — an ETF or mutual fund that owned the underlying securities on your behalf. The fund pooled thousands of investors' capital and tracked an index like the S&P 500 or MSCI World. This approach remains highly effective for most investors, but it has inherent limitations: you cannot customise the underlying holdings, you cannot harvest tax losses on individual securities, and you share the fund's cost basis and tax history with all other investors.

Direct indexing — owning the individual stocks that comprise an index in your own account, rather than through a pooled fund — overcomes these limitations. Until recently, the transaction costs of buying hundreds of individual stocks made this approach practical only for ultra-high-net-worth investors. The advent of fractional shares, zero-commission trading, and sophisticated portfolio management technology has made direct indexing accessible to a much broader range of investors, with minimum thresholds falling from USD 10 million to USD 100,000 or even less at some providers.

This guide explains how direct indexing works, who benefits most from it, the main use cases, what to look for in a provider, and the practical considerations for internationally mobile investors.

How Direct Indexing Works

Rather than buying a single fund that tracks the S&P 500, for example, a direct indexing client receives a separately managed account (SMA) containing the actual shares of each of the 500 companies, weighted roughly in proportion to the index. The investor legally owns each stock individually, as a direct beneficial owner.

The portfolio management system continuously monitors the portfolio and rebalances it as the index changes — when stocks enter or leave the index, when weights drift due to price movements, or when dividends are received.

The critical difference from fund ownership is that because the investor owns each stock individually, they can:

1. Harvest tax losses on individual securities without exiting the overall index exposure
2. Exclude specific stocks or sectors (for ESG, ethical, or concentration risk reasons)
3. Customise factor tilts (overweighting quality, value, or low-volatility characteristics)
4. Integrate concentrated stock positions from employer equity compensation without duplicating exposure

Tax-Loss Harvesting: The Core Advantage

The most compelling financial benefit of direct indexing for most investors is systematic tax-loss harvesting at the individual security level.

Even in a rising market, some individual stocks within an index will fall in value at any given time. In a pooled ETF, those embedded losses are invisible to you as an investor — they sit within the fund and can only be crystallised when the ETF itself is sold. In a direct index portfolio, the manager can sell the individual stocks that have fallen, crystallise a capital loss for tax purposes, and immediately replace them with similar (but not identical) stocks to maintain the portfolio's market exposure. This keeps the portfolio tracking the index while generating tax losses that can offset gains elsewhere.

Over a long investment horizon, the compounding benefit of systematic tax-loss harvesting can be significant. Academic research and provider analysis have estimated that harvesting can generate 0.5–1.5% of additional annual after-tax return, depending on market volatility, tax rates, the investor's other capital gains, and the portfolio's size.

For international investors, the benefit depends critically on the tax regime they are subject to. In jurisdictions with high capital gains tax rates — including the UK (up to 24% for higher-rate taxpayers as of 2026), Australia, Canada, and certain US states — the value of harvested losses is higher. In jurisdictions with low or zero capital gains taxes (UAE, Singapore, Hong Kong, Qatar), tax-loss harvesting provides no benefit.

Wash-sale rules in the US (which disallow losses if a substantially identical security is purchased within 30 days) must be carefully managed. Direct indexing systems replace sold securities with similar but distinct securities — different stocks in the same sector or industry — to avoid wash-sale violations. Professional management and specialist tax advice are essential for US persons or those with US tax obligations.

ESG and Ethical Customisation

A growing proportion of direct indexing clients use the approach to build a portfolio aligned with their personal values, religious beliefs, or institutional mandates — without sacrificing the core benefit of broad market exposure.

Common customisation requests include:

• ESG screening: Excluding companies failing specific environmental, social, or governance criteria
• Sector exclusion: Removing tobacco, weapons, gambling, alcohol, or fossil fuel companies
• Religious screens: Excluding interest-bearing instruments (Shariah-compliant screens) or other religiously prohibited activities
• Controversy-based exclusion: Removing specific companies involved in legal disputes, environmental disasters, or governance failures
• Custom ESG weighting: Overweighting companies with the strongest ESG ratings rather than simply excluding the worst

The key advantage over ESG ETFs is precision. Most ESG funds use broad sector exclusions or ESG data providers' ratings, which may not align with a specific investor's views. Direct indexing allows the investor to define exactly which companies to exclude and why — then implement that policy consistently across their portfolio.

A wealth manager advising a family that owns a pharmaceutical company, for example, can exclude all pharmaceutical competitors from the index portfolio to avoid doubling up on sector risk. A client with strong views on a specific controversy can exclude a single company without affecting the rest of the portfolio.

Concentrated Stock Management

Many HNW investors — particularly entrepreneurs, executives, and professionals who have received significant equity compensation — hold large, concentrated positions in one or a few stocks, often with a very low cost basis accumulated over many years. Selling to diversify creates an immediate, potentially large capital gains tax liability.

Direct indexing can address this through several techniques:

Tax-aware diversification: Rather than selling the concentrated position all at once, the direct indexing portfolio manager harvests losses from other positions to offset the gains from gradually selling down the concentrated stock. This spreads the tax liability over time and reduces the immediate cost of diversification.

Completion portfolios: A directly indexed "completion" portfolio holds all the stocks in the index except those that overlap with the concentrated holding, matching the investor's market exposure while the concentrated position is gradually reduced. This ensures broad diversification without doubling the position in the concentrated company.

Exchange funds (US only): Certain US structures allow investors to contribute a concentrated stock to a partnership and receive a diversified portfolio of other contributed stocks in return, deferring the capital gain. Direct indexing often complements exchange fund strategies.

Factor Customisation

Beyond ESG and tax, direct indexing allows investors to tilt their portfolio towards systematic factors — value, quality, momentum, low volatility — with greater precision than available through smart beta ETFs.

A client who wants 80% exposure to the MSCI World index characteristics but a 20% tilt towards quality stocks (based on a specific definition of quality they or their adviser have agreed) can implement this precisely in a direct index portfolio. The system continuously maintains both the index exposure and the factor tilt as markets move.

Who Benefits Most from Direct Indexing?

Not every investor needs direct indexing. A simple global equity ETF costing 0.10–0.20% per annum remains highly attractive for many investors, particularly those:

• In a tax-sheltered account (pension, ISA, or offshore bond) where tax-loss harvesting has no value
• In low or zero capital gains tax jurisdictions
• Investing relatively modest amounts (below USD 250,000–500,000) where the additional management costs eat into benefits
• With no concentrated stock positions to manage
• Without specific ESG or exclusion requirements

Direct indexing typically makes strongest financial sense for investors who:

• Have significant capital gains to offset each year
• Are subject to meaningful capital gains tax rates
• Hold or are accumulating concentrated stock positions
• Have strong views on specific exclusions or customisations
• Are investing USD 500,000 or more in a taxable account

Provider Landscape

The direct indexing industry has grown rapidly, with major providers now including Parametric Portfolio Associates (owned by Morgan Stanley), Aperio (owned by BlackRock), Natixis Portfolio Solutions, and numerous independent registered investment advisers in the US. Several robo-advisory platforms now offer direct indexing at lower thresholds, including Wealthfront, Betterment, and Fidelity.

In Europe, the direct indexing market is less mature, but several wealth managers and private banks offer equivalent customised SMA services for large minimum investments.

When evaluating providers, consider:

• Minimum investment: Ranges from USD 100,000 to USD 5 million or more
• Annual management fee: Typically 0.20–0.50% for the direct indexing overlay, plus any advisory fee
• Tax-loss harvesting methodology: How frequently does the system review for harvesting opportunities? How are wash-sale rules managed?
• Customisation flexibility: Can the client define specific exclusions? How are factor tilts implemented?
• Index tracking quality: How closely does the portfolio track the target index after customisations?
• Technology and reporting: Can you see each individual holding and the tax lot detail? Is reporting clear and accessible?

International Considerations

For internationally mobile investors, direct indexing introduces complexities that do not affect US-based investors:

Tax residency: The tax value of loss harvesting depends entirely on your current and future tax residency. If you are planning to move from a high-tax jurisdiction to a zero-capital-gains jurisdiction (such as UAE or Singapore), harvesting losses before the move may be less valuable than simply waiting until after the move to sell. Conversely, crystallising gains before a move to a high-tax country makes sense.

US withholding taxes: For non-US investors holding individual US stocks through a direct index portfolio, dividend withholding taxes apply (typically 15–30%, depending on applicable tax treaties). A US equity ETF domiciled in Ireland typically has a more favourable withholding arrangement under the Ireland-US tax treaty (15%). For very large portfolios, the direct tax may still be worthwhile, but this should be modelled carefully.

Reporting complexity: Owning hundreds of individual stocks in multiple jurisdictions increases tax reporting complexity. Annual declarations may include hundreds of dividend items and capital gain/loss calculations. Ensure the provider's reporting functionality meets your jurisdictional requirements.

PFIC considerations for US persons: US persons investing in non-US direct index programmes should take advice on whether any of the individual securities or the account structure itself could give rise to PFIC issues.

Direct Indexing vs ETF: An Honest Comparison

Direct indexing is not universally superior to ETF investing. The comparison depends on individual circumstances:

Feature	ETF	Direct Index
Annual cost	0.05–0.20%	0.25–0.60%
Tax-loss harvesting	Only at fund level	Individual stock level
ESG customisation	Limited	Highly flexible
Concentrated stock integration	Not possible	Yes
Tax reporting complexity	Low	High
Minimum investment	Any amount	USD 100K+
Suitable for tax-sheltered accounts	Yes	Little advantage

How Global Investments Can Help

Direct indexing represents a genuine evolution in personalised wealth management — but it is a tool that delivers its benefits only when properly implemented and integrated within a broader tax-planning framework. The wrong implementation in the wrong tax jurisdiction can add cost and complexity without meaningful benefit.

At Global Investments, we advise internationally mobile HNW clients on whether direct indexing makes sense for their specific circumstances, which providers offer the best combination of cost and functionality for non-US investors, and how to integrate direct indexing with concentrated stock management, pension strategy, and cross-border tax planning.
