Direct indexing has emerged as a popular solution for taxable investors seeking greater customization and tax efficiency. By directly owning the underlying securities of an index, investors can tailor portfolios to their preferences and harvest losses at the individual security level. 

But while direct indexing offers notable advantages over traditional index funds, it still has structural limitations, especially when it comes to consistent tax-loss harvesting in rising equity markets. 

This article explores where direct indexing may fall short and how a tax-aware long/short overlay strategy may enhance its effectiveness, possibly offering investors an additional layer of flexibility and potential after-tax value. 

The Benefits & Boundaries of Direct Indexing 

We believe direct indexing allows investors to: 

• Replicate the performance of a broad index while owning the individual components 

• Customize holdings based on ESG screens, factor tilts, or concentrated positions 

• Harvest losses at the security level to offset capital gains in the portfolio 

While these benefits are real, loss harvesting is still limited to the long side of the market. When equity markets rise broadly, as they often do over long time periods, loss harvesting opportunities become scarce. Tax efficiency then becomes more scarce, waiting for volatility or downturns to unlock value.¹ 

Why Tax-Aware Overlays Add a Second Dimension 

A long/short overlay strategy can sit alongside a direct indexing portfolio as a market-neutral extension. Rather than replicating the index again, the overlay uses long and short positions across a separate portfolio to generate additional loss-harvesting opportunities. ² 

Key advantages include: 

• Short positions can harvest losses when markets rise. This adds a second source of tax-loss harvesting beyond long-side volatility.¹

• The overlay can operate independently of the index portfolio. It does not require changes to the core holdings in the direct indexing sleeve, provided wash sale rules are effectively managed. 

• Losses from the overlay can offset gains elsewhere. This includes gains from equity sales, appreciated concentrated stock position, real estate transactions, or private investments, subject to IRS rules. ²  

By combining the strengths of both strategies, investors can potentially build a more persistent tax management engine. 

Implementation: Designed to Work in Tandem 

The overlay is typically structured as a separately managed account (SMA) and may use existing assets as collateral, allowing it to operate without triggering sales in the core portfolio.³

The direct indexing portfolio continues to track the investor’s chosen benchmark (e.g., S&P 500 or MSCI World), while the overlay introduces offsetting exposures designed to remain market neutral.³

Together, we believe the two strategies aim to deliver: 

• Custom tracking of investor preferences 

• Greater surface area for tax-loss harvesting 

• Potential for improved tax efficiency without compromising long-term allocation 

It’s important to note that while the overlay does seek to track and index or deliver market “beta”, the direct indexing portfolio remains aligned with the investor’s chosen benchmark for market-like exposure.³ 

Risk Considerations 

When combining direct indexing with a tax-aware overlay, investors and advisors should coordinate around: 

1. Equity Risk: These strategies provide broad exposure to public equity markets. Equity markets can be volatile and subject to sudden fluctuations in value. Such fluctuations, often driven by macroeconomic factors like recessions, interest rate changes, and inflation, can result in significant losses. 

2. Tracking Error Risk: These strategies do not replicate an index perfectly, which may result in significant deviations and significant underperformance versus the target benchmark.  

3. Tax Risk: Loss harvesting capability will generally diminish with time. It may not be possible to defer capital gains indefinitely, to the extent there is a significant liquidity or rebalancing need from the portfolio. No amount of capital loss generation is guaranteed, and it may not be possible to fully offset other capital gains using this strategy, if those gains are sufficiently large and/or there is inadequate time to generate offsetting capital losses in a calendar year.

You are strongly encouraged to consult with qualified tax and/or legal counsel to evaluate the potential tax implications associated with this strategy. 

Conclusion 

Direct indexing is a valuable tax-aware tool for many investors. However, like all strategies, it has limits, particularly when markets rise, and long-only tax losses become scarce. 

Adding a long/short overlay may enhance the power of direct indexing by introducing a second, uncorrelated channel for loss harvesting. For taxable investors managing capital gains over multiple years, this combination may offer greater control, consistency, and coordination across the portfolio.

Equities 

• Interest Rate Risk: Higher interest rates may adversely impact equity valuations. 

• Macro Risk: Macro factors including interest rates, inflation, or economic growth may lead to materially different return outcomes for the sector, particularly if there is a material impact to earnings outlooks. 

• Mark to Market Risk: Equities are relatively volatile securities and may be especially volatile in a poor macro backdrop.
