White paper: Deleveraging long short direct indexing
10 min read
Tax-aware long short direct indexing strategies can provide investors with desired market exposures, allow them to express factor views, and deliver diversification and risk-control benefits while systematically managing taxes through loss harvesting and gain deferral. A frequent concern is what happens when an investor later wants to reduce leverage or exit the strategy because they no longer need accelerated loss generation and prefer a lower-fee direct indexing approach: Will deleveraging trigger substantial capital gains and a large tax event?
This white paper studies several practical deleveraging approaches and evaluates their potential tax impacts based on historical simulations. The approaches range from deleveraging immediately after running the strategy for a few years, once the investor’s factor view and incremental tax benefits are no longer needed, to gradually reducing leverage over time in a tax-aware manner that seeks to minimize tax impact. We present an estimated timeline for deleveraging with minimal tax impact, as well as the potential tax liability if an investor wishes to reduce leverage sooner. We also discuss an alternative decision some investors consider: contributing cash to close short positions early. Overall, our goal is to provide a structured, data-driven view of the main exit options for leveraged direct indexing strategies and the implications of each approach.
Key Takeaway: The optimal exit strategy depends on an investor’s timeline, available liquidity, and tax sensitivity. While immediate unwinds consume harvested losses, gradual tax-aware transitions or strategic cash contributions can significantly mitigate the tax burden of exiting the strategy.
Overview of the strategies and the deleveraging problem
Frec currently offers long short direct indexing strategies at three leverage levels: 140/40, 200/100, and 250/150. The numbers refer to the portfolio’s target equity exposures. For example, a 140/40 portfolio typically maintains about 140% long exposure and 40% short exposure, while the higher-leverage variants scale both the long and short extensions proportionally.
As the strategy runs, leverage is maintained near its target level, and ongoing tax-loss harvesting tends to shift the portfolio’s tax-lot profile over time. In an appreciating market, losses on the short extension are often realized, and positions are re-established, which can refresh cost basis and create recurring opportunities to harvest losses as prices move. Meanwhile, the long positions generally rise with the benchmark, and repeated harvesting and rebalancing can lower their cost basis over time, embedding larger unrealized gains even as the strategy continues to realize losses elsewhere.
When an investor later wants to reduce leverage, the portfolio needs to reduce both long and short exposures. Reducing short exposure typically means buying back short positions, while reducing long exposure means selling long holdings. In taxable accounts, selling long holdings can realize embedded gains and is often the primary driver of taxes during an unwind.
A tax-aware deleveraging program seeks to reduce leverage while minimizing tax liability by strategically selecting tax-efficient lots over time, such as closing high-cost-basis long positions with low embedded gains first. It can also allow an investor to reduce leverage without selling long positions by contributing additional cash to cover shorts. Throughout the process, the program aims to manage risk and maintain reasonable tracking to the benchmark.
Experiments and Results
In this white paper, we use quality-tilted long short direct indexing strategies benchmarked against the Russell 1000 as a representative example to study deleveraging in taxable accounts. The objective is to quantify how different deleveraging choices affect (1) the timeline for reducing leverage and (2) the associated tax impact.
We focus on the three leverage levels we currently offer: 140/40, 200/100, and 250/150. For each leverage level, we evaluate outcomes under multiple holding horizons before deleveraging. Specifically, we run each strategy with a $1M initial investment for 1, 3, and 5 years under its standard rebalancing process, with ongoing tax-loss harvesting and risk management designed to keep leverage near its target. The simulations are run over overlapping time periods, with each simulation starting once per year between April 1, 2005 and April 6, 2015, and using market, constituent, and risk data available through April 6, 2025.
After the initial run period, we examine three distinct deleveraging decisions that investors may consider.
Immediate deleveraging
First, we study an immediate deleveraging decision, where the investor chooses to reduce leverage to zero at the end of the initial run period. This approach provides a useful benchmark because it represents the fastest possible path to unlevered exposure. In a taxable account, however, reaching zero leverage typically requires meaningfully reduction of both the long and short extensions, and doing so may force the realization of embedded gains in the long extension. For each of the 1-, 3-, and 5-year run horizons, we estimate the resulting realized gains under this immediate deleveraging approach.
The figure below summarizes how much tax loss the strategies harvest during the initial holding period and how much of those losses would be consumed if an investor chooses to deleverage immediately at the end of that period. For each horizon (1, 3, and 5 years), the total height of each bar represents cumulative losses harvested as a percent of the initial investment. The lighter portion of each bar indicates the share of harvested losses that would be used up during an immediate deleveraging event, while the solid portion reflects the remaining net losses that are still available after deleveraging.
Immediate deleveraging can consume a meaningful fraction of harvested losses, especially after longer holding periods and at higher leverage levels. For example, running the 140/40 strategy for one year generates losses of roughly 26% of the initial investment, and deleveraging immediately after one year uses about 6% of those losses, leaving the investor with roughly 20% of net usable losses and a long-only portfolio thereafter. By contrast, running 250/150 for five years generates losses of roughly 190% of the initial investment on average, but deleveraging immediately consumes about 127%, leaving roughly 64% of net usable losses. Although a larger share of harvested losses may be used up when deleveraging higher-leverage strategies or after longer holding periods, the remaining net losses generally still increase with both leverage and time in the strategy.
Tax-aware deleveraging
Second, we study a tax-aware deleveraging approach designed to minimize tax impact. To model this, we assume the investor begins deleveraging at the end of the initial run period, but allows the portfolio to transition over an additional five years under a tax-aware deleveraging policy. The goal is to reduce gross exposure over time while avoiding unnecessary realization of gains. The implementation is intentionally opportunistic. When the portfolio has available loss positions, it can use those trades to fund exposure reductions without increasing net realized gains. When losses are scarce, the program may slow the pace of deleveraging rather than forcing large realized gains. This experiment produces an estimated deleveraging timeline for each leverage level and each initial run horizon, illustrating how quickly leverage can decline when the investor prioritizes minimizing taxes.
The figures below show the average deleveraging paths for 140/40, 200/100, and 250/150 after running each strategy for 1, 3, or 5 years, and then deleveraging under a tax-aware objective over the subsequent five years. The shaded region of each line represents the 25th–75th percentile range across simulations.
We observe the expected pattern: the longer the strategy is maintained at its target leverage before deleveraging begins, and the higher the leverage level, the longer it typically takes to unwind while minimizing realized gains.
After a 1-year initial run, deleveraging is fast across all three leverage levels. On average, 140/40 is reduced to near-zero leverage within about one year of beginning deleveraging, 200/100 reaches near-zero leverage within about three years, and 250/150 reaches low single-digit leverage within about four years. In practice, a shorter initial holding period generally allows the portfolio to unwind leverage more efficiently under a tax-aware approach.
After a 3-year initial run, the unwind remains steady but is meaningfully slower, especially at higher leverage. Measured from the start of deleveraging (end of year 3), 140/40 declines from its 40% target to 10.7% after one year of deleveraging (end of year 4) and to 3.1% after three years (end of year 6). Over the same timeline, 200/100 and 250/150 drop from 100% and 150% to 44.2% and 70.9% after one year, and then level off at 12.8% and 23.2% by the end of the five-year deleveraging window (end of year 8).
After a 5-year initial run, the gap is most pronounced. Starting deleveraging at the end of year 5, 140/40 falls from 40% to 17.1% after one year (end of year 6) and reaches 1.9% by the end of the five-year deleveraging window (end of year 10). In comparison, 200/100 declines from 100% to 57.7% after one year and to 19.6% by year 10, while 250/150 decreases from 150% to 88.1% after one year and to 34.2% by year 10.
Deleveraging by covering shorts with cash
Third, we evaluate an alternative decision some investors consider: contributing cash to close short positions early. This approach can reduce gross leverage without requiring the sale of long positions, which typically embed a lot of unrealized gains. Once the short positions are covered, the portfolio becomes fully deleveraged. To analyze it, we estimate the amount of cash required to buy back short positions based on the portfolio’s short-side market value and calculate unrealized gains or losses embedded in the short positions that we are closing. We then estimate the tax implications of covering those shorts, assuming a 42.8% short-term tax rate. This provides a practical estimate of total external liquidity that may be needed to fully deleverage the portfolio, taking the potential tax liability into consideration.
In the figures below, the total height of each bar represents the external cash required to fully deleverage the portfolio. The solid portion represents the cash needed to close the short positions, and the lighter portion represents the potential tax liability associated with covering those shorts.
Overall, the estimated tax liability is generally modest when an investor is able to contribute additional cash to close the short extension. On average, the largest tax liability occurs when running 250/150 for five years and immediately covering the short extension, which is initially about 150% of portfolio value; doing so results in an estimated tax liability of 8.6% of portfolio value. Under the tax-aware deleveraging approach, after five years of deleveraging the short exposure that needs to be covered declines to roughly 34% of portfolio value, and the estimated tax liability falls to 3.3%.
Conclusion
In this white paper, we explored tax-aware deleveraging options for investors who want to reduce leverage in long short direct indexing strategies without triggering a large, concentrated tax event. The feasibility and pace of tax-efficient deleveraging depend on market conditions and the portfolio’s tax-lot profile. In markets with frequent drawdowns and meaningful dispersion across names, loss opportunities are more likely to appear, which can make it easier to reduce leverage without increasing net realized gains. In persistent bull markets, losses may be scarce while embedded gains in the long sleeve continue to grow, making tax constraints more binding and potentially slowing the deleveraging process. We hope this white paper helps investors choose a leverage level and a deleveraging approach that align with their investment objectives and tax outlook.
