Tax-loss harvesting beyond direct indexing.
Direct indexing harvests losses from individual stocks. Tax-Aware Long/Short goes further: systematic short positions generate loss opportunities that long-only portfolios structurally cannot.
How it works
Five stages. Continuous loss generation.
1
Construct
Long large-cap exposure (S&P 500). Short small-cap exposure (Russell 2000).
2
Generate alpha
Adjust short exposure to seek pre-tax alpha from the large-cap/small-cap spread.
3
Accumulate losses
Short positions continually generate realized losses as positions are rotated.
4
Harvest
Losses are harvested periodically and systematically.
5
Offset
Harvested losses offset capital gains or carry forward indefinitely.
This is a simplified illustration of the strategy mechanism. Actual execution involves additional complexity. Tax outcomes are not guaranteed and depend on individual circumstances. This is not tax advice.
The structural positioning
Long large-cap. Short small-cap. By design.
U.S. Large Caps (S&P 500)
Core exposure to established, highly liquid companies. This is the growth engine of the portfolio.
U.S. Small Caps (Russell 2000)
Short exposure generates loss opportunities while expressing a view on large-cap relative strength.
Relative, not directional
Not betting on market direction. Expressing a structured view on large vs. small cap.
Loss engine
Short positions are the mechanism for continuous loss generation. Long-only can't do this.
Macro-aware
Large-cap tends to outperform when capital becomes selective, providing a structural tailwind.
Beyond direct indexing
Why long-only loss harvesting has limits.
Direct indexing
Tax-Aware Long/Short
Comparisons between direct indexing and Tax-Aware Long/Short reflect general characteristics of each approach. "Direct indexing" refers to strategies that purchase individual index constituents for tax-loss harvesting purposes. Features, costs, and tax outcomes vary by provider and individual circumstances.
The statement that long/short approaches can generate more loss opportunities than long-only approaches is based on the structural mechanism of short positions (which can generate losses in both rising and falling markets) and is supported by academic research. It does not guarantee that Tax-Aware Long/Short will harvest more losses than any specific direct indexing provider in any given period.
Minimum investment comparisons reflect publicly available information as of March 2026 and may vary. The $20,000+ figure for direct indexing reflects typical minimums across major providers including Frec and Wealthfront. Actual minimums vary by provider.

Who this is for
Offset taxes from real-world events.
Selling stocks or RSUs
Harvested losses offset realized capital gains from stock sales.
Selling a business
Carry forward losses to reduce capital gains from a future business sale.
Selling real estate
Harvested losses can help reduce capital gains from property transactions.
Building a loss bank
No gains yet? Losses carry forward indefinitely. Start accumulating now.
◎
Start early. Tax losses carry forward indefinitely. The sooner you begin accumulating, the larger your loss bank when you need it.
Tax loss harvesting involves risks. The effectiveness depends on your entire tax and investment profile, including transactions outside this account. Unused losses may be carried forward indefinitely under current tax law, but tax regulations are subject to change. This is not tax advice. Consult your tax advisor regarding your particular circumstances.

Common questions
What is Tax-Aware Long/Short investing?
Tax-Aware Long/Short combines long market exposure with systematic short positions to create more opportunities for tax-loss harvesting while staying invested.
How is this different from direct indexing?
Direct indexing relies on long-only holdings and opportunistic loss harvesting. A tax-aware long/short approach introduces short positions, which can generate additional loss events beyond what long-only portfolios typically allow.
Does this strategy try to outperform the market?
No. The primary focus is on improving after-tax efficiency through systematic loss realization, not predicting markets.
What happens if I don’t have capital gains this year?
Unused tax losses may be carried forward indefinitely and applied against capital gains in future years.
Who should consider this strategy?
Tax-Aware Long/Short is designed for taxable investors with current or expected capital gains who want to be more intentional about managing after-tax outcomes as part of a long-term plan.
