How Tax-Aware Long-Short Strategies Help Diversify Concentrated Stock
If you are an executive or founder, a concentrated stock position is often the result of success. It can reflect years of hard work, belief in your company and a compensation structure built around equity. Over time, that equity can grow into a significant portion of your net worth.
In many cases, the good news is that some of your investments have appreciated significantly. The challenge is that a large share of your wealth may now be concentrated in just a few holdings. What once felt like upside potential can begin to feel like too much risk with a massive tax burden.
Then, a big question surfaces: how do you reduce risk and diversify a concentrated stock position without triggering a substantial capital gains tax bill?
Selling shares may be financially prudent, but stomaching the large tax bill could be painful. This tension between diversification and taxation is one of the most common planning challenges we see among equity-compensated professionals like you. It is rarely just a technical question. It is about protecting what you have built while positioning your wealth for the future.
Tax-aware long-short strategies have gained attention as one effective tool for navigating this challenge. Under the right circumstances, these strategies can be a powerful way to diversify concentrated wealth while managing the timing of capital gains.
Because these strategies can be complex, explanations you find online may not always capture the full picture. Determining whether they make sense often requires evaluating them alongside your tax situation, liquidity needs and long-term financial goals. In many cases, that kind of evaluation is best done in conversation with an experienced team of financial advisors.
The challenge of concentrated stock positions and capital gains
Concentrated stock positions can happen gradually as one investment grows to represent a significant share of an investor’s overall wealth. Over time, a founder may build a company that becomes a meaningful source of personal wealth. An executive may accumulate years of equity compensation. Or a long-held investment simply performs far better than expected. However it happens, one holding can gradually grow to represent a significant share of your net worth.
That kind of success can feel rewarding, but it can also create a new layer of complexity. When a large portion of your portfolio depends on the fortunes of a single company, market swings can have a much greater impact on your overall financial picture.
Diversifying can help reduce that exposure. The challenge is that selling highly appreciated shares may also trigger a substantial capital gains tax bill.
This is where many investors find themselves caught between two reasonable instincts. Holding the position may begin to feel increasingly risky, while selling it can feel unnecessarily costly.
As a result, many executives and entrepreneurs begin exploring ways to diversify gradually while managing the potential tax consequences along the way.
One sophisticated tool: Tax-aware long-short strategies
One strategy that has gained attention in recent years is the use of tax-aware long-short portfolios. These strategies build on the traditional tax-loss-harvesting methods used for many years in direct indexing strategies.
Historically, these approaches were primarily available to institutional investors and ultra-high-net-worth families. Over time, advances in trading technology and portfolio construction have made some versions more accessible to a broader group of investors.
Today, several investment managers offer tax-aware long-short strategies designed specifically to help investors diversify highly appreciated stock positions. Some of the best-known strategies in this space have been developed by firms such as AQR and Quantinno, along with other institutional asset managers focused on tax-aware portfolio construction.
Even so, these remain sophisticated tools. They are typically used as one component of a broader investment strategy rather than as a complete portfolio solution.
At their core, tax-aware long-short strategies aim to provide a tax-efficient investment return by generating capital losses within a diversified investment portfolio. Those losses may help offset gains realized when selling appreciated holdings, allowing investors to shift from a single concentrated position into a broader mix of investments.
The goal is not to eliminate taxes permanently.
Instead, these strategies are designed to help manage the timing of capital gains while allowing portfolios to become more diversified.
Instead, these strategies are designed to help manage the timing of capital gains while allowing portfolios to become more diversified.
Our team regularly evaluates and implements strategies like these for individuals and families with concentrated wealth, particularly executives and entrepreneurs whose financial lives are closely tied to equity compensation. As with any sophisticated strategy, it’s important to discuss how it may fit within your broader financial plan with an experienced wealth manager or financial advisor.
Tax-aware long-short strategy: How it works
At a high level, the goal is to implement an effective investment strategy that can also help offset some of the capital gains that may arise when you sell a concentrated stock position. The strategy does this by creating opportunities for capital losses within a diversified investment portfolio through an ongoing tax-loss harvesting process.
A simplified version of how this process may work is shown below:
| Step | What happens |
| 1. Sell concentrated stock | Creates capital gains |
| 2. Invest in a tax-aware long-short portfolio | Portfolio may generate both gains and losses |
| 3. Realize losses within the portfolio | Losses may offset gains from the stock sale |
| 4. Result | A more diversified portfolio and the potential to defer some taxes |
Using tax-loss harvesting to offset gains
The basic premise is straightforward. When you sell an investment for a gain, taxes are typically due unless you also have capital losses from other transactions in the same tax year that can offset that gain.
Tax-aware long-short portfolios are designed to create opportunities for those losses. By holding positions on both sides of the market, the portfolio can generate gains and losses whether markets rise or fall.
In this context, the term “long” simply means owning shares of a company and benefiting when the share price rises. “Short” refers to selling shares you do not currently own in order to benefit if the share price declines. These terms describe how the positions behave, not how long they are held. The investment manager is making decisions to buy long stock in companies they expect to outperform and look to sell short companies they expect to underperform. In most strategies, investors can typically exit the portfolio without long lock-up periods.
Because the portfolio includes both long and short positions, it increases the opportunity to generate gains and losses regardless of which way the markets move.
In practical terms, a highly appreciated, concentrated holding can be sold and the exposure transferred into a much broader and more diversified set of positions. The capital gains tax is not eliminated, but it may be deferred until those new holdings are eventually sold.
In some cases, investors hold highly appreciated assets for many years because assets passed to heirs may receive a step-up in cost basis at death, potentially reducing capital gains taxes for the next generation. However, many investors prefer to diversify concentrated positions during their lifetime rather than maintain significant exposure to a single stock. Strategies like tax-aware long-short portfolios can provide one way to reduce that concentration while managing the timing of the associated tax consequences.
Implementation considerations and tax rules
Long-short strategies are entirely legal and have been used for many years. Advances in trading technology have significantly reduced transaction costs, which has helped make these strategies more accessible to a broader group of investors.
Another feature is that income from many of these accounts is reported on IRS Form 1099, just like any other brokerage account. The amount of trading and different types of income and expenses can make the Form 1099 more complex than a traditional brokerage account. However, they are far more straightforward and can simplify tax reporting compared with some hedge fund structures that issue Schedule K-1 filings, which are often delivered later in the tax season and may require investors to extend their returns.
Of note, the IRS has rules to watch for in setting up these accounts:
- First, selling a stock at a loss and buying the same one within 30 days is called a wash sale. This wipes out the favorable tax treatment that is core to the strategy.
- You also need to be careful that you don’t short a stock that you own long in a different account. This falls under the constructive sale rules which would trigger the gain on the shares you own.
As a result, long-short investors need to be mindful of all relevant transactions and shares they own in all their taxable accounts or set up rules to avoid conflicting trades. All in, be careful using these accounts if you own individual stocks in a different account.
Advanced planning: Using prepaid variable forwards (PVFs)
In some situations, investors may want to diversify without selling shares immediately in order to maintain some participation in the stock’s potential upside. In cases like this, more advanced planning tools may come into play.
For example, a prepaid variable forward (PVF) contract—sometimes called a variable prepaid forward (VPF)—may be used alongside diversification strategies.
These contracts can help limit downside risk in a concentrated stock position while also providing liquidity. A PVF typically establishes a “floor price” on the stock and provides a loan based on that value. In exchange, a “ceiling price” is set, meaning the investor participates in the stock’s upside only up to that level.
The loan from the PVF—often referred to as the upfront credit—can then be used to fund a diversification strategy such as a tax-aware long-short portfolio designed to harvest losses over time. Used together, these strategies may help manage the tax consequences of diversifying a concentrated position while reducing exposure to a single stock.
Because these structures are complex and must comply with specific tax rules, implementing them requires careful coordination with experienced financial and tax advisors.
It is important to remember that these strategies generally defer taxes rather than eliminate them. If positions within the portfolio are eventually sold without additional planning, gains may still be realized. For this reason, long-short strategies are typically most effective when implemented as part of a broader, long-term tax and diversification plan.
| When it may make sense | Where it may fall short |
Tax-aware long-short strategies may be worth exploring if you:
These strategies tend to work best when investors have a longer time horizon and do not need immediate liquidity from the concentrated position. Real-World Example We often work with executives whose equity compensation has grown into several million dollars of highly appreciated stock concentrated in one or two companies. After a period of market volatility, they may want to reduce that concentration but hesitate to sell because doing so could trigger a significant capital gains tax bill. In situations like this, a tax-aware long-short strategy may help diversify a portion of the position while managing the timing of taxes. |
Like any sophisticated investment strategy, tax-aware long-short portfolios involve trade-offs. Some considerations may include:

How it fits into a broader diversification plan
Tax-aware long-short strategies can be a helpful tool if you are managing a concentrated stock position. But they are rarely the only tool. Other approaches may include direct indexing strategies, exchange funds, options-based hedging techniques or estate planning strategies such as charitable giving or family gifting. The right mix depends on your goals, your time horizon and your tax situation.
In our experience, conversations about investing often include what might be called the strategy of the moment. Certain tools become widely discussed for a period of time. They show up in articles, at conferences and sometimes even in “cocktail party talk.”
Those strategies can certainly have value. But like many sophisticated approaches, the question is often not simply whether a strategy works. The more important question is whether it fits within your broader long-term plan.
That is where thoughtful planning comes in. Diversifying concentrated wealth often involves combining several strategies over time rather than relying on a single solution. The objective is not simply to reduce taxes in a given year. It is to help protect what you have built and position that wealth to support the people and priorities that matter most to you.
As a firm that is 100% employee-owned, that long-term perspective is central to how we approach this work. The people advising you today are invested in the future of the firm and in the relationships we build with individuals and families across generations.
Frequently asked questions about tax-aware long-short strategiesWhat is a tax-aware long-short strategy?A tax-aware long-short strategy is an investment approach designed to help you invest in the market with a diversified portfolio while using tax-loss-harvesting to manage the tax impact of selling highly appreciated assets. The portfolio typically holds both long positions, which may benefit when stock prices rise, and short positions, which may benefit when prices fall. Because the strategy operates on both sides of the market, it may generate capital losses that can offset gains from the sale of your concentrated stock no matter which direction markets move. This may allow you to diversify your portfolio while managing the timing of capital gains taxes. It is important to note that these strategies generally defer taxes rather than eliminate them. Can I diversify concentrated stock without paying capital gains right away?In many cases, you cannot completely avoid capital gains taxes when selling highly appreciated stock. However, certain strategies may help manage when those taxes are recognized. Tax-aware long-short strategies attempt to provide market returns while using tax-loss-harvesting to generate capital losses within a diversified portfolio. Those losses may offset gains from selling your concentrated positions, which may allow you to defer some of the tax impact while diversifying your holdings. Other approaches may include direct indexing strategies, exchange funds, options-based strategies or charitable planning techniques. Who might benefit from a tax-aware long-short strategy?You may consider this type of strategy if you hold large, highly appreciated assets in taxable accounts and want to diversify without the tax consequences of realizing all gains in the same year. These strategies are often used by executives, founders and professionals whose wealth includes concentrated stock positions. Because of minimum investment requirements and strategy complexity, they are typically most appropriate for larger portfolios and are usually implemented as part of a broader wealth plan. How much do tax-aware long-short strategies typically require to invest?Minimum investments vary depending on the manager and the strategy. Some domestic strategies may require approximately $1 million, while global strategies often have higher minimums. In most cases, these strategies are implemented as one component of a diversified portfolio rather than as a standalone investment. Are tax-aware long-short strategies similar to hedge funds?Tax-aware long-short strategies use some techniques that have historically been associated with hedge funds, such as holding both long and short positions in stocks. However, many modern strategies are designed to be more accessible and transparent than traditional hedge fund structures. Some report tax information on IRS Form 1099 rather than Schedule K-1 filings, which may simplify tax reporting for you. Even so, these strategies remain sophisticated investment tools and are typically implemented within a broader portfolio strategy. What are the risks of tax-aware long-short strategies?Like any investment strategy, tax-aware long-short portfolios involve trade-offs. These strategies often have higher costs than traditional long-only investments. Performance may also differ from broad market benchmarks because the strategy relies on active stock selection. Shorting stocks has unique risks many investors are unfamiliar with, such as utilizing leverage in a balanced approach. For this reason, it is important to utilize managers with meaningful experience navigating these risks. In addition, the tax benefits you experience will depend on how the strategy performs and how the portfolio is managed over time. What happens to the taxes later if I use a tax-aware long-short strategy?Tax-aware long-short strategies generally defer capital gains rather than eliminate them. If losses generated within the portfolio offset gains from selling appreciated assets, the tax liability may be postponed. However, when positions within the long-short portfolio are eventually sold, gains may still be realized. For this reason, it is important to consider how the strategy fits within your broader financial plan, which may include charitable strategies, estate planning or other tax management approaches. Can tax-aware long-short strategies offset salary or bonus income?Generally, no. Losses generated within tax-aware long-short portfolios are typically used to offset capital gains. They usually cannot be used to offset ordinary income such as salary or bonuses. If you are interested in strategies that address different types of income, it may be helpful to discuss your options with your financial and tax advisors. |
