Tax-Aware Long-Short Strategy Assets Surge to More Than $170 Billion From $2 Billion in 2022

Wealthy investors are pouring billions of dollars into a new tax-saving strategy. Total assets invested in so-called tax-aware long-short strategies, or TALS, have risen from $2 billion in 2022 to more than $170 billion. The strategy seeks to track a stock index while generating tax losses that can offset capital gains taxes. TALS products and their variants have grown rapidly among affluent investors.

Company owners selling their businesses and executives holding concentrated stock positions have also entered these products. A surge in initial public offerings, with many employees holding appreciated shares, has further increased demand for products that can offset large realized gains. For the wealth management industry, tax-aware products have become a business, with complex long-short strategies charging higher fees and attracting new clients.

In the case of a $1 million portfolio, a tax-aware long-short strategy can generate $250,000 in capital losses in the first year, declining in subsequent years. For a California investor, if those losses offset short-term capital gains, the tax value of a $250,000 loss is up to $137,500. These strategies offset gains on leveraged long positions with losses on leveraged short positions during the investment period. Investors who donate appreciated stock to charities or certain trusts do not need to realize gains and can therefore still benefit; some investors rely on a step-up in basis at death to eliminate taxes.

In early summer 2026, US Treasury officials warned at a seminar about "aggressive planning" involving investment products that offer tax losses. They did not name tax-aware long-short strategies but mentioned similar "tax alpha" products such as 351 conversions, box spread ETFs and other loss-generating funds. The Treasury officials said they would not let complex abusive tax structures become a runaway train. The officials did not say these practices are illegal and are currently seeking more information and comments. The surge in assets has also drawn scrutiny from tax authorities.

The most popular strategy involves a 130/30 ratio, in which $30 is borrowed against a $100 investment to add long positions and another $30 is borrowed for short positions; some funds sell 150/50 products or higher ratios. The tax benefits can partly offset this performance gap.

During 2025 and 2026, financing fees or spreads widened for many tax-aware long-short clients as lenders demanded more compensation for risk. The stacked fees generate revenue for registered investment advisers, lenders and managers.
