Advisers Turn to Tax-Aware Long-Short Strategies for Concentrated Stock

Founders and technology executives often accumulate low-basis shares in a single company, leaving them exposed to concentration risk but reluctant to sell because of a potentially steep capital-gains bill. Tax-aware 130/30 strategies seek to address that problem by holding $130 of long positions and $30 of shorts for every $100 invested. The portfolio retains roughly $100 of net market exposure while harvesting losses that may offset gains realized as the concentrated holding is gradually sold.

As of July 24, 2026, investment-management platform Vise set a $250,000 minimum for its long-short direct-indexing strategy and said it could generate as much as 11 times the losses available through traditional tax-loss harvesting. Its calculator showed a hypothetical $1 million allocation to a 130/30 portfolio producing $463,000 of returns over five years. Advisers can adjust leverage, market assumptions and investment horizons, though the projections do not guarantee tax savings or investment performance.
