Stock Gains Without All the Taxes? How the Hottest Trade on Wall Street Works

With the U.S. stock market near record highs, wealthy investors and advisers are increasingly using leveraged tax-loss-harvesting strategies to create losses that offset capital gains while maintaining market exposure. Traditional direct indexing holds about $1.1 trillion but is producing fewer loss opportunities in this rally, so over $150 billion has flowed into newer “long-short tax-aware” or “tax-aware alpha” products. The shift reflects demand from investors sitting on concentrated gains in big tech and index funds and could influence portfolio construction and trading flows as managers deploy leverage to engineer tax outcomes. The trend raises questions about complexity, costs and risk from leverage even as it aims to boost after-tax returns.
