In a year that started with volatility, direct indexing had ample opportunity to take advantage of loss harvesting opportunities. 



Two kinds of volatility in the first quarter


We saw two very different kinds of volatility: Sideways markets and high stock-specific volatility in the first two months of 2026 gave way to broad market volatility in March after the US launched an offensive on Iran on February 28. The S&P 500® Index fell 4.33% in Q1 2026, and March’s -4.98% return drove most of that decline.


Looking by sector, Information Technology, which makes up more than 30% of the index, dragged down returns with a -9.13% result. In contrast, the Energy sector, at only 4% of the index, jumped 38% as the Iran conflict triggered dramatic increases in oil prices. Defensive sectors like Utilities, Consumer Staples and Materials also rose for the quarter, while Financials and Consumer Discretionary posted negative returns.


The war in Iran drove March volatility, and the markets moved daily in tandem with President Trump’s statements. Meanwhile, short-term inflation concerns rose, and the US Federal Reserve kept interest rates steady at the March meeting.

Opportunities abound to reduce taxes, regardless of market conditions

Driving strong loss harvesting


The first quarter presented robust tax loss harvesting opportunities as the CBOE Volatility Index (VIX) climbed into the thirties in March. Notably, the S&P 500 Index traded in a tight range to start the year, yet individual stock volatility reached a record high at roughly seven times that of the broader index. Overall, 55% of index constituents declined for the quarter, with an average loss of -12.84%, and nearly 30% fell more than 10%, with an average loss of -19.39%.


For the quarter, Parametric’s systematic loss harvesting approach realized more than $3.9 billion in losses across nearly 360,000 trades and delivered a potential tax benefit1 of almost $1.5 billion to Custom Core investors. Nearly half of the quarter’s harvested losses—$1.9 billion—were delivered in March alone.2


The bottom line


Q1’s mixed volatility created broad, repeatable opportunities to harvest losses in direct indexing portfolios, even as headlines drove sharp market swings. Parametric’s systematic approach helped investors capture those losses at scale, translating market dispersion into meaningful potential tax benefits. As volatility persists, disciplined tax management may help investors stay invested while potentially improving after-tax outcomes over time.



1 The potential tax benefit is calculated by applying the maximum federal rates for short-term and long-term capital gains, which are currently 40.8% and 23.8%, respectively. Quantifying the tax benefit of harvested losses assumes the taxpayer has sufficient long-term and short-term capital gains to use the harvested losses against.
