How This $150B+ Wall Street Strategy Could Lower Your Taxes | WSJ’s Take On the Week

Summary
Tax-aware long-short is presented as a souped-up version of tax-loss harvesting that combines direct indexing, leverage, and short selling to generate losses while still aiming for pre-tax alpha. Brent Sullivan explains the basic framework as a portfolio design problem: choose the investment, choose the account location, and time gains and losses so taxes are deferred rather than eliminated.
The strategy has grown to more than $150 billion in assets because it lets investors amplify exposure to managers they like and, in favorable market conditions, harvest more losses than a long-only portfolio. Sullivan argues that the tax benefit can be five to 10 times greater than typical tax-loss harvesting, but that benefit only matters if the manager can outperform enough to cover fees, financing costs, and trading friction.
The episode also emphasizes who the strategy fits. Sullivan says it is best suited to investors with high taxable income, concentrated stock positions, and real gains to offset, not simply high net worth. For most people, he recommends more basic tax housekeeping first: put tax-inefficient assets like bonds in tax-advantaged accounts and use Roth accounts for high-growth equity when appropriate.
Key takeaways
- Brent Sullivan says tax-aware long-short only makes sense if the manager can deliver enough pre-tax alpha to overcome fees, financing, and trading costs.
- He says the strategy’s tax benefit can be five to 10 times greater than a typical long-only tax-loss harvesting portfolio.
- Sullivan argues the best candidates are high-income investors with concentrated taxable positions, not just people with high net worth.
- He says the cheapest, highest-confidence tax moves are still basic asset-location decisions, like putting bonds in tax-advantaged accounts.
- Sullivan says advisors matter because they help manage access, leverage decisions, and the emotional volatility of the strategy.
Notable quotes
“tax-aware long short is really an extension or a combination of two different things”
“Now, what's new about tax-aware long short is that now we're injecting leverage into the portfolio”
“So, the first thing is just like does the alpha make sense? And this gives you leverage”
“those tax benefits can be you know, on the order of five to 10 times greater than a typical tax loss harvesting long only portfolio”
“the first gate in this decision is really the pre-tax alpha. So the alpha has to make sense before this strategy makes sense”
How the episode opens
Every time somebody rebalances for routine risk management, maybe they have lifestyle expenses, they're selling securities. Every single time that they do that, they're incurring capital gains. And so, is there a way to defer that capital gains bill?
And there is, using tax loss harvesting. And that's a simple strategy. We're just trying to net losses and gains.
And what that does is not eliminate the tax bill, it just pushes it into the future. And as you push it into the future, you can think about it as like a free loan from the government.

And one thing that you kept hearing about was uh something called uh a hot strategy.
Everyone was talking about it. It was being discussed water coolers around the tri-state area. Um and that was talking about tax efficiency, how to offset your gains that are going to be taxed.
And you were hearing about something called tax-aware investing, and specifically long-short tax-aware investing.
