Why Tax Alpha Beats Stock Picking
How I Invest With David Weisburd

Summary
Tax-aware investing is becoming more important because investors are sitting on gains and looking for ways to reduce friction without changing their long-term objectives. Brent Sullivan argues that tax management matters across wealth levels, from high-net-worth families doing intergenerational planning to retirees managing IRMAA, Roth conversions, and capital gains. His core point is that for many taxable investors, tax alpha can matter more than trying to squeeze a little more return from stock picking.
A major theme is the evolution of tax-loss harvesting from simple long-only portfolios into long-short structures that create recurring loss realization opportunities. Brent says these products have grown quickly, with roughly $150 billion now in private wealth allocated to them, and he emphasizes that the tax benefits come from taking real risk, especially short exposure. He also argues that tracking error is not inherently bad; for active managers, it is often the mechanism by which their view shows up in the portfolio.
The discussion also covers trader funds, which can make fees deductible and generate ordinary losses, but come with limits such as basis, at-risk rules, and excess business loss caps. Brent repeatedly stresses that these strategies are expensive and operationally complex, so investors need competent managers, realistic expectations, and a willingness to stay invested for years.
Key takeaways
- Brent Sullivan says tax-aware investing matters for every wealth bracket, not just ultra-high-net-worth families, because the right toolkit can address gains, retirement, and intergenerational planning.
- He estimates about $150 billion is now allocated to long-short tax-loss harvesting strategies, up from roughly $10 billion to $20 billion two years ago.
- Brent argues that tracking error is often a feature of active long-short management, because it reflects the manager’s view and risk-taking rather than a defect.
- He says trader funds can create deductible fees and ordinary losses, but those benefits are limited by basis, at-risk rules, and excess business loss constraints.
- Brent warns that all of these strategies require meaningful costs, operational discipline, and a manager who can actually generate pre-tax alpha.
Notable quotes
“tax management as a good fit for those types of people. And the reason is it is so mechanical. It's so boring”
“Tax benefits emerge from taking risk. When you don't take risk, that's when there's like a really a big tax issue to be mindful of”
“they all manage portfolios differently. Some really really lean into their active differentiators. Some are closer to the benchmark”
“management fees become deductible, and the second one is that everything gets marked to market and treated as ordinary”
How the episode opens
And so you run the largest Substack on the topic of tax alpha and tax-aware investing. Take a step back. Why has tax-aware investing become so topical today?
Well, this always happens when there's a bull market and we've got, you know, what, a decade plus of stocks essentially going up. And so folks are looking for ways to minimize friction in their portfolios with just routine rebalancing. Maybe they've had a successful outcome, private or public, and now they're just looking for ways to manage risk.
And one of the key areas to manage risk is taxation. And so if they can eliminate that or defer taxation, then there's just a chance that they can keep their portfolio aligned with their long-term objectives. And who is tax-aware investing relevant to?
Is it just people with very large capital gains? Is it just the ultra-high net worth? Or is this just something that's more relevant to people?
I I think there's something in this for every strata of wealth. You know, the highest highest net worth, I mean, we're talking about intergenerational planning. If we come back from that down a you know, a level or two, we're talking about really income income management, capital gains management, lifestyle, maybe maybe social mobility, things like that in the high net worth space.
But in retirement space, this is also a crucial thing. There are going to be things like Irma and other kinds of like social security planning, Roth conversions, things like that that happen. But but tax planning impacts every single strata of wealth.
It's just a matter of the toolkit that you apply to the specific problem that the investor or the household has. It's interesting to me because when you go online and you do research, so much of the literature and so much of the hype is around getting the best trade or generating active management returns.
