tax mgt 🤝 risk mgt

This is my shorthand for “tax management is risk management.”

I’ve been saying this a lot lately.

In direct indexing, “risk” usually means underperformance relative to some benchmark (“poor tracking error,” as they say).

In tax-aware long/short strategies (130/30, 250/150, etc.), “risk” means the same thing, though there are many additional sources of said risk.

Tax-aware long/short assets are well above $150 billion now. You can get up to speed on tax-aware long/short here.

I’ve been exploring local risks, like short squeeze, lender policy changes, and manager underperformance (AQR’s recent research on this is excellent), for several months now.

Today, I’m zooming out and looking at a systemic risk and asking What if everyone unwinds their leverage at the same time?
