Tax-aware long/short AUM update “rampant growth”

At Nuveen/Brooklyn’s nPowered conference in Manhattan earlier this week, all advisers wanted to talk about with me was tax-aware long/short.

The two-sentence explainer of tax-aware long/short is core public equity exposure with roughly market-neutral margin and short portfolio complements. The strategy generally aims for pretax alpha and substantial realized losses.

I’ve written maybe 20 articles on tax-aware long/short exploring various nuances.

Tax-aware long/short is generally available in the following flavors:

  • Separate account vs. limited partnership/hedge fund

  • Low leverage (e.g. 110/10) to high leverage (e.g. 300/200 and more)

  • High/calibrated tracking error vs. low/incidental tracking error

  • Beta vs. market neutral

The “right” solution depends on family circumstances, risk tolerance, and the problem to be solved. Notable cases:

  • Tax-neutral divesting of concentrated public equity positions

  • Post-exit alpha and tax smoothing

  • Alpha and cumulative losses for transitioning between strategies

  • Many, many more use cases

Tax-aware long/short is an incredible planning tool.

It might not solve all problems - investors/advisers should carefully weigh their circumstances to make sure there’s a fit - but the AUM growth (below) reveals that advisers are smitten.
