Ahoy! This is avast exaggeration. The two biggest players in the tax-aware hedge fund and SMA space manage around $80 billion in this strategy alone.

Jumbo portfolio manager adds tax-aware long/short private fund

Late on Tues (Dec 22, 2025) a few wealth manager pals emailed me a Bloomberg article.

Apparently, JPM is coming to market with a tax-aware long/short private fund, verbosely titled “J.P. Morgan Tax-Smart Disciplined Equity Long Short Strategy.”

This isn’t totally surprising. JPM has been at the long/short game for decades.

The JPMorgan U.S. Large Cap Core Plus Fund (JPLSX),1 a mutual fund, “[u]tilizes a long/short (130/30) strategy that combines an actively managed 100% long portfolio with an active equity long/short overlay portfolio,” launched in late 2005 and still has one of the original portfolio managers (yes… 20 years).

They’ve probably been testing the tax-aware long/short hedge fund behind the scenes for a while.

So, none of this is new, but in some ways it represents the mainstreaming of a complex strategy.

In this article…

  • Tax-aware hedge funds have been around for decades (a brief history)

  • Not all funds are created equal

  • JPM’s fund is the right play for JPM

  • What about separate accounts?

  • What about tax-aware separate account and hedge funds together?

  • What happened to Jones?

Long/short hedge funds have been around for decades

The first instance appears to be A. W. Jones & Co.’s hedge fund, which the mysterious Jones himself managed for 30-some odd years.
