Private equity is still gunning for mom and pop investors

• Retail investors can already buy into special purpose acquisition companies, which act like concentrated buyout funds (albeit with slightly more shareholder protections). They also can invest in publicly-traded private equity firms, which are little more than a collection of opaque underlying funds.

Even if SoftBank doesn't figure this out — or simply opts against it — there are others working toward similar ends.

• Most notable is the rowing cohort of "GP stake" funds, such as Dyal Capital and Goldman Sachs' Petershill.
• The are funds that buy passive, minority positions in other, privately-held private equity firms. They primarily generate returns via firm cash-flows (i.e., a cut of underlying fund fees), but there isn't yet a way to fully exit.
• One possibility is that enough of these firms will launch so that a true secondary market emerges, but there also is talk about trying to bring one of these funds public. Almost a quasi-ETF of private equity funds, like how SoftBank Vision would create a quasi-ETF of tech unicorns.

The bottom line: Private equity remains constrained by its present inability to tap retail investors and defined contribution plans. It has no interest in settling for that status quo.
