Do you think your ISA should include private equity?

A portion of the almost £900 billion in UK ISAs is sought after by the private equity sector

However, there is a compelling argument to keep it out and see why.

The VIP area of investing has always been private equity. Large organizations entered. You weren't. The velvet rope is descending now. The FCA has approved long-term asset funds' eligibility for stock and share ISAs as of April 6. But should your ISA include private equity?

Hargreaves Lansdown and Schroders have already collaborated to list the first on a significant retail platform. The government is supporting the initiative because it is eager to direct household savings into the real economy. We are informed that returns previously only available to the wealthy can now be shared by regular investors.

It sounds excellent. However, two recent papers by Nori Gerardo Lietz at Harvard Business School and Ludovic Phalippou at Oxford Sad dissect it. They contend that the upside isn't being democratized. It has to do with the expense, complexity, and danger.

Should you add private equity to your ISA for stocks and shares?

Will my ISA's private equity yield significant returns?

One argument is used to support private equity: better returns for your ISA. The figures supporting that assertion are not reliable.

Consider the internal rate of return (IRR), which is the industry's preferred metric. Phalippou demonstrates that it does not gauge what the majority of people believe.

Over the course of 18 consecutive annual filings, investment firm KKR reported a gross internal rate of return (IRR) of approximately 25.5 percent since its founding. It sounds fantastic. However, IRR does not measure how quickly your wealth compounds; rather, it measures when money enters and exits a fund. What Phalippou refers to as "implausibly large" terminal wealth would result from treating that 25.5 percent as a compound annual return. An impressive number, not an informative one.

When private equity is compared like-for-like to public markets, the picture changes. Lietz uses Pitchbook's public market equivalent methodology to compare the actual cash flows of private equity funds to comparable investments in the S&P 500.

Private equity's advantage has disappeared over the last 15 years, and it is now negative at -4.62 percent for the last five years. The premium that provided justification for the entire exercise has vanished.

Selecting better managers won't solve this. For vintages after 2000, buyout funds' performance persistence has vanished. There is no discernible difference in the final results when managers are divided into fundraising quartiles. It is a pipe dream that a retail platform will reliably identify the winners.

When you invest in private equity, where does the money actually end up?

Fees would consume the majority of the returns before they reached you, even if private equity fulfilled its marketing promises.

According to Phalippou's calculations, standard institutional private equity fees already account for roughly 7% of returns each year. These fees include performance fees, management fees, and portfolio-company costs that are rarely included in headline figures. For distribution, platform, and supervision, retail wrappers add about three more percentage points. One of the first products to hit ISA shelves is the Schroders Capital Global Private Equity LTAF, which has wrapper fees of more than 2% annually. That's prior to the underlying fund expenses.

Since platforms and target-date managers add a similar fee layer, Lietz's fund-of-funds data provides the closest indication of what retail buyers will actually encounter. As a result, she consistently underperformed, with a return multiple of less than 1.0 in almost all of the periods she studied.

And there are the appraisals. A dubious net asset value (NAV) was considered an accounting curiosity in traditional private equity. Every move has immediate financial repercussions because investors in open-ended retail funds buy and sell at reported net asset values.

The retail fund of Hamilton Lane purchased private equity stakes in 2024 at about 80% of stated NAV, marking them up to 100% the following day. That isn't an error in rounding. It is a transfer of wealth from new investors to current holders that is recorded as a gain.

The same is true of LTAFs. Monthly evaluations are conducted. Notice periods for redemption are at least ninety days long. If you buy in at an optimistic price, you won't be able to exit quickly; worse, you might be helping someone else do so.

The echo in Woodford.

We've been here before. The failure of the Woodford Equity Income fund was not caused by a single manager's poor decisions. Because the structure was unsoundilliquid assets inside a vehicle promising daily dealingit collapsed. See our article on how Woodford investors are suing Hargreaves Lansdown for the full cost borne by regular savers.

LTAFs are better made. In order to stop a run, there is a notice period. The deeper tension hasn't subsided, though. Although these funds are categorized as "restricted mass market investments" by the Financial Conduct Authority, platforms are able to actively encourage savers to invest in them thanks to the new targeted support regime. Additionally, under-65s will be limited to 12,000 in a cash ISA starting in April 2027, encouraging those who wish to use their entire 20,000 allowance for investment products. The risks are growing at the same time that the options are getting smaller. Litigation is "not merely possible but predictable," according to Phalippou's ruling.

A more straightforward path to private equity exposure.

There is a less expensive and more liquid alternative if you want to be exposed to the economics of private equity.

Lietz discovered that their flagship private funds were easily outperformed by a basket of publicly traded private equity firms.

US-listed private equity stocks outperformed their companies' private vehicles by an average of 23% over the five years prior to December 2024. You gain complete exposure to the management fees, carried interest, and asset growth that propel private equity profits, as well as transparent pricing and daily liquidity.

To put it simply, the best way to make money from private equity is to purchase the businesses that sell the pricey goods instead of the expensive ones.

This spring, if a platform offers you an LTAF in your ISA, make sure to ask three questions before committing. What are the redemption terms in a stressful situation, who values the fund, and what is the total annual cost across all layers? If you are unable to obtain clear answers, that provides all the information you require.
