Private equity vs the stock market: what actually changes for a saver

In short:
The stock market prices every day, unlisted holdings are valued periodically, often once or twice a year, based on appraisals.
A share sells in a day, a stake in an unlisted fund is locked for 8 to 10 years.
The annual fees of a private equity fund far exceed those of an index ETF and must be built into any return calculation.
The two worlds are not opposites: unlisted assets work as a minority pocket inside an already diversified portfolio.

Two opposite ways of owning a company

Buying a share means owning a fraction of a listed company, whose price is set continuously by a market. Subscribing to a private equity fund means handing money to a manager who will pick the companies, negotiate entry and exit prices, and return the proceeds of disposals to you over the years.

That difference in mechanics produces four concrete gaps.

1. Valuation

A share price moves every second. The value of an unlisted holding is estimated periodically by the manager, using regulated valuation methods. A consequence that is often misread: the low reported volatility of an unlisted fund does not mean lower risk, only that the price is observed less often.

2. Liquidity

This is the most structural gap.

	Stock market	Private equity
Time to exit	One day	8 to 10 years
Exit price	Known to the second	Known at disposal
Early exit	Always possible	Rare, and discounted when available

3. Fees

A broad index ETF commonly charges under 0.30% a year. A private equity fund stacks substantially higher annual management fees, plus a performance fee charged on gains above a threshold. That gap must be deducted before comparing gross performance.

4. Diversification

A global ETF gives exposure to hundreds or thousands of companies in one line. A private equity fund often holds fifteen to thirty positions. Concentration is therefore much higher, and the manager’s skill weighs far more heavily on the outcome.

How the two combine

In a standard allocation, unlisted assets are treated as a satellite pocket, capped in proportion, sitting alongside a liquid, diversified core. The logic is simple: money placed in private equity must not be money you could need within ten years.

Frequently asked questions

What is the difference between private equity and the stock market?

The stock market gives a continuous price and immediate exit, on listed companies. Private equity covers unlisted companies, with periodic valuation and capital locked for 8 to 10 years. Fees are significantly higher in private markets, and the number of companies held is far smaller, which makes the manager’s selection decisive.

Is private equity riskier than the stock market?

The risk is of a different nature. On the stock market it shows immediately in price volatility. In private markets it materialises later, at disposal, and it adds illiquidity risk: the inability to exit when you want. Lower reported volatility therefore does not mean lower risk.

There is no universal rule, but common practice treats it as a minority pocket within an already diversified portfolio, funded only with money you will not need before the fund’s life ends, which is roughly ten years.
