Public Market Equivalent
A public market equivalent, or PME, restates a private real estate fund’s result in public-market terms. In the mPME method, the fund’s actual dated contributions buy shares of a chosen public index and its distributions sell them, so the investor’s cash moves on the fund’s own schedule. Comparing the fund’s outcome with the outcome of that hypothetical index position shows whether the private fund beat the public alternative. The comparison is relative to the index picked and does not make the two investments identical.
What a PME asks of a private fund
A PME holds the fund’s cash flows fixed and swaps the return path. The dates and sizes of every capital call and distribution come from the fund. A public index supplies the price movement those same dollars would have experienced.
The output answers one relative question: did the investor’s money, moving on the fund’s schedule, do better inside the fund or inside the index?
Because the schedule is fixed, two funds with the same total cash multiple can face different index paths. Early cash back and late cash back meet different public prices.
How mPME turns capital calls into index purchases
The mPME method applies public-index share purchases and sales to a private fund’s cash flow schedule. Each contribution buys index shares at the index price on the contribution date, and each distribution sells index shares at the index price on the distribution date.
Shares still held on the measurement date are valued at the index price that day, and that ending value is set against what the fund returned or still reports.
Where IRR and a PME diverge
IRR is the discount rate that sets the net present value of a fund’s dated contributions and distributions to zero. Because it weights dates, a dollar returned early lifts it more than a dollar returned late.
On its own, an IRR says nothing about what a public market paid over the same stretch. The PME supplies that reference by running the identical cash flow schedule through an index.
The two measures answer different questions. IRR summarizes the fund’s own timing-weighted result, while the PME describes the gap between the fund and a public alternative on the same timing.
Choosing the index and reading appraisal lag
The index carries the whole comparison. REITs offer greater liquidity and lower fees than private real estate vehicles and have shown similar long-term performance to private real estate, which is why a REIT index is a common public reference for a real estate fund.
Pricing frequency separates the two sides. REIT shares are priced daily, and private valuations follow the appraisal process. Private real estate valuations have lagged REIT valuations by about three to four quarters because of that timing difference.
A separate measurement of trends puts the gap at roughly a year: over the past 20 years, public market trends have led those of private real estate by roughly a year. The two figures describe different things, valuations in one case and trends in the other, so they do not conflict.
Over a short window, an index can already show a move that appraisal-based fund values have not yet recorded. A PME that ends in the middle of such a move mixes performance with reporting delay.
What a PME gap leaves out: liquidity and fee layers
An index position can be sold on any trading day. Some non-traded real estate vehicles state that no public market is expected for their shares, which can make a sale difficult.
Sellers of private equity interests may have to discount substantially to exit because relatively few secondary-market buyers exist. A PME gap carries no adjustment for that cost.
Fund investors commit capital for years and pay both a management fee and a performance fee. The fund-side result already reflects whatever those fees and the structure did to the investor’s cash flows, so a gap measured net of fees is a gap after those costs.
“The investors (LPs) commit capital for about five to eight years and agree to pay a management fee annually (1.5-2% of assets under management) and a performance fee (20% of the profits generated by the fund).”
Worked example: a $10,000,000 fund commitment against an index
This hypothetical comparison uses the same $10,000,000 of capital and the same two-year period in both cases. The fund calls $10,000,000 at the start, distributes $1,000,000 at the end of year one and distributes $13,000,000 at the end of year two. The flows are net to the investor, and the index position carries no fees.
Fund result: $1,000,000 plus $13,000,000 equals $14,000,000 returned. Divided by $10,000,000 contributed, the fund’s multiple is 1.40x.
Base case, index rises 10 percent in year one and 5 percent in year two. The $10,000,000 buys index shares that are worth $11,000,000 after year one ($10,000,000 multiplied by 1.10). Selling $1,000,000 to match the fund’s first distribution leaves $10,000,000 invested. Year two growth takes that to $10,500,000 ($10,000,000 multiplied by 1.05). Adding the $1,000,000 already taken out gives $11,500,000, a multiple of 1.15x. The fund finishes ahead by $2,500,000 ($14,000,000 minus $11,500,000).
Stressed case, index rises 30 percent in year one and 10 percent in year two. The position is worth $13,000,000 after year one ($10,000,000 multiplied by 1.30). The $1,000,000 sale leaves $12,000,000. Year two growth takes it to $13,200,000 ($12,000,000 multiplied by 1.10). Adding the $1,000,000 gives $14,200,000, a multiple of 1.42x. The fund now trails by $200,000 ($14,200,000 minus $14,000,000).
The fund’s cash flows are identical in both cases, and so are the capital and the time span. Only the index path changed, and the verdict flipped. A full mPME uses dated flows and index prices on each date, and an IRR on each side needs a root-finding step. The multiples here show the buy and sell mechanics.
Mistakes that distort a PME reading
Setting a fund IRR beside an index’s reported annual return mismatches timing. The IRR is built from dated contributions and distributions, and the index return assumes a single investment over the full period. The mPME method removes the mismatch by running the fund’s own flows through the index.
Reading the gap as a verdict on the sponsor attributes too much. In the example, the fund’s 1.40x leads a 1.15x index case and trails a 1.42x index case with no change in the fund. The index path alone decided the sign of the result.
Using a stale ending value for the private side misstates the endpoint. Private valuations can lag REIT valuations by about three to four quarters, so a remaining fund balance marked behind public prices can understate or overstate the gap, depending on which way public prices moved.
Treating a cash multiple as an IRR overlooks timing. Two funds returning the same $14,000,000 on $10,000,000 can have different IRRs if the cash arrives on different dates, and a multiple cannot show that.
Assuming the chosen index mirrors the fund’s holdings goes beyond what the method says. The comparison shows how a public index would have done on the fund’s schedule, and the index owns different assets, uses different pricing and carries different liquidity.
Questions for reviewing a PME calculation
Which public index supplies the return path? The index defines the comparison, and a different index can reverse the answer.
Are all contributions and distributions dated and included? The share purchases and sales only track the fund if every dated flow is applied.
What is the measurement date? Remaining hypothetical shares need an index price on that date to be valued.
Are the fund flows net of fees? A gross fund series set against an index with no fee drag is a different comparison from a net one.
How is the fund’s remaining value marked? Appraisal-based values can trail public prices by about three to four quarters.
Does the comparison cover the same period for both sides? A shifted start or end date changes the index path.
Is the result a multiple or an IRR? A multiple ignores timing, while an IRR reflects it.
