Understanding how each major asset class has performed over the long term — and the risk-return trade-offs involved — is foundational to the portfolio construction and allocation decisions that every family office must make. The following analysis draws from institutional-quality data sources including Cambridge Associates, MSCI, the Cliffwater Direct Lending Index, NCREIF, Bloomberg, and Goldman Sachs to paint a clear picture of where returns have actually come from over the last 25 years.
1. Public Equities
Since 2000, public equities as measured by the Russell 3000 have generated approximately 8% net annualized returns, according to MSCI Private Capital Solutions. The S&P 500 has performed slightly better, with Cambridge Associates data showing annualized returns of approximately 9.4% over the same period. Global equities (MSCI World Index) have averaged just over 8% annually over the long term.
The key characteristics of public equities are high liquidity, daily pricing transparency, and significant volatility — with standard deviations typically in the 15–20% range. Concentration risk has become notable in recent years, with the “Magnificent 7” stocks alone accounting for over half of the S&P 500’s gains in 2024.
2. Private Equity
Since 2000, private equity (buyout) has generated a net annualized time-weighted return of approximately 13%, according to MSCI Private Capital Solutions. The Cambridge Associates US Private Equity Index shows a pooled net return of 12.09% over the last 25 years. The Global PE Index has outperformed the MSCI World Index by more than 500 basis points annualized on a net basis, according to KKR’s analysis.
Past performance is not indicative of future results. Private equity returns are reported net of fees but reflect pooled index data; individual fund performance varies significantly based on manager selection, vintage year, and strategy.
This premium compensates investors for illiquidity (typical 7–10 year lock-ups), J-curve dynamics in early years, and the manager selection risk that is significantly higher in private markets. Average net excess returns over public equities have been approximately 400 basis points across long horizons.
The outperformance is driven by active ownership, operational improvement, strategic focus, better governance, and a long-term approach to value creation that quarterly earnings pressure does not permit in public companies. Analysis from MSCI and Cambridge Associates confirms that private equity has historically outperformed public markets across the major time horizons studied — and that public equities experienced larger reported declines during periods of stress relative to private equity (though private equity valuations are updated less frequently).
Reported private equity volatility may understate economic risk due to infrequent portfolio valuations. Manager selection is a significant driver of outcomes; median and lower-quartile managers may not outperform public markets.
3. Public Fixed Income
Public fixed income, as measured by the Bloomberg U.S. Aggregate Bond Index, has delivered annualized returns of approximately 3.5–4.5% over the last 25 years, with significantly lower volatility than equities (standard deviation typically 3–5%). Over the past fifteen years specifically, investment grade bonds delivered annualized returns of approximately 1.8%, reflecting the impact of the historically low interest rate environment following the global financial crisis.
But the headline volatility figures mask the real risk. In March 2020, investment-grade corporate bond funds experienced drawdowns of nearly 19% in just three weeks — losses comparable to the equity market — before Federal Reserve intervention stabilized markets. In 2022, the Bloomberg Aggregate posted a loss of more than 13%, its worst calendar year on record by a wide margin, while 10-year Treasuries fell more than 15%. These episodes exposed a critical vulnerability: publicly traded bond funds carry meaningful market risk and liquidity risk that their long-term volatility statistics do not fully reflect. Rising inflation and high sovereign debt levels have added structural headwinds.
It is worth distinguishing between yield (the income a bond pays) and total return (yield plus or minus price changes). For much of the past fifteen years, yields on investment-grade bonds hovered near historic lows — often below 2.5% — leaving investors with minimal income and high sensitivity to rising rates. With yields now in the 4.5–5% range, the income component provides a meaningfully stronger cushion against price volatility than it did for most of the prior decade. For family offices, this shift makes fixed income more competitive as a portfolio stabilizer, though still well below the return profile of private credit.
The lesson of 2020 and 2022 is that fixed income, while potentially useful for portfolio balance, is not a substitute for genuine capital preservation.
4. Private Credit
Private credit is a newer asset class in institutional terms, with the Cliffwater Direct Lending Index (CDLI) — the industry’s benchmark — reconstructed back to 2004 using SEC filings from business development companies. Over the past fifteen years, private credit has delivered annualized returns of 10.1%, compared to 8.6% for high yield bonds and 1.8% for investment grade bonds.
A Remarkable Track Record
Hamilton Lane’s analysis shows that private credit has outperformed public markets for 23 consecutive vintage years — a track record that few other private asset classes have matched. The CDLI delivered 10.06% over the trailing 12 months as of Q2 2025, with credit losses at 0.75% annually — below the long-term average of 1.01%, though future credit conditions may differ.
Private credit returns reflect index-level data from the Cliffwater Direct Lending Index. Individual fund and BDC performance may differ materially. Floating-rate structures reduce interest rate risk but do not eliminate credit or default risk.
The asset class benefits from floating-rate structures that provide natural protection in rising rate environments, an illiquidity premium, and direct origination that allows for stronger covenants and underwriting than broadly syndicated markets. Its growth was catalyzed by the Dodd-Frank Act of 2010, which constrained bank lending to middle-market companies.
The asset class is currently facing its first meaningful liquidity test at scale, with several large semi-liquid BDC vehicles capping or prorating investor redemptions in late 2025 and early 2026 amid a wave of retail withdrawal requests. As private credit has become increasingly democratized — extending beyond institutional and family office investors into the broader retail market — some newer participants have reacted to negative headlines in ways more typical of public market sentiment, creating redemption pressure that the underlying fundamentals do not appear to warrant. The quarterly redemption caps (typically 5% of NAV) that most funds maintain are a standard structural safeguard designed to preserve portfolio stability and protect all investors from forced asset sales — not a restriction on access — though media coverage has at times characterized them otherwise, compounding anxiety among the same investors the gates are designed to protect.
Importantly, income distributions have continued across the sector, and a Preqin analysis of the underlying loan portfolios found credit quality broadly in line with the wider market — suggesting that the redemption pressure reflects a misunderstanding of how these fund structures operate rather than deteriorating loan fundamentals for well-structured institutional allocations.
5. Real Estate — Multifamily
Multifamily (apartments) real estate has been one of the strongest-performing property sectors over the last 25 years, driven by demographic tailwinds, urbanization, housing affordability constraints, and steady rental demand. As measured by the NCREIF Property Index apartment sector, multifamily has delivered long-term annualized total returns of approximately 8–10%, with income yields typically in the 4–5% range providing a durable cash flow base.
Multifamily has historically exhibited lower volatility than other commercial property types, experienced shorter vacancy periods, and benefited from shorter lease terms that allow rents to reset to market more quickly — providing a natural inflation hedge. The sector consistently records the lowest cap rates (the ratio of net operating income to property value — a lower cap rate implies higher relative pricing and lower perceived risk) of all commercial property types, reflecting deep institutional confidence in its risk-return profile.
6. Real Estate — Global Holdings
Over the last 25 years, listed U.S. real estate generated returns of approximately 9% and global real estate approximately 7%, according to CBRE Investment Management. Private real estate as measured by the NCREIF Property Index (NPI) has delivered long-term annualized returns of approximately 8–9% since inception, with income returns historically contributing more than half of total returns.
Understanding Cap Rates
A capitalization rate (cap rate) is one of the simplest ways to evaluate a real estate investment. It answers a straightforward question: if I paid cash for this property, what annual income would it generate as a percentage of the purchase price?
Cap Rate = Net Operating Income ÷ Property Value
For example, a property generating $500,000 in annual net operating income and valued at $10 million has a 5% cap rate. From a pure income standpoint, a higher cap rate means the property’s cash flows pay back the investment more quickly. But cap rates are also a risk signal: properties with stable, predictable cash flows and strong institutional demand tend to trade at lower cap rates (buyers accept less current yield because they value durability and potential appreciation), while properties with weaker fundamentals trade at higher cap rates to compensate for risk. The best investments balance both — attractive current yield and durable cash flows that can continue paying down the acquisition over time.
The recent period (2022–2024) was challenging globally, with higher mortgage rates and cap rate expansion dampening returns — though 2025 showed signs of recovery, with core real estate funds posting the highest one-year return since Q4 2022.

†Reported private equity volatility varies significantly based on manager selection, portfolio diversification, and vintage year concentration. Upper-quartile buyout managers have historically delivered net returns in the range of 14–18% (per Preqin and Cambridge Associates data) with reported volatility in the range of 3–6% — sitting at the higher end of the return spectrum and the lower end of the volatility spectrum simultaneously. The full private equity universe, including median and lower-quartile managers, exhibits substantially wider volatility and lower returns — underscoring that manager selection is the primary driver of both return and risk outcomes. Additionally, reported private equity volatility is based on quarterly appraisal valuations rather than daily market pricing, which produces lower observed volatility than public equities; the underlying economic volatility of private equity businesses is higher.

The Key Takeaway for Family Offices
Private equity has produced among the highest risk-adjusted returns over the last quarter century, but it requires illiquidity tolerance, disciplined manager selection, and long time horizons — qualities that are naturally aligned with the multigenerational investment mandate of a family office. The families that allocated meaningfully to this asset class 25 years ago have compounded wealth at rates that public-only portfolios generally did not match. The opportunity cost of not participating in private markets has been meaningful.
All return figures cited are historical and based on index-level data from the sources listed. They do not represent the performance of any specific fund, product, or strategy offered by Integrity IDF. Diversification does not ensure a profit or protect against loss.
Real estate — particularly multifamily — has provided durable income, inflation protection, and powerful tax advantages (depreciation, cost segregation, 1031 exchanges, and the step-up in basis) that make it uniquely suited to multigenerational wealth transfer. Public fixed income, while essential for liquidity and stability, has struggled to deliver meaningful real returns over the last 15 years, though higher yields today have improved the forward outlook.
