ETA vs. Public Markets & Hedge Funds

For most investors, publicly traded stocks and bonds form the core of their portfolio. The S&P 500 is the benchmark against which all other strategies are measured. Hedge funds promise alpha through sophisticated strategies. Entrepreneurship Through Acquisition (ETA) offers something different entirely — direct ownership of a private business with active operational involvement. This comparison examines how ETA stacks up against public equities and hedge funds across returns, risk, liquidity, correlation, and portfolio construction.

Return comparison: the core numbers

The long-term annualized return of the S&P 500, including dividends, is approximately 10% to 11% nominal (roughly 7% to 8% real after inflation). This is the hurdle rate that any alternative investment must clear to justify its complexity and illiquidity.

ETA clears it by a wide margin. The 2024 Stanford Search Fund Study reports a median pre-tax IRR of approximately 33% for acquired search funds, with a mean return on invested capital of 5.2x. Even the bottom quartile of successful search fund acquisitions delivers returns that match or exceed public market averages. For investors who build diversified portfolios of 10 or more search fund investments, the expected portfolio IRR of 25% to 35% represents a 15 to 25 percentage point premium over public markets.

The hedge fund comparison

Hedge funds have historically marketed themselves as the primary source of alpha relative to public markets. The reality has been disappointing. According to data from Hedge Fund Research (HFR), the HFRI Fund Weighted Composite Index has delivered annualized returns of approximately 6% to 8% over the past 15 years — after fees, underperforming the S&P 500 in most periods. The average hedge fund charges 1.5% management fees plus 15% to 20% performance fees (the "2/20" model, though actual fees have compressed slightly). After these fees, the median hedge fund has struggled to generate meaningful alpha.

ETA has no management fees, no performance fees layered on top of investor returns, and a track record of delivering 3x to 5x the absolute return of the average hedge fund. The structural advantage is clear: in ETA, the operator's compensation comes from equity ownership, not from fees charged on assets under management.

Liquidity: the fundamental trade-off

The single most important difference between ETA and public markets is liquidity. Public equities can be sold in seconds at transparent market prices. A search fund investment is locked up for five to seven years with no secondary market and no ability to exit before the operating CEO decides to sell the business.

This illiquidity is not merely an inconvenience — it is a structural feature that creates both risk and opportunity. The risk is straightforward: if you need capital during the hold period, it is simply unavailable. The opportunity is that the illiquidity premium — the excess return investors demand for accepting illiquidity — is well-documented in academic finance. Studies estimate the illiquidity premium in private markets at 3% to 5% annually. ETA's 20%+ premium over public markets substantially exceeds the typical illiquidity premium, suggesting that the returns are driven by genuine operational value creation, not just compensation for illiquidity.

The emotional toll of illiquidity

The psychological dimension of illiquidity deserves honest discussion. Public market investors can check their portfolio value daily and sell instantly if they lose confidence. Search fund investors receive quarterly financial reports and annual valuations but have no exit mechanism. When the underlying business hits a rough patch — a key customer loss, a failed product launch, an industry downturn — investors must sit with uncertainty and trust the CEO to navigate through it. This emotional experience is fundamentally different from public market investing and is not suitable for every investor temperament.

Conversely, illiquidity protects investors from their own behavioral biases. Public market investors systematically buy high and sell low, driven by fear and greed. The average equity fund investor underperforms the funds they invest in by 1% to 2% annually, according to Dalbar's Quantitative Analysis of Investor Behavior. Search fund investors cannot panic-sell during a downturn, which forces the patience that long-term wealth creation requires.

Correlation and diversification benefits

One of the most compelling arguments for including ETA in a portfolio is its low correlation with public markets. Search fund returns are driven primarily by company-specific operational factors — the CEO's ability to grow revenue, improve margins, and build organizational capability — rather than by macroeconomic variables or market sentiment that drive public equity prices.

Empirical analysis of search fund returns shows limited correlation with the S&P 500 (estimated at 0.2 to 0.3), which is significantly lower than the correlation of hedge funds with public markets (typically 0.5 to 0.7 for equity-oriented strategies). This low correlation means that adding ETA to a traditional stock-and-bond portfolio can improve the portfolio's risk-adjusted returns — higher expected returns without a proportional increase in volatility.

Sharpe ratio comparison

The Sharpe ratio measures return per unit of risk (volatility). The S&P 500 has historically delivered a Sharpe ratio of approximately 0.4 to 0.5. Hedge funds average roughly 0.3 to 0.5, depending on the strategy. Estimating Sharpe ratios for private investments is methodologically challenging because valuations are infrequent and potentially smoothed, but reasonable estimates for a diversified ETA portfolio suggest Sharpe ratios in the range of 0.8 to 1.2 — roughly double that of public equities. Even after adjusting for the potential smoothing bias in private market valuations, ETA offers superior risk-adjusted returns.

Information advantages in the SME market

Public equity markets are among the most informationally efficient markets in the world. Thousands of analysts, quant funds, and algorithmic traders process every piece of public information within milliseconds. Generating alpha through superior information is extraordinarily difficult — even most professional fund managers fail to beat their benchmarks consistently.

The SME market where search funds operate is profoundly inefficient. There are no analyst reports, no public financial filings, no quarterly earnings calls. Information about individual businesses is scarce and fragmented. A diligent searcher who conducts thorough industry research, builds relationships with brokers, and performs deep due diligence has a genuine information advantage. This information asymmetry is a durable source of alpha that is not available in public markets and is unlikely to be competed away anytime soon.

• No public comparables: SME valuations are based on rough EBITDA multiples and comparable transactions, not on continuous price discovery. Skilled buyers can identify businesses trading at discounts to intrinsic value.
• Relationship-driven transactions: Many SME acquisitions occur through personal relationships rather than competitive auctions. Sellers often prioritize finding a trustworthy buyer who will protect their employees and legacy over maximizing the sale price.
• Operational improvements: Even after acquisition, the new CEO has proprietary information about the business and can identify value-creation opportunities invisible to outside observers.

Why family offices allocate to search funds

Family offices have been among the earliest and most enthusiastic institutional adopters of search fund investing. Their reasons illuminate the asset class's structural advantages:

• Long time horizons: Unlike pension funds or endowments that must make annual distributions, many family offices have perpetual time horizons. They can comfortably lock up capital for five to seven years without liquidity concerns.
• Concentrated conviction: Family offices are often built on the wealth created by a single business. The principals understand — viscerally — the value of backing a talented operator to run a single company. They are comfortable with concentration because it mirrors their own wealth-creation experience.
• Mentorship opportunity: Many family office principals enjoy mentoring young CEOs. Search fund investing provides a structured way to share expertise while earning strong returns.
• Modest check sizes: Search fund investments ($50,000 to $200,000 per search fund) represent small allocations for most family offices, making it easy to build diversified portfolios without significant concentration risk.

Portfolio allocation framework

How much should a well-diversified investor allocate to ETA? The answer depends on liquidity needs, time horizon, and risk tolerance, but a reasonable framework is:

• Conservative allocation (5% to 10%): For investors who need significant liquidity and have limited experience with private markets. Even a 5% allocation to ETA, earning 30% IRR, adds approximately 1% to 2% to overall portfolio returns — meaningful over decades.
• Moderate allocation (10% to 20%): For accredited investors with stable income streams who can tolerate five-to-seven-year lock-ups. This allocation provides meaningful return enhancement while maintaining a predominantly liquid portfolio.
• Aggressive allocation (20% to 35%): For family offices and ultra-high-net-worth individuals with long time horizons and no near-term liquidity needs. At this level, ETA becomes a material return driver and a genuine diversification tool.

Vintage year diversification

Just as with PE and VC, ETA investors should diversify across vintage years. Rather than committing an entire allocation at once, investors should deploy capital across three to five years, backing two to four new searchers per year. This approach smooths the impact of economic cycles on acquisition valuations and provides a steady stream of entry and exit points. Over time, a mature ETA portfolio generates a continuous flow of distributions as older investments exit while newer investments are still in the growth phase.

When public markets are the better choice

Despite ETA's compelling return profile, public markets remain essential for most investors:

• Liquidity needs: If you may need access to your capital within five years, public markets are the only appropriate choice.
• Simplicity: Public market investing through index funds requires no due diligence, no board participation, and no ongoing monitoring. For investors who want truly passive exposure, public markets are unmatched.
• Tax efficiency: Index funds offer exceptional tax efficiency through low turnover and long-term capital gains treatment. ETA returns are subject to more complex tax treatment depending on deal structure.
• Scale: Public markets can absorb any amount of capital instantly. An investor with $100 million to deploy can buy an S&P 500 index fund in minutes. Building a $100 million ETA portfolio would take years and significant sourcing effort.

The optimal approach for most sophisticated investors is not choosing one over the other but combining both. Public markets provide the liquid foundation, while ETA provides the alpha engine. Together, they create a portfolio that is both resilient and high-performing — offering daily liquidity for near-term needs and outsized returns from patient, long-term private market investments.
