The All-Terrain Modern Model Portfolio: Engineered for the Next Decade

Global Multi-asset Diversified Portfolio (Adventurous)

This portfolio is segmented into two core categories: Liquid/Traditional Core and Alternative/Satellite Allocations. The core provides stability and market-based returns, while the satellite seeks higher growth and diversification benefits.

Core – 70% (Liquid & Traditional)

This is the foundation of the portfolio, invested in highly liquid, publicly traded securities.

1. Global Equities (Developed Markets)
   • 30% – To capture growth from the world’s largest and most stable economies. Ideally via Low-cost ETFs or Index Funds
   • 15% – US Total Stock Market ETF (e.g., tracks VTI or a S&P 500 index)
   • 10% – Developed International Markets ex-US ETF (e.g., tracks VXUS or EFA)
   • 5% – Global Small-Cap Value ETF (for factor diversification and higher potential return)
2. Emerging Markets Equities
   • 10% : Provides access to higher growth potential in emerging economies, though with higher volatility and political risk. Best supplemented with a single, broad-based ETF like IEMG or VWO
3. Global Bonds (Fixed Income)
   • 25% : Provides stability, income, and a hedge against economic downturns. It is the primary risk-mitigating component
   • 15% – Global Aggregate Bond ETF (Hedged) (e.g., BNDW). The currency hedging reduces volatility for a home-currency investor.
   • 10% – Inflation-Protected Securities (TIPS) ETF (e.g., TIP). Protects against unexpected inflation
4. Listed Real Estate (REITs)
   • 5% : Provides exposure to the real estate market with high liquidity. Offers diversification and a hedge against inflation due to rental income and property value appreciation. A global REIT ETF like VNQ (US-focused) or REET (Global)

Satellite – 30% (Alternatives)

This portion of the portfolio is dedicated to less traditional, often less liquid, and higher-risk/higher-return assets.

5. Private Equity
   • 10% : To capture the “illiquidity premium” – the potential for higher returns by investing in companies not listed on public exchanges. This is a key driver of alpha (excess return) in sophisticated portfolios. Ideal play is to access through a fund-of-funds or a venture capital/private equity fund. Caveat: Minimum investable amounts are often very high. Accessible Alternative: Use a Publicly Traded Private Equity ETF like PSP (Invesco Global Listed Private Equity ETF), which holds shares of companies like Blackstone and KKR that invest in private equity. Note: This is not pure private equity but a good proxy.
6. Digital Assets & Cryptocurrencies
   • 10% : A speculative allocation for asymmetric return potential and exposure to a new, non-correlated asset class (decentralized digital networks)
   • 7% – Bitcoin (BTC): The flagship cryptocurrency, viewed as “digital gold” and a store of value
   • 3% – Ethereum (ETH) & Broad Market Crypto Index: Ethereum for its smart contract platform utility and a small allocation to a basket of other major assets (e.g., via an ETF like BITB for Bitcoin or a tokenized index fund). This is a highly volatile allocation and should be sized carefully.
7. Commodities & Natural Resources
   • 5% : Acts as a hedge against inflation and geopolitical shocks. Tends to perform well when traditional stocks and bonds are struggling. A broad-based commodities ETF like GSG (iShares S&P GSCI Commodity Indexed Trust) or DBC (Invesco DB Commodity Index Tracking Fund)
8. Absolute Return / Market Neutral Strategies
   • 5% : To provide returns that are uncorrelated to the direction of the stock or bond markets. These strategies aim to generate positive returns in all market conditions (e.g., long/short equity, managed futures). A multi-alternative ETF or mutual fund like AQMNX (AQR Managed Futures Strategy) or DBMF (iM DBi Managed Futures Strategy ETF)

The Base Case: Expected Annual Return: 7.5% – 9.5% (Nominal, Pre-Inflation)

This range is a reasonable long-term (10+ years) expectation for a portfolio with this risk profile.The calculation is based on building a weighted average return estimate for each asset class, using a combination of historical long-term data and forward-looking expectations. You should invest in this portfolio with the expectation that, over a 15-20 year period, it has the potential to deliver an average annual return of ~7.5-9.5% before inflation. However, you must be psychologically and financially prepared for a very bumpy ride and the possibility that the actual result could fall outside this range, heavily influenced by the performance of its alternative allocations.

Crucial Context and Realistic Expectations

(a) The Impact of Inflation

The 7.5% – 9.5% target is a nominal return. The real return (what actually grows your purchasing power) is this figure minus inflation.

• If inflation averages 2.5%, the real return expectation would be 5.0% – 7.0%
• If inflation averages 3.0%, the real return expectation would be 4.5% – 6.5%

(b) The Range of Outcomes is Extremely Wide

This portfolio is not designed for smooth returns. The actual path will be volatile.

• Bull Market Scenario: In a year where equities are up 20% and crypto is up 100%, the portfolio could easily return 15-20% or more
• Bear Market Scenario: In a year like 2022, where both stocks and bonds fall sharply and crypto crashes, the portfolio could be down -15% to -20%

The long-term average of ~7.5-9.5% would be the result of these wild swings averaging out over decades.

(c) Key Variables That Will Drive Actual Returns:

• Success of Private Equity Allocation: Can you access top-tier funds that actually deliver the illiquidity premium?
• Performance of Cryptocurrencies: Will Bitcoin and Ethereum behave more like “digital gold” and “digital oil” with steady growth, or will they remain hyper-speculative?
• Macroeconomic Environment: Persistent high inflation would hurt bonds but help commodities and real estate. A major recession would hit equities and private equity hard.

Now comes the important notes, fine prints and caveats

Rebalancing: This portfolio requires annual or semi-annual rebalancing to maintain the target allocations. Due to the high volatility of assets like crypto, you may need to rebalance that segment more frequently.

Risk Profile: This is an adventurous risk profiled portfolio. The 40% allocation to equities (30% Global + 10% EM) and 20% to high-risk alternatives (Private Equity & Crypto) means it can experience significant drawdowns and heightened volatility during undue market stress.

Accessibility: Allocations to Private Equity and, to a lesser extent, Absolute Return strategies can be difficult and expensive for retail/ individual investors to access directly. The ETF proxies mentioned are a practical workaround.

Currency Risk: the global equity and bond allocations introduce currency risk. Consider hedging the core international bond allocation, as shown in the model.

Tax Efficiency: The placement of assets matters. Hold high-yielding assets like REITs and bonds in tax-advantaged structures / accounts If possible, and growth assets like equities in taxable accounts, considering the local tax laws where assets are domiciled.
