A study of what a hypothetical $1,000,000 would have become in U.S. stocks versus U.S. Treasuries, and what it took to earn it.
“Family offices and long-horizon investors need return engines that can compound capital without relying solely on public equity beta. SW Flagship's 22-year live record suggests that it has historically delivered a rare combination: materially higher returns than the S&P 500, comparable volatility, lower observed year-end drawdowns than U.S. equities over the same period, daily liquidity, and low correlation to high-grade bonds. The result is not a claim that SW Flagship eliminates risk, nor that past performance will persist. Rather, the evidence supports a clear conclusion: SW Flagship deserves serious due diligence as a liquid diversifying growth allocation within sophisticated portfolios.”
Higher returns came with bigger swings. A balanced look at what an investor had to live through.
SW Flagship combines four features rarely found together: a 22-year continuous live track record, equity-like daily liquidity, materially higher historical risk-adjusted returns than U.S. equities, and low historical correlation to high-grade bonds. Past performance does not guarantee future results.
Where each major asset class landed. Up (more return) toward the low-risk side is best.
Note: Maximum drawdown is computed on a calendar-year-end basis across all asset classes (worst peak-to-trough using year-end NAV/index levels). Intra-year drawdowns, for example the 2020 COVID crash or 1929-32 collapse on a daily basis, were materially deeper than the year-end figures shown. SW Multi Asset AI Flagship Strategy stats reflect its live track record (since inception, Jan 2004); for the 30-year and Since-1928 views, the SW bubble reflects 2004–2025. “Real Estate” is a home-price index (Case-Shiller style); its volatility and drawdown are smoothed and understated versus tradable property. “3-mo T-Bill” is cash. Returns in USD.
Combining a high-return engine with stable bonds can lift your reward per unit of risk above either asset alone. Move the slider to set a blend, both portfolios update side‑by‑side.
Each curve is the set of all 2-asset blends for that pair. The diagonal dashed lines are Capital Allocation Lines (CAL) drawn from the risk-free rate through the current blend, their slope equals the portfolio's Sharpe ratio. Each CAL is tangent to its curve at the maximum-Sharpe blend (the “tangency portfolio”). Numbers use arithmetic mean annual returns over 2004–2025; risk-free rate ≈ 1.75% (avg. 3-mo T-Bill).
Where the previous section blended just two assets, the optimiser now searches across all eligible asset classes simultaneously (every single asset class from the “Return vs. risk” and “How SW Flagship compares across the universe” sections), finding the weight combination that delivers the highest expected return for any chosen level of risk. The curve below is the resulting efficient frontier; the gold marker is the tangency portfolio, the maximum-Sharpe combination. Move the slider to walk along the frontier and watch the weights and risk profile change.
Long-only mean-variance optimisation over eligible asset classes (the single asset classes shown in the “Return vs. risk” scatter and the “How SW Flagship compares” table), using arithmetic mean annual returns, annual volatility and the full pairwise correlation matrix computed over 2004–2025. The 3-month T-Bill is treated as the risk-free asset (rf ≈ 1.75%, the period average). The dashed terracotta curve and diamond mark the classic 60% S&P 500 / 40% 10-yr Treasury portfolio, shown for reference. The purple square marks the family-office reference portfolio (50% MSCI ACWI / 25% Bloomberg U.S. Aggregate / 15% HFRI / 10% cash); it plots inside the frontier, the visual signature of a sub-optimal risk-return trade-off. Composite benchmarks (MSCI ACWI, Bloomberg Aggregate, HFRI, 60/40 and the family-office reference) are reference portfolios built from these same building blocks and are not treated as separate optimisable inputs. Weights are constrained to sum to 100% with no short-selling.
Consider the representative family-office reference portfolio used throughout this paper: 50% global equities (MSCI ACWI), 25% investment-grade bonds (Bloomberg U.S. Aggregate), 15% hedge funds (HFRI) and 10% cash (3-mo T-Bill), rebalanced annually. Over 2004–2025 it compounded at roughly 7.0% per year, with about 9.9% volatility and a −22.4% worst year-end drawdown; a hypothetical $1,000,000 grew to about $4.43M, a Sharpe ratio of 0.58. Now carve out a sleeve for SW Flagship, funded pro-rata from the existing holdings.
| Portfolio (2004–2025) | SW sleeve | Ann. return | Sharpe | Max drawdown | Growth of $1,000,000 |
|---|---|---|---|---|---|
| Existing family-office portfolio | — | 7.0% | 0.58 | −22.4% | $4.43M |
| + 10% SW Flagship | 10% | 8.0% | 0.65 | −21.3% | $5.48M |
| + 20% SW Flagship | 20% | 9.1% | 0.71 | −20.3% | $6.75M |
| + 30% SW Flagship | 30% | 10.1% | 0.76 | −19.2% | $8.28M |
Existing portfolio = 50% global equities / 25% investment-grade bonds / 15% hedge funds / 10% cash. The SW Flagship sleeve is funded pro-rata from the existing holdings. Annualised return is CAGR; Sharpe uses the arithmetic mean annual return and a 1.75% risk-free rate; max drawdown on a calendar-year-end basis.
Replacing one-fifth of a typical family-office portfolio with SW Flagship would historically have raised the annualised return from 7.0% to 9.1%, lifted the Sharpe ratio from 0.58 to 0.71, reduced the worst drawdown from −22.4% to −20.3%, and grown $1,000,000 into $6.75M instead of $4.43M, while leaving 80% of the existing portfolio untouched. The drawdown improves because SW Flagship's mild 2008 result (−11.7%, against deep losses across global equities) cushioned the portfolio in the year that defined its worst decline.
Adding global equity, bond, hedge-fund, 60/40, and family-office reference portfolios alongside the S&P 500 baseline. All figures cover 2004–2025 and are in USD on a calendar-year-end basis.

The goal is not to show SW Flagship has no factor exposure—it does. The goal is to demonstrate the return stream is understood, explainable, and not simply hidden leverage to equities or duration.
SW Flagship carries meaningful equity beta (approximately 0.42 to U.S. equities) but its downside beta is materially lower (0.28), meaning the strategy tends to participate less on the downside than the upside, the asymmetry that underpins the superior drawdown profile.
The residual alpha (approximately 9–10% per annum after stripping systematic factors) reflects the AI-driven multi-asset selection process, not hidden leverage to a single risk premium. This distinguishes it from a leveraged equity or duration play.
Factor betas estimated via OLS regression of annual SW Flagship returns against factor returns 2004–2025. U.S. equity beta: S&P 500 total return. Global equity: MSCI ACWI. Momentum: top-quintile 12-month return premium. Gold/commodities: S&P GSCI. Duration: 10-yr Treasury. Downside beta: regression restricted to S&P 500 negative-return years. Figures are approximate and subject to the limitations of annual data and a 22-observation sample.
The efficient-frontier conclusion depends on historical inputs. Here we stress-test the tangency Sharpe ratios across plausible changes in volatility, correlation, and the risk-free rate. If the case holds under conservative assumptions, the argument becomes meaningfully stronger.

|---|---|---|---|---|
| Baseline | 0.96 | 0.70 | +0.26 | Baseline |
| Combined stress | 0.61 | 0.43 | +0.18 | Case holds |
Across every tested scenario, including higher volatility, rising correlation, higher risk-free rates, and their combination, the SW Flagship + Treasury tangency portfolio maintains a materially higher Sharpe ratio than the S&P 500 + Treasury equivalent. In the combined worst-case stress, the SW advantage narrows but remains +0.18 Sharpe points, still 42% above the S&P baseline.
Importantly, these stress tests are not claims about the future. They illustrate that the historical evidence does not depend on unusually benign inputs: even under materially more adverse assumptions, the risk-adjusted case for SW Flagship as the risky-asset component of a family-office allocation remains intact.
Stress scenarios computed using two-asset mean-variance framework with arithmetic mean returns. All scenarios hold SW Flagship's historical mean return constant (18.36%), as mean-return estimation is a separate, and more uncertain, dimension of model risk. The analysis addresses input sensitivity only; it does not account for regime changes, tail events outside the historical distribution, or changes in the strategy's investment process.
Every strategy has environments where it trails. Presenting them honestly strengthens rather than weakens the case, as institutions that discover gaps independently trust the analysis less.
| Period / Year | SW Flagship | S&P 500 | Difference | Explanation |
|---|---|---|---|---|
| Best S&P-Led Rally Years: when passive U.S. equity dominated | ||||
| 2009 (GFC recovery) | +53.6% | +25.9% | +27.7% | SW outperformed strongly in the recovery. Not a lag year. |
| 2013 (QE taper, risk-on) | +22.5% | +32.2% | −9.7% | Pure large-cap momentum rally; diversified multi-asset trailed a concentrated U.S. equity surge. |
| 2021 (ZIRP mega-cap rally) | +24.3% | +28.5% | −4.2% | Magnificent-7 dominance. Multi-asset approach underweighted the most concentrated momentum trade in U.S. history. |
| 2023 (AI euphoria rebound) | +25.6% | +26.1% | −0.5% | Near-parity; Nvidia-led concentration in S&P 500 narrowed the gap temporarily. |
| 2024 (continued AI rally) | +17.5% | +24.9% | −7.4% | Persistent mega-cap concentration. S&P returned approximately 25% largely driven by a handful of AI-related names. |
| Years SW Flagship Lost Money: negative absolute return years | ||||
| 2022 (inflation shock) | −26.7% | −18.0% | −8.7% | The only year all asset classes fell simultaneously. Rate shock hit bond-like return streams. Worst observed year-end drawdown in the track record. |
| Consecutive S&P Outperformance 2021–2025 (5 of last 8 years) | ||||
| 2021–2025 cumulative | +68% | +141% | −73pp | The S&P 500's 2021–2025 run was driven overwhelmingly by Magnificent-7 concentration. A diversified global multi-asset strategy structurally underweights this concentrated single-country, single-sector bet. This is expected behaviour, not a process failure. |
The S&P 500's 2019–2025 period was defined by an unprecedented concentration of returns in a handful of U.S. technology mega-caps (the "Magnificent 7"). By 2024, these seven companies represented approximately 33% of the S&P 500's market cap. By contrast, the SW Flagship strategy's own average exposure to the same "Magnificent 7" names is roughly 15%, less than half that weight. A broadly diversified global multi-asset strategy that avoids single-name concentration will structurally underperform during periods dominated by concentrated index behaviour. This is a feature, not a bug: the same diversification that limits upside capture in concentrated rallies is what produced a −26.7% maximum drawdown versus the S&P's −36.6% in 2008 and −64.8% over the full century.
Over the full 22-year track record, which includes both the periods of SW strength and the periods of S&P mega-cap dominance, SW Flagship still delivered 3.4× the terminal wealth of passive U.S. equities.
Family offices face real, dated cash calls. A deep drawdown that lasts years is qualitatively different from a shallow one that recovers quickly. The table below compares the full drawdown anatomy for SW Flagship and the S&P 500.

*10-yr U.S. Treasury has not recovered to its 2020 year-end peak on a cumulative total-return basis as of 31 December 2025. Drawdown metrics computed on calendar-year-end NAV/index levels. Intra-year drawdowns on daily data were materially deeper for all three series. "High-water mark" refers to calendar-year-end values only.
SW Flagship's 2022 drawdown of −26.7% was recovered in full within one calendar year (by end of 2023). The S&P 500's 2008 drawdown of −36.6% took four years to recover (until end of 2012). For a family office facing capital calls, distributions, or intergenerational transfers in 2009–2012, the S&P's recovery timeline imposed real, irreversible costs. SW Flagship's ability to recover from its deepest observed drawdown within a single year is, from a liability-matching perspective, at least as important as the drawdown depth itself.
