Portfolio Stress Testing
The Regime Change Simulator
Pick a scenario, move one slider, and see what an alternatives sleeve does to the same $1,000,000 portfolio.
- 1. Choose a scenario
- 2. Set the alternatives allocation
- 3. Read the outcome
Step 1 · Choose a scenario
The decade ahead (2026–2035) — J.P. Morgan 2026 Long-Term Capital Market Assumptions. J.P. Morgan's Long-Term Capital Market Assumptions: modest US equity returns, meaningfully higher bond yields, and a structurally higher inflation floor than the 2010s.
Step 2 · Add alternatives
Of a $1,000,000 portfolio in hedge funds, private equity and private credit.
15% hedge funds · 9% private equity · 6% private credit
Step 3 · Set the stock / bond split
Resulting portfolio mix
Starting value is fixed at $1,000,000 for illustration — scale the results to your own portfolio. The sleeve splits 50% hedge funds · 30% private equity · 20% private credit.

These figures represent projections, not actual or guaranteed results. The values displayed above are hypothetical illustrations derived from third-party capital market assumptions and do not represent the performance of any actual account or investment. There is no assurance that the returns, growth, or incremental value attributed to the alternatives sleeve will be achieved, and actual results may differ materially from those shown.
Ten-year path — The decade ahead (2026–2035) — J.P. Morgan Long-Term Capital Market Assumptions (default)
Both lines are nominal dollars, before inflation. The teal line shows your current mix including the alternatives sleeve.
Your portfolio (nominal)
Classic 60/40, no alternatives
Both lines represent projected outcomes under the assumptions selected above and do not represent actual or realized performance.
What the two lines mean
Your portfolio (nominal): The projected dollar value of your current mix (stocks, bonds, and any hedge fund / private equity / private credit sleeve) compounded at the regime's assumed annual returns. Nominal means before inflation — raw dollars, not buying power.
Classic 60/40, no alternatives: A baseline 60% stocks / 40% bonds portfolio under the selected regime — shown for comparison (nominal dollars).
How alternatives are modeled in the J.P. Morgan forward-looking regime
With US equities projected in the mid-single digits and bonds only a partial cushion, J.P. Morgan's Long-Term Capital Market Assumptions project lower returns for a traditional 60/40 portfolio than were realized during much of the 2010s. Under the assumptions used in this scenario, the alternatives sleeve is modeled as contributing additional return from private equity, hedge funds, and private credit compared with the traditional 60/40 baseline.
Why the decade ahead is different
120%
Projected federal debt vs. the economy by 2036 — an all-time record (CBO, Feb 2026)
$2.1T
Annual federal interest bill by 2036 — double today's, pressuring rates higher
2%
Trend US real GDP growth — roughly half the post-war average, compressing traditional equity return runway
~4.3%
Projected average 10-yr Treasury yield — the zero-rate decade isn't coming back
Hedge Funds — a potential shock absorber
In 2022, diversified hedge fund strategies lost roughly 4% while a traditional 60/40 portfolio lost approximately 16%. In that environment, hedge fund returns were less negative than stocks and bonds.
Private Equity — exposure beyond public markets
With fewer companies remaining public for as long as in prior decades, private equity provides exposure to businesses that are not accessible through public equity markets.

Methodology (inputs, sources and formulas)
Data sourcing. Crystal Capital Partners does not publish its own capital market assumptions. All forward-looking stock, bond, and inflation inputs are drawn from third-party providers — J.P. Morgan (default), BlackRock, and Mercer — and can be swapped via the scenario picker. Historical decades and stress-replay periods use realized index returns. Alternatives sleeve returns are illustrative building-block estimates drawn from published third-party ranges; Crystal does not forecast HF or PE returns internally.
Forward-looking inputs by provider (annual, nominal)
| Provider | US Equity | US Agg Bonds | Inflation | Hedge Funds | Private Equity | Private Credit |
|---|---|---|---|---|---|---|
| J.P. Morgan LTCMA (default) | 6.7% | 4.6% | 2.4% | 5.6% | 9.9% | 7.8% |
| BlackRock Investment Institute | 6.2% | 4.5% | 2.5% | 5.5% | 9.5% | 7.5% |
| Mercer Capital Market Assumptions | 6.5% | 4.4% | 2.5% | 5.8% | 9.7% | 7.6% |
HF, PE, and Private Credit figures reflect each provider's most recent published long-term capital market assumptions for diversified hedge funds, US large-cap buyout private equity, and direct lending / private credit. Values are rounded and shown as nominal, net-of-fee where the provider reports on that basis.
Historical benchmarks (realized, annualized)
| Period | Stocks | Bonds | Inflation |
|---|---|---|---|
| The 2010s (2012–2021) | 11.5% | 3.5% | 1.8% |
| The lost decade (2000–2009) | −0.9% | 6.3% | 2.5% |
Alternatives sleeve — forward-looking (illustrative, nominal, net): hedge funds 7.0%/yr, private equity 10.0%/yr, private credit 9.0%/yr. These are mid-range building blocks consistent with published third-party ranges (e.g. J.P. Morgan Long-Term Capital Market Assumptions, BlackRock, Mercer) rather than Crystal Capital forecasts. Historical and stress-replay regimes replace these with realized benchmark returns (see next table). The alts slider carves proportionally from both stocks and bonds and splits 50% HF · 30% PE · 20% PC.
Scenarios & historical benchmarks (realized, annualized)
| Scenario | Stocks (S&P 500 TR) | Bonds (Bloomberg U.S. Agg) | Inflation (CPI) | Hedge Funds (HFRI) | Private Equity (Cambridge) | Private Credit (CDLI) |
|---|---|---|---|---|---|---|
| The 2010s (2010–2019) | 11.5% | 3.5% | 1.8% | 5.0% | 14.2% | 9.4% |
| The lost decade (2000–2009) | −0.9% | 6.3% | 2.5% | 6.3% | 7.5% | 10.0%1 |
| Dot-com replay (2000–2002 avg) | −14.6% | 10.0% | 2.5% | 3.0% | −7.0% | n/a2 |
| GFC replay (2007–2009 avg) | −37.0% | 5.2% | 3.8% | −0.5% | −5.0% | 2.0% |
| COVID replay (full-year 2020) | −34.0% | 8.0% | 1.2% | 11.8% | 28.0% | 5.5% |
| 2022 stress cushion | −18.1% | −13.0% | 6.5% | −4.1% | −2.0% | −1.5% |
1 CDLI history begins Sept 2004; pre-2004 private credit is estimated from BDC and leveraged-loan proxies.
2 Dot-com window pre-dates CDLI entirely — for that scenario the sleeve reweights to 62.5% HF / 37.5% PE and PC is shown as n/a.
Sources: HFRI Fund Weighted Composite Index (Hedge Fund Research); Cambridge Associates US Private Equity Index (pooled net horizon returns); Cliffwater Direct Lending Index (CDLI).
Stress-replay 2022 cushion inputs: stocks −18.1% (S&P 500 TR), bonds −13.0% (Bloomberg U.S. Agg), hedge funds −4.1% (HFRI FW), PE −2.0% (Cambridge, appraisal-based/smoothed), PC −1.5% (CDLI). Dot-com (2000–2002), GFC (2007–2009), and COVID (full-year 2020) replays use annualized index returns over each window.
Formulas
- Weights with alts sleeve a: equity = E×(1−a), bonds = (1−E)×(1−a), HF = 0.50·a, PE = 0.30·a, PC = 0.20·a. When PC benchmark data is unavailable (dot-com), the sleeve reweights to HF = 0.625·a, PE = 0.375·a.
- Portfolio nominal return: weighted average of the four.
- Real return: (1 + nominal) / (1 + inflation) − 1.
- 10-year values: compounded year-by-year. For forward-looking and historical-decade regimes, the annual return is applied to all 10 years. For stress replays (dot-com, GFC, COVID, 2022), year 1 uses the scenario's crash-year returns and years 2–10 compound the JPM forward-looking baseline — a shock followed by a normal recovery, not a decade of repeated crashes.
- Stress loss: P × Σ(weighti × stress returni).
Because the alts sleeve is carved proportionally from stocks and bonds, and bonds were nearly as bad as stocks in 2022, the stress cushion at modest alts weights is small. Under the assumptions used in the model, changes in projected return have a larger impact on results than changes in projected drawdowns. The tool's stronger effect is the return pickup rather than drawdown protection.
For financial professional use only. Hypothetical illustration for educational purposes only; not investment advice, a performance projection, or an offer of any security. Crystal Capital Partners does not produce its own capital market assumptions; forward-looking return and inflation inputs are sourced from third-party providers (J.P. Morgan Long-Term Capital Market Assumptions, BlackRock Investment Institute, Mercer) as selected in the scenario picker, and will not be realized as shown. Stress-scenario figures are approximate index results (S&P 500 total return, Bloomberg U.S. Aggregate, HFRI Fund Weighted Composite); private equity figures reflect reported (appraisal-based) valuations, which understate volatility. Alternatives sleeve returns are illustrative building blocks drawn from published third-party ranges, not Crystal Capital forecasts. Alternative investments are speculative, illiquid, involve high fees and risk of loss, and are suitable only for qualified investors. Diversification does not ensure a profit or protect against loss.
