15 min czytaniaThe Golden Butterfly Portfolio — The Best of Both Worlds
The Golden Butterfly is a five-asset portfolio that blends the safety of Harry Browne's Permanent Portfolio with the growth potential of a more equity-heavy allocation. Created by an anonymous investor known as "Tyler" on the Portfolio Charts website, it allocates 20% each to total stock market, small-cap value stocks, long-term bonds, gold, and short-term bonds.
The Golden Butterfly earned its name by combining the "golden" element (a significant gold allocation) with the "butterfly" concept — a balanced, symmetrical allocation that can adapt to any economic environment. Think of it as the Permanent Portfolio's more growth-oriented sibling.
What makes the Golden Butterfly special is its track record of delivering equity-like returns with dramatically lower volatility. Backtested data shows it has achieved returns close to the S&P 500 while maintaining drawdowns similar to the ultra-conservative Permanent Portfolio — a rare combination that makes it one of the most efficient portfolios ever designed.
Origins and Philosophy
Who Created the Golden Butterfly?
The Golden Butterfly was developed by "Tyler," the creator of PortfolioCharts.com, a popular website that provides free, in-depth analysis of investment portfolios. Tyler's identity remains anonymous, but his work analyzing dozens of portfolio strategies led him to design the Golden Butterfly as an optimized blend.
Tyler's approach was data-driven rather than theoretical. Instead of starting with an economic model (like Dalio's risk parity) or a philosophical framework (like Browne's four environments), Tyler analyzed decades of backtested data to find an allocation that maximized risk-adjusted returns across the widest range of starting years.
The Philosophy: Balance Everything
The Golden Butterfly is built on several interconnected principles:
- No single asset class should dominate — 20% maximum per position means no catastrophic exposure
- Cover all economic environments — like the Permanent Portfolio, but with a growth tilt
- Small-cap value premium capture — adding small-cap value stocks alongside total market provides an extra return source
- Equal simplicity to the Permanent Portfolio — five equal positions are nearly as simple as four
- Minimize worst-case outcomes — optimized for the worst possible retirement start date, not just average returns
Why Add Small-Cap Value?
The addition of small-cap value stocks is the Golden Butterfly's key innovation over the Permanent Portfolio:
- Small-cap value has historically outperformed the broad market by 2-3% annually over long periods (the "size" and "value" premiums identified by Fama and French)
- Small-cap value has different return drivers — these companies are often in distressed or cyclical industries, providing diversification from large-cap growth stocks
- The combination of total market + small-cap value creates a slight growth tilt without dramatically increasing portfolio risk
- During inflationary periods, small-cap value tends to outperform growth stocks, complementing the gold allocation
The Golden Butterfly Allocation
The 20/20/20/20/20 Split
| Asset Class | Allocation | Purpose |
|---|---|---|
| Total US Stock Market | 20% | Broad equity exposure, prosperity |
| Small-Cap Value Stocks | 20% | Enhanced returns, value premium |
| Long-Term Government Bonds | 20% | Recession/deflation protection |
| Gold | 20% | Inflation hedge, crisis insurance |
| Short-Term Government Bonds | 20% | Stability, deflation protection, cash proxy |
How It Compares to the Permanent Portfolio
| Component | Permanent Portfolio | Golden Butterfly | Change |
|---|---|---|---|
| Stocks | 25% (total market) | 40% (20% total + 20% SCV) | ↑ More growth |
| Long-Term Bonds | 25% | 20% | ↓ Slightly less |
| Gold | 25% | 20% | ↓ Slightly less |
| Cash/Short Bonds | 25% | 20% | ↓ Slightly less |
The net effect: The Golden Butterfly reduces each defensive position by 5% and redirects that 15% into small-cap value stocks. This subtle shift meaningfully increases expected returns while maintaining most of the Permanent Portfolio's downside protection.
Historical Performance of the Golden Butterfly
Long-Term Returns (1972–2025)
| Metric | Golden Butterfly | S&P 500 | 60/40 | Permanent Portfolio |
|---|---|---|---|---|
| Annualized Return | ~8.5% | ~10.5% | ~9.0% | ~7.5% |
| Standard Deviation | ~8.5% | ~15.5% | ~10.5% | ~7.5% |
| Max Drawdown | ~-14% | ~-50.9% | ~-32.5% | ~-12.5% |
| Sharpe Ratio | ~0.68 | ~0.45 | ~0.55 | ~0.65 |
| Worst Year | ~-7% | ~-37.0% | ~-22.0% | ~-4% |
| Best Year | ~22% | ~37.6% | ~28.0% | ~18% |
| Positive Years | ~90% | ~75% | ~80% | ~92% |
Note: Performance data is approximate and based on backtested results. Past performance does not guarantee future results.
The Standout Metric: Withdrawal Rates
Where the Golden Butterfly truly excels is in sustainable withdrawal rate analysis. Tyler's research on PortfolioCharts.com shows:
- The Golden Butterfly has supported a ~5% safe withdrawal rate (SWR) over 30-year periods across nearly all historical start dates
- Compare this to the S&P 500's ~4% SWR and the traditional 60/40's ~3.8% SWR
- This means the Golden Butterfly requires approximately 20% LESS savings to achieve the same retirement income vs. a stock-heavy portfolio
Why? Because the low volatility means you rarely sell assets at depressed prices. The "sequence of returns risk" — the danger of a bear market early in retirement — is dramatically reduced.
Performance During Major Crises
| Crisis | Golden Butterfly | S&P 500 | Permanent Portfolio |
|---|---|---|---|
| Dot-Com Crash (2000–2002) | ~+10% cumulative | -49% | ~+15% |
| Global Financial Crisis (2008) | ~-8% | -37% | ~-1% |
| COVID Crash (2020) | ~-8% | -34% | ~-5% |
| 2022 Rate Hikes | ~-12% | -19% | ~-11% |
The Golden Butterfly consistently loses less than the stock market during crashes while recovering faster due to its gold and bond allocations providing rebalancing opportunities.

European/UCITS ETF Implementation
| Asset Class | ETF Ticker | Fund Name | Expense Ratio |
|---|---|---|---|
| Total US Market (20%) | VUAA | Vanguard S&P 500 UCITS ETF (Acc) | 0.07% |
| Small-Cap Value (20%) | ZPRV | SPDR MSCI USA Small Cap Value Weighted UCITS ETF | 0.30% |

| Gold (20%) | SGLD | Invesco Physical Gold ETC | 0.12% |
| Short-Term Bonds (20%) | XEON | Xtrackers II EUR Overnight Rate Swap UCITS ETF | 0.10% |
Total portfolio cost: ~0.13% weighted average expense ratio
US ETF Implementation
| Asset Class | ETF Ticker | Fund Name | Expense Ratio |
|---|---|---|---|
| Total US Market (20%) | VTI | Vanguard Total Stock Market ETF | 0.03% |
| Small-Cap Value (20%) | VBR | Vanguard Small-Cap Value ETF | 0.07% |
| Long-Term Bonds (20%) | TLT | iShares 20+ Year Treasury Bond ETF | 0.15% |
| Gold (20%) | GLD | SPDR Gold Shares | 0.40% |
| Short-Term Bonds (20%) | SHV | iShares Short Treasury Bond ETF | 0.15% |
Implementation Notes
- Small-Cap Value is the trickiest to implement in Europe — ZPRV is the best available UCITS option, though it's less pure than US options like VBR or AVUV
- IUSN (iShares MSCI World Small Cap) is an alternative that covers global small caps but lacks the "value" tilt
- The long-term bond allocation must be 20+ years duration — shorter bonds don't provide the same recession hedge
- Physical gold ETCs (SGLD, IGLN) are preferred over gold mining ETFs

Golden Butterfly vs Permanent Portfolio
The Golden Butterfly is essentially the Permanent Portfolio with a growth upgrade:
- Higher expected returns (~8.5% vs ~7.5%) due to the small-cap value allocation
- Similar drawdown protection (-14% vs -12.5% max drawdown)
- Better sustainable withdrawal rate (~5.0% vs ~4.5%)
- Slightly more complex (5 funds vs 4)
- The tradeoff: slightly less defensive, slightly more equity risk
If you like the Permanent Portfolio concept but want more growth potential, the Golden Butterfly is the natural upgrade.
Golden Butterfly vs All Weather
- Golden Butterfly has more equity exposure (40% vs 30%) and thus higher expected returns
- All Weather has more bond exposure (55% vs 20%) and lower volatility
- Golden Butterfly uses small-cap value for return enhancement; All Weather uses risk parity
- Both include gold (20% vs 7.5%), making both inflation-aware
- Golden Butterfly is simpler — equal weights vs. risk-parity weighting
Golden Butterfly vs 60/40
- Golden Butterfly has dramatically better drawdown protection (-14% vs -32%)
- 60/40 has slightly higher expected returns (~9% vs ~8.5%)
- Golden Butterfly includes gold and split bond duration — 60/40 has no commodity or inflation protection
- Golden Butterfly achieves higher sustainable withdrawal rates despite lower raw returns — volatility matters more than returns for retirement planning
Implementing the Golden Butterfly in Poland
Tax-Advantaged Accounts (IKE/IKZE)
Polish investors should prioritize placing growth assets in tax-advantaged accounts:
IKE (Indywidualne Konto Emerytalne):
- Tax-free capital gains after age 60 (or 55 + 5 years of contributions)
- 2026 contribution limit: ~23,472 PLN
- Best for: Equity allocations (total market + small-cap value) and gold
IKZE (Indywidualne Konto Zabezpieczenia Emerytalnego):
- Tax-deductible contributions + 10% flat tax at withdrawal
- 2026 contribution limit: ~9,388.80 PLN (~14,083.20 PLN for self-employed)
- Best for: Bond allocations (income is tax-advantaged)
Recommended Polish Setup
| Priority | Asset | ETF | Account Type |
|---|---|---|---|
| 1 | Small-Cap Value (20%) | ZPRV | IKE (highest growth potential) |
| 2 | Total US Market (20%) | VUAA | IKE |
| 3 | Gold (20%) | SGLD | IKE or regular |
| 4 | Long-Term Bonds (20%) | DTLA | IKZE |
| 5 | Short-Term Bonds (20%) | XEON | IKZE or regular |
Polish Broker Recommendations
| Broker | IKE | IKZE | ZPRV Available | Gold ETC | Notes |
|---|---|---|---|---|---|
| XTB | ✅ | ✅ | ✅ | ✅ | Commission-free, best overall |
| Bossa (BOŚ) | ✅ | ✅ | ✅ | ✅ | Wide EU ETF access |
| mBank eMakler | ✅ | ✅ | Check | ✅ | Limited small-cap ETFs |
| DM PKO BP | ✅ | ✅ | Check | ✅ | May need to request |
Small-Cap Value Challenge in Poland
The biggest implementation challenge for Polish investors is the small-cap value allocation. Options include:
- ZPRV (SPDR MSCI USA Small Cap Value Weighted) — best available UCITS option
- IUSN (iShares MSCI World Small Cap) — broader but lacks value tilt
- WSML (iShares MSCI World Small Cap UCITS ETF) — similar to IUSN
- Consider allocating to VWCE instead — replacing small-cap value with total world stocks simplifies the portfolio at the cost of losing the value premium
Rebalancing the Golden Butterfly
Rebalancing Strategy
The Golden Butterfly follows the same approach as the Permanent Portfolio:
- Band rebalancing: Rebalance when any asset exceeds 25% or drops below 15% of the portfolio
- Annual rebalancing: Simply reset to 20/20/20/20/20 once per year
- Cash flow rebalancing: Direct new investments to whichever position is most underweight
Annual rebalancing is the simplest and works well. The equal-weight structure means drift is easy to spot — just check if any position has moved more than a few percentage points from 20%.
Tax-Efficient Rebalancing
Within IKE/IKZE accounts, rebalancing is tax-free — this is a major advantage. For positions held in regular taxable accounts:
- Use new contributions to rebalance rather than selling overweight positions
- If you must sell, prioritize lots with losses to offset gains
- Consider XEON (short-term bonds) in a regular account since its returns are minimal and tax impact is low
Who Should Use the Golden Butterfly?
Ideal For
- Investors who like the Permanent Portfolio but want more growth — the 40% equity allocation provides meaningfully higher long-term returns
- Early retirees and FIRE practitioners — the high sustainable withdrawal rate (~5%) means you need less saved to retire
- Risk-averse investors who still want decent returns — the -14% max drawdown is remarkably low for a portfolio returning ~8.5%
- Long-term investors who value simplicity — five equal-weight positions are easy to understand and maintain
- Factor investors — the small-cap value tilt adds exposure to well-documented return premiums
Less Ideal For
- Maximum growth seekers — if you can handle 50%+ drawdowns, a 100% equity portfolio will likely outperform over 30+ years
- Investors who don't believe in the value premium — if small-cap value doesn't outperform going forward, the Golden Butterfly loses its edge over the Permanent Portfolio
- Those who find 5 positions too complex — the Permanent Portfolio (4 positions) or Boglehead (3 positions) are simpler alternatives

Frequently Asked Questions
Is the small-cap value premium still real?
Academic research continues to support the small-cap value premium, though it has been weaker in recent decades. Fama and French's factor model shows that value and size premiums have persisted across global markets for over a century. However, from 2010-2020, growth stocks dramatically outperformed value. Many researchers argue the premium is cyclical, not dead — and that the recent underperformance actually makes value stocks cheaper and thus more likely to outperform going forward.
Can I use a global stock fund instead of US-only?
Yes, using VWCE (Vanguard FTSE All-World) for the total market portion adds international diversification. Tyler's original design used US stocks because the backtesting data was readily available, but global equity exposure is arguably better for non-US investors. The Golden Butterfly's principles don't require US-only stocks — any broad equity index works.
How does the Golden Butterfly handle high inflation?
Better than most portfolios. The 20% gold allocation provides direct inflation protection, small-cap value stocks tend to outperform during inflationary periods (their businesses often have real asset backing), and long-term bonds — while they suffer from rate increases — comprise only 20% of the portfolio. The short-term bond allocation is relatively unaffected by inflation.
What's the minimum amount to start?
With fractional share investing at brokers like XTB, you can start with as little as 500 PLN. However, for meaningful diversification across five positions, a starting amount of at least 5,000 PLN (1,000 PLN per position) is practical. If starting smaller, consider beginning with three positions (VWCE + SGLD + XEON) and adding the others as your portfolio grows.
Is the Golden Butterfly better than the All Weather Portfolio?
It depends on your priorities. The Golden Butterfly offers higher expected returns (~8.5% vs ~7%) with similar maximum drawdowns (~14% vs ~15%). However, the All Weather Portfolio uses risk parity which may provide better balance in extreme scenarios. The Golden Butterfly's advantage is its simplicity and higher growth potential; the All Weather's advantage is its theoretical foundation in economic scenario planning.
Conclusion
The Golden Butterfly is one of the most efficient portfolios ever backtested. It achieves the rare combination of equity-like returns (~8.5%) with bond-like volatility (max drawdown ~14%), making it an exceptional choice for investors who want growth without the stomach-churning drops of conventional stock-heavy portfolios.
The portfolio's secret weapon is its simplicity and balance. Five equal-weight positions covering growth (stocks + small-cap value), safety (short-term bonds), crisis protection (gold), and recession hedging (long-term bonds) ensure you're prepared for every economic environment.
For Polish investors pursuing FIRE or long-term wealth building, the Golden Butterfly's high sustainable withdrawal rate (~5%) means you can retire with less savings. Combined with IKE/IKZE tax advantages and low-cost European ETFs, it's one of the most practical and efficient portfolio strategies available today.
