Can the Golden Butterfly really match stocks with half the pain?
The Golden Butterfly grew out of the Portfolio Charts community with an ambitious goal: keep pace with stocks over the long run while cutting the gut-wrenching declines roughly in half. It splits money five ways — total-market and small-cap-value stocks, long- and short-term Treasuries, and gold — so that whatever the economy throws at it, something in the mix is usually working.

What an investor actually experiences: drawdowns
The Golden Butterfly is one of the calmest portfolios you can build, and the drawdown chart proves it: its worst fall was just -17.8%, about a third of the S&P 500's -50.8%. It also healed quickly — roughly 29 months back to even, versus 52 for stocks alone.
A loss under 20% is the kind most investors can live through without losing sleep or selling in a panic. For money attached to a real goal — a home, a child's college fund, a retirement date within reach — that shallow, short decline is exactly what keeps a bad market from derailing the plan.
Results
| Statistic | S&P 500 (SPY) | Golden Butterfly |
|---|---|---|
| CAGR | 8.8% | 7.9% |
| Annualized volatility | 15.0% | 8.1% |
| Sharpe ratio | 0.64 | 0.98 |
| Sortino ratio | 0.96 | 1.60 |
| Max drawdown | -50.8% | -17.8% |
| Longest drawdown (months) | 52 | 29 |
| Growth of $10,000 | $83,976 | $67,497 |
The Golden Butterfly grew at 7.9% a year, turning $10,000 into $67,497 over about 25 years — remarkably close to the S&P 500's $83,976, but earned with a fraction of the stress (volatility of 8.1% versus 15.0%).
That combination makes its risk-adjusted numbers stand out: a Sharpe ratio of 0.98 and a Sortino of 1.60, far above the S&P's 0.64 and 0.96. In plain terms, it captured almost all of the growth while taking on much less risk — one of the most efficient trade-offs in this entire set of portfolios.
Figures are computed from monthly adjusted closing prices over Sep 2000–Jul 2026. Drawdowns are measured at month-end and so understate intra-month extremes.
Methodology
The two instruments
- VTI — Vanguard Total Stock Market ETF
- The broad US stock market — the main growth driver.
- IJS — iShares S&P Small-Cap 600 Value ETF
- Smaller US companies trading cheaply. This 'small-cap value' tilt has historically added return, though with extra bumpiness.
- TLT — iShares 20+ Year Treasury Bond ETF
- Long-term US government bonds — strong protection when growth or inflation falls, but very rate-sensitive.
- SHY — iShares 1-3 Year Treasury Bond ETF
- Short-term US government bonds that behave much like cash — the portfolio's stable anchor.
- GLD — SPDR Gold Shares
- Physical gold, a hedge against inflation and currency stress that often moves independently of stocks and bonds.

Advantages
- Smooth, consistent ride
- Spreading money across five assets that respond to different conditions has historically produced shallower declines and fewer scary years than an all-stock portfolio, without giving up much growth.
- Barbell of safety and growth
- Pairing short-term Treasuries (very safe) with long-term Treasuries and a value-stock tilt (higher potential) covers both calm and stressed markets rather than betting on one.
- A true inflation hedge
- The 20% in gold gives the portfolio a defense against inflation shocks that hurt stocks and bonds together — a gap a plain stocks-and-bonds mix leaves open.
Disadvantages and risks
- Lags in strong bull markets
- With only 40% in stocks, the portfolio trails a stock-heavy one when equities are running hot, which can test an investor's patience.
- Big bet on gold
- A full fifth in gold is unusually high. Gold can go many years producing little, so this allocation is a conviction bet that will sometimes look wrong.
- Small-cap value can underperform for years
- The value tilt has historically paid off over the very long run, but it has endured long stretches of lagging the broad market.

- What's in the Golden Butterfly portfolio?
- An equal five-way split — 20% each in US total-market stocks, small-cap value stocks, long-term Treasuries, short-term Treasuries, and gold — rebalanced yearly. It was popularized by the Portfolio Charts website.
- Who is the Golden Butterfly best for?
- It has historically delivered strong risk-adjusted returns with notably shallow declines. It suits investors who want most of the stock market's growth with a much calmer ride, and who can accept lagging in roaring bull markets.
- How is the Golden Butterfly different from the Permanent Portfolio?
- It is the Permanent Portfolio tilted toward growth: it splits the stock slice into total-market and small-cap value and swaps some cash for short-term Treasuries, aiming for higher long-run returns while keeping the four-way balance.
