Results from 1% to 20%, drawdowns and method. --- **Cory Klippsten** · November 12, 2026 Adding 2.5% Bitcoin to a 60/40 portfolio raised its annual return from 9.1% to 11.2% between 2014 and 2025, while volatility rose only from 10.3% to 10.6%. A 20% Bitcoin allocation returned 24.1% a year over the same 12 years, but its worst decline was 34.1%, against 20.9% for the plain 60/40. Those are the results of a backtest Swan ran on a standard stock and bond portfolio, with Bitcoin rebalanced back to its target every quarter. If you're deciding how much Bitcoin to hold in a portfolio, this page gives every result from 1% to 20%, the method, the drawdowns, what to consider near retirement, and how the numbers compare with what BlackRock, Fidelity, Morgan Stanley, Vanguard, Bitwise and Morningstar have published. Data runs through December 31, 2025. I hear one objection all the time: "I've been crushing it with stocks, and Bitcoin is basically a tech stock, so why bother?" If that sounds familiar, here is what happened when we ran the numbers. ![Line chart: $1 million in a 60/40 portfolio grew to $2.84 million from 2014 to 2025, or $3.56 million with 2.5% in Bitcoin, about $724,000 more](https://www.datocms-assets.com/56652/1794503415-bitcoin-60-40-portfolio-1m-growth-2014-2025.png?auto=format) Swan backtest. Hypothetical, not investment advice. ## What happens when you add Bitcoin to a 60/40 portfolio? Over 12 years, a small Bitcoin allocation raised returns a lot and risk a little, and a large one raised both. Results for 2014 through 2025, starting with $1 million: - **60/40, no Bitcoin:** 9.1% a year, 10.3% volatility (annualized standard deviation), Sharpe ratio 0.71, $1 million grew to $2.84 million. - **2.5% Bitcoin:** 11.2% a year, 10.6% volatility, Sharpe ratio 0.88, $1 million grew to $3.56 million. - **20% Bitcoin:** 24.1% a year, 18.7% volatility, Sharpe ratio 1.15, $1 million grew to $13.32 million. ### 2.5% Bitcoin: more return for almost no extra volatility With 2.5% in Bitcoin, $1 million grew to $3.56 million instead of $2.84 million. That is about $724,000 more, and a 39% increase in investment gains, with Bitcoin reset to its 2.5% target every quarter. Volatility barely moved. The annual return rose by more than two percentage points, and annualized volatility rose by 0.3 percentage points. The Sharpe ratio rose from 0.71 to 0.88. Even at that small weight, Bitcoin's returns made a real contribution, while its low correlation with the S&P 500 limited the increase in portfolio volatility. ### 20% Bitcoin: much higher returns, bigger swings At 20% Bitcoin, the annualized return rose to 24.1%, and $1 million grew to $13.32 million. Annualized volatility climbed to 18.7%, about 80% higher than the original portfolio. The Sharpe ratio, though, rose to 1.15, against 0.88 for the 2.5% allocation and 0.71 without Bitcoin. That is substantially more return for each unit of volatility. If you had the stomach to stay invested and keep rebalancing through the bigger swings, you were well rewarded over those 12 years. ## What about 1%, 5% or 10% Bitcoin? Smaller allocations show the same pattern: each step up added return and a little risk. Our backtest tested 2.5% and 20%; Bitwise's February 2026 study of a 60% global stock and 40% bond portfolio, also rebalanced quarterly from 2014 to 2025, fills in 1% and 5%: - **No Bitcoin (Bitwise):** 7.10% a year, 8.48% volatility, Sharpe ratio 0.551, maximum drawdown 22.07%. - **1% Bitcoin (Bitwise):** 7.94% a year, 8.57% volatility, Sharpe ratio 0.643, maximum drawdown 22.73%. - **2.5% Bitcoin (Bitwise):** 9.18% a year, 8.86% volatility, Sharpe ratio 0.762, maximum drawdown 23.72%. - **5% Bitcoin (Bitwise):** 11.21% a year, 9.68% volatility, Sharpe ratio 0.907, maximum drawdown 25.35%. A 10% allocation wasn't tested in either study. It would sit between the 5% results above and our 20% results, which returned 24.1% a year with a 34.1% worst decline. ## Is it too late to add Bitcoin? Results from 2020 to 2025 No, at least over the last six years. Starting in 2020 cut the 20% portfolio's return but still beat the plain 60/40 by a wide margin. To test how much of the result depended on getting into Bitcoin in 2014, we dropped the first six years, including the 2017 bull run, and started again at the beginning of 2020. Same investments, same quarterly rebalancing, through the end of 2025. Results for 2020 through 2025: - **60/40, no Bitcoin:** 9.6% a year, Sharpe ratio 0.57, $1 million grew to $1.73 million. - **2.5% Bitcoin:** 11.3% a year, volatility up less than 0.5 percentage points, Sharpe ratio 0.67, $1 million grew to $1.9 million. - **20% Bitcoin:** 22.3% a year, 19.3% volatility, Sharpe ratio 1.0, $1 million grew to $3.36 million. ![Bar chart of annualized returns. 60/40: 9.1% (2014 to 2025), 9.6% (2020 to 2025).

Hypothetical, not investment advice. ## How bad were the drawdowns? The 20% Bitcoin portfolio fell 34.1% from its peak at its worst, from November 2021 to November 2022. A $1 million balance at that peak would have dropped to about $659,000. Drawdowns matter because you may need cash from your portfolio along the way, for living expenses, college, a house or anything else. If that need comes during a sell-off, you could be forced to sell at depressed prices. The largest drop from peak to low for each portfolio, 2014 through 2025: - **60/40, no Bitcoin:** 20.9%, February to March 2020 (the COVID crash). It fell 20.8% again in 2022. - **2.5% Bitcoin:** 21.8%, December 2021 to October 2022. - **20% Bitcoin:** 34.1%, November 2021 to November 2022. So a 2.5% allocation added less than one percentage point to the worst decline. A 20% allocation added about 13 points. As Bitcoin matures, future returns could be lower. Volatility and drawdowns could also get smaller. ![Drawdown chart, 2014 to 2025. Worst decline: 60/40 20.9% (Feb to Mar 2020), 2.5% Bitcoin 21.8% (Dec 2021 to Oct 2022), 20% Bitcoin 34.1% (Nov 2021 to Nov 2022)](https://www.datocms-assets.com/56652/1794503416-bitcoin-60-40-drawdowns-2014-2025.png?auto=format) Swan backtest. Hypothetical, not investment advice. ## Should you add Bitcoin if you're near retirement? The closer you are to needing the money, the more the drawdown numbers matter. A 34.1% decline is hard to wait out if you have to sell to cover living expenses, while a 21.8% decline (2.5% Bitcoin) was close to the plain 60/40's 20.9%. Three things to weigh: - **Size:** in our test, a small allocation (2.5%) changed the worst decline by less than one percentage point. A large one (20%) added about 13 points. - **Timing of withdrawals:** the 20% portfolio's worst stretch ran from November 2021 to November 2022. Money needed during a period like that would have been sold near the low. - **What large firms suggest:** Morgan Stanley recommends zero for conservative investors focused on income or wealth preservation, and 2% for balanced growth portfolios. This is not advice for your situation. A financial advisor can size an allocation around your withdrawal needs. ## Is Bitcoin just a tech stock? No. Over 2014 through 2025, the correlation of Bitcoin's daily returns with the S&P 500 was 0.21. Tech stocks (the Nasdaq-100) came in at 0.93, close to moving in lockstep with the market. The correlation has risen in recent years but stayed far below tech: - **Bitcoin vs. S&P 500, daily returns:** 0.21 (2014 to 2025), 0.38 (2020 to 2025). - **Nasdaq-100 vs. S&P 500, daily returns:** 0.93 (2014 to 2025), 0.94 (2020 to 2025). - **Monthly returns since 2020:** Bitcoin 0.55, Nasdaq-100 0.92. That low correlation is why a small Bitcoin position raised the portfolio's return without raising its volatility by much. A position in another tech stock would mostly move with what you already own. ![Bar chart: correlation of daily returns with the S&P 500. Nasdaq-100 0.93 (2014 to 2025) and 0.94 (2020 to 2025); Bitcoin 0.21 and 0.38](https://www.datocms-assets.com/56652/1794503416-bitcoin-vs-nasdaq-correlation-with-sp500.png?auto=format) Swan backtest. Hypothetical, not investment advice. ## Why does rebalancing matter? Quarterly rebalancing forced the portfolio to sell Bitcoin after big rallies and buy it after declines, and the results assume you did both every time. Take the fourth quarter of 2017. Bitcoin grew from its 20% target to almost 46% of the portfolio by the end of the quarter. The model then sold enough Bitcoin to bring it back to 20% and put the proceeds into stocks and bonds. After quarters when Bitcoin had fallen below its target, the model bought more. Rebalancing also keeps the risk you signed up for. Without it, a 20% Bitcoin position can drift to half the portfolio after a strong run. Where you hold it matters for taxes. In a taxable account, each rebalancing sale can trigger capital gains tax, which this backtest does not include. Inside an IRA, investments are tax-deferred, so rebalancing trades there don't create a tax bill in the year you make them. You can hold real Bitcoin in a [Bitcoin IRA](https://www.swanbitcoin.com/industry/bitcoin-iras/). ## How much of your portfolio should be in Bitcoin? There is no single right number: it depends on how large a drawdown you can sit through without selling. Our results show the trade-off. A 2.5% allocation raised returns with almost no added volatility, while 20% raised returns much further but deepened the worst decline from 20.9% to 34.1%. What large asset managers have published: - **BlackRock (December 2024):** "We believe a 1-2% allocation to bitcoin is a reasonable range for a multi-asset portfolio." - **Bitwise (February 2026):** a 60% global stock and 40% bond portfolio with 2.5% Bitcoin, rebalanced quarterly from 2014 to 2025, returned 9.18% a year instead of 7.10%. Its Sharpe ratio rose from 0.551 to 0.762 and its maximum drawdown from 22.07% to 23.72%. - **Morgan Stanley (Global Investment Committee):** up to 4% in "opportunistic growth" portfolios, 3% in "market growth", 2% in "balanced growth", and zero for conservative investors focused on income or wealth preservation. It calls regular rebalancing "crucial." - **Vanguard:** since December 2025, Vanguard lets brokerage clients trade select third-party Bitcoin ETFs and mutual funds, but it does not offer its own and "has no plans to launch" any. It focuses its own products on assets that "generate cash flow." - **Fidelity Digital Assets (March 2026):** in its analysis, "the portfolio with the highest Sharpe Ratio includes 9.4% bitcoin and 0% bonds." Fidelity notes it can't give specific recommendations. - **Morningstar (January 2024):** "5% Is the Tipping Point," the level where the largest shifts in total portfolio risk toward Bitcoin begin. Its 25% Bitcoin portfolio had a maximum drawdown of 36% from 2014 to 2023. - **QuantPedia (February 2024):** suggests capping the allocation at "maximally 2-3% of the portfolio." Our 2.5% results line up with Bitwise's: a few points more return for a small rise in volatility and drawdown. Our returns are higher in every row, and the main difference is the stock fund. We used the S&P 500 (SPY); Bitwise used global stocks (VT) and a different bond fund (BND). Logically, investors ought to judge Bitcoin the same way they judge any addition to their holdings: by what it contributes to the whole portfolio on a risk-adjusted basis. I'm also very understanding of families and business owners who hesitate. Bitcoin is relatively new, we didn't grow up with it, and that means learning about it as we buy it. ## Should the Bitcoin come from stocks or bonds? Can it replace bonds? In this backtest it came from both, in the same 60/40 proportion. A 2.5% Bitcoin portfolio held 58.5% in the S&P 500 fund and 39% in the bond fund. A 20% Bitcoin portfolio held 48% and 32%. Taking the Bitcoin only from bonds would leave the stock weight at 60% and give a riskier portfolio than the one tested here. Taking it only from stocks would give a less risky one. Morgan Stanley suggests funding a position "from risky assets, not cash." Can Bitcoin replace bonds entirely? This backtest didn't test that. In our results, Bitcoin replaced a slice of both stocks and bonds, not the whole bond side, and the 20% version still had a 34.1% worst decline. ## How do you hold the Bitcoin part of a portfolio? You can hold real Bitcoin or a spot Bitcoin ETF. An ETF tracks the price inside a brokerage account but charges a management fee every year, and you can't withdraw or self-custody it. Real Bitcoin can be held in your own wallet or with a custodian, including inside an IRA. - **Fees:** US spot Bitcoin ETF expense ratios ran from 0.14% to 1.5% a year in October 2026. See [Bitcoin ETF fees, lowest to highest](https://www.swanbitcoin.com/education/bitcoin-etf-fees/) and [IBIT vs. GBTC](https://www.swanbitcoin.com/analysis/ibit-vs-gbtc/). - **Retirement accounts:** here is [why Bitcoin suits an IRA](https://www.swanbitcoin.com/investing/why-bitcoin-is-the-ultimate-asset-for-your-ira/). - **Building the position:** buying a fixed amount on a schedule is called [dollar-cost averaging](https://www.swanbitcoin.com/investing/dollar-cost-average/). - **Custody:** for long-term holdings, see [Bitcoin cold storage](https://www.swanbitcoin.com/education/bitcoin-cold-storage/).

In our backtest, 2.5% raised the 12-year annual return from 9.1% to 11.2% with almost no added volatility. Larger allocations raised returns further but with much deeper drawdowns. ### What percentage of net worth should be in Bitcoin? No firm publishes a net worth figure; the guidance above is a share of an investment portfolio. A simple check: if Bitcoin fell by half, a 5% position would reduce the total by about 2.5%, and a 20% position by about 10%. Size it so that drop wouldn't force you to sell. ### My financial advisor says no Bitcoin. What does the research say? Large firms have moved. BlackRock calls 1% to 2% reasonable, Morgan Stanley's Global Investment Committee suggests up to 4% in growth portfolios, and Vanguard has allowed Bitcoin ETFs on its brokerage platform since December 2025. In our backtest, 2.5% Bitcoin raised a 60/40's Sharpe ratio from 0.71 to 0.88. Bring those figures to the conversation. ### Should Bitcoin go in an IRA or a taxable account? Inside an IRA, investments are tax-deferred, so selling Bitcoin to rebalance doesn't create a tax bill that year. In a taxable account, rebalancing sales can trigger capital gains tax. Swan offers a [Bitcoin IRA](https://www.swanbitcoin.com/bitcoin-ira/) that holds real Bitcoin. ### Is 10% in Bitcoin too much? It depends on whether you could hold through a large decline without selling. In our test, a 20% allocation fell 34.1% at its worst (November 2021 to November 2022), against 20.9% for a plain 60/40. Bitwise found a 25.35% worst decline at 5%. A 10% allocation would sit between those cases. ### Does a 1% or 2.5% Bitcoin allocation make a difference? Yes. In our 2014 to 2025 backtest, 2.5% Bitcoin turned $1 million into $3.56 million instead of $2.84 million, about $724,000 more, while volatility rose only from 10.3% to 10.6%. ### Is the 60/40 portfolio dead? No. A plain 60% S&P 500 and 40% US bond portfolio returned 9.1% a year from 2014 to 2025 and 9.6% a year from 2020 to 2025 in our backtest. Adding Bitcoin raised the return in both periods. ### What is a 40/60 portfolio? A 40/60 portfolio holds 40% in stocks and 60% in bonds, the reverse of a 60/40. It is more conservative, so it usually has lower returns and smaller declines. ### Is Bitcoin correlated with the stock market? Only loosely. Bitcoin's daily returns had a 0.21 correlation with the S&P 500 from 2014 to 2025 and 0.38 from 2020 to 2025. The Nasdaq-100 came in at 0.93 and 0.94. ### How often should you rebalance a Bitcoin allocation? This backtest rebalanced quarterly, selling Bitcoin after rallies and buying after declines. In late 2017, a 20% target had grown to almost 46% of the portfolio before rebalancing brought it back. Rebalancing in a taxable account can trigger capital gains tax. ### What would $1 million in a 60/40 portfolio with 20% Bitcoin be worth? In our hypothetical backtest, $1 million invested at the start of 2014 grew to $13.32 million by the end of 2025, against $2.84 million for a plain 60/40. Started in 2020, it grew to $3.36 million, against $1.73 million. Past performance is not indicative of future results. ## How we ran the backtest - **Portfolios:** 60% S&P 500 (SPY) and 40% US total bond market (VBTLX), then the same portfolio with 2.5% and 20% Bitcoin. The money for Bitcoin came out of stocks and bonds in the same 60/40 proportion. - **Periods:** January 2014 through December 2025 (12 years) and January 2020 through December 2025 (6 years). - **Prices:** daily closing prices, with fund distributions reinvested. Bitcoin prices from Coin Metrics. - **Rebalancing:** every quarter, back to the target weights. - **Volatility:** annualized standard deviation of daily returns. - **Sharpe ratio:** the portfolio's return minus the risk-free rate (the US three-month Treasury yield), with the average of those excess returns divided by their standard deviation. - **Correlation:** daily returns on US trading days, SPY (S&P 500), QQQ (Nasdaq-100) and Coin Metrics (Bitcoin). - **Limits:** hypothetical results before personal taxes and trading costs.
