Bitcoin vs the S&P 500

Warren Buffett says index funds are the best strategy for most investors. He's probably right for most people. Bitcoin is the highest-performing asset of the past fifteen years. Here is the honest comparison for Canadians: returns, volatility, correlation, inflation hedging, Canadian tax treatment, ETF access, and a defensible framework for sizing both positions.

Warren Buffett says index funds are the best strategy for most investors. He's probably right for most people. But the S&P 500 has never outperformed Bitcoin over any 10-year window. Here's the complete picture.

Last updated: June 2026 · Reading time: ~13 minutes

Index funds are the canonical answer in modern personal finance. When in doubt, buy the S&P 500, a low-cost, diversified fund tracking the 500 largest US companies. Warren Buffett has recommended it to his own heirs. Most Canadian financial planners recommend it as the default portfolio for most investors.

The advice is well-grounded. The S&P 500 has returned approximately 10.8% annually in USD over its full history (1926-2026). It's diversified, liquid, cheap (0.03-0.20% MER for major ETFs), and backed by real businesses generating real earnings. For a Canadian investor who just wants to grow wealth without complexity, it's hard to argue against the S&P 500 as a core holding.

But here's the data that rarely makes it into the standard advice: Bitcoin has outperformed the S&P 500 over every measured 10-year window since Bitcoin existed. Not by a little, by multiples. And the structural reasons for Bitcoin's outperformance are not primarily about speculation, they are about supply mechanics, adoption curve, and return profile of the underlying asset class.

This article gives you the complete comparison, including where the S&P 500 is clearly superior, and how to think about combining both. For Canadian-specific index fund options, see our Bitcoin ETF vs Direct Ownership guide. Compare this to our other comparison guides: Bitcoin vs Gold and Bitcoin vs Real Estate.

Why the S&P 500 Is the Default

Before comparing, it's worth being honest about why the S&P 500 is so widely recommended. It earns its reputation.

What the S&P 500 actually is

The S&P 500 is a market-cap-weighted index of the 500 largest US publicly traded companies. When you buy an S&P 500 index fund (VOO, SPY, XSP.TO for Canadians), you're buying a proportional ownership stake in Apple, Microsoft, NVIDIA, Amazon, and roughly 496 other companies, weighted by their market size.

These are real companies: Apple sells phones, Microsoft sells software, NVIDIA makes chips, Amazon delivers packages. They generate earnings, pay taxes, employ people, and produce goods and services that the world wants to buy. The S&P 500's long-run return is anchored to the fundamental productivity growth of the US economy and the world's most productive companies.

The index fund advantage

Index funds win against active managers because:

• Low cost: MER of 0.03-0.20% vs. actively managed funds at 0.5-2.0%
• Broad diversification: 500 companies across all sectors eliminates single-company risk
• No manager risk: No star manager to underperform after they leave
• Tax efficient: Low turnover generates fewer taxable events
• Systematic: No emotional decisions, no market timing

10-Year Returns: S&P 500 vs Bitcoin in CAD

Let's be precise about the numbers. We'll convert everything to CAD so Canadian investors can make a real comparison.

S&P 500 returns: S&P 500 total return index in USD, converted to CAD at Bank of Canada daily rates. Bitcoin: CoinGecko CAD-denominated data. All figures approximate.

The 10-year compounded return comparison: at 12.8% per year, the S&P 500 roughly tripled your money ($100K → $334K). At 63.8% per year, Bitcoin did approximately 4,200% ($100K → $4.2M). The difference is enormous.

The S&P 500 has never had a -64% year. Not once. The worst year in its history was -43% in 1931 during the Great Depression. The worst in recent history was -37% in 2008. Bitcoin has had multiple years with -50%+ drawdowns. This is the key tension in the comparison: Bitcoin is dramatically better on long-run return, but dramatically worse on short-term volatility. Which one is right for you depends on your time horizon, your emotional capacity, and your position sizing.

Risk-Adjusted Returns: Sharpe Ratio Comparison

Raw returns don't tell the full story. A better measure is the Sharpe ratio, return per unit of volatility risk. Higher is better.

Here's the insight that most people miss: the S&P 500 actually has a better Sharpe ratio than Bitcoin over this period, despite Bitcoin's dramatically higher returns. This is because Bitcoin's volatility is so extreme that it eats most of the return advantage when you price risk-adjusted performance.

A 60/40 portfolio of S&P 500 and bonds has historically had the best Sharpe ratio of these options, lower returns, but so much lower volatility that the return-per-risk is the highest. This is why the financial planning establishment recommends diversified index portfolios: they're not trying to maximize your return, they're trying to maximize your return per unit of risk you actually have to endure.

Volatility: What the Numbers Actually Mean

Bitcoin's volatility is real and it's substantial. But the way volatility is typically discussed in financial planning, as a proxy for risk, is somewhat misleading when applied to long holding periods.

The difference between volatility and risk

Volatility is a measure of short-term price fluctuation. Risk, as a portfolio concept, is the probability of permanent loss over your actual time horizon. A -82% drawdown in Bitcoin is devastating if you need to sell in 2022. It is irrelevant if you don't sell and the price recovers.

What happened in practice

Bitcoin's worst drawdowns in this period:

• 2014 drawdown: Bitcoin fell ~87% from $1,100 to ~$200 (peaked 2013, bottomed 2015). If you held through this, you saw the price recover to new highs in 2017.
• 2018 drawdown: Bitcoin fell ~80% from $20,000 to ~$3,200 in 2018-2019. If you held, you saw it recover to new highs in 2020-2021.
• 2022 drawdown: Bitcoin fell ~64% from ~$69,000 to ~$17,000. By late 2024, it had exceeded its prior all-time high. If you held, you were back to new highs in approximately 12 months from the bottom.

The S&P 500 has never had a year where it was down 50%+. It has had a decade where it returned 0% (the 2000-2010 dotcom bust recovery period). Bitcoin has had years with -80% returns and years with +1,000%+ returns. These are fundamentally different assets from a portfolio management perspective.

2022 stress year in numbers

The discipline that converts Bitcoin's volatility from an intolerable risk into a manageable one is position sizing. A 5% Bitcoin sleeve in a portfolio that draws down 22% in 2022 loses, in absolute terms, a little over 3% of total portfolio value to the Bitcoin position. That is uncomfortable but recoverable. A 50% Bitcoin sleeve in the same year would have lost 32%, survivable only with genuine temperament. A 100% Bitcoin sleeve would have lost 64%, the kind of drawdown that forces most retail investors to sell at the bottom.

Correlation

One of Bitcoin's most-cited diversification benefits is its historically low correlation with the S&P 500 during normal market conditions. The rolling 12-month correlation between Bitcoin and the S&P 500 over the past decade has typically sat in the 0.20 to 0.40 range, meaningfully below the 1.0 correlation among large-cap US equities themselves. In a steady-state Canadian portfolio, this means adding a 5-10% Bitcoin sleeve measurably reduces the volatility of the total portfolio per unit of expected return.

However, the correlation breaks down during acute risk-off windows. In March 2020 (the COVID crash), in mid-2022 (the synchronized equity-and-crypto drawdown), and in several shorter stress episodes, the rolling correlation spiked to 0.70-0.85, and both assets sold off together. The diversification benefit is real in steady-state markets but partially disappears in crashes, meaning the Bitcoin sleeve provides the most value during long, quiet compounding windows and provides the least protection during acute drawdowns.

For a Canadian investor, the practical implication is that Bitcoin behaves less like a high-beta technology stock and more like an emerging, partially uncorrelated asset class whose diversification value is genuine but conditional on not panicking during the synchronized drawdown windows when the correlation temporarily approaches 1.0.

Inflation hedge

The case for Bitcoin as an inflation hedge rests on its fixed supply, there will never be more than 21 million bitcoin, and on its non-sovereign, non-issuer-dependent nature. Unlike equities, which are claims on real-economy earnings affected by inflation through a complex chain of pricing power and cost pass-through, or bonds, which are claims on a fixed nominal coupon that inflation erodes directly, Bitcoin's supply schedule was set at its protocol level and cannot be altered by any central bank, government, or corporate issuer. Over a 15-year window, this has been the differentiation that matters most.

The honest reading: Bitcoin's inflation-hedging story is empirically supported over the past 15 years but rests on a small sample of macro regimes (low-rate, post-GFC liquidity expansion). A Canadian investor should size the Bitcoin allocation in proportion to their conviction that the next 15 years will feature a similar monetary regime, and that conviction cannot be assumed. The same caveat applies, with more confidence, to the S&P 500, its 15-year outperformance over cash was a function of declining rates and rising valuations, both of which may not repeat. For a focused gold-investor comparison, see our Bitcoin vs Gold guide.

The Canadian Dollar Factor

Canadian investors holding the S&P 500 face currency risk that US investors don't. This complicates the comparison.

CAD/USD exchange rate impact on S&P 500

When you buy an S&P 500 ETF (XSP.TO on the TSX, or VTI at Interactive Brokers in USD), your return in CAD depends on two things: the USD return of the index, and the CAD/USD exchange rate at time of conversion.

From 2016-2026, the Canadian dollar was volatile but roughly flat relative to the USD (ranging from approximately $0.71-$0.77 USD per CAD). This means the CAD return of the S&P 500 was approximately the same as the USD return, about 10.8% annually in USD vs 12.8% in CAD (the small difference comes from a period of CAD weakness in 2020-2021 that boosted CAD returns for USD assets).

Bitcoin and the CAD factor

Bitcoin is globally priced. When the CAD strengthens, Bitcoin in CAD terms costs more (same BTC, more CAD). When the CAD weakens, Bitcoin in CAD terms is cheaper. The net effect over a decade is small compared to Bitcoin's return, but it means Bitcoin's CAD return is partially determined by the same currency risk that affects the S&P 500.

For Canadian index investors who want USD exposure, the tax treatment of US-listed ETFs in RRSPs is more favorable than in TFSAs, holding VOO or VTI inside an RRSP avoids the 15% withholding tax on dividends that applies to US-listed ETFs held in TFSAs. See our CRA Tax Guide for the full breakdown.

Diversification: Index Funds vs Single Asset

This is where the S&P 500 wins categorically on paper: it holds 500 companies across every major sector of the US economy. Bitcoin holds one protocol.

What diversification actually does

The S&P 500's diversification means you're exposed to: Apple (consumer tech), Microsoft (enterprise software), NVIDIA (AI/chips), Amazon (e-commerce/cloud), JPMorgan (banking), Johnson & Johnson (pharma), and approximately 493 others. If any single company fails, it has limited impact on your portfolio. If an entire sector collapses (energy in 2014-2015, retail in 2015-2020, real estate in 2022-2023), other sectors hold up. The index is designed to absorb company and sector-specific failures.

Bitcoin's concentration

Bitcoin is a single asset with a single protocol. If Bitcoin's network fails, a fundamental security breach, a catastrophic bug, a government-enforced ban in major markets, your entire position could go to zero. This is a real risk, even if the probability is low. Bitcoin's 15-year survival record against regulatory attacks, exchange failures, security incidents, and market crashes has been strong, but history can never fully predict future outcomes.

The diversification argument for the S&P 500 is legitimate and important. It's one of the strongest reasons to hold it as a core portfolio anchor rather than replacing it entirely with Bitcoin. A 60% S&P 500 / 5% Bitcoin / 35% bonds portfolio gives you the upside optionality of Bitcoin with the diversification and stability of the US equity market. This is a portfolio structure that sophisticated Canadian investors are increasingly using.

Tax treatment for Canadians

Inside a TFSA, RRSP, or FHSA, both Bitcoin and the S&P 500 grow completely tax-free, and the gains, when withdrawn from a TFSA or RRSP, are not taxed at the personal level. Outside registered accounts, the two assets produce somewhat different tax streams that matter primarily for high-income investors with significant non-registered holdings.

• Capital property, 50% inclusion rate: Bitcoin held directly is treated as capital property for Canadian tax purposes. The 50% capital gains inclusion rate applies at the personal level, meaning only half of any realized gain is added to taxable income. Losses on Bitcoin can offset other capital gains.
• TFSA / RRSP / FHSA shelter: The most tax-efficient default for most Canadian investors is to hold both Bitcoin exposure (via a TSX-listed Bitcoin ETF) and S&P 500 exposure (via a TSX-listed S&P 500 ETF) inside a TFSA or RRSP, where the tax treatment of both is identical and tax-free. This is the dominant pattern recommended by Canadian financial advisors working with long-horizon retail investors.
• Dividend treatment gap: Outside registered accounts, S&P 500 index funds distributed by US-domiciled ETFs (VOO, SPY, IVV) do not generate Canadian-eligible dividends; Canadian-domiciled S&P 500 ETFs (XUS, VFV) do produce eligible dividend income that attracts the Canadian dividend tax credit. Bitcoin produces no dividend at all, the only return stream is capital appreciation on disposition.
• Foreign property reporting: A USD-denominated S&P 500 ETF (VOO, SPY) and a USD-denominated Bitcoin ETF held outside registered accounts both trigger T1135 foreign-property reporting if aggregated cost exceeds $100,000 CAD. The reporting obligation applies to investors with non-registered holdings; TFSA, RRSP, and FHSA holdings are exempt. Holding via Canadian-domiciled wrappers (TSX-listed ETFs) avoids this complication entirely.
• No preferential corporate-rate treatment: Both Bitcoin and S&P 500 holdings inside a Canadian-Controlled Private Corporation are taxed at the corporate rate, with the 50% capital gains inclusion still applying. The CCPC small-business deduction is unavailable on investment income; corporate holders should generally hold these assets personally (inside a TFSA or directly) rather than at the corporate level to avoid the higher passive-investment tax rate.

Accessibility: S&P 500 vs Bitcoin for Canadians

For a Canadian investor, accessibility to the two asset classes is operationally similar but not identical. The S&P 500 is available via US-domiciled ETFs (VOO, SPY, IVV) at any Canadian discount brokerage, via Canadian-domiciled TSX-listed ETFs (XUS, VFV, ZSP), and via mutual funds. Bitcoin is accessible via TSX-listed spot Bitcoin ETFs (FBTC, BTCC.B, EBIT, BTCX.B), via regulated Canadian crypto exchanges (Bitbuy, Bull Bitcoin, NDAX, Coinbase), via P2P cash trades, and via self-custody. The TSX-listed Bitcoin ETF structure, new in early 2021, collapses the accessibility gap for most retail investors.

The default for most Canadian retail investors is a TSX-listed Bitcoin ETF inside a TFSA or RRSP, this combination is the most tax-efficient, the most operationally simple, and the most defensible against the "I lost my seed phrase / seed phrase was stolen" failure mode that direct self-custody creates. Direct Bitcoin ownership via a regulated Canadian exchange with multi-sig self-custody is appropriate for larger positions or for investors with a specific operational reason for self-custody; a consulting advisor can help size the trade-off between operational simplicity and self-custody sovereignty.

Optimal Allocation: The Portfolio Approach

The research on combining Bitcoin and index funds has matured significantly by 2026. Here's what the evidence suggests.

The case for Bitcoin as a portfolio complement

Several academic papers and institutional research (Grayscale, Fidelity Digital Assets, NYDIG) have examined the portfolio impact of adding Bitcoin to a traditional 60/40 or 80/20 portfolio. The consistent finding: a small Bitcoin allocation (1-5% of total portfolio) improves risk-adjusted returns over a full market cycle, because Bitcoin's returns are sufficiently large that even a small position meaningfully impacts portfolio growth, while its volatility is somewhat offset by its low correlation to equities in certain periods.

How Canadian financial advisors are positioning this

As of 2024-2025, most Canadian financial advisors who work with Bitcoin at all recommend:

• Core portfolio: S&P 500 index (via XSP.TO at Questrade, or VOO/XSP at other brokerages) as the foundation
• Bitcoin allocation: 3-10% maximum, depending on risk tolerance and time horizon
• Account placement: Bitcoin ETFs inside a TFSA for tax-free growth alongside index funds
• Rebalancing: Annual rebalancing to maintain target allocation (the hardest part, selling a rising asset is psychologically difficult)

For corporate Bitcoin allocations (professional corporations, family businesses), the tax efficiency of holding Bitcoin inside the corporate account at the 12.2% corporate rate (Alberta) may be more advantageous than the TFSA, but this requires accounting advice specific to your situation. See our Corporate Bitcoin guide.

Three-tier sizing and rebalancing

For an investor who has decided to hold both the S&P 500 and Bitcoin, the question becomes how to size each. The defensible framework consists of three tiers, conservative, balanced, and aggressive, that match the allocation to the investor's temperament, time horizon, and tax structure. All three tiers assume the S&P 500 is the dominant holding for stability, dividends, and broad-market exposure; Bitcoin is the asymmetric-upside sleeve whose role is to participate in the long-term compounding return without breaking the portfolio during drawdowns.

• Conservative (1-5% Bitcoin): For investors with a 5-15 year time horizon, a moderate risk tolerance, and a primary need for portfolio stability. The 1-5% Bitcoin sleeve provides meaningful long-term participation while ensuring that a 50% Bitcoin drawdown depletes the portfolio by only 0.5-2.5% of total assets, recoverable from ordinary income in one or two years. The rebalancing rule: restore the target percentage whenever the position drifts more than 1.5x from target at any quarterly review.
• Balanced (5-10% Bitcoin): For investors with a 15-25 year time horizon, an above-average risk tolerance, and prior experience holding volatile assets through drawdowns. The 5-10% Bitcoin sleeve meaningfully shifts the portfolio's long-term compounding return profile while remaining small enough that a -64% yearly drawdown costs the portfolio 3.2-6.4%, painful but recoverable. The rebalancing rule: restore target whenever the position drifts more than 2x from target.
• Aggressive (10-20% Bitcoin): For investors with a multi-decade time horizon, high risk tolerance, and explicit acknowledgment that they will not panic-sell during synchronized drawdowns. Above 20%, the portfolio's volatility profile begins to dominate the investor's experience rather than the long-term average return, and most investors are not temperamentally suited for this tier regardless of stated conviction.

The rebalancing protocol is the active management step that makes either tier work: when the Bitcoin position rises above target at a quarterly review (e.g. a 5% target rises to 7%), sell the appreciation back to 5% and reallocate to the S&P 500 sleeve; when it falls below target (e.g. 5% falls to 3%), buy Bitcoin to restore the 5% target. This forces the investor to systematically sell strength and buy weakness, the exact pattern that maximizes long-term compounding in a volatile asymmetric asset.

Side-by-Side: The Full Comparison

What to Do With This Information

The conclusion most advisors reach by 2026: the question isn't "Bitcoin OR S&P 500", it's "what allocation to each makes sense for my time horizon, risk tolerance, and financial goals?"

• For long-term investors (10+ year horizon, high risk tolerance): A 5-10% Bitcoin allocation alongside a core S&P 500 position is the most defensible combined strategy. The Bitcoin allocation adds asymmetric upside with a manageable impact on total portfolio volatility if sized correctly.
• For conservative investors: Pure S&P 500 index (via XSP.TO or VOO) is the right foundation. Consider a small Bitcoin ETF position (2-3%) if you have high conviction, but understand the volatility is real and will test your conviction.
• For corporate balance sheets: Both S&P 500 ETFs and Bitcoin ETFs can be held in corporate investment accounts. The tax efficiency of Bitcoin at the corporate rate (12.2% Alberta) may make it more attractive relative to index funds if you have capital gains to defer. See our Corporate Bitcoin guide.
• For maximum tax efficiency: Hold both Bitcoin and S&P 500 ETFs inside a TFSA. Gains on both are completely tax-free. Rebalance with new contributions rather than selling, rebalancing inside a TFSA is more tax-efficient.

Frequently asked questions

Has Bitcoin outperformed the S&P 500 over the past decade in CAD terms?

Decisively. From 2016 to 2026, Bitcoin compounded at approximately 63.8% per year in CAD terms, while the S&P 500 returned approximately 14.2% per year in USD (approximately 12.8% per year in CAD due to Canadian dollar appreciation over the period). A $100,000 investment in the S&P 500 in January 2016 would be worth approximately $334,000 by January 2026 in CAD terms; a $100,000 position in Bitcoin would be worth approximately $4.2 million. The S&P 500 is a far more consistent, lower-volatility investment, the comparison requires understanding both sides of the trade-off.

How should a Canadian investor size a Bitcoin allocation alongside an S&P 500 position?

A defensible starting range is 1-5% of total portfolio for a conservative allocation, 5-10% for a balanced allocation, and 10-20% only for investors with multi-decade horizons and the temperament to hold through a 50%+ drawdown without selling. The rebalancing rule is to restore the target percentage whenever the position drifts more than 2x from target, i.e. if a 5% Bitcoin allocation rises to 12%, trim back to 5%; if it falls to 2%, top up. This forces the investor to systematically sell strength and buy weakness, which is the long-term compounding engine for both asset classes.

What was Bitcoin's worst year versus the S&P 500, and why does it matter for sizing?

Bitcoin's worst calendar year in this window was 2022, when it fell approximately -64% in CAD terms during the same period that the S&P 500 fell approximately -19% in USD (approximately -21% in CAD). Both assets fell; Bitcoin fell meaningfully more. In a 50/50 joint allocation, the portfolio would have declined roughly 42% in 2022, survivable but visible. In a 95% S&P 500 / 5% Bitcoin portfolio in that year, total portfolio drawdown was approximately 22%, materially better. Position sizing is the discipline that converts Bitcoin's volatility from an intolerable risk into an acceptable one.

How does Canadian tax treatment differ between S&P 500 index funds and Bitcoin?

Inside a TFSA or RRSP, both assets grow completely tax-free, and contributions, ETF structure, and capital gains inside those wrappers are tax-shielded identically for the individual investor. Outside registered accounts, the S&P 500 produces two distinct tax streams: capital gains (taxed at the 50% inclusion rate at the marginal rate) and dividends (taxed at a lower rate due to the Canadian dividend tax credit). Bitcoin produces only capital gains when realized, no dividend, no interest, no distribution. For most individual Canadians, holding both inside a TFSA is the most efficient default, and the tax treatment difference between the two assets is zero in that case.

What is the correlation between Bitcoin and the S&P 500?

The rolling 12-month correlation between Bitcoin and the S&P 500 has historically been low, typically in the 0.20 to 0.40 range during normal market conditions, but spikes toward 0.70 to 0.85 during acute risk-off periods when both assets sell off together. The diversification benefit is real in steady-state portfolios but partially breaks down during crashes, when both assets can decline simultaneously. For a Canadian investor, this means Bitcoin behaves less like a development-stage technology stock and more like an emerging uncorrelated asset class whose diversification value is genuine but conditional on not panicking during the synchronized drawdown windows.
