Risk-Adjusted Returns: Comparing Stocks and Crypto Performance

Crypto's raw returns look spectacular. Bitcoin has appreciated more than 10,000% over the past decade. Ethereum has done even better in percentage terms. No traditional asset class comes close to these headline numbers. But raw returns tell a dangerously incomplete story that leads traders to take risks they do not fully understand.

Risk adjusted returns strip away the illusion created by headline performance and reveal what you actually earned per unit of risk taken. When you compare stocks and crypto on this basis, the gap narrows dramatically. Understanding why, and what it means for portfolio construction, is one of the most important analytical skills a multi asset trader can develop.

Why Raw Returns Are Misleading

Raw returns ignore the volatility required to capture them. A 100% return looks identical whether it came from a steady climb or a rollercoaster that included a 60% drawdown along the way. But the experience of holding through a 60% drawdown is radically different from riding a smooth uptrend, and the behavioral risk of selling at the bottom is much higher in the volatile scenario.

Raw returns also ignore the timing problem. The average annual return of an asset class is experienced by almost no one because most investors do not buy at the beginning and hold until the end. They buy and sell along the way, often at the worst possible times because volatility triggers emotional decisions.

This is why risk adjusted metrics exist. They account for the cost of volatility and provide a more honest comparison of what different assets actually deliver to real world traders and investors.

Understanding Risk Adjusted Return Metrics

The most commonly used risk adjusted metrics each capture a different aspect of the risk and return tradeoff. The Sharpe ratio measures excess return per unit of total volatility. The Sortino ratio measures excess return per unit of downside volatility only. The Calmar ratio measures annualized return relative to maximum drawdown. Each metric answers a slightly different question about how efficiently an asset converts risk into return.

No single metric tells the complete story. A high Sharpe ratio might mask a terrible maximum drawdown if the drawdown was brief. A good Calmar ratio might hide periods of extreme volatility that made the asset difficult to hold. The most informative analysis uses multiple metrics together to build a comprehensive picture.

Sharpe Ratio Comparison Stocks vs Crypto

The Sharpe ratio is calculated as the annualized return minus the risk free rate, divided by the annualized standard deviation of returns. A Sharpe ratio above 1.0 is considered good. Above 2.0 is excellent. Below 0.5 suggests the return is not adequately compensating for the risk.

Over the past decade, the S&P 500 has delivered a Sharpe ratio of approximately 0.7 to 1.0, depending on the exact time period. This is consistent with historical averages and reflects the relatively stable risk and return profile of broad equity markets.

Bitcoin's Sharpe ratio over the same period varies dramatically depending on the measurement window. Over the full decade, it ranges from 0.8 to 1.2, which is surprisingly similar to stocks when measured over long periods. However, when measured over shorter periods like one to three years, Bitcoin's Sharpe ratio swings wildly between negative territory during bear markets and above 2.0 during bull runs.

The key insight is that over sufficiently long horizons, Bitcoin's risk adjusted returns converge toward those of stocks. The spectacular raw returns are largely offset by the spectacular volatility.

Sortino Ratio and Downside Risk

The Sortino ratio improves on the Sharpe ratio by penalizing only downside volatility rather than total volatility. This distinction matters because upside volatility is desirable. No investor complains about unexpectedly large gains. The risk that matters is the risk of losing money.

Stocks typically show a Sortino ratio between 1.0 and 1.5 over multi year periods. Bitcoin's Sortino ratio is often slightly higher than its Sharpe ratio because its upside volatility (explosive rallies) is typically more extreme than its downside volatility (severe but somewhat bounded drawdowns).

For traders who are comfortable with upside volatility but want to minimize downside risk, the Sortino ratio provides a more relevant comparison. By this metric, Bitcoin looks slightly more attractive relative to stocks than the Sharpe ratio suggests, because its upside volatility contribution is removed from the denominator.

Maximum Drawdown Analysis

Maximum drawdown measures the largest peak to trough decline in an asset's price. This metric captures the worst case experience an investor would have endured and is arguably the most practically important risk metric because it determines whether you can psychologically survive holding the position.

The S&P 500's maximum drawdown over the past decade was approximately 34% during March 2020. It recovered to new highs within roughly five months. Over the past 25 years, the worst drawdown was approximately 57% during the 2008 financial crisis, with a recovery that took about four years.

Bitcoin's maximum drawdown history is considerably worse. The asset has experienced multiple drawdowns exceeding 50%, with the 2022 decline from roughly $69,000 to roughly $16,000 representing a 76% drawdown. Previous cycles saw similar or even larger percentage declines.

The practical implication is stark. A 76% drawdown means that to break even, the asset needs to rally approximately 315%. While Bitcoin has historically achieved those recoveries, the time spent underwater and the psychological toll of watching your investment lose three quarters of its value is something that most investors severely underestimate.

Calmar Ratio for Long Term Comparison

The Calmar ratio divides annualized return by maximum drawdown, providing a measure of how much return you receive relative to the worst pain you endure. A higher Calmar ratio means better return per unit of worst case risk.

The S&P 500's Calmar ratio over the past decade is approximately 0.3 to 0.5 (10% to 15% annualized return divided by 34% maximum drawdown). Bitcoin's Calmar ratio varies enormously by time period but tends to cluster around 0.3 to 0.6 when measured over full market cycles.

The convergence in Calmar ratios between stocks and crypto reinforces the finding that risk adjusted returns are much closer than raw returns suggest. Bitcoin delivers higher absolute returns but at the cost of much deeper drawdowns, resulting in similar efficiency when measured per unit of maximum risk.

Rolling Performance Windows

Analyzing risk adjusted returns over rolling windows rather than fixed start and end dates provides a more robust comparison. A 3 year rolling Sharpe ratio shows how consistently each asset delivers risk adjusted returns across different market regimes.

The S&P 500's 3 year rolling Sharpe ratio is remarkably stable, typically staying between 0.3 and 1.5. This consistency is one of stocks' greatest strengths. You can expect a reasonably predictable risk adjusted return profile over medium term horizons.

Bitcoin's 3 year rolling Sharpe ratio varies from below negative 1.0 during bear markets to above 3.0 during bull markets. This extreme variation means that the time period during which you are invested in Bitcoin has an outsized impact on your experience. The long term average may be similar to stocks, but the journey is far more turbulent.

How Volatility Affects Real World Returns

Volatility drag is a mathematical reality that reduces compound returns below what simple arithmetic averages suggest. If an asset goes up 50% one year and down 50% the next, the arithmetic average return is 0%. But the actual compound return is negative 25% because you ended up with $0.75 for every dollar invested.

This effect is much more pronounced in crypto than in stocks because of the higher volatility. Bitcoin's arithmetic average annual return is significantly higher than its compound annual growth rate precisely because of this drag. The gap between the two represents the hidden cost of volatility that raw return figures do not capture.

Understanding this effect is crucial for portfolio construction. It means that the optimal allocation to a high volatility asset like crypto is lower than raw return comparisons would suggest, because the volatility drag consumes a larger share of the theoretical return.

Building a Risk Adjusted Portfolio

The most practical application of risk adjusted return analysis is portfolio construction. Rather than maximizing raw returns, the goal should be maximizing risk adjusted returns for your specific risk tolerance.

A portfolio that allocates 80% to broad equity indices and 20% to Bitcoin has historically produced better risk adjusted returns than either asset alone, because the diversification benefit partially offsets the higher volatility of the crypto allocation. The optimal crypto allocation, from a pure Sharpe ratio perspective, is typically between 5% and 20% depending on the measurement period and correlation assumptions.

The key constraint is maximum drawdown. Even if a higher crypto allocation improves the Sharpe ratio, it may produce a maximum drawdown that exceeds your tolerance. Finding the allocation that maximizes risk adjusted returns subject to your drawdown constraint is the practical optimization problem every multi asset trader faces.

How WalletFinder.ai Helps Evaluate Risk Adjusted Performance

WalletFinder.ai provides the cross market data infrastructure needed to evaluate risk adjusted performance across stocks and crypto. The stock screening tools track equity market returns and volatility metrics, while the crypto wallet tracker monitors the performance of on chain participants whose strategies you might want to replicate. The AI signals help identify when the risk adjusted opportunity in one market is more attractive than the other, supporting dynamic allocation decisions.

Practical Takeaways for Portfolio Construction

Do not chase raw returns. Focus on the Sharpe and Sortino ratios of your overall portfolio rather than the raw performance of individual positions. Size your crypto allocation based on the maximum drawdown you can survive, not the maximum return you hope to capture. Use rolling performance windows to assess whether your strategy is delivering consistent risk adjusted returns or relying on a single favorable period. And rebalance systematically to maintain your target risk profile as market conditions change.

FAQs

Does crypto have better risk-adjusted returns than stocks?

Over long time horizons of five years or more, crypto's risk adjusted returns as measured by the Sharpe ratio converge toward those of stocks. Bitcoin's higher raw returns are largely offset by its dramatically higher volatility. Over shorter periods, the comparison varies wildly depending on whether you measure during a bull or bear cycle. The practical takeaway is that combining both assets in a portfolio often produces better risk adjusted returns than either asset alone.

What is a good Sharpe ratio for a crypto portfolio?

A Sharpe ratio above 1.0 is generally considered good for a crypto portfolio, given the asset class's inherent volatility. Achieving this consistently requires active risk management, position sizing discipline, and ideally a multi asset approach that includes stocks alongside crypto. Pure crypto portfolios tend to have highly variable Sharpe ratios, swinging between negative territory in bear markets and above 2.0 in bull markets.

How do I calculate risk-adjusted returns for my portfolio?

Calculate the Sharpe ratio by subtracting the risk free rate (current Treasury bill yield) from your portfolio's annualized return and dividing by the annualized standard deviation of your returns. For the Sortino ratio, use only downside deviation in the denominator. For the Calmar ratio, divide your annualized return by your maximum drawdown. WalletFinder.ai provides the cross market performance data needed to evaluate these metrics across both your stock and crypto positions.
