In investing and trading, many people focus first on returns. For example, if one strategy gains 20% in a month while another gains 8%, the first one may look clearly better. But if the first strategy suffers a maximum drawdown of 40%, while the second has a maximum drawdown of only 3%, would you still think the first one is necessarily superior?

This is exactly the question Risk Adjusted Return, or RAR, is designed to answer.

The core idea of RAR is simple: returns should not be discussed separately from risk. What really matters is not only how much a strategy earns, but how much risk it takes to earn that return. This is especially important in the crypto market, where volatility is high and short-term high returns may hide large drawdowns, excessive leverage, and liquidation risk.

What Is RAR?

Risk Adjusted Return is not one single fixed formula. Instead, it refers to a group of methods used to evaluate the real performance of an asset, portfolio, or trading strategy after considering risk.

In simple terms:

Ordinary return only asks: “How much did it make?”
RAR asks: “How much risk was taken to make it?”
The higher the RAR, the better the return generated per unit of risk

For example, Strategy A has an annualized return of 30% with a maximum drawdown of 25%. Strategy B has an annualized return of 18% with a maximum drawdown of 5%. If we only look at returns, Strategy A looks more attractive. But after considering risk, Strategy B may be more stable and more suitable for long-term execution.

This is why professional investors do not only look at whether an equity curve is moving upward. They also pay attention to volatility, drawdown, Sharpe Ratio, Sortino Ratio, Calmar Ratio, and other risk-adjusted metrics.

RAR Important in Crypto Trading

One of the biggest features of the crypto market is high volatility. Sharp rises and falls can happen within a short period. Many strategies look impressive during a bull market, but once the market reverses, their drawdowns can become severe.

For crypto traders, RAR is useful in several ways:

It helps avoid being misled by short-term high returns
It helps evaluate whether a strategy is sustainable over the long run
It allows traders to compare the real performance of different assets, strategies, or traders
It helps improve leverage and position management
It helps identify portfolios with high returns but uncontrolled risk

For example, two traders both make 15% in one month. The first trader uses low leverage and has a maximum drawdown of 4%. The second trader uses high leverage and suffers a maximum drawdown of 35%. Their returns look the same, but from a risk-adjusted perspective, the first trader’s performance is much healthier.

Common Ways to Measure RAR

RAR can be measured through different indicators. Beginners do not need to master every complex formula at once, but they should understand what each metric focuses on.

Sharpe Ratio: How Much Excess Return Is Earned per Unit of Volatility?

The Sharpe Ratio is one of the most commonly used risk-adjusted return indicators. It compares the return above the risk-free rate with the overall volatility of the investment.

A simplified formula is:Sharpe Ratio = Excess Return / Volatility

The higher the Sharpe Ratio, the more return is generated under the same level of volatility. For a trading strategy, a higher Sharpe Ratio often means a smoother return curve and better risk control.

However, the Sharpe Ratio treats both upside and downside volatility as risk. In reality, many traders are more concerned about downside volatility, or losses.

Sortino Ratio: More Focused on Downside Risk

The Sortino Ratio is similar to the Sharpe Ratio, but it only focuses on downside volatility. In other words, it pays attention to volatility that leads to losses.

A simplified formula is:Sortino Ratio = Excess Return / Downside Volatility

This is very practical for crypto trading. Many crypto assets may have large upside moves, but what traders truly worry about is sharp declines and account drawdowns. Compared with the Sharpe Ratio, the Sortino Ratio is closer to the question: “How much loss risk did I take?”

Calmar Ratio: The Relationship Between Return and Maximum Drawdown

The Calmar Ratio is often used to evaluate the stability of a strategy, especially for trend-following strategies, quantitative strategies, and long-term portfolios.

A simplified formula is:Calmar Ratio = Annualized Return / Maximum Drawdown

If a strategy has an annualized return of 40% and a maximum drawdown of 20%, its Calmar Ratio is 2. If another strategy has an annualized return of 25% and a maximum drawdown of 5%, its Calmar Ratio is 5. Although the second strategy has a lower return, its risk control is much stronger.

For ordinary traders, the Calmar Ratio is very intuitive because maximum drawdown often determines whether you can continue executing a strategy.

Practical Example: How to Use RAR to Compare Two Strategies

Suppose you are comparing two crypto trading strategies.

Strategy A:

Monthly return: 20%
Maximum drawdown: 30%
Return curve: highly volatile
Trading style: high-leverage short-term trading

Strategy B:

Monthly return: 8%
Maximum drawdown: 4%
Return curve: relatively stable
Trading style: low-leverage trend following

If you only look at return, Strategy A looks more attractive. But from the perspective of RAR, Strategy B may be better. It uses much smaller drawdowns to generate relatively stable returns, making it easier for traders to follow over the long term.

You can evaluate strategies through the following steps:

Step 1: Record the return of each strategy over the same period

Step 2: Measure the maximum drawdown during that period

Step 3: Observe whether the return curve is smooth

Step 4: Check whether the profits mainly come from a few high-risk trades

Step 5: Ask whether you can personally tolerate the maximum loss

A simple beginner-friendly method is:Return / Maximum Drawdown

The higher this ratio, the better the return generated under the same drawdown. Although this is not a complete professional model, it is useful for quickly judging the quality of a strategy.

How RAR Helps with Position Management

RAR is not only useful for comparing strategies. It can also help improve your own trading behavior.

Many traders lose money not because their market direction is always wrong, but because their position size is too large or their leverage is too high. A single market fluctuation may then cause an unacceptable drawdown. RAR reminds us that improving returns does not always mean taking more risk. Sometimes, reducing volatility and drawdown can improve overall performance.

In practice, traders can:

Limit the risk of each trade to a fixed percentage of account equity
Avoid blindly adding positions after consecutive losses
Avoid putting all capital into one asset or one market direction
Review both return and drawdown regularly, instead of only checking profit
Reduce position size for high-volatility assets and adjust exposure more carefully

For example, if a strategy has good returns but frequently experiences drawdowns above 25%, you do not necessarily need to abandon it. You may improve its RAR by lowering leverage, reducing position size, and adding clearer stop-loss rules.

Common Mistakes Beginners Should Avoid

Mistake 1: Thinking higher return always means a better strategy

High return with extremely high risk may not be suitable for long-term trading.

Mistake 2: Treating drawdown as temporary and unimportant

Drawdown determines whether your account can survive and whether you can keep following the strategy.

Mistake 3: Only looking at one month of performance

RAR should be observed over a sufficiently long period. Short-term data may be random.

Mistake 4: Ignoring the impact of leverage

Leverage magnifies both gains and losses, so it must be included in risk evaluation.

Mistake 5: Comparing different timeframes directly

Intraday, swing, and long-term strategies have different risk profiles. Comparisons should use the same period and consistent standards whenever possible.

Conclusion: RAR Helps You Move from “Fast Profit” to “Stable Profit”

The core purpose of Risk Adjusted Return is not to make you give up returns, but to help you understand the cost behind those returns. A truly strong strategy should not only make money in favorable markets, but also control drawdowns in sideways or adverse markets.

For crypto traders, RAR is an important tool for building long-term trading thinking. It reminds us not only to ask, “How much can this strategy make?” but also, “How much could it lose?” “Can I tolerate this level of volatility?” and “Is the return worth the risk?”
