What Is Risk Adjusted Return for Smart Investing

2025-09-30

At its core, the risk adjusted return is a way of measuring how much profit you made compared to the amount of risk you took on to get it. It’s a simple but powerful idea that shifts the focus from the raw return percentage to the quality and efficiency of that return.

Moving Beyond Returns to Find True Value

It’s natural for investors to chase the highest numbers. A portfolio that gains 15% in a year feels leagues better than one that only managed 10%. But is it really? This surface-level thinking misses half the story: the journey you took to get that return.

Think of it like choosing between two jobs. Job A pays $150,000 a year but demands grueling 80-hour weeks with sky-high stress. Job B pays $100,000 but offers a steady 40-hour week and a great work-life balance. Which job is “better”? The higher salary is tempting, but it comes with a severe risk of burnout. The second job provides a lower “return” (salary) but with far less “risk” (stress and exhaustion).

This is the exact trade-off that risk adjusted return helps you evaluate in your portfolio. That exciting 15% gain might have been the result of a wild ride on a volatile asset that could have just as easily crashed by 20%. On the other hand, the steady 10% return might have come from a stable, low-risk investment that let you sleep soundly at night.

The True Purpose of This Metric

The whole point is to level the playing field. It creates a framework for a more apples-to-apples comparison between completely different assets-say, a high-flying tech stock and a conservative utility stock. By factoring in the volatility and bumps along the road, you can see which investment actually did a better job of rewarding you for the risk you took on.

Answering “what is risk adjusted return” is about shifting your mindset from “How much did I make?” to “How much did I make for every unit of risk I endured?” This powerful perspective is fundamental to building a resilient and truly successful long-term portfolio.

Ultimately, this metric helps you answer a few critical questions about your investments:

Was the risk worth the reward? It puts a number on whether your gains actually justified the potential for losses.
Which investment is more efficient? It shines a light on assets that generate strong returns without all the gut-wrenching volatility.
Does this align with my goals? It helps you make sure your portfolio’s risk profile actually matches your personal comfort level.

Understanding the Building Blocks of Investment Analysis

To really get what risk-adjusted return is all about, we first have to pull apart its two core pieces: risk and return. Looking at one without the other is a classic rookie mistake. It’s like trying to drive a car by only staring at the speedometer-you might be going fast, but you have no clue if you’re headed for a ditch.

In the investing world, risk is so much more than just the chance of losing your money. It’s the wild, unpredictable nature of an asset’s journey. An investment that skyrockets with a +20% gain one month only to plunge -15% the next is a high-risk gamble, even if the “average” return looks decent on paper. This roller-coaster ride is what keeps investors up at night.

Defining Investment Risk and Return

The go-to metric for measuring this volatility is something called standard deviation. A high standard deviation means an investment’s returns are all over the map, signaling dramatic price swings. A low standard deviation, on the other hand, tells you that returns are much more stable and predictable. If you want to dive deeper into this, our comprehensive guide on estimating investment risk is a great place to start.

Then there’s the other side of the coin: return. This one’s simple enough-it’s the total gain or loss you make on your investment, usually shown as a percentage. It’s the flashy number everyone loves to brag about, but it’s only half the story if you don’t know the risks you took to get there.

Risk: The degree of uncertainty or volatility in an investment’s returns. Higher risk implies a wider range of potential outcomes, both good and bad.

Return: The total profit or loss on an investment, shown as a percentage of the initial cost.

Establishing the Performance Baseline

There’s one last piece to this puzzle: the risk-free rate of return. This is the theoretical return you could get from an investment with zero risk. Of course, no investment is truly 100% safe, but the yield on short-term government debt, like U.S. Treasury bills, is the closest we can get and is used as the standard benchmark.

Think of the risk-free rate as your baseline-the absolute minimum you should demand for taking on any risk. If a volatile stock is only expected to earn 3%, and a government bond is also offering 3%, why on earth would you choose the stock? The risk-free rate gives us a starting point to figure out the excess return-the extra reward you get for being brave enough to face the market’s ups and downs. This idea is the foundation for calculating risk-adjusted returns.

Calculating Your Investment’s Performance with the Sharpe Ratio

Alright, we’ve got a handle on risk and return. Now, let’s put them together with the most popular tool in the shed for this job: the Sharpe Ratio.

Developed by Nobel laureate William F. Sharpe, this metric is brilliant in its simplicity. It tells you exactly how much extra return you’re getting for every bit of risk you decide to take on.

The formula might look a little intense at first glance, but it’s actually quite simple. It just takes the return you made above a “risk-free” investment and divides it by the investment’s choppiness (its standard deviation).

Sharpe Ratio = (Portfolio Return − Risk-Free Rate) / Standard Deviation

This one number gives you a powerful way to compare totally different investments on a level playing field. It answers the fundamental question: “Was the return I got worth the rollercoaster ride?”

Breaking Down the Calculation Step-by-Step

Let’s walk through this with a real-world example. Imagine you’re looking at a popular tech ETF with the following numbers from the past year:

Annual Return: 12%
Standard Deviation (Volatility): 18%
Risk-Free Rate (like a T-bill): 3%

To see how this works in practice, let’s create a quick table breaking down the calculation for our tech ETF.

Sharpe Ratio Calculation Example

Component	Description	Example Value
Portfolio Return (Rp)	The ETF’s total return over the period.	12%
Risk-Free Rate (Rf)	The return on a “no-risk” asset like a T-bill.	3%
Excess Return	The return earned above the risk-free rate.	9% (12% – 3%)
Standard Deviation (σp)	The measure of the ETF’s price volatility.	18%
Sharpe Ratio	The final calculated risk-adjusted return.	0.5 (9% / 18%)

So, after plugging in the numbers, our tech ETF has a Sharpe Ratio of 0.5. This means you earned half a unit of return for every unit of risk you weathered. Not bad, but let’s see what that really tells us.

How to Interpret the Sharpe Ratio

So, what does a 0.5 actually mean? Think of the Sharpe Ratio as an efficiency score. The higher the number, the better the investment was at making money relative to the amount of drama (risk) it created along the way.

Here’s a general framework for what the numbers mean:

Below 1.0: The returns aren’t great for the amount of risk you took on.
1.0 to 1.99: This is considered good. The investment delivered solid returns for its volatility.
2.0 to 2.99: Now we’re talking. This is a sign of very good risk-adjusted performance.
Above 3.0: Exceptional. These are the kinds of numbers that get managers noticed.

This framework is most powerful when you’re comparing options. Let’s say you were looking at another fund that only returned 10% but had a much lower standard deviation of just 7%. Its Sharpe Ratio would be 1.0 ((10% - 3%) / 7%).

Even though its raw return was lower, the second fund was twice as efficient at turning risk into profit. That’s a huge insight.

This concept even applies to the market as a whole. Since 1928, the S&P 500 has delivered an average annual return of about 10%, with volatility around 15%. Using a historical risk-free rate of roughly 3%, its long-term Sharpe ratio works out to about 0.47. This tells us that, on average, investors earned just under half a unit of return for every unit of risk they took on by being in the market. You can dive into the historical data on S&P 500 returns to see these trends for yourself.

Focusing on What Matters with the Sortino Ratio

The Sharpe Ratio is a fantastic, workhorse tool for investors, but it has one big quirk: it treats all volatility as bad. This means a sudden, massive price jump-the kind of thing we all dream about-gets penalized as “risky” in the exact same way a catastrophic drop does. For most of us, that upside swing isn’t risk; it’s the whole point.

This is where a more nuanced metric, the Sortino Ratio, comes into play. It offers a crucial upgrade by zeroing in on the volatility that actually costs you money.

Think of it this way: the Sharpe Ratio is like a weather app that alerts you to any change from a perfectly calm, sunny day. The Sortino Ratio is smarter; it only buzzes your phone when a real storm is brewing-the kind of “bad” weather you actually need to worry about. It intelligently ignores the pleasant surprises.

Distinguishing Good Volatility from Bad

The Sortino Ratio fine-tunes the risk-adjusted return calculation by measuring only downside deviation. Instead of using total volatility (standard deviation) like the Sharpe Ratio, it only looks at the times an asset’s return dips below a specific target, which is often the risk-free rate.

This distinction is a game-changer for investors focused on protecting their capital and steering clear of major losses. It answers a much more practical question: “How much return did I get for every unit of harmful risk I took on?”

By isolating downside risk, the Sortino Ratio provides a clearer picture of an investment’s performance during stressful periods. It helps identify assets that protect capital better when markets get rough, which is a key goal for many long-term investors.

For instance, a high-growth tech stock might have a lower Sharpe Ratio because of its massive upward swings. But if it rarely suffers big drops, its Sortino Ratio could be much higher, revealing its true strength in managing the risk that matters.

The infographic below gives a clean, side-by-side look at how the Sharpe and Sortino Ratios approach risk and performance.

As you can see, the core difference is how “risk” is defined. The Sharpe Ratio sees all variance as risk, while the Sortino Ratio focuses squarely on performance below a set target.

To make the comparison even clearer, let’s break down their key differences.

Sharpe Ratio vs. Sortino Ratio Key Differences

Feature	Sharpe Ratio	Sortino Ratio
Primary Focus	Measures return per unit of total risk	Measures return per unit of downside risk
Risk Measurement	Uses standard deviation (all volatility)	Uses downside deviation (only “bad” volatility)
Best For	General-purpose risk assessment for traditional portfolios	Evaluating investments with asymmetrical returns (e.g., hedge funds, growth stocks) or for conservative, capital-preservation strategies

This table neatly sums up why choosing the right tool for the job is so important.

When to Use the Sortino Ratio

So, when should you reach for this specialized tool? The Sortino Ratio really shines in a few specific situations:

Evaluating Asymmetrical Investments: It’s perfect for assets like hedge funds or certain high-growth stocks whose returns feature long periods of steady gains punctuated by either sharp rises or falls.
For Conservative Investors: If your main goal is capital preservation, the Sortino Ratio gives a more accurate read on an investment’s ability to shield you from significant losses.
Comparing Volatile Assets: When you’re looking at two investments with similar Sharpe Ratios but very different volatility patterns, the Sortino Ratio can be the tiebreaker, revealing which one is better at managing downside risk.

Ultimately, using both ratios gives you a much richer, more complete picture of an investment’s risk-adjusted performance. It’s about layering insights to make smarter, more confident decisions with your money.

How Professionals Use Risk Adjusted Metrics

Knowing the theory behind risk-adjusted returns is one thing, but seeing it in the wild is where it really clicks. For financial pros, these metrics aren’t just abstract concepts from a textbook. They are the essential tools of the trade, driving smart decisions every single day.

Portfolio managers, for instance, live and breathe these numbers. Their entire job revolves around building portfolios that not only chase high returns but also align with a client’s specific comfort level for risk.

Using the Sharpe and Sortino ratios, they can compare different funds, stocks, and other assets on an apples-to-apples basis. This ensures every new addition to a portfolio is actually pulling its weight and delivering a worthwhile reward for the volatility it brings. The goal is always to build a balanced, efficient collection of assets. For a closer look at how this works, check out our guide on rebalancing your investment portfolio.

Beyond Portfolio Management

This way of thinking goes far beyond just managing a personal investment account. Big financial institutions like banks and insurance companies depend on a similar, high-stakes framework called Risk-Adjusted Return on Capital (RAROC).

RAROC is how these giants decide if a particular loan, a new business division, or a major investment is a good use of their capital once all the potential risks are tallied up. It boils down to the same fundamental question we ask as investors: “Is the potential reward here worth the risk I have to take?”

A bank might use RAROC to evaluate a new type of small business loan. The interest rate might look attractive on the surface, but if the default risk is too high, the RAROC will be low. That’s a clear signal that it’s a poor use of the bank’s capital.

This framework has been a cornerstone for measuring profitability for decades. Research on banking products, for example, has shown how tracking monthly RAROC can reveal whether a specific service is creating or destroying value for the institution. It’s a powerful tool that helps managers spot winning products and fix the ones that are lagging.

How You Can Use This as an Individual Investor

You don’t need to be a Wall Street quant to put this powerful mindset to work. The same logic can help you make much smarter decisions with your own money.

Here are a few practical ways to start thinking like a pro:

Compare ETFs and Mutual Funds: Don’t just get dazzled by a fund’s advertised one-year return. Dig a little deeper and compare the Sharpe or Sortino ratios to see which fund was more efficient at generating its profits.
Grade Your Own Strategy: Are you taking on a ton of risk just for mediocre returns? A quick risk-adjusted calculation can be a real eye-opener, showing you if your current approach needs a serious tune-up.
Steer Clear of the Hype: That hot stock with explosive gains almost always comes with terrifying downside volatility. A risk-adjusted view helps you see past the noise and recognize when a steadier, less sensational investment is actually the better long-term choice.

Common Pitfalls and What to Watch Out For

While risk adjusted return metrics are powerful tools, they are certainly not a crystal ball. A major pitfall is putting too much faith in historical data. Past performance, no matter how stellar, never guarantees what will happen next. A sky-high Sharpe Ratio from last year doesn’t make an asset immune to a market crash tomorrow.

It’s also crucial to remember that these ratios don’t see the whole risk picture. Standard deviation is great for measuring price swings, but it’s blind to other, equally critical dangers that can sneak up on you.

Liquidity Risk: The danger that you can’t sell an asset quickly without taking a major haircut on the price.
Geopolitical Risk: The threat of sudden, unpredictable events like international conflicts sending shockwaves through the markets.
Systemic Risk: The scary possibility of a market-wide collapse that drags down nearly all assets with it.

Misinterpreting the Numbers

Another common mistake is just assuming a bigger number is always better, no matter the context. Comparing the Sharpe Ratio of a volatile tech stock to that of a stable utility bond is a classic apples-to-oranges mistake. These metrics are most useful when you’re comparing similar types of investments.

A risk adjusted return figure is a valuable piece of the puzzle, not the whole picture. It should be one of many tools used in a comprehensive analysis.

At the end of the day, think of these tools as guides, not gospel. They offer a much smarter way to look at performance, but a holistic approach is still non-negotiable. This is why understanding how to diversify an investment portfolio remains a cornerstone strategy for managing the kinds of risks that a single number can never fully capture.

Common Questions About Risk Adjusted Return

Diving into investment metrics always stirs up a few questions. Let’s walk through some of the most common ones to make sure the concept of risk adjusted return is crystal clear.

What Is a Good Risk Adjusted Return?

There’s no magic number that works for everything, as “good” always depends on the context. You wouldn’t expect a government bond and a high-growth tech stock to have the same risk profile, right?

That said, a useful rule of thumb for the Sharpe Ratio is that a value above 1.0 is considered good. This tells you an investment is punching above its weight, generating excess returns that are greater than the total risk it’s taking on.

1.0 to 1.99: A solid, efficient performance. The return is justifying the risk.
2.0 or higher: This is excellent. It signals an investment that’s delivering outstanding returns for the level of risk involved.

If a ratio is below 1.0, it’s a sign that the returns might not be worth the headache of the risk you endured. The key is to always compare apples to apples-a tech fund’s Sharpe Ratio should be measured against other tech funds, not a basket of corporate bonds.

Can a Risk Adjusted Return Be Negative?

Absolutely, and it’s a major red flag when it happens. A negative risk adjusted return simply means the investment failed to even beat the return of the safest possible asset.

For instance, if a fund you were in gained 2% for the year, but the risk-free rate (like a short-term Treasury bill) was 3%, the first part of your Sharpe Ratio calculation (2% - 3%) would be negative.

A negative Sharpe or Sortino ratio is a clear signal of poor performance. It means you took on all the risks of the market for a return that was worse than if you had just stuck your money in the safest investment available.

In this scenario, the investment didn’t just underperform; it failed to clear the lowest possible bar. It was an inefficient use of your capital for that time frame.

Why Not Just Focus on the Highest Absolute Return?

It’s tempting, isn’t it? Chasing the highest number is a common but dangerous trap for investors. An investment might boast a massive 30% gain, but what if getting there involved wild, gut-wrenching swings and a few near-death experiences for your portfolio? Was that truly a “good” investment? That shiny return came with an equally massive risk of a catastrophic loss.

The whole point of risk adjusted return is to measure the quality of a return, not just its size. It prompts you to ask a much smarter question: “How much risk did I have to stomach to get this profit?”

Sometimes, a steady, drama-free 12% return is a far better achievement than a volatile 15% gain. This disciplined view helps you build a more resilient portfolio that can actually stand the test of time.

To make the comparison even clearer, let’s break down their key differences. <h3>Sharpe Ratio vs. Sortino Ratio Key Differences</h3> <table> <thead> <tr> <th align="left">Feature</th> <th align="left">Sharpe Ratio</th> <th align="left">Sortino Ratio</th> </tr> </thead> <tbody> <tr> <td align="left">Primary Focus</td> <td align="left">Measures return per unit of total risk</td> <td align="left">Measures return per unit of downside risk</td> </tr> <tr> <td align="left">Risk Measurement</td> <td align="left">Uses standard deviation (all volatility)</td> <td align="left">Uses downside deviation (only “bad” volatility)</td> </tr> <tr> <td align="left">Best For</td> <td align="left">General-purpose risk assessment for traditional portfolios</td> <td align="left">Evaluating investments with asymmetrical returns (e.g., hedge funds, growth stocks) or for conservative, capital-preservation strategies</td> </tr> </tbody> </table> This table neatly sums up why choosing the right tool for the job is so important. <h3>When to Use the Sortino Ratio</h3> So, when should you reach for this specialized tool? The Sortino Ratio really shines in a few specific situations: <ul> <li>Evaluating Asymmetrical Investments: It’s perfect for assets like hedge funds or certain high-growth stocks whose returns feature long periods of steady gains punctuated by either sharp rises or falls.</li> <li>For Conservative Investors: If your main goal is capital preservation, the Sortino Ratio gives a more accurate read on an investment’s ability to shield you from significant losses.</li> <li>Comparing Volatile Assets: When you’re looking at two investments with similar Sharpe Ratios but very different volatility patterns, the Sortino Ratio can be the tiebreaker, revealing which one is better at managing downside risk.</li> </ul> Ultimately, using both ratios gives you a much richer, more complete picture of an investment’s risk-adjusted performance. It’s about layering insights to make smarter, more confident decisions with your money. <h2>How Professionals Use Risk Adjusted Metrics</h2> <figure class="wp-block-image size-large"><img data-recalc-dims="1" decoding="async" src="https://i0.wp.com/cdn.outrank.so/6540ba8a-af29-418a-9ef5-c1e2a673f1e1/5dd412b1-853e-4e70-9f9a-7d60ea81cf60.jpg?ssl=1" alt="Image" /></figure> Knowing the theory behind risk-adjusted returns is one thing, but seeing it in the wild is where it really clicks. For financial pros, these metrics aren’t just abstract concepts from a textbook. They are the essential tools of the trade, driving smart decisions every single day. Portfolio managers, for instance, live and breathe these numbers. Their entire job revolves around building portfolios that not only chase high returns but also align with a client’s specific comfort level for risk. Using the Sharpe and Sortino ratios, they can compare different funds, stocks, and other assets on an apples-to-apples basis. This ensures every new addition to a portfolio is actually pulling its weight and delivering a worthwhile reward for the volatility it brings. The goal is always to build a balanced, efficient collection of assets.

Big financial institutions like banks and insurance companies depend on a similar, high-stakes framework called Risk-Adjusted Return on Capital (RAROC). RAROC is how these giants decide if a particular loan, a new business division, or a major investment is a good use of their capital once all the potential risks are tallied up. It boils down to the same fundamental question we ask as investors: “Is the potential reward here worth the risk I have to take?” <blockquote>A bank might use RAROC to evaluate a new type of small business loan. The interest rate might look attractive on the surface, but if the default risk is too high, the RAROC will be low. That’s a clear signal that it’s a poor use of the bank’s capital.</blockquote> This framework has been a cornerstone for measuring profitability for decades. Research on banking products, for example, has shown how tracking monthly RAROC can reveal whether a specific service is creating or destroying value for the institution. It’s a powerful tool that helps managers spot winning products and fix the ones that are lagging. <h3>How You Can Use This as an Individual Investor</h3> You don’t need to be a Wall Street quant to put this powerful mindset to work. The same logic can help you make much smarter decisions with your own money. Here are a few practical ways to start thinking like a pro: <ul> <li>Compare ETFs and Mutual Funds: Don’t just get dazzled by a fund’s advertised one-year return. Dig a little deeper and compare the Sharpe or Sortino ratios to see which fund was more efficient at generating its profits.</li> <li>Grade Your Own Strategy: Are you taking on a ton of risk just for mediocre returns? A quick risk-adjusted calculation can be a real eye-opener, showing you if your current approach needs a serious tune-up.</li> <li>Steer Clear of the Hype: That hot stock with explosive gains almost always comes with terrifying downside volatility. A risk-adjusted view helps you see past the noise and recognize when a steadier, less sensational investment is actually the better long-term choice.</li> </ul> <h2>Common Pitfalls and What to Watch Out For</h2> While risk adjusted return metrics are powerful tools, they are certainly not a crystal ball. A major pitfall is putting too much faith in historical data. Past performance, no matter how stellar, never guarantees what will happen next. A sky-high Sharpe Ratio from last year doesn’t make an asset immune to a market crash tomorrow. It’s also crucial to remember that these ratios don’t see the whole risk picture. Standard deviation is great for measuring price swings, but it’s blind to other, equally critical dangers that can sneak up on you. <ul> <li>Liquidity Risk: The danger that you can’t sell an asset quickly without taking a major haircut on the price.</li> <li>Geopolitical Risk: The threat of sudden, unpredictable events like international conflicts sending shockwaves through the markets.</li> <li>Systemic Risk: The scary possibility of a market-wide collapse that drags down nearly all assets with it.</li> </ul> <h3>Misinterpreting the Numbers</h3> Another common mistake is just assuming a bigger number is always better, no matter the context. Comparing the Sharpe Ratio of a volatile tech stock to that of a stable utility bond is a classic apples-to-oranges mistake. These metrics are most useful when you’re comparing similar types of investments. <blockquote>A risk adjusted return figure is a valuable piece of the puzzle, not the whole picture. It should be one of many tools used in a comprehensive analysis.</blockquote> At the end of the day, think of these tools as guides, not gospel. They offer a much smarter way to look at performance, but a holistic approach is still non-negotiable. This is why understanding <a href="https://finzer.io/en/blog/how-to-diversify-investment-portfolio">how to diversify an investment portfolio</a> remains a cornerstone strategy for managing the kinds of risks that a single number can never fully capture. <h2>Common Questions About Risk Adjusted Return</h2> Diving into investment metrics always stirs up a few questions. Let’s walk through some of the most common ones to make sure the concept of risk adjusted return is crystal clear. <h3>What Is a Good Risk Adjusted Return?</h3> There’s no magic number that works for everything, as “good” always depends on the context. You wouldn’t expect a government bond and a high-growth tech stock to have the same risk profile, right? That said, a useful rule of thumb for the Sharpe Ratio is that a value above 1.0 is considered good. This tells you an investment is punching above its weight, generating excess returns that are greater than the total risk it’s taking on. <ul> <li>1.0 to 1.99: A solid, efficient performance. The return is justifying the risk.</li> <li>2.0 or higher: This is excellent. It signals an investment that’s delivering outstanding returns for the level of risk involved.</li> </ul> If a ratio is below 1.0, it’s a sign that the returns might not be worth the headache of the risk you endured. The key is to always compare apples to apples-a tech fund’s Sharpe Ratio should be measured against other tech funds, not a basket of corporate bonds. <h3>Can a Risk Adjusted Return Be Negative?</h3> Absolutely, and it’s a major red flag when it happens. A negative risk adjusted return simply means the investment failed to even beat the return of the safest possible asset. For instance, if a fund you were in gained 2% for the year, but the risk-free rate (like a short-term Treasury bill) was 3%, the first part of your Sharpe Ratio calculation <code>(2% - 3%)</code> would be negative. <blockquote>A negative Sharpe or Sortino ratio is a clear signal of poor performance. It means you took on all the risks of the market for a return that was worse than if you had just stuck your money in the safest investment available.</blockquote> In this scenario, the investment didn’t just underperform; it failed to clear the lowest possible bar. It was an inefficient use of your capital for that time frame. <h3>Why Not Just Focus on the Highest Absolute Return?</h3> It’s tempting, isn’t it? Chasing the highest number is a common but dangerous trap for investors. An investment might boast a massive 30% gain, but what if getting there involved wild, gut-wrenching swings and a few near-death experiences for your portfolio? Was that truly a “good” investment? That shiny return came with an equally massive risk of a catastrophic loss. The whole point of risk adjusted return is to measure the quality of a return, not just its size. It prompts you to ask a much smarter question: “How much risk did I have to stomach to get this profit?” Sometimes, a steady, drama-free 12% return is a far better achievement than a volatile 15% gain. This disciplined view helps you build a more resilient portfolio that can actually stand the test of time. <hr /> Ready to stop guessing and start analyzing?
