Perf 10Y
10-year return
💡 What is Perf 10Y (10-Year Return)?
Perf 10Y (Performance 10 Years) is a measure shown as a percentage (%) that tells you how much a stock's price has gone up (or down) over the last 10 years. Simply put, it's like a "long-term investment report card showing how much you would have made (or lost) if you had bought this stock 10 years ago."
Here's an analogy: If you had put 1,000,000 KRW into a bank fixed deposit 10 years ago, it would be worth about 1,200,000~1,300,000 KRW today. But what if you had put that same amount into Apple (AAPL) stock during the same period? It could have grown to 7,000,000~9,000,000 KRW or more. That's what Perf 10Y does — it shows at a glance "how well this investment performed over a long period of 10 years."
10 years is a very meaningful timeframe in the investing world. Over that period, you usually go through at least one economic expansion and one recession, along with several market corrections and crises. Because of this, a 10-year return reflects a company's true long-term competitiveness and ability to create value — not just short-term luck or good timing. Companies that have consistently delivered high returns over the past 10 years can be seen as proven businesses that have survived many market downturns.
The S&P 500, which represents the U.S. stock market, has a historical average annual return of about 10%. Compounded over 10 years, that's roughly 159%. In other words, if a stock's 10-year return is above 159%, it beat the market average; if it's below that, it performed worse than just investing in an S&P 500 index fund. Keeping this benchmark in mind is useful when evaluating the long-term performance of individual stocks.
📅 Comparing Returns Across Different Time Periods
Return metrics come in many different timeframes. Since each timeframe tells a different story, comparing returns across multiple periods helps you make more accurate investment decisions.
Short-Term Return (1 week ~ 1 month)
Reflects recent momentum and market sentiment. Heavily influenced by news, earnings releases, and market events. Important for short-term traders, but only a reference point for long-term investors. A high short-term return does not guarantee good long-term performance.
Medium-Term Return (3 months ~ 1 year)
Reflects mid-term trends and business performance. Because it includes several quarters of results, it's more reliable than short-term returns. However, it can still be strongly affected by the overall market mood (bull vs. bear market).
Long-Term Return (3 years ~ 5 years)
Reflects the company's medium-term growth ability and competitiveness. It covers part of an economic cycle but may not include a full cycle. A solid 5-year return shows value as a growth stock, but you need to compare it with 10-year data to judge sustainability.
Very Long-Term Return (10 years, Perf 10Y)
Shows the company's true long-term value creation ability. It reflects the performance of companies that survived and grew through at least 1-2 economic cycles and several market crises. This is the period where the compounding effect is maximized, making it the best measure of the power of long-term investing.
Let's look at NVIDIA (NVDA) as an example. Its 1-year return sometimes exceeded 200% during the AI boom, and during the semiconductor downturn it experienced -50%. But its 10-year return shows a stunning performance of several thousand percent. This proves that, despite short-term ups and downs, the company created enormous long-term value.
📊 How to Interpret a 10-Year Return
Outstanding Performance (+500% or more, ~20%+ annualized)
An exceptional long-term result that significantly beats the market average. Companies like Apple (AAPL), Microsoft (MSFT), NVIDIA (NVDA), and Amazon (AMZN) fall into this category. Achieving this over 10 years requires continuous innovation, an expanding market, and a strong competitive advantage.
Excellent Performance (+160~500%, ~10~20% annualized)
Good performance that beats the market average. Solid growth companies like Visa (V), Home Depot (HD), and UnitedHealth (UNH) belong to this group. These are suited for investors who want stable returns that are still better than the market.
Market-Level Performance (+50~160%, ~4~10% annualized)
Similar to or slightly below the market average. For returns in this range, it may be more efficient — given the time and effort required to analyze individual stocks — to simply invest in an S&P 500 index fund (SPY, VOO).
Weak Performance (below +50% or negative)
Cases that significantly underperformed the market over a long 10-year period, or recorded losses. This suggests serious problems such as weakening structural competitiveness, industry decline, or management failure. A typical example is Intel (INTC), whose 10-year return has been poor as it fell behind in semiconductor competition.
When interpreting a 10-year return, it's important to understand the compound interest effect. A 15% annualized return doesn't simply equal 150% over 10 years — it compounds to about 305%. And 20% annualized compounds to roughly 519%. Compounding becomes more powerful the longer time goes on, which is exactly why Warren Buffett said, "Time is a friend of good businesses."
🔄 Combining It With Other Return Metrics
Perf 10Y + Perf 5Y Comparison
If the 10-year return is high but the recent 5-year return is low, the company may have performed well in the past but recently lost growth momentum. Conversely, if the 10-year return is average but the 5-year return is very high, the business has recently improved dramatically. For example, a large portion of NVIDIA's 10-year return came from its 5-year return, because the AI revolution only really took off recently.
Perf 10Y + Dividend Yield Combination
Perf 10Y only reflects stock price appreciation and does not include dividends. Dividend stocks like Coca-Cola (KO) or Johnson & Johnson (JNJ) may look like they're below the market average based on price gains alone, but their total return — with reinvested dividends — can be much higher. So for dividend stocks, it's a fairer comparison to calculate the total return (Perf 10Y + cumulative dividends).
Perf 10Y + Volatility Combination
Two companies can reach the same 10-year return but have very different volatility. A company that climbed steadily to 300% feels completely different from one that wildly swung up and down on the way to 300%. The latter may have endured drawdowns of more than -50%, leading many investors to sell in panic at the bottom. Stability along the way matters just as much as the final return number.
Perf 10Y + Revenue/Earnings Growth Combination
Check whether the stock return is supported by revenue and earnings growth. If the 10-year return is high but revenue growth is low, the gain may have come from valuation expansion (like rising P/E ratios). That kind of return tends to be less sustainable. In contrast, companies whose revenue and earnings grew steadily along with the share price have healthier, more sustainable gains.
🎯 Practical Ways to Use the 10-Year Return
1. Screening Long-Term Investment Candidates
Look at companies whose 10-year return has consistently beaten the S&P 500 as candidates for long-term investment. These companies are likely to have a durable competitive advantage (a "moat"). Apple's ecosystem, Microsoft's cloud transition, and Visa's payment network effect are all examples of moats that supported long-term performance. However, past performance does not guarantee future results, so you must verify whether the company's current and future competitive advantages are still intact.
2. Measuring Excess Return Over the Market
Subtracting the S&P 500's return over the same period from an individual stock's 10-year return gives you the "Alpha," or excess return over the market. For example, if a stock's 10-year return is 400% and the S&P 500 rose 200% over the same period, the alpha is 200 percentage points — meaning the stock earned roughly twice as much as the market.
3. Identifying Long-Term Industry Trends
Comparing the 10-year returns of several companies in the same industry reveals broader long-term industry trends. If most tech companies have high 10-year returns and energy companies generally lag, that reflects structural change in the economy. Understanding these big-picture shifts helps you pick industries likely to keep growing.
4. Building Pension/Retirement Investment Plans
The 10-year return is a very useful reference for long-term investment planning, especially for building retirement savings. For instance, based on the S&P 500's historical 10-year return (about 150~200%), you can simulate how much wealth you might build by investing a fixed amount every month over 20~30 years. Past returns don't guarantee future results, but they help you set reasonable expectations.
⚠️ Cautions When Looking at 10-Year Returns
First, past performance does not guarantee future results. This is the most basic rule of investing, but it's easy to forget when looking at stocks with strong long-term returns. GE (General Electric) was once America's top company, but it then delivered heavy losses to investors over the next 10 years. IBM was once the undisputed leader of the tech industry, but it lagged in the cloud transition and saw poor 10-year returns.
Second, the starting point can dramatically change the return. If the starting point was just after the 2009 financial crisis (when stock prices were at the bottom), the 10-year return will look very high. If it was the dot-com bubble peak in 2000, it will look low. So instead of relying on a single 10-year return from one starting point, comparing returns across multiple periods leads to more balanced judgments.
Third, it does not include dividends. Perf 10Y only captures changes in the stock price itself. Companies like AT&T (T) that pay high dividends but have limited share price growth will look weak if you only look at Perf 10Y. Such companies should be evaluated using their total return (with reinvested dividends) for a fair comparison.
Fourth, watch out for Survivorship Bias. The stocks you can see a 10-year return for are only the ones that have "survived" those 10 years. Companies that were delisted or went bankrupt during the period are not included. Therefore, the average return of surviving stocks can overstate actual investment results. Keep in mind that there were once-promising companies that disappeared.
✅ 10-Year Return Checklist
☑ Did you compare it with the S&P 500's return over the same period to check performance vs. the market?
☑ Did you compare it with other timeframes (5 years, 3 years, 1 year) to spot recent trends?
☑ Did you check the total return, including dividends?
☑ Did you analyze the driver of the high return — revenue/earnings growth or valuation expansion?
☑ Did you confirm whether the past competitive advantage is still valid today and in the future?
☑ Did you compare the long-term returns of competitors in the same industry to gauge relative performance?
❓ Frequently Asked Questions (FAQ)
Q. Can I invest now in a stock that has a high 10-year return?
A. A high 10-year return means the stock did well in the past — it does not guarantee it will do well in the future. That said, companies with a long track record of strong returns are likely to have a powerful competitive advantage, so check whether that advantage is still intact before deciding. You should also make sure the current valuation (P/E, EV/Sales, etc.) isn't excessively high. Even great companies produce poor returns if you buy them at too high a price.
Q. Is it true that the S&P 500 index fund beats most individual stocks?
A. It is close to true statistically. In fact, about 80~90% of actively managed funds underperform S&P 500 index funds over periods of 10 years or longer. The same tends to hold for individual investors. So if you don't have the time and skill to analyze individual stocks deeply, periodically investing in an S&P 500 index fund (SPY, VOO, etc.) can be the most efficient strategy. Warren Buffett himself has directed in his will that his estate be invested in an S&P 500 index fund.
Q. How do I evaluate a company that has been listed for less than 10 years?
A. Companies that have been public for less than 10 years don't have Perf 10Y data, so use the longest available return (5 years, 3 years, etc.) as a substitute. Note that the shorter the period, the less reliable the data. As an alternative, focus mainly on fundamental metrics like revenue growth and earnings growth, and treat the post-IPO return as supplemental reference. Just as it would have been hard to predict Tesla's long-term success from its early returns after its 2010 IPO, don't use short-period returns to draw definitive conclusions about the future.
Q. Are there stocks with negative 10-year returns?
A. Yes, there are. Stocks whose price is lower than 10 years ago are likely to have serious structural problems. This includes industries in long-term decline (traditional media, some oil companies), companies that have fallen sharply behind competitors (Intel in certain periods), or firms that have gone through management crises. Before attempting a "it's at the bottom now, so it must recover" contrarian bet on such stocks, always check whether the structural issues are actually being resolved. Trying to catch the bottom in a long-term value-destroying company is very risky.
🇰🇷 Notes for Korean Investors
Always factor in currency effects. When a Korean investor looks at a 10-year return of a U.S. stock, the return in KRW can differ from the return in USD. If the exchange rate was 1,100 KRW/USD 10 years ago and is now 1,350 KRW/USD, you get an additional gain of about 23% just from currency movement. Conversely, if the KRW has strengthened, your return can shrink. When building a long-term investment plan, consider possible exchange rate changes as well.
Use the power of compounding. Korean tax-advantaged accounts such as ISA (Individual Savings Account) or pension savings accounts can be used to invest in U.S. ETFs while receiving tax benefits, maximizing long-term compounding. If you plan to invest for 10 years or more, actively using these tax-advantaged accounts to boost your after-tax return is a smart strategy. In particular, long-term holdings of S&P 500 index ETFs (SPY, VOO) or Nasdaq 100 ETFs (QQQ) inside pension accounts are frequently recommended by many experts.
Compare it with the Korean stock market. The 10-year return of Korea's KOSPI index has often been significantly lower than that of the U.S. S&P 500. This is due to the so-called "Korea Discount" in the Korean market and the fact that global tech giants are concentrated in the U.S. This comparison helps explain why many Korean investors invest in U.S. stocks, and at the same time highlights the importance of global diversification.
Consider Dollar Cost Averaging (DCA). No matter how strong the 10-year return of a market or stock is, investing a large lump sum at once carries timing risk. Investing a fixed amount every month or every quarter naturally gives you the effect of buying more when prices are low and less when prices are high. Spreading investments out over a long 10-year period using DCA can deliver more stable returns regardless of market swings.
