How Seagate Technology (STX) compares with the whole market and its popular alternatives
Built by QuantCommons' quantitative engine, this page is about relative opportunity, not data on STX alone. It places STX (Seagate Technology Holdings plc) against 17 popular alternatives, its neighboring categories and the entire market of over 10,000 U.S.-listed stocks and ETFs, and surfaces what has done better on consistent outperformance, return for the risk taken, behavior in real market crashes and diversification. The result is a clearer view of where STX stands in the market, and of the alternatives worth a closer look.
Period covered: STX's full trading record, from December 2002 through September 2026. The crash tests reach back to 2000 using older funds and the S&P 500. All returns include reinvested dividends. Data as of October 20, 2026.

Key findings
- Right nowSTX is 38.2% below its high, bear-market territory, while the S&P 500 sits 1.3% below a record. STX has gone against the market, falling 15.8% over the past 3 months while the S&P 500 rose 3.9%. At a glance ↓
- Stock or market?The weakness is STX's own: it fell 15.8% over the past 3 months while the computer hardware ETF VGT (Vanguard Information Technology ETF) rose 6.3%. The S&P 500 rose 3.9%. Its computer hardware peers did not move as one over the past 3 months: DELL (Dell Technologies) rose 21.3%, while WDC (Western Digital) fell 25.2%.
- Past 1 to 3 yearsOver the past year, STX rose 217% against 15.8% for the S&P 500 and 17.9% for the Nasdaq 100. The same gap shows up over 3 years (975% against 89.3%). By year ↓
- Long termSTX turned $10,000 into $280,000 over the past decade, against $42,100 in the S&P 500. STX's 10-year return of 2,698% puts it ahead of 99% of the stocks worth at least $300 million with that much history. The S&P 500 returned 321%. Growth of $10,000 ↓
- In a crashSTX fell harder than the S&P 500 in five of six sell-offs. The Covid crash was the exception: STX fell 25.6%, less than the S&P 500's 33.7%. Crash tests ↓
- DiversificationAgainst the S&P 500, STX has a correlation of 0.58 over 5 years, more closely than 87% of stocks worth at least $300 million.

How much would $10,000 in STX have grown?
This chart tracks a hypothetical $10,000 investment in STX over the past 23 years, with dividends reinvested, alongside the same amount in the S&P 500, investments that ended ahead of STX over the same span and STX's popular alternatives, among those that traded for the entire period. A second view covers the past 5 years, the period the better options further down the page are judged on. It shows not only where each investment ended up but also how smooth or uneven the path was.
Note: STX began trading on December 11, 2002, so the chart cannot reach back to the dot-com bust. It covers the most recent 23 years of STX's record, starting at the end of September 2003.
- $10,000 invested in STX at the end of September 2003 would have grown to $713,300 by September 2026, more than the $116,093 it would have become in SPY, an S&P 500 fund.
- Five of the eight other investments on the chart ended ahead of STX, and NVDA finished highest, at $18,839,668.

STX against the whole market
Where STX ranks among every stock and fund, and what across the market has done better.
How does STX rank among all stocks?
This section ranks STX on return, volatility, risk-adjusted return and worst decline against every stock worth at least $300 million with enough history. Where the comparisons with its popular alternatives show how STX stacks up against its peers, these rankings show where it stands in the market as a whole.
- STX's 5-year return ranks in the top 1% of the 2,893 stocks worth at least $300 million with 5 years of history.
Ranked against U.S.-listed stocks worth at least $300M that have enough history for each measure, so the count changes from row to row; smaller stocks are left out. Lower volatility and smaller declines rank higher.
| Measure | STX | Rank | Standing |
|---|---|---|---|
| 1-year return | +217% | 30 of 3,287 | top 1% |
| 3-year return | +975% | 31 of 3,017 | top 1% |
| 5-year return | +866% | 22 of 2,893 | top 1% |
| 10-year return | +2,698% | 24 of 2,202 | top 1% |
| Volatility, 5 years | 48.7% | 1,868 of 2,893 | bottom 36% |
| Sharpe ratio, 5 years | 1.18 | 27 of 2,893 | top 1% |
| Worst decline, past 10 years | −57.0% | 760 of 2,187 | top 35% |
What has beaten STX on both return and risk?
Each dot is an investment, placed by how much it earned a year over the past 5 years (higher is better) and how much its price swung, its volatility (further left is calmer). STX sits where the dashed lines cross. Anything in the green box above and to the left earned more than STX with smaller swings, a better trade-off over this period on both counts. Past results are no promise, but a name in the box is worth a closer look.
- One stock worth at least $500 million sit in the green region: each earned more than STX over the past 5 years with smaller price swings. That is fewer than 1% of the 3,633 screened. Few investments beat it on both counts.
- Among those with at least half STX's swings, ATI has the best return for its risk: 61.8% a year at 42.9% volatility, 12% less than STX's 48.7%, and a Sharpe ratio (return above cash per unit of volatility) of 1.34 against 1.18 for STX.
Annual return is the annualized total return with dividends reinvested, and volatility the annualized swing in daily prices, both over 5 years. Labeled dots are the strongest picks from the table below and the names called out above, colored by how close they sit to STX. 3,633 stocks and funds worth at least $500 million were screened.

Is there a better investment than STX?
Investments that beat STX over the past 5 years on return, volatility, drawdowns, consistency, crash losses or fees, from its popular alternatives out to the whole market.
- Among STX's popular alternatives, MU was ahead of STX in most short and long periods.
- Few investments have done better on both counts: only one of the 3,633 stocks and funds worth at least $500 million earned more than STX with less volatility over the past 5 years, among them ATI.
How this works
The table below lists investments that beat STX over the past 5 years on at least one of these measures: a higher annual return with lower volatility, a higher annual return at similar volatility, a similar return with lower volatility, a higher Sharpe ratio with a smaller worst decline, a higher total return in most periods from 3 months to 10 years, or smaller losses in recent market crashes. It checks STX's popular alternatives first, then the rest of its own and neighboring categories, then every stock and fund worth at least $500 million, and shows the strongest few in each group. The full list of those with a higher return and lower volatility than STX follows the table.
Annual return is the annualized total return with dividends reinvested. Annual return, volatility and the Sharpe ratio cover 5 years; the worst decline covers the past 10 years. Green marks a better figure than STX's. "On the frontier" means no other option shown or tested earned more with less volatility. Funds that hold the same thing are shown once. Beyond the popular alternatives, nothing with more than 1.5× STX's volatility counts as better.
These figures cover the past 5 years. Green marks a better figure than STX's.

What these numbers mean for STX
- Annual return
- STX returned 57.4% a year over the past 5 years with dividends reinvested, against 12.7% a year for the S&P 500. At that pace, $10,000 became about $96,600. Annual return is the steady yearly rate that would produce the same total result, so investments held over the same span compare fairly. Guide: What is performance and return? →
- Volatility
- STX's volatility over the past 5 years was 48.7%, 2.8 times the S&P 500's 17.1%. Volatility measures how widely returns swing around their average: in roughly two years out of three, STX's return lands within 48.7% of its average, either way. The higher it is, the rougher the ride and the harder it is to hold through a slump. Guide: Understanding and measuring risk (volatility) →
- Sharpe ratio
- STX's Sharpe ratio over the past 5 years was 1.18, against 0.79 for the S&P 500, so STX earned more for each unit of risk than an index fund did. The Sharpe ratio is the return earned above cash for each unit of volatility: two investments with the same return are not equal if one got there with far bigger swings. Guide: Balancing reward with risk (Sharpe ratio) →
- Worst decline
- STX's worst fall from a peak to a low over the past 10 years was 57.0%, against 33.7% for the S&P 500. Losses and gains are not symmetric: climbing back from a 57.0% fall takes a 133% gain. Guide: Market crash risk and tail risk →
- Correlation
- Over the past 5 years, STX's monthly returns had a correlation of 0.58 with the S&P 500. Correlation runs from 1 (moving in lockstep) through 0 (unrelated) to −1 (moving in opposite directions). They often move together: some diversification next to an index fund, but not a cushion. In the table, the correlation column measures each option against STX instead: the lower it is, the more that option would diversify a STX holding. Guide: Correlation and diversification →

How did STX do year by year?
This table shows each investment's total return in every full calendar year since 2003, along with where STX ranked among its popular alternatives each year. Annual results reveal how consistently each one kept pace with STX and how far its good and bad years diverged, detail that multiyear averages tend to smooth over.
Note: STX began trading on December 11, 2002, so the table starts with 2003, its first full calendar year, and cannot show how it fared during the dot-com bust.
- Ranked against its popular alternatives each year, STX finished in the top quarter in seven of 23 years and in the bottom quarter in three. In 2025, it ranked 3 of 17.

Risk and diversification
How STX has fallen, how it held up in crashes beside the S&P 500 and its popular alternatives, and what moves independently of it.
What were STX's worst declines?
A drawdown is the decline from a peak to the lowest point before a new high. This section presents STX's five deepest drawdowns since it began trading in 2002, alongside the S&P 500's return over the same dates, and how long each took to recover. Together, these figures show how much an investor could have lost and how long it took to get back to even.
Note: STX began trading on December 11, 2002, so this list cannot include the dot-com bust. The crash tests on this page show how older funds and the S&P 500 fared through those years.
- In all five of STX's worst declines, the S&P 500 held up better over the same dates.
- Not every decline was the market's doing: STX fell 70.0% from December 2014 to May 2016, while the S&P 500 rose 2.0%.
- The slowest recovery came after STX fell 65.8% from October 2003 to August 2004; it did not regain that peak until November 2007, three years later.
Green means STX fell less than the S&P 500 over the same dates. Based on daily closing prices with dividends reinvested.

How did STX do in stock market crashes?
This section measures how far STX, the S&P 500 and each alternative fell from peak to trough during every major market crash since 2000. A smaller decline means an investment held up better, and comparing results across crashes shows whether that resilience was consistent or a one-off.
Note: STX began trading on December 11, 2002, so its row reads "Not yet trading" for the dot-com bust. The older alternatives and the S&P 500 show how those crashes played out.
- STX fell further than the S&P 500 in seven of the nine crashes it has traded through. The clearest case was the 2015 China and oil sell-off, when STX fell 48.9% and the S&P 500 fell 12.8%.
- Among its popular alternatives, AVGO held up best, falling less than STX in seven of the eight crashes they both traded through.
- STX began trading after the dot-com bust, but nine of its popular alternatives lived through it. The mildest fall among them was IBM's 58.3%, against 47.5% for the S&P 500.
Newest crash first. Each figure is the fund's deepest fall within the crash window; green means a smaller fall than STX.

How closely does STX move with the S&P 500?
Upside capture measures how much of the S&P 500's gains an investment kept in the months the market rose, and downside capture how much of its losses it took in the months the market fell. An investment that captures more of the gains than the losses has compounded ahead of the market over time. This section compares STX with its popular alternatives on both measures, and on beta (how strongly each has moved with the market), over the past 10 years.
- Over the past 10 years, STX captured 169% of the S&P 500's gains in rising months and 88% of its losses in falling months, with a beta of 1.58. Its share of the market's gains was larger than its share of the losses.
- Only DELL had a higher capture ratio (upside capture divided by downside capture) than STX's 1.93, out of 16 popular alternatives with the same record.
- DELL took just 43% of the S&P 500's losses, against 88% for STX, while still keeping 154% of its gains.
Monthly total returns over the past 10 years, measured against SPY. 100% capture or a beta of 1.00 means moving in line with the S&P 500. Green marks a better figure than STX's: more upside, less downside or a higher capture ratio. Sorted by capture ratio.

What diversifies STX?
Correlation measures how closely two investments move together, on a scale from 1 (in lockstep) through 0 (unrelated) to -1 (in opposite directions). This section lists large ETFs and stocks whose returns have had a low correlation with STX's. Because such investments tend not to fall at the same time, pairing STX with them can reduce a portfolio's overall swings.
- Moving a fifth of the money in STX into MPC would have cut the portfolio's volatility by 18% over the past 5 years for a small cut in its annual return (+66.7% for STX alone, +66.6% for the mix).
- FIX made money in six of the seven calendar years in which STX lost money.
- Among large ETFs, LVHI, DXJ and EMLP have moved largely independently of STX over the past 5 years, with correlations of 0.24 or lower, and each still earned a positive 5-year return.
Only ETFs with at least $1.0B in assets and stocks worth at least $10B, with a correlation below 0.5 over the past 5 years and a positive return, are included, ranked by Sharpe ratio; funds that hold the same thing are shown once. The year columns are the years in which STX lost money. The last two columns show a portfolio that is 80% STX and 20% the other investment, rebalanced monthly.

Common questions
What was STX's worst drawdown?
STX's deepest decline since it began trading in 2002 was 88.7%, from November 2007 to January 2009. It took about three years from the low to climb back to its old high. Because STX launched in December 2002, that record does not include the dot-com bust.
What were STX's best and worst years?
Over 23 full calendar years, STX's best year was 2009, when it returned 313%. Its worst was 2008, with a return of -82.0%.
Is there a better investment than STX?
Among STX's popular alternatives, MU was ahead of STX in most short and long periods. Few investments have done better on both counts: only one of the 3,633 stocks and funds worth at least $500 million earned more than STX with less volatility over the past 5 years, among them ATI.
Is STX more volatile than the S&P 500?
Yes. STX's volatility over the past 5 years was 48.7%, 2.8 times the S&P 500's 17.1%. Volatility measures how widely returns swing around their average: in roughly two years out of three, STX's return lands within 48.7% of its average, either way. The higher it is, the rougher the ride and the harder it is to hold through a slump.
What is STX's Sharpe ratio?
STX's Sharpe ratio over the past 5 years was 1.18, against 0.79 for the S&P 500, so STX earned more for each unit of risk than an index fund did. The Sharpe ratio is the return earned above cash for each unit of volatility: two investments with the same return are not equal if one got there with far bigger swings.
How correlated is STX with the S&P 500?
Over the past 5 years, STX's monthly returns had a correlation of 0.58 with the S&P 500. Correlation runs from 1 (moving in lockstep) through 0 (unrelated) to −1 (moving in opposite directions). They often move together: some diversification next to an index fund, but not a cushion. In the table, the correlation column measures each option against STX instead: the lower it is, the more that option would diversify a STX holding.
What are the best alternatives to STX?
Of the 17 popular alternatives we compared, one outperformed STX in at least 3 of 5 short-term and 2 of 3 long-term timeframes, with dividends reinvested: MU.
Did STX outperform the S&P 500?
STX finished ahead of the S&P 500 (SPY) in 14 of 23 full calendar years. In 2025, it returned +225%, against +17.7% for the index.
How did STX do in stock market crashes?
STX fell less than the S&P 500 (SPY) in two of the nine major crashes it has traded through, and further in seven. The clearest case was the 2015 China and oil sell-off, when STX fell 48.9% and the S&P 500 fell 12.8%.
What diversifies STX?
These had a low correlation with STX over the past 5 years and still earned a positive 5-year return: among large ETFs, LVHI (correlation 0.22), DXJ (correlation 0.24) and EMLP (correlation 0.20); among large stocks, CAH (correlation -0.00), CLS (correlation 0.45) and FIX (correlation 0.49). A correlation near zero means the two have moved largely independently.
How we measure
- Short-term periods are 1M, 3M, 6M, YTD, 1Y; long-term periods are 3Y, 5Y, 10Y. An investment outperformed in a period when its total return, with dividends reinvested, was higher than STX's. Returns within 0.5 points or 3% of STX's, whichever is larger, count as a tie.
- "Qualified" means outperforming in at least 3 of 5 short-term periods and 2 of 3 long-term periods. "All-weather" means outperforming in every long-term period and all but one short-term period.
- Popular alternatives are the funds and stocks most often compared with this one. We include only those that trade today, are not leveraged or inverse, and hold at least $200 million.
- Volatility is the annualized standard deviation of daily returns over 5 years, a measure of how much the price typically swings in a year. The Sharpe ratio is the return above cash for each unit of that volatility.
- A decline, or drawdown, runs from a peak to the lowest close before the next high. The worst decline ever uses all the price history we have; comparisons between funds use the past 10 years so that younger funds are judged on the same stretch.
- Sector overlap is the share of assets two funds hold in the same sectors. Correlation and the mixed-portfolio figures use monthly returns.
- Upside and downside capture follow Morningstar's definition: the compound monthly return in the months the S&P 500 rose (or fell), divided by the S&P 500's compound return in those months. Beta measures how strongly monthly returns have moved with the S&P 500. All three use the same window for every investment.
- Figures are computed from daily adjusted prices and update after each trading day. Past performance does not predict future results.
