> Data as of October 20, 2026. Total returns include reinvested dividends. Past performance does not predict future results; nothing here is investment advice.

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 now:** STX 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%.
- **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 years:** Over 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%).
- **Long term:** STX 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%.
- **In a crash:** STX 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%.
- **Diversification:** Against 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. Next to an index fund it is some diversification, but not a hedge. Over 10 years, STX's beta versus the S&P 500 was 1.58: in the S&P 500's rising months it gained 1.7 times as much as the index, and in falling months it lost 88% as much.
- **Better options**
  - **Popular alternatives:** MU (Micron Technology) was ahead of STX in most short and long periods.
  - **Whole market:** 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 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.

- $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.

### Is there a better investment than STX?

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.

- 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.

## 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.

### 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).

- 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.

## 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.
