Built by QuantCommons' quantitative engine, this page is about relative opportunity, not data on RIO alone.

Period covered: RIO's full trading record, from June 1990 through September 2026. All returns include reinvested dividends. Data as of October 20, 2026.

## Key findings

- **Right now:** Over the past 6 months, RIO fell 9.7% while the S&P 500 rose 9.1%. Its metals & mining peers split over the past 6 months: SCCO (Southern Copper) rose 9.6%, while MP (MP Materials) fell 41.0%.
- **Stock or market?:** RIO rose 1.1% over the past 3 months, 2.2 points behind the metals & mining ETF PICK (iShares MSCI Global Metals & Mining Producers ETF), which rose 3.4%. The S&P 500 rose 3.9%. Its metals & mining peers did not move as one over the past 3 months: SCCO (Southern Copper) rose 17.6%, while MP (MP Materials) fell 14.6%.
- **Past 1 to 3 years:** RIO has outpaced the market, rising 30.1% over the past year against 15.8% for the S&P 500 and 17.9% for the Nasdaq 100.
- **Long term:** RIO turned $10,000 into $56,400 over the past decade, against $42,100 in the S&P 500. Even so, over 5 years RIO trailed the index: 77.9% against 81.7%.
- **In a crash:** Across seven sell-offs, RIO has typically fallen 1.6 times as far as the S&P 500. Even so, in the 2022 bear market, RIO held up better than SCCO (Southern Copper), FCX and VALE; only BHP (BHP Group) fell less.
- **Diversification:** Against the S&P 500, RIO has a correlation of 0.34 over 5 years, less closely than 62% of stocks worth at least $300 million.

## Common questions

### What was RIO's worst drawdown?

RIO's deepest decline since it began trading in 1990 was 89.0%, from May to December 2008. It took about 12 years from the low to climb back to its old high.

### What were RIO's best and worst years?

Over 29 full calendar years, RIO's best year was 2009, when it returned 195%. Its worst was 2008, with a return of -78.5%.

### Is there a better investment than RIO?

Among RIO's popular alternatives, CAT and BHP earned more than RIO over the past 5 years with similar volatility: CAT returned 31.1% a year at 31.9% volatility, against 12.2% a year at 29.0%. Looking beyond its popular alternatives, GLD (gold) and RTX (aerospace & defense) earned more than RIO with less volatility over the past 5 years. GLD returned 17.7% a year at 18.9% volatility, against 12.2% a year at 29.0%.

### Is RIO more volatile than the S&P 500?

Yes. RIO's volatility over the past 5 years was 29.0%, 1.7 times the S&P 500's 17.1%. Volatility measures how widely returns swing around their average: in roughly two years out of three, RIO's return lands within 29.0% 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 RIO's Sharpe ratio?

RIO's Sharpe ratio over the past 5 years was 0.54, against 0.79 for the S&P 500, so RIO earned less 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 RIO with the S&P 500?

Over the past 5 years, RIO's monthly returns had a correlation of 0.34 with the S&P 500. Correlation runs from 1 (moving in lockstep) through 0 (unrelated) to −1 (moving in opposite directions). They are only loosely linked, which makes it a real diversifier next to an index fund. In the table, the correlation column measures each option against RIO instead: the lower it is, the more that option would diversify a RIO holding.

### What are the best alternatives to RIO?

Of the 19 popular alternatives we compared, eight outperformed RIO in at least 3 of 5 short-term and 2 of 3 long-term timeframes, with dividends reinvested: TGB, STLD and SCCO.

### Did RIO outperform the S&P 500?

RIO finished ahead of the S&P 500 (SPY) in 17 of 29 full calendar years. In 2025, it returned +44.5%, against +17.7% for the index.

### How did RIO do in stock market crashes?

RIO fell less than the S&P 500 (SPY) in six of the ten major crashes it has traded through, and further in four. The clearest case was the dot-com bust, when RIO fell 33.9% and the S&P 500 fell 47.5%.

### What diversifies RIO?

These had a low correlation with RIO over the past 5 years and still earned a positive 5-year return: among large ETFs, DXJ (correlation 0.30), EMLP (correlation 0.35) and HDV (correlation 0.42); among large stocks, CAH (correlation 0.06), CLS (correlation 0.01) and FIX (correlation 0.01). A correlation near zero means the two have moved largely independently.
