Against the world ETF
Over 26 years, from December 2000 to October 2026, the share did not clearly beat the world ETF once risk is accounted for. It earned more, but shaking 2.3 times harder: once that risk is counted, it did about as well as the ETF.
$10,000 placed at the end of December 2000 are worth today
| Tetra Tech | $75,804 |
| World ETF | $65,117 |
| S&P 500 | $91,204 |
| Risk-free placement | $15,894 |
The risk
- Shaking:the share moves 2.3 times as much as the world ETF.
- Worst fall:-69Â % between December 2000 and September 2002. $10,000 placed at the top fell to $3,133. The world ETF, at worst: -53Â %. Back to its high in 14 months.
Tetra Tech earned more than the world ETF since 2000
Value of $10,000 placed at the end of December 2000, dividends reinvested, in dollars
- Tetra Tech: $75,804
- World ETF: $65,117
- S&P 500: $91,204
- Risk-free placement: $15,894
Share price without dividends; the world ETF and the index reinvest theirs. A dividend payer is therefore understated here.
Based on past performance. This is not a recommendation.
