Is it working?
This year ARKK is behind the market — +11.4% against +14.1% for the S&P 500.
Over the past year the gap is wider: ARKK returned -4.0% against +17.3% for the S&P 500, 21 points apart.
That five-year gap — 110 points — mostly comes down to timing. Five years ago ARKK was trading close to its all-time high of Feb 2021. It then fell 81% to its low in Dec 2022, and it is still 44% below that peak today. Any comparison that starts near the top of that boom looks brutal.
| To date | 1 month | YTD | 1 year | 5 years |

| S&P 500 (SPY) | +2.2% | +14.1% | +17.3% | +85.1% |
| Nasdaq-100 (QQQ) | +3.4% | +18.8% | +21.3% | +103.1% |
