Is it working?
This year ARKK is ahead of the market — +14.7% against +12.6% for the S&P 500.
ARKK has beaten the index by 7 points over the past month (+5.9% vs -0.7%), led by Circle Internet Group Inc (+39%, 4% of the fund), Tesla Inc (+11%, 9% of the fund), Robinhood Markets Inc (+22%, 4% of the fund).
That five-year gap — 111 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 43% below that peak today. Any comparison that starts near the top of that boom looks brutal.
