Is it working?

ARKK is trailing the index this year: +8.5% versus +13.7%.

Over the past month ARKK returned -5.5% while the S&P 500 made +1.0%. The holdings that hurt most: Tempus AI Inc (-14%, 6% of the fund), Robinhood Markets Inc (-18%, 4% of the fund), Twist Bioscience Corp (-15%, 4% of the fund).

Over the past year the gap is wider: ARKK returned -7.3% against +15.8% for the S&P 500, 23 points apart.

The 110-point five-year shortfall is the hangover from ARKK's Feb 2021 peak. The fund fell 81% from that high by Dec 2022 and still sits 46% below it. Five years ago was close to the top, so the five-year number captures almost the whole fall.
