Here is the yearly performance for every single fund that Ark is running. Keep in mind that some of them have existed for barely a year if that, but the point still stands.
ARKK (ARK Innovation ETF) - 54% down.
ARKW (ARK Next Generation Internet ETF) - 50% down.
ARKG (ARK Genomic Revolution ETF) - 53% down.
ARKQ (ARK Autonomous Tech. & Robotics ETF) - 25% down.
ARKF (ARK Fintech Innovation ETF) - 53% down.
ARKX (ARK Space Exploration & Innovation ETF) - 18% down.
I am not trying to attribute such performance exclusively to poor decisions, not at all. There is definitely a good amount of unforeseen circumstances that drove ARK ETFs down. But it is difficult to consider ARK's actions as a good source of predictions for tech companies they get involved with, given that 4 out of 6 of their funds are over 50% down in a year, and the rest are still down by a significant amount.
