Cathie Wood's Ark Investment Management bought more shares in self-driving trucking company $TuSimple(TSP.US)$ on Tuesday, which has lost nearly 70% in market value so far this year.
The stock-picking firm bought 21,619 shares in TuSimple, estimated to be worth $232,620 based on their last close of $10.7 a share.
TuSimple has slumped about 38% in the past week. It is currently trading much below its April IPO price of $40.
Ark Invest owns shares in TuSimple via two of its six exchange-traded funds — the $ARK Innovation ETF(ARKK.US)$ and the $ARK Autonomous Technology & Robotics ETF(ARKQ.US)$.
The St. Petersburg, Florida-based money managing firm held 11.4 million shares — worth $122.5 million— in TuSimple, before Tuesday's trade.
The latest purchase represents a marginal boost to Ark Invest's stake but adds up to more than a 2% jump in the past week when the money managing firm loaded up more shares.
TuSimple's unexpected management shuffle last week saw co-founder and CTO Xiaodi Hou taking over the CEO and chairman roles from Cheng Lu.
Although the company said it was part of a "planned executive succession," the move spooked investors, sending its shares down 21% on Thursday and 13% lower a day later.
Wood had said she had "confidence in Xiaodi's ability to execute on TuSimple's autonomous strategy."
TuSimple is developing commercial-ready, Level 4, fully autonomous trucks for customers. Ark Invest has also placed bets in electric vehicle companies $Tesla(TSLA.US)$ and $XPeng(XPEV.US)$.
