Cathie Wood-led Ark Invest on Friday sold more shares in $Tesla(TSLA.US)$, continuing to book profit in a stock that remains its largest bet.

Ark Invest sold a total of 28,345 shares — estimated to be worth $28.83 million based on Friday's closing  — in the electric vehicle maker. 

Tesla shares closed 1.32% higher at $1,017.03 a share on Friday. The Elon Musk-led company's stock has risen 39.4% so far this year.

Ark Invest sold the shares via the $ARK Innovation ETF(ARKK.US)$ and the $ARK Autonomous Technology & Robotics ETF(ARKQ.US)$ and also holds the stock via the $ARK Next Generation Internet ETF(ARKW.US)$ on Friday. 

Tesla's weight in ARKK and ARKW has slipped below the 10% threshold at 8.29% and 9.26%, respectively, as of Friday's closing. In ARKQ, it still constitutes 10.8% of the portfolio.

The three ETFs held 2 million shares — worth $2.05 billion — in Tesla, ahead of Friday's trade. 

Ark Invest has been booking profit in Tesla since September — selling over $3 billion worth of shares — after years of piling up shares in the electric vehicle company at far lower levels. 

Tesla continues to be the money managing firm's biggest bet across ETFs — a stock it predicts would hit the $3,000 mark by the end of 2025. Wood favors the automotive industry's switch to electric vehicles and recently bought into $XPeng(XPEV.US)$ but has said she wouldn't buy the recently listed $Rivian Automotive(RIVN.US)$ at the current high valuations.
