Ark Invest CEO Cathie Wood has been selling off a growing amount of Tesla shares this month, opting instead to splurge on lately plummeting technology firms that the legendary Wall Street investor believes could rebound again soon, joining a spate of insiders cashing out of Tesla stock.

According to Ark's daily transaction records, the firm's flagship Ark Innovation ETF sold another 41,457 shares of Tesla on Thursday, for a total of $31.4 million, bringing the total sales across Ark's funds this month to $266 million.

Though Tesla is Ark's most prominent position, it is also the stock that the firm has sold the most in September, topping sales of Nintendo, Swiss pharmaceutical major Roche Holding, and software firm Trade Desk, all of which totaled around $50 million.

Instead, Ark has been pouring money into New York-based automation startup UiPath, spending more than $185 million for about 3.4 million shares this month, only weeks after the robotics company's price plummeted 20% from an all-time high.

The investment firm has also spent $96.5 million and $80 million on Roku and Zoom Video Communications stock, respectively, two tech firms that surged last year during the height of pandemic fear but have subsequently lost up to 50% of their value.

Although Ark has yet to reply to Forbes' request for comment, Wood told an audience of investors on Tuesday that she believes the market will soon begin to favor growth and innovation businesses, rather than the sectors hardest hit by the pandemic earlier this year.

Pfizer, Invitae, and Fate Therapeutics are among Ark's other top purchases this month, a cloud computing startup PagerDuty, cryptocurrency exchange Coinbase, and healthcare companies Pfizer, Invitae, and Fate Therapeutics.
