Roku’s slump on Friday came on the back of a disappointing second quarter, with the company missing both top- and bottom-line expectations. Following the earnings report, a slew of analysts downgraded the stocks and reduced their price targets.

Cathie Wood’s firm, however, is optimistic about Roku. A revised valuation framework for the company released earlier this month showed the firm expects Roku shares to rally to $605 by 2026.

Ark Trims Robinhood Holdings: Ark’s ARKF sold 37,570 shares of trading app Robinhood Markets, Inc. (NASDAQ:HOOD). At Friday’s closing price of $9.05, the sale would have fetched ARK about $340,000.

Roku settled Friday’s session at $65.52, down a whopping 23.07%, and Robinhood edged down 0.66% to $9.05, according to Benzinga Pro data.
