Cathie Wood's money managing firm Ark Invest on Wednesday further raised its exposure in $Robinhood Markets(HOOD.US)$ as shares of the financial services company tanked after reporting earnings for the latest quarter.

Ark Invest bought 2.24 million shares — estimated to be worth $79.4 million — in Robinhood Markets on the day the stock tanked 10.44% to $35.44 a share.

Robinhood reported third-quarter revenue of $365 million after hours on Tuesday, up 35% year-over-year but missed analysts’ estimates of $431.3 million.  The company noted a decline in cryptocurrency activity during the quarter.

The company noted the cryptocurrency decline was partly due to a fall in demand for Dogecoin (CRYPTO: DOGE), which touched an all-time high of $0.74 in May the first and has plummeted 66.3% since then.

Ark sold Robinhood shares via the $ARK Innovation ETF(ARKK.US)$, the $ARK Fintech Innovation ETF(ARKF.US)$, and the $ARK Next Generation Internet ETF(ARKW.US)$ on Wednesday. No other Ark Invest ETF owns shares in the company.

Wood's investment management firm held 9.73 million shares — worth $385.36 million — in Robinhood ahead of Wednesday's trade.
