You can probably thank Cathie Wood for that.
On the first couple of days since Robinhood made its market debut in an IPO hosted on its own app, ARK Funds' online tally of its trading activity showed that the several funds controlled by Wood had purchased a total of more than 3.1 million shares of Robinhood.
Today, however, ARK disclosed that just one single fund -- the ARK Innovation ETF (ARKK 0.69%) -- now owns 4.9 million shares of Robinhood.
Within the grand scheme of things, that's still not a lot. According to ARK Innovation's report, Robinhood shares still make up barely 0.8% of the total value of its holdings. That being said, it was presumably Investor's Business Daily and other publications' highlighting of ARK's interest that sparked a renewal of other investors' interest in the still unprofitable stock broker.
And thanks to today's surge, for the first time since its IPO, Robinhood stock is finally trading above its $38 IPO price.
