Marathon Digital (NASDAQ:MARA) stock dipped 5.1% in late afternoon trading on Monday after disclosing that it may sell as much as $750M of new securities. After Friday's close, the bitcoin miner said it may sell common stock, preferred stock, warrants, units, or a combination of those securities from time to time and use the proceeds to buy more bitcoin mining servers. Stocks often fall when a company announces plans to sell new shares because that reduces the percentage stake held by existing shareholders. Last Friday, SA contributor BOOX research explained its bullish view on Marathon Digital.
