(Bloomberg) -- Coinbase Global Inc. sank to a record low as investors fled high-flying market newcomers. The operator of the largest U.S. cryptocurrency exchange tumbled as much as 7% to $254.02 on Thursday, slumping for a fourth straight day. That left the shares in danger of breaching the $250 reference price for its April direct listing. An exchange-traded fund that tracks shares of companies that recently went public plunged for an eighth day, the longest slide since 2015. Virgin Galactic Holdings Inc. and Opendoor Technologies Inc., companies that came to market through blank-check offerings, sank more than 5%.
