These shares are going crazy. Part of the reason is that they are effectively a new listing. A private company, Nikola Corporation, has been bought by a quoted company, VectoIQ, whose only asset is some $235m in cash provided by another company, Iveco, which makes trucks. On completion of the transaction, on 3 June, VectoIQ changed its name to Nikola Corporation, which has become a quoted company in which Iveco, part of CNH Industrial, has a stake.
