SpaceX shares closed at $154.63 on Monday, down around 16% on the day. That leaves them within touching distance of the $150 at which the shares first changed hands when public trading opened, the level set once underwriters finished building the order book, though still some way above the $135 price at which the IPO itself was struck.
The slide has erased more than $600 billion (€524.2bn) in market value over three trading days, dragging the company down from a peak that had lifted it past Amazon and, fleetingly, Microsoft, in terms of market capitalisation.
