The Globe and Mail reports in its Saturday edition that SpaceX shares jumped 19 per cent in their Nasdaq debut Friday, sending the company's value past $2-trillion to make it the sixth-biggest U.S. company by value and turning Elon Musk into the world's first trillionaire (all figures U.S.). A Reuters dispatch to The Globe says investors jumped at the chance to get a piece of Mr. Musk's sprawling empire spanning rockets, satellites and artificial intelligence after the record-setting $75-billion IPO. More than 510 million shares worth $84-billion changed hands, even though SpaceX is unprofitable and generates relatively little revenue. The launch was smoother than many observers expected, with the shares ending the day at $160.95 to bring its value to $2.1-trillion. Investors across the spectrum, from large institutions to retail fans of Mr. Musk, ended the day euphoric. "For many investors, SpaceX is the closest thing to investing in the railroads during the Industrial Revolution and they are willing to pay the Elon Musk premium for that opportunity," said Seth Hickle at Mindset Wealth Management in Indianapolis. However, analysts and investors said investors should brace for volatility in the early days of trading.
