Elon Musk-owned SpaceX shares have fallen in 10 of the past 11 trading sessions, hitting a fresh post-IPO low of $119.68. This represents a decline of 47% from its post-listing high of $225.64, and a drop of 25% from its first-day opening price of $160.95. The sell-off has erased more than $1 trillion from the company's market capitalisation.
