SpaceX could remain under pressure as more insiders gain permission to sell. Here are the key dates

Don't expect the rough ride in SpaceX to be over anytime soon. SpaceX has yet to trade on the public markets for a full week, but the stock has already proven volatile. After a blockbuster IPO on June 12, the Elon Musk-led rocket maker has seen its market cap surge past Amazon and even Microsoft , before dropping back down. The stock is already more than 28% off its recent peak, and even briefly fell below its $150 opening price. It was last at around $161. That selling pressure isn't expected to let up anytime soon , especially as lockup expiration periods expire and more insiders gain permission to sell. SpaceX debuted with only about 5% of its roughly 13 billion outstanding shares, meaning more will become available in the coming months — and add to the volatility around the stock. Typically, companies opt for lock-up periods of 90 to 180 days to prevent insiders from selling the stock immediately after its IPO, and to help stabilize the stock. But SpaceX has opted for a schedule that allows lock-ups to expire over time.
