I have a hard time imagining how spx stock will drop to a reasonable price. You have to be a true believer at its current valuation, so who is going to sell? Maybe if enough insiders or stock options start selling it will drop.
How many of the HODLers will be SpaceX believers, vs. Musk believers? Musk's already only narrowly avoided being banned from running publicly traded companies from the $420 tweet years back.
