Yes but only if its added before the index funds. Let's just hope that the nasdaq and the other markets just don't take spacex (Nasdaq is literally bending its rules to accodomate SpaceX)
The worst thing is that we don't even have a say in all of this and chances are most likely that its gonna IPO and get listed on the index funds soon and once it gets into Index funds, a lot of collateral damage might happen.
I must say that I am not quite optimistic about there not existing collateral damage, there is happening a lot of corruption within financial markets in general with bending laws. The worst part is that we all would/might be the most impacted by it all
Total market cap of NASDAQ 100 (QQQ) is $40 trillion, SpaceX joining that and immediately going to zero would be a 5% drop, big but not the worst we've seen.
If SpaceX joins and goes to zero, that is firstly a 2 Trillion dollar wipeout and the whole market would absolutely go completely crazy and the market would be so spooked as @etempleton suggests that instead of it being a 5% drop, it would be more like 50% (don't quote me on it) but still, the markets would absolutely drop substantially more than 5% & it might erode the trust within financial markets altogether for many people too because of such massive wipeouts of funds.
