this is not investment advice, but it's the method elon musk has come up with to nibble away at the money of completely ordinary investors, people who invest in indexes, and the money in pension funds.
the s&p made the right call by not adding it to the index. yes, with this rush, it'll bring money to those looking for action who'll hit and run in a day or two, but the money of most individual investors and people with investments in pension funds is going to get nibbled away too.
the company is already going public at twice the valuation it should be, it has never seen a profit and is constantly posting losses, and it's impossible for it to see a profit anytime soon.
but elon knows where he'll find the money, and spacex investors, with their shares in a firm that has never seen a profit since the market opening, will fleece the ordinary investor like always.
