Well actually most of the time it is speculation and media manipulation.
The scum at the top will pump and dump. As well as deride and devalue in time to come and take control with their purchase of stock at penny's in the dollar of the original valuations. The scum at the top always take out true competition to what they own and they don't give a shit if you lose.
Is Musk trying to highlight this to his many sycophants? And maybe make them a few dollars even though it will take from others.
Remember the GameStop Stock fiasco? What that boiled down to was - "How dare people use their gut and independent research instead of listening to experts they will never meet in real life!"
Yes, the uproar was focused on the loss of control by the industry power brokers. A lot of people got burned during that also, but a few common millionaires made out big.
Took me only a minute to realize why Gamestop stocks shot up faster than an Elon Musk rocket - People were trapped at home needed something to pass the time and video games filled the void.
