1, 2 and 4 were expected and incorporated in the price, 3 was a nothingburger. A good valuation takes into account the risk that anything which is expected fails for some reason, so when the expected stuff happens, it should increase the valuation by removing the risk. But it's never a game changer that should increase the valuation by a factor of 15.
Weird, I thought #3 was by far the most exciting of the 4. It outlined the path to the tipping point where EVs with decent range are cheaper than low end ICE cars.
