Maybe check your own knowledge on the topic you're commenting on before talking down on others. Musk for example has famously said himself on several occasions that he thinks Tesla is overvalued. But any company with a >1000x P/E ratio is less screaming "sensible investment" and more "get on the train before it moons" meme-stock. Regardless, none of this is rational anymore. It is mostly hype (and a little bit of insiders rug-pulling each other).
