Yeah, but let's more than double that - and say they make $100B of revenue per year. That's still a Price / Sales ratio of 10 ! Price to sales, not price to ear

Yeah, but let's more than double that - and say they make $100B of revenue per year. That's still a Price / Sales ratio of 10 ! Price to sales, not price to earnings !!! You never know, maybe this AI thing is not just hype (I think it is for now), and maybe NVidia will basically own the future of AI computing chips - if that's the case, then okay - this valuation will be OK - but this valuation is here, now ! And a huge company stock price is moving by 20-30%. This is absolutely bonkers. Know, a lot of financial reporting happens on periodical basis (be it end of day or month) - it kind of assumes that things are not moving too wildly and you can put some trust in it. Which is usually the case for big companies. But lately, we see those top N companies in US, with prices having huge swings. I wonder, what are the implications of that.
