Well, stock price is not a good short term indicator about Nvidia developments, nor any company for that matter. Nvidia is doing a very good job. That being said, their stock is absolutely and hilariously overvalued.
NVDA's forward PE is ~37, about what it has been for the past ~5 years I've been tracking that. So it's not overpriced based on that metric. If you're convinced the stock is that overvalued, go short some or, if you like to live dangerously, buy some long-term put options (don't be an idiot and buy short-term options.) I have no idea if NVDA is like Cisco Systems in 2000, or if it's something unique. What I am aware…
This doesn't make much financial sense. Since every T-Bill is held by someone the amount of T-Bill outstanding is completely determined by government issuance. And since the amount of T-Bill outstanding will only grow over time, no "money" will ever flow out of it. Now if you narrow you inclusion of T-Bill holders to a specific group of people the amount this group holds could certainly go up and down over time. But then I wonder how you know this group sold stocks to buy T-Bills, and why this is more significant than the action of their counterparties: every share they sold was bought by someone else after all.
