NVDA - how on earth do you value this thing?

I have always struggled to place a valuation on this company. Every time I’ve tried to value it, I come to the conclusion that it’s overvalued so I avoid buying it, and then the stock just goes up and up and up.

It’s a fantastic business - leading player in its industry, high margins etc. but I struggle to get to 2.9 trillion in market cap given the amount of free cash flow the business is generating isn’t even 1/10th of that.

Anyone have any tips or insights on how to approach it?

Right now the only reason why I’m tempted to buy the stock is because it’s a great business that’s fallen significantly from its ATH, but even that’s not a sufficient reason for me to buy it because my gut feeling tells me that there is still no margin of safety.

Sometimes I think I’d be a lot wealthier if I didn’t follow Graham/Buffett principles 😂
