I'm super curious to see if Nvidia turns out to be Enron 2.0..
But what happens if they can no longer sell those tangible goods at a massive profit, and they gave return to their roots selling to gamers? When the boom ends is when massive accounting fraud could happen.
They do, but that's not the (full) story here. Companies tend to easily migrate upwards, to a higher volume and/or higher profit margin market, and hardly (if ever) in the opposite direction. The painful restructuring necessary to enable this kind of reverse change is also damaging to the company brand, culture, and self-perception. If they ever get in such position, they may of course recover, but I wouldn't bet money on that.
