Poor analogy for multiple reasons, not similar enough to make the point. There is a difference between having no profits and intentionally obscuring profits.
The trend is more fake numbers papering over everything until it doesn't, which is NOT the same as it has been.
These "sharp" fund managers are just buying with abandon at this point - they aren't fiduciary geniuses they have their eye on commissions.
Unprofitable, relatively new and small at the time, Amazon beating profitable, well established giant Walmart? Nah, not a poor example at all, and plenty similar. It was the latest new thing at the time. Now Tesla is.
Tesla is not the same as Amazon, but it's also not completely unprofitable. Tesla has had four consecutive quarters of profits, beating expectations.
Is Tesla's stock overvalued? Is it going to crash soon? Possibly. Not a problem for people who invest long term in low cost index funds that cover well over 11,000 companies in the US and abroad, and well over 9,900 US bonds.
I believe you misunderstood me regarding fund managers. No, they are not fiduciary geniuses, but that's irrelevant. I think of them as hardened criminals, who take your money with their commissions and managed fund high fees in exchange for negligible to no benefit. I always recommend low cost index funds instead.
