No, there are a huge number of companies that are valued reasonably for their revenue / profitability / growth.

There's basically two stock markets: things valued on fundamentals and things valued on vibes.

And I don't think there's ever going to be a unified theory of value that can span both, because the former is quantitative and the latter is psychology.

Stocks can start paying dividends in the future: MSFT did not in the past, and does now. AAPL did, stopped in the 1990s, and started doing so again.

You should be indifferent to the company's dividend scheme since it's the underlying business activity that drives total returns, and not its distribution policy. There is all sorts of magical thinking when it comes to dividends:

A pyramid scheme can run out of people to keep it going: the stock market is in a sense a 'savings scheme' for future consumption. Younger people work and turn their cash into savings, older people take their savings and turn it back into cash: as long as young people need to think about the future, and older people / retirees need to pay bills, there's a mechanism to maintain this cycle.

True, and it's a common question that comes up: What's the point of owning a stock if it doesn't pay a dividend? How do you participate in the company's performance?

There are other ways for performance to translate to the investors directly. For example, if the company sells itself then all the shareholders will get that payout. Stock buybacks are a thing. And, as other commenters here have said, eventually the company may start paying a dividend

But, you're not entirely off-base in that you're just buying into the vibes of a company. It's just that most of the time (much of the time?) those vibes have been rooted in some semblance of rationality, that there was something of value behind the shares you're buying. That is definitely not universally true anymore

Aren't buybacks the new dividends?

It’s only a pyramid scheme for Tesla, SpaceX or X formally known as Twitter see a pattern there?
