I lurk here enough that I
think this hasn't been posted but apologies if something relevant has.
I have never bought an individual stock, and I'm an anxious enough person that I try not to read the financial news, so I failed to notice that Apple has bought hundreds of billions of dollars of its own shares
for the past half-decade or so and
plans to keep doing so indefinitely.
Here's the stupid question: this should, in the long run, and independent of everything else, lower Apple's share of VTSAX (or, you know, the actual total market it tracks) and increase its P/E… right?
The model I have in my head is that Apple makes a certain amount of money per unit time: they distribute some of those to public shareholders in the form of dividends, they distribute some of that to their employees in the form of salary and stock compensation, and, lately, they sit on some of it, which should raise their stock price by value of the money they're sitting on divided by the number of stocks. (Of course, since the actual stock price is set by the market, it's not obvious that we would be able to separate that from all the other fluctuations.) As they buy back shares from the public, the individuals people who sell get a one-time cash out, Vanguard sells to follow the market (meaning that we get some cash too), and more of all future profit gets to go to their employees and less gets to go to us. You could even imagine Apple becoming a privately-held company if this went on long enough, in which case our share of the profits, if all we held was VTSAX, would be zero.
That feels wrong, because the implication is that passive investing could have a big problem in a few decades. On the other hand, private equity owns more and more of the market every year. And, while it's been a few years since I pretended to read Piketty's book, I seem to recall that might have been the point there too.
Of course, none of this matters at all if Apple ceases to sell things at a price higher than what it cost them to make them, but, all other things being equal, does that sound at all correct?
