Mordrak, some quick responses, without doing a chain quote:
The stock market was presumably, originally designed to benefit the participants (companies and investors). But the government has been involved at various times, so you could say that the government influences the design as well. I think it is quite useful to society, as a means to pool risk and allocate capital. It’s certainly not perfect, but then, what large institution is?
Yes, companies can choose to divide profits between reinvestment, dividends, and/or stock purchases. That’s pretty much the norm, in fact, though I simplified things for my examples. (Not all companies do both stock purchases AND dividends, but I think most eventually do one or the other if they’re successful, and larger companies may do both).
You’re correct that companies can’t exert as much control over the market as they can over their own business.
I’d look at it this way:
The performance of a company’s stock is primarily a reflection of two things:
- The performance of the company itself, and the market’s assessment of its future prospects.
and
- Market-wide factors. Over time, the market reprices capital and risk. i.e. In harsh times, the market may demand a higher rate of return for ALL risky companies. To achieve the higher (future) rate of return, prices drop.
This is kinda confusing, but an example may clarify:
Going back to my earlier example, if the market values a non-growing company at a P/E of about 12, and that company can pay out all of it’s earnings as either dividends or stock buybacks, then that means that for $100 of stock value, the company is paying out about $8.33 in earnings. i.e. Investors should earn about 8.33% on this investment. Now, let’s say the market gets panicky, and across the board some investors flee from stocks and those who remain demand higher rates of return. Let’s say the new equilibrium return rate for a company like our example is 10% (up from 8.33%). Since the company itself isn’t earning more or less than it was before, to reach that equilibrium returng, the company’s share price must fall, to about $83.33. People who buy at that price will get earnings of about $8.33 for a price of about $83.33. But of course, investors who had held the stock before got hammered - they absorbed a price drop of almost 17%.
Re: the other part - the market assessing an individual company’s prospects. Yes, that is certainly tricky. If the market (as a whole) is kinda stupid, then CEO’s can ‘trick’ the market by focusing on short term profits, which the market may mistake as sustainable in the long term. But the market as a whole is surprisingly good at estimating the long term chances of a company. The market will pay a large premium for a company with the potential for fast earnings growth. In contrast, even if a company is making a big profit today, if the market perceives that the earnings are likely to fall, the market will probably not pay a whole lot for the stock. It’s a guessing game, but the fact that so very few people are able to out-guess the market (i.e. beat the market), means the market is doing a pretty good job, IMO.
Re: the flood of new capital into new industries. Yes, the market can overshoot, injecting too much capital into such industries, causing a bubble. (The concept of bubbles is debateable though - sure it’s easy in hindsight to say internet stocks were in a bubble in 99-00, but it’s much tougher to be confident of that in real time). Conversely, the market can undershoot, not injecting enough capital into fast growing industries. I’m not totally up on the relevant history, but arguably, the market underestimated the potential of PCs and PC software for much of the 80s and early 90s - if the market knew the value of the franchise that Microsoft was establishing, the price of Microsoft stock might have been higher, sooner, and the market might have been willing to fund more competitors. I think part of the possible over-reaction of the market to internet stocks from roughly '95-'00 was because the market realized it had been slow to react to the PC and PC software industry a few years earlier, though for the 'net, they arguably overreacted the other way.
