> the stock price of a company has no direct bearing on its capital. Only at IPO time or when a company is raising additional capital is the stock price relevant for the capital. E.g. Google's stock price has increased 15x since their IPO, but that has had no effect on their capital. Any other time besides the IPO and when raising additional capital, it is just money changing hands between stockholders, the company doesn't see any of that.

But all the capital decisions are in the context of the stock price. If an outside group looks at investing, that will be in terms of current shares; if the company gets bought by another or does a merger, that transaction will be determined by the current share price.

> Secondly, the market is frequently very wrong about pricing stocks. It was happily 'allocating capital' to internet stocks during the dot-com bubble, to financial stocks up to 2008

Some of those internet stocks were worth far more than even their inflated valuations at the time (of course, many were worthless). The market price is always going to be a best-guess consensus estimate, sure, but a lot of these things are just inherently hard to figure out how much they're actually worth.
