Earlier quoted context omitted.
I don't think I can follow your argument. What's intrinsic value? The market is supposed to arrive at a fair value for a stock (and there's no reason to assume it doesn't because that would create arbitrage opportunities). If you buyback at the fair value no shareholder value is created or destroyed, the only change is in the ownership of the assets and future dividends.
Don't stock buybacks basically transfer wealth from the company to the shareholders? The major advantage this has over other means of transferring wealth is that shareholders get to realize their gains with only capital gains tax applied, rather then the much higher dividend tax rate.
What is peculiar is that this act has nothing to do with running a company well in the long term, yet is the most immediate way executives can improve their "performance based compensation". Execs seem to have found a hack around stock based compensation that biases companies towards divestiture over investment, and the short-term minded shareholders are onboard with this scheme at the expense of long-term minded shareholders.
This looks largely like a bug in the executive compensation system...I'm curious what kinds of fixes are going to come out of the world of MBA academia.
