In a word, yes -- in a number of cases, companies try to buy themselves out of the stock market, for that and other reasons (like the tyranny of quarterly earnings reports and shortsighted boards of directors).
We're off on a tangent now. We've left the original topic. And the original topic was resolved by noting the WSJ Dartboard Contest, where managers had every incentive to show what they could accomplish, but instead they failed, spectacularly, in public, for years.
