The title and thesis don't match the data. This has nothing to do with whether a corporation is privately or publicly held, and everything to do with where it is in its lifecycle. The actual assertion made, which the evidence does match, is that younger companies are harder to value because uncertainty over growth and future margins is much higher. Seems pretty obvious.
