| Jun 17, 2014 at 0:53 | comment | added | Steven Landsburg | It appears that the entire construction is based on identifying the times at which inequalities of the form $P_i>P_j$ are reversed, with $P_i$ the price of the $i$th stock. But the units in which any given price is measured are totally arbitrary, because a company worth (say) \$1000 can issue 1, 10, 100 or 1000 shares of stock, making the price per share equal to \$1000, \$100, \$10, or \$1. This makes it near-impossible to believe that inequalities of the form $P_i>P_j$ have any significance at all. | |
