random walks

Soooooo....many stock prices fell yesterday. It is an event depleted of sound or fury, and if things slide a bit more today it might signal yet more selling, and so on. Alien races that observe the Earth for entertainment are no doubt perplexed by stock markets. That people seek to assign future value to things is a necessary part of civilization, but for this value to swing so much on a day to day basis is absurd. No one makes the future, certainly not shareholders. This thing called "The Market" represents nothing more than the sum total of many poorly informed, superstitious idiots.
