The theatrics of the June 25, 1968 close of trading in the fresh egg futures market involved two steps: first, the clearing of the market by simultaneously buying all the wide ranging offers pending at the time, followed by a bid at the maximum price allowed by Chicago Mercantile Exchange rules. The market had been trading tentatively for a few weeks, poised to either rally or decline, in part because none of traders, including the author of the June 25 drama, David Henner, really understood what was happening with demand and supply of the underlying asset of this particular asset.
