With regard this week’s market debacle, the question, of course, is whether this was simply a blip – yet another one-day BTFD opportunity – or the start of something bigger and worse. The answer, we think, depends on how the media Narrative surrounding the week takes shape over the next several days. Right now the media Narrative about the week is in complete disarray, because there was no obvious “reason” for the sell-off. Or rather, there were too many possible reasons, from bad earnings reports to the Argentina default to worries about a strong jobs number to Espirito Santo cracking up to new Russian sanctions to just a generic “we were overdue for this”. From a game theory perspective, this sort of seemingly out-of-the-blue sharp move had very little to do with anything that happened this week, but is a natural by-product of the Common Knowledge Game in action.
