I remember a interesting exchange that Taleb had written in one of his books either the “ Black Swan” or “ Fooled by randomness”, I cant recollect which one.
In one of the customary morning meetings that are part of all securities firms one of the traders asked him what would he assign a higher probability to the markets going up or down next week. Taleb’s view was that he would assign a higher probability of the markets going up.
The trader asked him his follow up question on what Taleb’s position was. He replied he was going short on the market which of course perplexed the trader.
It is a interesting exchange. The trader of course missed the point that what is important is not just about the probability of the market moving in a particular direction but how much can the market move in a particular direction.
So there could be a 70% probability of the market moving up 10% and a 30% probability of the market moving down 40%. The payoff in the probability matrix of the market moving down is much higher.
Why did this thought cross my mind? The current market seems to be poised at a interesting juncture. Though the momentum seems to indicate a higher probability of it moving up, the quantum of downside if it plays out will be much higher.
