Fooled by Randomness

The year is 1999. In a downtown Manhattan trading floor, a man named John is the star of the desk. He has been the star for four years running. His trades have not failed. His returns have not disappointed. His confidence, the particular velocity of it, fills the room. Colleagues watch how he talks to salespeople. They study how he positions himself relative to the screen. He drives a Ferrari. He has a second apartment in Tribeca. He believes, with absolute sincerity, that he has figured out how markets work.

He has not. He has just been lucky for long enough to believe otherwise.

In the same building, occupying a different corner of the same floor, a man named Nero Tulip is doing something that looks, from the outside, like almost nothing. He is cautious. He caps his upside deliberately. He reads philosophy in the slow hours. He does not drive a Ferrari. He does not discuss his system with colleagues. He is not the star of anything. He makes modest returns year after year and quietly refuses to take positions that could blow up his account. His colleagues consider him overly timid. A few feel sorry for him.

Then the market breaks. John loses everything -- not slowly, not partially, but completely, in the specific catastrophic style of someone who had borrowed heavily against a position that moved against him. The Ferrari gets sold. The apartment in Tribeca gets sold. John gets reassigned and eventually terminated. He spends years afterward trying to explain what happened, but the explanation keeps sliding toward bad luck, bad timing, forces beyond any reasonable anticipation.
