Pi (1998)

Trader's Film Library #9 · Markets and trading in fiction. A psychological portrait of the pursuit of a perfect pattern.

Original title: Pi · Type: film · Created by: Darren Aronofsky · Usefulness for traders: ★★★☆☆

What it's about

Brilliant mathematician Max Cohen searches for a pattern that will predict the stock market. His obsession attracts a Wall Street firm and a group of mystics, and drives him to the brink of madness.

What it has to do with markets

The film is a metaphor for the obsession with finding patterns in chaos. It's exactly the mechanism I call the clustering illusion in the Atlas of biases: the brain sees patterns even where there are none.

Lessons for traders

• not every pattern in the data is real (the clustering illusion, Atlas of biases #4)
• an obsession with the “perfect system” harms your health and your results
• the market has no hidden code to crack

What to watch out for

An art film, black and white, unsettling. It's not about trading, but about a mind that wants too badly to understand it.
