Schrödinger’s Market


Quantum physicist Erwin Schrödinger once came up with a thought experiment to illustrate a difficult conceptual problem. Suppose you have an opaque box with a cat inside. In the box is a mechanism that is designed to release a poison gas based on the random actions of subatomic particles on a quantum level.

Now according to quantum theory, it is literally impossible to know what these particles will do in advance. You cannot even accurately measure what they are currently doing beyond general probabilities. In fact, until you observe them they act as though they are doing multiple mutually exclusive things—including behaving as though they are two places at once!

Hence Schrödinger’s box. Without observing the contents of the box you have no way of knowing if quantum action triggered the poison or not. Thus, until you open the box and look the cat is simultaneously alive and dead: a surprising conclusion, and a difficult paradox for physicists!

You and I can leave that problem to the scientists, but Schrödinger’s box can be a useful metaphor for other unknowable states. The actions of financial markets are theoretically not as complicated as quantum mechanics. But predicting market action is so far beyond our current mathematical understanding that they might as well be.

Like quantum particles, the value of a market cannot accurately be measured without interacting with it. This leads to a great deal of uncertainty and can sometimes make it feel like multiple conflicting realities are true at once.

Reading the financial press you will often be presented with competing headlines declaring that we are simultaneously in the midst of a great bull market and a terrible bear market.

As with the box, we prefer to leave these paradoxes to people with more time on their hands. Instead of trying to time the market, we believe in sticking to timeless principles like avoiding stampedes and finding bargains in the hopes of finding quality companies. We cannot predict what market prices will do from moment to moment, but we can guess at general probabilities.
