The Intelligence Portfolio Theory: Introduction

Nobel laureate Harry Markowitz’s Modern Portfolio Theory (MPT) will celebrate its 70th anniversary this year. It has revolutionized the finance industry by formalizing the principle of diversifying an investment portfolio and taken up much of the computing time of the world’s powerful financial computers and the minds of managers for decades. It’s the free lunch of finance.

Today, we tackle this mountain by proposing a new slope in which to climb it: The Intelligence Portfolio Theory (IPT).

The difference between MPT and IPT is ontological. The first focuses on the statistical effects of randomness; the second focuses on the self-organizing intelligence of interacting systems.

Randomness, as we shall see, is a mathematical convenience of ignorance, and this convenience presents many false noses.
