Today, stock markets and other markets such as bonds and currencies can best be described as “automated automation.”

Here’s what I mean...

Stages - Stock - Investing

There are two stages in stock investing.

The first is coming up with a preferred allocation among stocks, cash, bonds, etc. This stage also includes deciding how much to put in index products or exchange-traded funds (ETFs, which are a kind of mini-index) and how much active management to use.

Stage - Buy - Sell - Decisions - Sidelines

The second stage involves the actual buy and sell decisions — when to get out, when to get in and when to go to the sidelines with safe-haven assets such as Treasury notes or gold.

What investors may not realize is the extent to which both of these decisions are now left entirely to computers. I’m not talking about automated trade matching where I’m a buyer and you’re a seller and a computer matches our orders and executes the trade. That kind of trading has been around since the 1990s.

Computers - Portfolio - Allocation - Buy/sell - Decisions

I’m talking about computers making the portfolio allocation and buy/sell decisions in the first place, based on algorithms, with no human involvement at all. This is now the norm.

Eighty percent of stock trading is now automated in the form of either index funds (60%) or quantitative models (20%). This means that “active investing,” where you pick the allocation and the timing, is down to 20% of the market. Although even active investors receive automated execution.

Amount - Market - Making - Sense - %

In all, the amount of human “market making” in the traditional sense is down to about 5% of total trading. This trend is the result of two intellectual fallacies.

The first is the idea that “You can’t beat the market.” This drives investors to index funds that match the market. The truth is you can beat the market with good models, but it’s not easy.
