Introduction

Adaptive Markets by Andrew W. Lo Adaptive Markets explores financial evolution. Even if you have never invested a dime, your life is still affected by the market. If you sought a job after the 2008 financial crisis, you know how reliant banks and businesses are on a healthy economy.

There is no reason today's powerful financial system should be stuck in old ways of doing things. It is time we thought big and put the system to work for the betterment of the whole world.

Efficient Market Hypothesis

The Efficient Market Hypothesis is the most widely accepted theory for how the market works. If you have taken an Economics 101 course, you have likely heard about the predominant theory of how markets work the Efficient Market Hypothesis, or EMH for short. In a nutshell, EMH theory suggests that the price of stocks, bonds, and similar investment assets will always provide an accurate reflection of a company's health, profitability, and general value. In recent years, it has become widely accepted that the EMH is not perfect.

However, academics and leading experts in the investment sector still regard it as the best theory out there. To see the EMH in action, let us look at Morton Thiokol, which helped make rockets for NASA in the 1980s. This included the faulty equipment that caused the Challenger space shuttle explosion in 1986. It made perfect sense that the value of Morton Thiokol shares plummeted in the minutes following the Challenger disaster.

The company had just encountered a serious setback. The EMH works because it takes into account the collective wisdom of all investors. They constantly analyze the market and reflect their best assessments of how well businesses will do. This is shown in the price they are willing to buy and sell their assets at.

It is generally agreed that by putting together all these active financial minds, you will get a fairly accurate reflection of a company's value. Given this high regard for the EMH's accuracy, it is also considered highly unlikely that anyone can beat the market. This would involve spotting something everyone else has missed. Since you cannot beat the market, the standard advice is to join it by investing in long-term, low-risk index funds or mutual funds.

These comprise a collection of stocks that will remain more or less untouched over time. By sticking with index funds for a long period, a patient investor can expect to take advantage of the stock market's gradual increase in value over time. These standard principles of EMH led John Bogle to create the Vanguard Index Trust, the first mutual fund in 1976. Since then, the index and mutual fund businesses have become a multi-trillion dollar staple of the finance industry.
