The Chinese philosopher Confucius once said that life is very simple, but we insist on making it complicated. You could say the same thing about investment.
Complexity in investment often goes with a lack of transparency. The highly engineered and multi-layered financial derivatives that contributed to the global financial crisis five years ago are a case in point. These products were problematic for investors as it was very difficult to understand how they were designed, how they were priced and whether the proposed payoffs were right for their own needs.
In contrast, there are far fewer mysteries about the underlying stocks and bonds traded each day on public capital markets, where prices are constantly in flux due to news and the ebb and flow of supply and demand. From these millions of securities, diverse portfolios can be built around known dimensions of return according to the appetites and needs of each individual.
The competitive nature of public capital markets, the efficiency of pricing and the difficulty of getting an edge are what underpin the ‘efficient markets hypothesis’ of Professor Eugene Fama, who recently was awarded the Nobel Prize in economics.
The practical takeaway from Fama’s work is that you are better off letting the market work for you rather than beating yourself up adopting complex, expensive and ultimately futile strategies to “beat” the market. This is the approach of WARR HUNT when constructing portfolios for our clients.
Writing in The Financial Times on the Nobel, economist and columnist Tim Harford said Fama had helped millions of people by showing them the futility of picking stocks, finding value-adding managers or timing the market to their advantage.
“If more investors had taken efficient market theory seriously, they would have been highly suspicious of subprime assets that were somehow rated as very safe yet yielded high returns,” Harford wrote.¹
In The Sydney Morning Herald, journalist and economist Peter Martin said the world owes a great debt to Fama, who “demonstrated rigorously that if the supermarket crowd is big enough or if there are enough cars on the highway, you will get no advantage from changing lanes. Anyone who could have been helped will have already helped themselves.²
This might be a counter-intuitive idea to many. After all, in other areas of our lives, like business, the secret to success is to study hard, compete aggressively and constantly look for an edge over our competitors.
One of the other two academics that Fama shared the Nobel with this year – Robert Shiller – takes the view that markets can be irrational and subject to human error. In this, he is frequently cited as a philosophical opponent of Fama.
In practical terms, though, both men agree that it is very, very difficult for the average investor to get rich in the markets by trading on publicly available information. Most people trade too much or underestimate the unpredictability of prices.³
The “simpler” approach to investment is to adhere to some core principles:
- Align strategy to your Values, Desires and Aspirations
- Risk and return are related
- Diversify to reduce uncertainty
- Structure a portfolio focused on known market premiums
- Stay disciplined and focused
- Keep a lid on fees and taxes.
Yes, these are simple ideas, but to quote another philosopher (Leonardo da Vinci), simplicity is the ultimate sophistication.
