Regime Risk in Investing
(The following is outside my usual topics but its an area of my expertise that I have not found anyone else talking about).
Wise investors use diversification to reduce risk. Any one investment might fail for many different reasons, but many different investments are unlikely to fail together. Additionally, what causes one investment to do poorly often causes others to do well. Rising energy prices hurt manufacturing (which buys energy) but not energy companies (which sell it). Rising wages hurt employers with many low-wage employers, but benefit businesses who sell to consumers. Classically, bonds and stocks tend to move in opposite directions under a given type of pressure, so almost all long-term investors will benefit from holding some of both. For most of history opportunities for diversification were limited, and a prudent investor might buy several plots of land, invest in a ship’s cargo, and make some loans to neighbours. In the 20th century, mutual funds allowed small investors to own dozens of different assets for low but significant costs. Today anyone with a bank account in Canada can buy an index fund that holds thousands of different assets around the world for around 0.25% of their investments per year. However, most of these funds lack one important type of diversification.
