Back in lesson 3, we saw that different assets can perform differently at different times. But what are these assets? And why should they go their own way?
An asset is something you can own, buy, and sell. It’s the opposite of a liability.
- A house that you own is an asset.
- Your mortgage is a liability.
One man’s asset can be another man’s liability.
Your mortgage is a valuable asset for your bank. You’re contractually obliged to pay it back, plus interest.
The main asset classes
Just as the natural world is divided into broad classes like mammals, fish, and fungi – and mammals then divided into cats, monkeys, and many more – the world of assets divides into big groups, with subdivisions.
In investing, these big groups are called asset classes.
The main ones are:
- Government bonds (UK Gilts or US Treasuries)
- Corporate bonds
- Shares – Also know as equities
- Commercial property
- Residential property (your house or someone else’s)
- Commodities – Especially gold, but also stuff like forests, cows, and oil
Different asset classes perform differently from each other for two main reasons:
- Economic conditions – Inflation, interest rates, and economic growth affect different asset classes differently, and at different times.
- Emotion – Investors (asset buyers) are by turns fearful and greedy.
Asset classes in (un) reality
Let’s consider a fictitious company: Brixton Unlimited Nappy Services (Stock market symbol: BUNS).
BUNS was founded in 2000 to sell nappies to mums across London.
To raise the money to get started, BUNS floated on the stock market by issuing 100,000 shares at £10 each, raising £1,000,000. These shares can now be freely traded between investors, so the price changes. Each share is a part ownership in BUNS, entitling the owners to a certain share of the company’s fortunes.
Note that only the initially floatation actually invested money into the company.
If you buy ten shares in BUNS from me, a fellow private investor, then no money goes back to BUNS. It’s similar to if you buy a 1930s semi-detached house or a Van Goch painting – no money goes back to the builder or to the artist from these second hand purchases.
Only shares issued directly by the company brings money back to its own coffers.
After a while BUNS wants to expand. It could issue more shares to do so – raising more money by dividing itself up to increase the shares in issue to say 200,000 – but that would dilute existing shareholders and reduce the price of existing shares.
Many BUNS directors are also BUNS shareholders, and they don’t like the sound of that!
Instead it issues 100,000 bonds at £1 each. These bonds promise to pay the owner 10% interest every year for 10 years, at which time they will be redeemed by the company (cancelled) and anyone owning the bonds will get £1 back.
The bond issue raises £100,000. The company spends £50,000 of it on a new nappy shop in Chiswick – an investment in commercial property. It keeps the other £50,000 as cash in the bank for future investment. The annual interest due to the bondholders is paid from the company’s earnings.
After a while, managers get fed up with the price of their nappies going up due to rising raw material costs. They use the £50,000 to buy a special kind of share – an ETF – which tracks commodities like cotton. They hope that if cotton prices go up, reducing profits, it will be partly offset by the ETF price rising, too.
Business goes well, and soon BUNS is making millions. It can easily pay the interest on its bonds and also pay shareholders an increasing dividend.
Eventually success goes to the directors’ heads, and they decide they deserve to work in classier surroundings. They’re also a bit bored of the boring nappy business. They buy several trendy paintings by the graffiti artist Banksy for the office.
They tell shareholders that the paintings are an investment in alternative assets!
Asset classes and risks and rewards
Different asset classes have different risk versus reward traits.
We’ve already seen, for example, how cash is the safest asset class. The riskiest mainstream asset class is shares, but the rewards can be higher, too.
As we saw in lesson three, however, a lot depends on when you buy your assets.
Asset classes or sub-classes can become overvalued as a whole – think Spanish property in 2008 or Dotcom shares in 1999 – as well as undervalued.
But the risk/reward tends to follow this fun graph:
Asset classes and diversification
Note the difference between an asset class, and an asset within that class.
- Tesco and Barclays shares are both assets from within the same asset class.
- Cash you keep in a Barclays bank account is from an entirely different asset class.
Many new investors think they are well-diversified because they have a portfolio of 20 different companies.
But all those holdings are in the same class: Shares!
- Vertical diversification – Splits money between several different asset classes.
- Horizontal diversification – Hold different assets within an asset class.
To achieve a well-diversified portfolio, an investor first splits her money between different asset classes, and then further spreads it around by buying different assets with each sub-division.
For example, allocating 20% of your money to equities gives you exposure to the asset class of shares1. If you put that 20% into a UK index-tracking fund, it is then further spread across the many companies that make up the index. Choose a global tracker fund and it’s spread even more widely.
- Vertical diversification helps protect you from stuff like a stock market crash or a property slump – or from missing gains because all your money is in cash.
- Horizontal diversification protects you from more local troubles, such as a company making a loss or a bond defaulting on the income it owes you.
The philosopher Francis Bacon had all this figured out 400 years ago, writing:
Money is like muck. No good unless spread.
By muck he means animal manure. Great if spread about to fertilize future crops. A potentially stinking liability if left in a pile in one corner!
- There are only six main asset classes you really need to know about.
- Cash, Shares, Bonds, Property, Commodities, Alternative Assets
- Within each asset class are many different specific assets
- Good diversification is spread between asset classes, as well as assets
