The idea

An asset class is a group of investments that behave in similar ways. The main ones are: shares (owning part of companies), bonds (lending to governments or companies), cash and cash equivalents (savings and very short-term, low-risk holdings), property (land and buildings), and commodities (raw materials such as gold, oil or grain). Beyond these sit “alternative” assets — private businesses, collectibles, digital currencies and more — which are usually harder to value, harder to sell and riskier.

Each asset class has a typical role. Shares have tended to offer the highest long-term growth with the largest swings. Bonds have tended to be steadier and to provide income. Cash is safe and reachable but grows slowly. Property can provide income and growth but is illiquid and lumpy. Commodities can behave differently from shares, but produce no income of their own.

Why it matters

Knowing the main asset classes gives you a map. Any investment you are offered belongs somewhere on it, which makes its likely risks and rewards easier to understand.

A real example

The situation

A relative tells Arash he should invest in “the market”, another suggests property, and a friend suggests gold.

What happened

Once he sees them as different asset classes with different roles, he understands they are not competing answers to the same question. He decides his first step is a broad mix for the long term and leaves property for later.

The takeaway

Seeing the map turned conflicting advice into different tools for different jobs.

How people actually behave

People tend to invest in whatever asset class those around them talk about most, or whatever has risen recently, rather than choosing based on the role it would play.

Common mistakes

• Treating one asset class as the only “real” investment.
• Choosing assets because they recently rose, not because of their role.
• Underestimating how risky and illiquid alternative assets can be.

Questions to think about

• Which asset classes do you currently own, directly or through a pension?
• Which role — growth, income, safety — matters most for your goals?

Try it: Place it on the map

1. Think of an investment someone has mentioned to you.
2. Decide which asset class it belongs to.
3. Write its likely role and its main risks, based on that class.

Words in this lesson

• Asset class — A group of investments that behave in similar ways, such as shares, bonds, cash, property or commodities.
• Commodity — A raw material or basic good, such as gold, oil, metals or grain, that is traded in large quantities.
• Alternative asset — An investment outside the main classes of shares, bonds and cash — such as private companies, collectibles or digital currencies. Often harder to value and sell, and riskier.
