A Plain-English Guide to Market Risk

Most risk warnings say the same sentence — you may lose your money — and then stop. That is true, but it is not useful, because it does not tell you what to look at. Below are the kinds of risk that actually turn up, in the words people use rather than the words the documents use.

Price risk

The obvious one: the thing you bought is worth less than you paid. Nothing exotic has to happen. A company can miss an earnings forecast, a commodity price can fall, a currency can strengthen. Over short periods, price movement is closer to noise than signal, which is why time horizon matters more than most people expect.

Volatility risk

Two investments can end the year at the same price and be completely different experiences. One drifts. The other falls 25% in March, recovers in July and falls again in November. Volatility matters because it decides whether you are still holding the position when the recovery arrives — and because, with leverage, it can close the position for you.

Liquidity risk

Liquidity is how easily you can convert something back into cash at a price close to the one you can see. In a busy market for a large company, that is easy. In a thin market — a small listed company, an obscure digital asset, or any market during a panic — the price you can actually get may be well below the price on the screen.

Leverage risk

Leverage means controlling a position larger than the money you put up. It multiplies the outcome in both directions, and with some products losses can exceed the amount you committed. It also introduces a second failure mode: a position can be closed out at a loss during a temporary move, even if the price later recovers. We cover this in more depth in understanding leverage and CFD risk.

Currency risk

If you hold an asset priced in US dollars and you live in Australia, you own two positions whether you meant to or not. The asset can rise 8% in US dollars and still lose you money if the Australian dollar strengthens more than that. This catches people who think of themselves as holding one thing.

Concentration risk

Putting most of your money into one asset, one sector or one theme means one piece of news decides your outcome. Australian portfolios are often more concentrated than their owners realise, because banks and resources dominate the local index. Diversification does not remove risk; it stops a single event from being decisive.

Counterparty and provider risk

Somebody holds your money and executes your orders. That organisation’s own solvency, competence, licensing and client-money arrangements are part of your risk, and they are separate from anything the market does. It is why who holds the money is a better first question than what are the returns.

Behavioural risk

The least discussed and, for many people, the most expensive. Buying after a rise because it feels safe, selling after a fall because it feels unbearable, adding to a losing position to average down, or abandoning a plan under pressure. No product protects you from this; a written plan and an unhurried decision process help.

Putting it together

You cannot remove these risks, and any service claiming to protect your capital is describing a marketing position rather than a mechanism. What you can do is decide, in advance and in writing, how much you are prepared to lose, over what period, and what would make you change your mind. Then commit only money that could go to zero without changing your life.

If a website makes that harder rather than easier — by rushing you, by quoting returns, or by refusing to give you a fee schedule — that itself is information about the risk you are taking.
