Risk is a fundamental concept in investing.

Different investments carry different levels of risk, and those risks may influence how the value of investments rises or falls over time.

Understanding how investment risk works can help individuals better understand why investment values can fluctuate and how portfolios may be structured to manage those fluctuations.

What Is Investment Risk?

Investment risk refers to the possibility that the value of an investment may change, including the possibility that an investor may receive back less than they originally invested.

Different types of investments carry different levels of risk.

For example, shares in individual companies may fluctuate significantly in value, while some other asset types may experience different levels of volatility.

Understanding these differences is an important part of learning how financial markets operate.

Our article on stocks vs funds explained discusses different types of investments that may carry different risk characteristics.

Risk and Potential Return

Investment discussions often refer to the relationship between risk and potential return.

In general terms, investments that carry higher risk may also offer the possibility of higher returns over long periods.

However, there is no guarantee that higher-risk investments will deliver higher returns.

Market conditions, economic changes and company performance can all affect investment outcomes.

Types of Investment Risk

There are several types of risk that may affect investments.

Examples include:

  • Market risk – the risk that overall market movements affect investments
  • Company risk – risks linked to the performance of a specific company
  • Economic risk – broader economic conditions affecting markets

Because different risks can affect investments differently, investors often review how portfolios are structured.

Managing Investment Risk

Investment risk is often discussed alongside diversification.

Diversification involves spreading investments across different assets rather than relying heavily on a single investment.

Investment funds are also commonly used because they may hold many investments within a single structure.

Risk and Long-Term Investing

Investment discussions often emphasise long-term perspectives.

Because financial markets can fluctuate in the short term, some investors focus on longer time horizons when reviewing investment strategies.

Our guide on building wealth over time: long-term financial planning principles explains why long-term investing is frequently discussed within financial planning.
