Diversification: why spreading investments matters

This article explains what diversification is and how spreading investments can affect risk. It also explores how diversification can sit alongside cash savings and clears up some common myths.

3 key takeaways

Diversification means spreading money across different types of investments, markets or sectors so you are less reliant on any single one.

Diversification can lessen the impact of one poor‑performing investment on your overall position, but it does not remove the possibility of losses.

Cash savings and investments play different roles, and UK regulators expect comparisons between them to be fair and balanced rather than one‑sided.

The basics

The Financial Conduct Authority (FCA) describes

as spreading your investments across different products and areas so you are less dependent on any one choice to perform well. In simple terms, it is the opposite of “putting all your eggs in one basket”, because your money is divided between different types of investments rather than concentrated in a single place.

can involve holding different types of assets, such as shares, bonds and cash, and also

across different markets, sectors and countries. The idea is that these different parts do not all move in the same way at the same time, so your overall experience is influenced by a mix of outcomes rather than a single result.

UK regulators emphasise that all

involves risk and that the value of investments can go down as well as up, meaning you may get back less than you put in. There is no formula that guarantees a particular outcome, and accepting higher

also means accepting a greater chance that things may not turn out as hoped.

Within that context,

by diluting the effect of any single investment performing badly. If one investment or market falls in value while others are more stable or rise, the ups and downs across the mix can help to smooth the overall pattern of returns over time, even though losses are still possible.

The FCA gives examples of

such as spreading across many company shares instead of just one, and combining different types of investments like shares, bonds and cash. It also notes that investors can diversify across countries and regions so that their outcome does not depend entirely on a single market, such as the UK alone.

can also apply within a single type of investment, for example by holding shares in companies from different sectors rather than focusing on one industry. The underlying theme in the FCA’s material is that choosing from a range of options reduces reliance on any particular one working out well, even though it cannot eliminate

. When firms compare cash accounts with investments, the FCA expects the information to be fair and balanced, making clear that they are not direct substitutes and that each has distinct features.

The Bank of England describes inflation as a situation where prices rise over time so that money buys less than it did before, reducing its “purchasing power”. This means that, while cash in a bank account does not usually move up and down in value in the same way as an investment, inflation can still affect what that cash can buy in the future.

Illustrative example

Concentrated vs spread investments

Imagine two people each setting aside £1,000 for the long term. Alex puts the entire £1,000 into a single type of investment linked to one market, while Sam spreads £1,000 across several types of investments that can behave differently from one another, such as a mix of shares and bonds in different regions, alongside some cash. In a year when Alex’s chosen market falls by 20%, Alex’s £1,000 would fall to £800 if that single investment tracked the market closely. In the same year, Sam’s shares might also fall in value, but bonds or other holdings might fall less or even rise, so the overall outcome could be a smaller loss or a milder change in value, depending on how each part performs. This is illustrative only and does not represent a specific product or guarantee future conditions.

Common misconceptions

Myth

Diversification means you cannot lose money.

Reality

The FCA notes that diversification can dilute the effect of a single investment performing badly, yet it also stresses that investments can still fall in value and that you may get back less than you invested.

Myth

Diversification is only relevant for wealthy or very experienced investors.

Reality

FCA material explains that investors “large or small” can diversify, for example by using funds that pool money from many people and invest across a range of assets and markets.

Myth

Cash is always worse than investing.

Reality

The FCA makes clear that cash and investment products have different purposes depending on a person’s circumstances, objectives and risk tolerance, and requires firms to present comparisons between them in a balanced way rather than portraying one option as universally better.
