Portfolio
Also known as: Investment portfolio
In simple terms
Your portfolio is simply all your investments taken together — the whole collection of shares, funds, bonds and other holdings you own.

What does portfolio mean?
A portfolio is the overall mix of everything you have invested in — shares, funds, bonds, cash and anything else — looked at together rather than one holding at a time. It is the “big picture” of how your money is invested.
Thinking in terms of a portfolio helps you see how your investments balance each other, rather than judging any single holding in isolation.
How a portfolio works
The key idea is diversification: spreading money across different investments, sectors and regions so that a fall in one is cushioned by others. A well-diversified portfolio tends to have smoother ups and downs than a single share.
How you split a portfolio — for example between shares, bonds and cash — is often called its “asset allocation”, and it is usually set to match how much risk you are willing and able to take and how long you plan to invest.
How could this affect me?
Building a diversified portfolio is one of the most effective ways to manage risk, because you are not relying on any single investment to come good. It will not stop your total value falling in a wide market downturn, though.
Reviewing your portfolio occasionally — and rebalancing it back towards your intended mix — helps keep the level of risk in line with your goals. Diversification reduces risk but never removes it; your capital is still at risk.
Things to watch out for
- Diversification reduces risk but does not remove it — the whole portfolio can still fall.
- A portfolio crowded into one sector or region is less diversified than it looks.
- Chasing last year’s best performer can quietly concentrate your risk.
- Past performance of any holding is not a guide to future returns.
