Diversification is not about owning loads of random things. It is about not letting one bad decision, one sector or one country wreck the whole plan.

What diversification really means
Diversification means spreading risk across assets, sectors and regions so your future does not depend on one idea being right. For most beginners, a diversified global fund already does most of the heavy lifting.
Common mistakes
- Owning many funds that all do the same thing
- Thinking more holdings always means better diversification
- Confusing activity with risk control
Practical example
If most of your money is in one stock, one sector or one country, you are not diversified. If you want the simplest route, start with index funds for beginners and read how to start investing in the UK.
