What is Diversification?

"Do not put all your eggs in one basket" is the oldest advice in investing. Diversification is about spreading risk across many stocks, sectors and countries — so that one bad investment does not ruin your entire portfolio.

The oldest wisdom in investing

Imagine putting all your savings into one stock. The company goes bankrupt. You lose everything. That is the opposite of diversification.

Diversification simply means spreading your investments across many different stocks, sectors and ideally countries. So that when one investment goes badly, the others save you.

"No one can take from you what you have wisely distributed." — Florence Scovel Shinn

Three levels of diversification

Across stocks
Instead of buying only Equinor, you buy Equinor, DNB, Mowi, Telenor and Kongsberg. Then you are not dependent on one company succeeding.
Across sectors
Spread investments between energy, finance, technology, seafood and healthcare. Different sectors react differently to the same events in the global economy.
Across countries
Norway is a small market. By also investing in the US, Europe and Asia you reduce the risk of Norwegian problems destroying your entire portfolio.
Rule of thumb: 15-20 stocks in at least 5 different sectors provides good diversification for most private investors.
Common mistake: Many think they are diversified because they own 10 stocks — but all are oil companies. That is not diversification, it is concentration in one sector.
"Fear is only faith in the wrong thing. Spread your faith — and your investments — far and wide." — Florence Scovel Shinn
