Variety or mixed income streams is the spice of a balanced portfolio that can witstand shocks.

Let me categorize them into A, B, C and D.

A ACTIVE INCOME
Here you work for money or you are on pension after retirement or you are in your private busines SME or a private pension plan. This also includes the great majority of us,,,Salary earners in private and public sectors.

B PASSIVE INCOME FROM CAPITAL MARKET (STOCKS)

Here you invest in stocks locally or both locally or overseas with varying objectives depending on the individual age and risk appetide (speculation,growth,income) but does not include forex trading as the later at the moment is considered more as gambling.
This category also includes mutual fund and other capital market instruments managed by experts on your behalf locally or overseas.

C PASSIVE INCOME (REAL ESTATE)
This is the aspect of property investment for income (rent), growth (re-sale value) and might be speculation (more on resale value of land)

D PASSIVE INCOME (MONEY MARKET)

This is investment in Bonds, commercial paper, fixed / demand deposits, cash savings, and also includes saving in other esprcially convertible currencies (pounds sterling, dollar , Euro) as hedge against inflation.

Research has shown that it is ideal for an average individual to hold or belong to at least TWO categories.

A finacial intelligent individual must have portfolio in at least THREE categories

The percentage mix is of varying degrees and
and is a subject of debate but what is very important is the awareness.
