As they navigate private pain and the turmoil of the global financial crash of 2007-09, they increasingly value their friendship. Both characters are expertly drawn in this funny, touching story.

Plan for an explosion in personal wealth
By Magnus Heystek22 April 2021 12:35
The past ten years have not been a very good decade for most South African investors. Your pension and equity portfolio have not risen much over this period.

In fact, it was one of the lowest average ten-year returns in many decades. If inflation and transaction costs are taken into account, then most people today have much less in real terms than they think.

When the returns of the JSE over ten years are measured against the major world regions, the average returns were among the weakest in the world.

And as last week's article pointed out, yields in US dollar terms were round zero.
