...but your portfolio might be better off elsewhere.
There is strong evidence that investors around the world favour their home market and this is reflected in their portfolio holdings. The phenomenon is known as home bias and has remained a puzzle in academic literature for decades.
Despite barriers to international investment continuing to fall, most individual investors have remained overly invested in their domestic market. There are certainly practical reasons why some SA investors might not be invested in foreign stocks (due to individual constraints or liability matching, for example). But for those who can, the balance of evidence suggests that global diversification is worthwhile.

Universe consists of: Australia, Austria, Belgium, Canada, China, Denmark, Finland, France, Germany, Hong Kong, India, Ireland, Italy, Japan, Netherlands, New Zealand, Norway, Portugal, Singapore, South Korea, Spain, Sweden, Switzerland, Taiwan, UK, US.
From a returns perspective there is no blanket statement that can be made about foreign exposure – some individual markets have outperformed the SA market over this period and others have underperformed, with a few extreme outliers on both sides.
