Does 'Invest in What You Know' Still Work in SA Markets?

Peter Lynch’s famous strategy made waves, but should South African investors rely on it today?

Peter Lynch turned $18 million into $14 billion with a simple rule: buy what you understand. It sounds obvious, but it worked because he combined deep knowledge with careful analysis. Today, that approach still has merit but with caveats, especially here in South Africa. Local companies like Naspers and Prosus offer a familiar playground for many, thanks to their global digital exposure—something South Africans encounter daily. But relying solely on familiarity can blind you to valuation risks or market shifts. Take Sasol: a household name, but constant operational and commodity price challenges make it less predictable. Meanwhile, currency moves like USD/ZAR swings can throw a wrench in returns, particularly for companies reliant on exports or dollar-denominated debt. The magic is in blending personal insight with solid financial discipline—much like Warren Buffett with his Apple investment. If you get too cozy with what you 'know,' you might miss red flags or better opportunities elsewhere. this is just our opinion and not financial advice
