Stock Market Investing: Focusing on Growth and Margins, Not a Casino
Long-term investing favors companies with rising revenues and profit margins, especially those with smaller caps.
The market isn’t a roulette wheel. Real investing means spotting companies growing sales and squeezing more profit out of their operations over time. Big names like Nvidia shine but can be too pricey to double your money anytime soon—the bigger the company, the tougher the math. That’s where smaller, well-run firms come in. Think of Silicon Motion Technology, which is smaller and growing fast, needing less market cap expansion to deliver strong returns. In South Africa, this mindset nudges me toward nimble, growth-oriented companies like Prosus, which combines tech exposure with a more reasonable valuation than mega-caps like Naspers. Watch revenue growth and margin trends, not just share price moves. But beware: faster growth companies can stumble if economic conditions tighten or global tech demand slows. For now, patience and a focus on fundamentals beat chasing flashing lights on the ticker. this is just our opinion and not financial advice
Buy growth South African tech exposure via Prosus and selectively trim the largest caps where valuations are stretched. Avoid speculative short-term plays. Hold USD/ZAR exposure as a hedge against local market volatility.
