WorldWide Markets with Simon Brown is a weekly market briefing built around the practical work of watching portfolios in real time. It is anchored in South African investing, especially the JSE, but it rarely stays local for long. Brown connects local retail stocks, yields, unemployment data, budget politics, and the Rand to the global events that can reprice risk overnight. Oil matters. So do tariffs, bank results, gold, fuel prices, fertilizer costs, and the details hidden in a proposed Strait of Hormuz blockade. The show’s pace is brisk and openly time-sensitive, with recordings often marked by the Tuesday moment they were made. That matters because the subjects are moving. A court fight over tariffs can sit beside a Department of Defense press conference, while a South African fuel crisis can sit beside provisions or offshore trading news. The stock work is plain-spoken and numbers-aware. Brown looks at earnings beats, valuation methods, sector weakness, and whether apparent bargains are worth treating seriously. He also experiments in public with AI research workflows, including long company reports and DCF valuation, while stressing that assumptions and sensitivities can change the answer quickly. The format has recurring set pieces, including annual predictions with Mark Ashton and Keith McLaughlin, plus budget discussions with public and business figures. It can be informal, even wry, but the informality serves the analysis rather than replacing it. Brown is comfortable saying he does not know when events are unclear, which gives the show a useful discipline. The result is a market companion for investors who want more than price moves and less than academic distance. It is strongest when the week’s news is messy, because that is where its mix of local detail, global context, and practical portfolio thinking has the most room to work.
