Understanding the JSE: How the Johannesburg Stock Exchange Works
Understanding the JSE: A beginner's guide to how the Johannesburg Stock Exchange works. Learn about shares, the Top 40, and how to start investing in SA.
If you have ever driven through Sandton, you have seen it.
Located on Maude Street, surrounded by glass skyscrapers and luxury hotels, sits a building that serves as the financial heartbeat of our continent. It is the Johannesburg Stock Exchange (JSE).
For many of us, the JSE feels like a fortress. We see the scrolling tickers on the news, hear words like “All Share Index” or “Bull Run,” and we zone out. We assume that world is reserved for men in grey suits, hedge fund managers, and people who understand complex mathematics.
But here is the “Soft Life” secret: The JSE is not a fortress; it is a marketplace. And just like you know how to navigate a Woolworths sale or haggle at a market, you can learn to navigate the JSE.
Understanding the JSE is the difference between working for money and making your money work for you. It is the difference between being a consumer of South African life and being an owner of it.
As Thando, your City Insider, I am going to demystify the beast. We are going to strip away the jargon, look at the mechanics, and explain exactly Understanding the JSE: How the Johannesburg Stock Exchange Works—so you can claim your seat at the table.
What Actually is the JSE? (The Mall Metaphor)
Let’s keep this simple.
Imagine a giant, high-end shopping mall. In this mall, the “shops” are companies. Big South African companies you know and use every day—Shoprite, MTN, Discovery, Sasol. The “products” they sell aren’t clothes or groceries; they are tiny slices of ownership in their business. These slices are called shares (or equities).
The JSE is simply the landlord of this mall. It provides the infrastructure, the security, and the rules to ensure that the buying and selling of these shares happens fairly and safely. It connects people who have money (Investors/You) with companies that need money to grow.
- When you buy a share: You become a part-owner of that company. If the company makes a profit, you get a cut (dividends). If the company becomes more valuable, your share price goes up.
- When you sell a share: You are cashing out your ownership to someone else who wants in.
A Quick History Lesson
The JSE is old money. It was founded in 1887 during the gold rush. Back then, it was just guys shouting orders in a tent to fund gold mines. Today, it is the largest stock exchange in Africa and one of the top 20 in the world. It’s world-class tech, right in our backyard.

Why Should You Care? (Inflation vs. Wealth)
You might be thinking, “Thando, I have a savings account. Why do I need the stress of the stock market?”
Because of the silent thief called Inflation. In South Africa, the cost of living rises by roughly 4-6% every year. If your money is sitting in a standard bank account earning 3% interest, you are actually losing purchasing power every year. You are getting poorer safely.
The JSE is historically one of the few places where returns outpace inflation over the long term.
The “Soft Life” Rationale:
- Passive Income: Imagine getting paid by Vodacom every time someone makes a call, or by Checkers every time someone buys groceries. That is what dividends are.
- Compound Growth: Your money makes babies. Then those babies make babies.
- Voting Rights: As a shareholder, you technically have a say in how the company is run.

Key Concepts Decoded (No MBA Required)
To understand the JSE, you need to speak a little bit of the language. Don’t worry, it’s easier than learning Zulu.
1. The ALSI (All Share Index)
You hear this on the radio every evening: “The All Share ended 1% higher.”
- Translation: The ALSI is like a thermometer for the whole market. It tracks the performance of almost all the companies listed on the JSE. If the ALSI is up, the general “mood” of the market is good.
2. The Top 40
This is the VIP section. It tracks the 40 biggest companies on the exchange by market value.
- Think: Naspers, British American Tobacco, FirstRand, Anglo American.
- Why it matters: These 40 companies make up about 80% of the total market value. If they sneeze, the whole JSE catches a cold.
3. Bull vs. Bear Markets
- Bull Market: Everything is going up. Optimism is high. Everyone is making money. (Think: An energetic bull charging forward).
- Bear Market: Everything is going down. Pessimism is high. People are scared. (Think: A bear hibernating or swiping down).
4. Market Capitalization (Market Cap)
This tells you how big a company is.
- Formula: Share Price x Total Number of Shares.
- Example: If a company has 100 shares and each costs R10, the Market Cap is R1000.
How the JSE is Structured: The Three Main Sectors
The JSE isn’t just one big pot. It’s divided into sectors, almost like aisles in a supermarket.
1. Resources (Mining & Commodities)
This is South Africa’s heritage. Gold, Platinum, Coal, Oil.
- Examples: Anglo American, Sasol, Sibanye-Stillwater, Gold Fields.
- Vibe: These stocks are volatile. They depend on global prices (e.g., the Dollar price of gold) and the Rand exchange rate. When they boom, they print money. When they crash, it hurts.
2. Financials (Banks & Insurers)
South Africa has a world-class banking system.
- Examples: Standard Bank, FirstRand (FNB), Capitec, Discovery, Sanlam.
- Vibe: Generally more stable. They pay good dividends. They are tied to the local SA economy. If SA does well, banks do well.
3. Industrials (Everything Else)
Retail, Tech, Telecoms, Medicine.
- Examples: Naspers (Tech giant), MTN, Shoprite, Clicks, Mr Price.
- Vibe: This is where you find the consumer-facing brands you love.
How to Actually Buy Shares (The Practical Steps)
You cannot walk into the building in Sandton and hand them R100. You need a middleman. This middleman is called a Stockbroker.
In the old days, brokers were expensive and intimidating. Today, technology has democratized access.
1. The Easy Access: Fintech Apps
Platforms like EasyEquities have revolutionized investing in SA.
- No Minimums: You can invest with R50.
- Fractional Shares: If a Naspers share costs R3,000 and you only have R100, you can buy a tiny fraction of that share. You still get the growth and the dividends (proportionally).
- Low Fees: Crucial for keeping your profits.
2. The Traditional Route: Your Bank
Most major banks (FNB, Standard Bank, Nedbank, Absa) have their own “Online Share Trading” platforms.
- Pros: Integrated with your banking app. Seamless transfers.
- Cons: Often have higher monthly admin fees or “minimum trade” fees than the fintech apps.
3. FICA and KYC
Before you trade, you must be verified. This is the law. You will need to submit:
- ID Copy.
- Proof of Address (not older than 3 months).
- Tax Number (from SARS).
Once your account is open, you transfer Rands from your bank account to your brokerage account, and you click “Buy.” It is literally that simple.
The JSE vs. The Economy: Are They the Same?
This is a common point of confusion. People ask: “Thando, why is the JSE hitting record highs when unemployment is so high and the economy is struggling?”
The JSE is not the South African Economy. Many of the biggest companies on the JSE (like Naspers, Richemont, BHP Group) earn most of their money outside of South Africa.
- Richemont: Sells Cartier watches to billionaires in China and Europe.
- Naspers/Prosus: Owns a huge chunk of Tencent (Chinese tech).
- Anglo American: Mines globally.
This is called Rand Hedges. When the Rand gets weaker, these companies often earn more in Rands because their earnings are in Dollars or Euros. This protects your portfolio when the local economy is tough.
Risky Business: Understanding Volatility
The “Soft Life” is about peace, so we must discuss risk. The stock market goes up and down. That is its nature.
- Volatility: The speed at which prices change.
- The Panic Sell: The biggest mistake new investors make is selling when the market drops.
- Scenario: You buy R1000 of shares. The market crashes. Your screen shows R800. You panic and sell. You have now locked in a R200 loss.
- The Soft Strategy: You wait. Historically, the market recovers. If you don’t sell, you haven’t actually lost anything yet—it’s just a “paper loss.”
Pro Tip: Never invest money in the JSE that you need for rent next month. The JSE is for money you don’t need for at least 3 to 5 years.
ETFs: The “Soft Life” Investment Strategy
If picking individual winners (Stock Picking) sounds stressful, there is a shortcut. It is called an Exchange Traded Fund (ETF).
Instead of trying to guess if Shoprite will beat Pick n Pay, you buy a Retail ETF. This gives you a tiny basket containing all the retailers.
- Satrix 40: One of the most famous ETFs. It buys the top 40 companies on the JSE. You buy one unit, and you instantly own a slice of the 40 biggest companies in SA.
- Diversification: If one company fails (like Steinhoff did), you don’t lose everything because you have 39 others holding you up.
For beginner investors, ETFs are the smartest, lowest-stress way to enter the JSE. Check out providers like Satrix to see the variety available.
Investing Responsibly: The ESG Factor
In 2026, we care about where our money goes. The JSE is very big on ESG (Environmental, Social, and Governance) investing.
- Environmental: Does the company pollute?
- Social: How do they treat their workers? Do they support B-BBEE?
- Governance: Is the board honest?
You can choose to invest in “Socially Responsible” funds on the JSE that exclude things like tobacco or fossil fuels if that aligns with your values.
Take Your Seat
Understanding the JSE: How the Johannesburg Stock Exchange Works is not about memorizing ticker symbols. It is about understanding the flow of wealth in our country.
When you buy your first share, something shifts in your psychology. You walk into Dis-Chem, and you aren’t just a customer buying vitamins; you are a shareholder checking on your stock. You drive past a construction site using PPC Cement, and you smile because you own a piece of it.
The JSE is an open invitation to build your future. The barriers are down. The apps are ready. The only thing missing is you.
Start small. Start today. And watch your “Soft Life” grow from a paycheck into a portfolio.

FAQ: Understanding the JSE
Q: Do I have to pay tax on my JSE profits? A: Yes.
- Dividends Tax: Usually 20%. This is often withheld automatically by your broker before you even get the cash.
- Capital Gains Tax (CGT): If you sell your shares for a profit, you may pay tax on that gain. However, you have an annual exclusion (an amount of profit that is tax-free) which changes, so check the latest SARS rules.
- TFSA: You can use a Tax-Free Savings Account to invest in JSE ETFs and pay zero tax on the growth. This is the ultimate hack!
Q: Can I lose all my money?
A: If you invest everything in one single company and that company goes bankrupt, yes. But if you diversify (buy many companies or ETFs), it is highly unlikely you will lose everything. The market fluctuates, but historically trends upwards.
Q: What is the JSE trading time?
A: The market opens at 9:00 AM and closes at 5:00 PM, Monday to Friday. No trading on weekends or public holidays.
Q: How much money do I need to start?
A: With platforms like EasyEquities, you can literally start with R10. There is no minimum.
Q: Is the JSE regulated?
A: Heavily. It is regulated by the FSCA (Financial Sector Conduct Authority). It is one of the safest and most transparent exchanges in the world.
