How to Trade PRX (Prosus) on the JSE

This page explains exactly how to trade PRX, the ticker for Prosus N.V. on the Johannesburg Stock Exchange (JSE). You will learn what moves the share price, how the trading mechanics work, and what to check before you open a position through an online broker like JustMarkets.

Prosus is one of the largest technology investment holdings listed in South Africa. It is best known for its significant stake in Tencent, the Chinese tech giant, which means buying PRX gives you indirect exposure to one of the world's biggest internet companies. It trades under the ticker PRX on the JSE and is a heavyweight member of the FTSE/JSE Top 40 and All-Share indices.

For a complete newcomer, the appeal of PRX is simple: it lets you participate in global tech growth without leaving the JSE. But before you place your first trade, you need to understand spread costs, leverage risks, and how the broker you choose fits into the South African regulatory picture. This guide walks you through each step in plain language.

What is PRX?

PRX is the ticker symbol for Prosus N.V., a global consumer internet group and one of the largest technology investors in the world. Its biggest single asset is a roughly 25% stake in Tencent, the company behind WeChat and numerous gaming and fintech platforms. Because of that stake, PRX is often seen as a liquid, large-cap way to gain global tech exposure from a JSE-listed share.

The company is classified under the Technology sector, specifically within Investment Holdings. It is a large-cap stock, meaning its market value runs into the hundreds of billions of rand. It pays little to no dividend, so you are not buying it for income. High volatility is a feature of this share, not a bug. Price swings of several percent in a day are not unusual, especially when Tencent reports earnings or when Chinese regulators make policy announcements.

Retail investors in South Africa often compare PRX directly with Naspers, its parent company, because both offer exposure to the same underlying Tencent stake. The difference comes down to structure and the discount at which each trades relative to the value of their holdings. For many traders, PRX is the cleaner vehicle because it has a simpler share structure.

How to open an account

To trade PRX through a CFD broker, you first need an account. JustMarkets serves South African clients through its locally registered entity, Just Global Markets (Pty) Ltd, with registration number 2020/263432/07 and an office in Bellville, Cape Town. This entity is authorised by the Financial Sector Conduct Authority (FSCA) as a Financial Service Provider under FSP number 51114.

The sign-up process follows the standard FICA requirements. You will need a valid South African ID or passport, plus proof of address such as a utility bill or bank statement, usually dated within the last three months. This is a legal requirement under FICA, and no reputable broker will skip it.

The broker offers several account types to match different experience levels and budget sizes.

If you are brand new, the Standard or Cent account makes sense because the risk per trade is smaller. Once you understand how the platform works, you can consider the Pro or Raw Spread options, which reward higher volume with lower spreads but add a commission per trade.

Your first PRX trade

Once your account is funded, the process of buying or selling PRX as a CFD comes down to a few clear steps. A CFD, or contract for difference, lets you speculate on the price movement of PRX without owning the actual shares. You only put up a margin deposit, which is a fraction of the full trade value.

• Log in to the platform you chose during registration, either MetaTrader 4 or MetaTrader 5, on desktop, web, or mobile.
• Find PRX in the instrument list. It is usually listed under stocks or shares, and the full name will be Prosus N.V.
• Decide whether you think the price will rise or fall. Buy if you expect it to go up, sell if you expect it to drop.
• Set the trade size. This is measured in lots or shares, and the platform will show you the margin required.
• Add a stop-loss, which automatically closes the trade if the price moves against you past a set level.
• Click to open the trade and monitor it from the positions tab.

The key number to watch is the margin. At leverage of up to 1:3000, the margin requirement is very small compared with the full value of the trade. While this can magnify profits, it also magnifies losses. If the market moves against you, the broker may close your position automatically when your account equity falls below the required margin level.

Spreads and fees

Understanding the cost of each trade is non-negotiable. The spread is the difference between the buy price and the sell price, and it is how the broker earns money when you trade. For PRX, this can vary depending on the account type and current market volatility.

The overall cost picture for the different accounts looks like this:

JustMarkets states that there are no overnight charges for all clients, which means you will not pay swap fees for holding positions overnight. This is an unusual feature and can make longer-term CFD positions cheaper than at many other brokers.

Deposits via local bank transfer through EFT in ZAR are available, as are cards, crypto, Skrill, and Neteller. Processing is mostly instant to one day for deposits, and broker fees are not charged. Withdrawals are often processed within three hours on weekdays, which is far faster than the industry standard of one or two business days.

Regulation and safety in South Africa

Trading forex and CFDs is completely legal in South Africa when you use a properly authorised broker. The conduct regulator is the FSCA, and any broker serving retail clients must hold a Financial Services Provider (FSP) licence under the FAIS Act. For brokers that issue CFDs and act as the counterparty to your trade, there is an additional requirement to hold an OTC Derivative Provider (ODP) authorisation under the Financial Markets Act.

JustMarkets operates through its FSCA-licensed South African entity, which means your onboarding is handled locally and the broker is subject to South African conduct standards. You can verify the FSP number 51114 on the free FSCA register at fsca.co.za to confirm it matches what is listed on the broker's website.

The FSCA also publishes public warnings about unauthorised firms and impostors. It is worth checking the Media Releases page on the FSCA website before you fund any account. As of the review, the FSCA recorded roughly 1,247 forex-scam complaints in 2023, with about R547 million lost and only around 12% recovered. Most of these cases involved fake social-media recruiters promising guaranteed profits, so the safeguards are in place for a reason.

Tax on your PRX profits

From a tax perspective, South African residents are taxed on their worldwide income, including profits made through an offshore or locally regulated broker. The way your PRX profits are taxed depends largely on how often you trade.

If you trade frequently and actively, SARS will usually treat your profits as ordinary income, taxed at your marginal rate, which ranges from 18% to 45%. If you hold a CFD position for longer, the profit might be classified as a capital gain, which is taxed at a lower effective rate, but the distinction is not always clear and SARS has the final say.

As an active trader, you would normally register for provisional tax and file two IRP6 returns per year, due at the end of August and end of February, with a possible third top-up payment if you still owe. You would also file the annual ITR12 return. Trading-related expenses, such as data costs and platform fees, may be deductible, so keeping records of all costs is wise.

Funding without local payment networks

No broker is perfect, and it pays to know the weak spots before you commit capital. One limitation is the absence of a South African domestic payment network like Ozow built directly into the platform, though the broker does support local EFT in ZAR, which avoids the 2% to 3% conversion cost that banks charge when funding in dollars.

The high leverage ceiling also deserves caution. While the broker offers up to 1:3000, using that maximum on a high-volatility stock like PRX is a fast way to lose your deposit. The platform gives you the freedom, but it does not control your risk. That responsibility sits with you.

Another consideration is the mixed third-party review landscape. Independent review sites describe the broker as legitimate and regulated in South Africa, but those pages are often marketing-driven rather than primary regulatory records. The reliable check remains the FSCA register, not user reviews.

How to manage the risk

The line between a sensible trade and a reckless one is drawn by your position sizing. For a beginner, the rule of thumb is to never risk more than 1% to 2% of your account on a single trade. On a R10,000 account, that means your maximum loss on any one position should be R100 to R200.

A practical way to enforce this is to calculate your stop-loss distance before you enter the trade. If PRX is trading at 400 and you set a stop-loss at 380, your risk per share is 20. With a R200 risk limit, you can buy a maximum of 10 shares worth of CFDs. This calculation keeps leverage from turning a small mistake into a blown account.

The high volatility of PRX means wide price swings are normal. A stop-loss orders does not guarantee the price at which your trade closes during fast-moving markets, but it remains the most basic protection you have. Setting it before each trade forces you to acknowledge the risk upfront.

A liquid way to trade global tech

PRX offers a liquid, large-cap way to access global technology through a JSE-listed instrument, and JustMarkets provides a regulated FSCA path to trade it. For a beginner, the Standard account with its low minimum deposit and no commission structure is a reasonable entry point.

Sensible for:

New traders who want a low minimum deposit, local ZAR bank transfers, and no overnight fees. The FSCA-regulated local entity adds a layer of oversight that matters when you are learning. The no-swap feature also keeps holding costs predictable.

A stretch for:

Experienced traders who need deep liquidity, ultra-tight raw spreads, and advanced order types during fast market conditions. If your strategy relies on trading the exact open or close of the JSE session, you should evaluate whether the spread on PRX at that moment justifies the trade cost compared with other international broker options.

The practical takeaway is simple. Choose a broker that is FSCA-verified, start with a small account, use low leverage until your strategy is proven, and keep your position sizes small relative to your balance.
