How to trade South Africa 40 Index: trading strategies and tips

JSE top 40 index: what you need to know

The tradeable South Africa Top 40 index, derives its price from the futures price of the JSE Top 40 index. The JSE Top 40 index is a basket price or weighted average price for the top 42 shares on the Johannesburg Stock Exchange (JSE).

Ironically, it is 42 shares which make up the top 40 index, as some shares (Investec and Mondi) have multiple listings on the exchange.

A list of the shares constituents which makes up the JSE Top 40 Index (in alphabetical order) is as follows:

This makes way for other companies that have grown significantly on the broader JSE, to replace some of the companies (if any) which have declined significantly over the three-month period. The list above reflects the latest 'Top 40' list as of the last index rebalancing which took place in December 2018.

Because the index is weighted using the market capitalisation of each component share, the bigger the company, the more influence it has on movements in the index. Traders of the South Africa 40 Index might not need to follow the whole JSE Top 40 list as most of the weighting (and movement) can be attributed to the Top 10 shares in the Index.

A list of these shares and their respective weightings in the index (as of January 2019) are as follows:

Naspers

Naspers becomes by far the most important share to watch accounting for more than a 20% weighting in the index (at present). Naspers derives a major influence in its movements through its large investment in Tencent Holdings. Tencent Holdings is listed on the Hang Seng stock exchange in Hong Kong. The Tencent share price will have priced in most of its daily movements ahead of Naspers opening on the JSE. Movements in the Tencent share price are mostly reflected in the Naspers share price and in turn the benchmark index.

BHP Group Plc

The BHP Group can also give an early indication as to how the index may be setting up for the day ahead. BHP trades on Australia’s All Ordinary Exchange, also ahead of BHP opening on the South African exchange. While not as heavy a weighting as Naspers in the index, it does help provide an early indication for the index price momentum early in the day.

Tips for trading South Africa 40 index

While looking at the top companies and news relating can help give traders of the South Africa 40 index a directional bias for the day, looking at shares Naspers and BHP ahead of the equity market open (9am) can help provide an early warning as to what to expect in the early hours of trade.

There are also other factors you should watch out when trading JSE top 40:

Be aware of movements on International Indices when trading the South Africa 40 Index

Major international indices, such as those from the US (Dow Jones Industrial Average and S&P 500) will often set the tone for movements on our local index. US and European equity markets are open past the close of South African markets, while Asian markets open well before the open of South African markets.

Traders of the SA 40 Cash Index might consider watching what’s happening in the global market place for context, direction and well as gauging a general sentiment for the trading day ahead.

How the rand can affect trading on the JSE Top 40 Index

Some of shares which form part of the Top 40 index earn their income in foreign denominated currencies, such as the US dollar, the British pound and the euro (to name but a few). A weaker rand would mean that when repatriating funds to South Africa, those companies would receive more of the domestic currency for their foreign currency.

Shares which derive most of their earnings in foreign currencies are known as rand hedge counters. More than 65% of earnings, from shares which make up the index, are derived in foreign currency.

In turn, a weaker rand can be considered positive influence on the Index as it would be considered positive for (rand) earnings in the shares that make up the index. Inversely, a stronger rand might be considered negative for these shares and in turn the index.

Notable rand hedge counters include the Naspers, Richemont, BHP Billiton and Sasol.
