What is Indices Knowledge?

 A knowledge of powers, or indices as they are often called, is essential for an understanding of most algebraic processes. In this section of text you will learn about powers and rules for manipulating them through a number of worked examples. In order to master the techniques explained here it is vital that you undertake plenty of practice exercises so that they become second nature. After reading this text, and/or viewing the video tutorial on this topic, you should be able to:

• simplify expressions involving indices

• use the rules of indices to simplify expressions involving indices

• use negative and fractional indices.

Indices are weighted index of the top shares on a particular exchange, like the US30 (Dow Jones 30) and the New York Stock Exchange. With an Trade XN account you can trade a wide range of global indices with no overnight financing costs and low margin requirements.

What are indices in trading?

Index trading is a popular way for traders to gain exposure to financial markets without having to invest in individual company stocks, bonds, commodities or other assets directly. 

Those who are new to financial markets often start with index trading, meaning they trade an index-tracking fund or a basket of shares, instead of buying and selling individual company stocks.

By tracking the performance of a large group of shares, a stock index aims to reflect the state of a broader market, for example, the stock market of a country or a specific sector. This means that indices tend to be diversified. 

Every one of the world’s major financial markets has at least one stock index to represent it. For example, the S&P 500 (US500) is an index of the 500 largest companies in the US. As these benchmark indices often reflect the performance of the overall stock market, movement in the benchmark’s value indicates the health of the economy or industry sector it tracks.

Another benchmark index, the Euronext 100 (N100) tracks the performance of the largest stocks on Europe’s Euronext exchange, comprising companies listed in the Netherlands, France, Belgium, Portugal and Luxembourg. Equity indices provide benchmarks for fund managers to measure their actively-managed fund performance against. Fund providers also create passive index-linked funds, associated derivatives are also available for investors to buy and sell. 

Passive funds, also known as tracker funds, hold stocks in the same proportion as the index to match its performance. Active funds are managed by fund managers, who aim to outperform the index. Fund managers charge an annual fee as a percentage of the fund’s value.

Exchange-traded funds (ETFs) are an increasingly popular way for investors to get started with stock indices trading. ETF fund managers, such as Vanguard, charge relatively lower fees, allowing investors to keep more of their returns. 

As they are traded on exchanges, the price of these funds fluctuates throughout the trading session, unlike a mutual fund for which the price is settled once daily. ETFs can be bought and sold quickly and easily through stock trading platforms.

Dividends paid on the company stocks in an index-tracking fund can be distributed to investors,  known as a distribution fund, or reinvested back into the fund, known as accumulation fund.
