Introduction to Financial Indices

In this comprehensive guide, we will delve into the intricacies of financial indices and how they are key indicators that track the performance of a specific group of stocks or other financial instruments.

Financial Indices offer valuable insights into the overall market or a particular sector’s health.

Understanding the Importance of Financial Indices

Before we dive into specific types of indexes, it’s vital to understand their significance, what financial indices do and how they play their role in the investment world.

Here are a few reasons how investors can use them to their advantage:

  1. Market Benchmark: They provide a benchmark against which the performance of individual investments can be measured.
  2. Portfolio Diversification: They guide investors in diversifying their portfolios with a broad asset allocation.
  3. Economic Indicators: They serve as indicators for the overall health of an economy or a specific sector.

Types of Financial Indices

According to Interactive Investor:

“There are nearly 3.3 million stock market indices around the world, according to new research from the Index Industry Association (IIA).

According to the World Bank, there are 43,192 public companies in existence, and there are more than 70 times as many stock market indices as there are actual stocks listed across the globe. 

At first glance, the booming popularity of passive investments seems the most obvious reason behind the index-mania.”

Stock Market Indices

Stock market indices track the performance of a selection of stocks. The most famous examples include:

  • Dow Jones Industrial Average (DJIA): Comprising 30 significant U.S. companies.
  • S&P 500: Consists of 500 of the largest U.S. publicly traded companies.
  • NASDAQ Composite: Includes more than 3,000 companies, largely in the technology sector.
  • FTSE 100: The top 100 companies traded through the London stock exchange.

You can read more about S&P 500 index funds in our SPDR blog, which highlights their SPY ETF, one of the most popular and successful ETFs available, which delivers a year-on-year return of approximately 10%.

Bond Indices

Bond indices keep track of the performance of various bonds. Notable examples are:

  • Bloomberg US Aggregate Bond Index: Represents government and corporate bonds in the U.S.
  • J.P. Morgan Emerging Market Bond Index: Monitors bonds in emerging markets.

Commodity Indices

These indices track a basket of commodities. Examples include:

  • S&P GSCI: Monitors 24 commodities, including agriculture and energy.
  • Bloomberg Commodity Index: Tracks 22 commodities in the investment grade.

Real Estate Indices

Real estate indices measure the performance of real estate markets. For example:

  • Dow Jones U.S. Select REIT Index: Focuses on real estate investment trusts in the U.S.

How to Invest in an Index

The best way to start index investing is through an Index Fund. These can come in the form of Mutual Funds or ETFs (Exchange-Traded Funds), both very liquid assets traded daily.

Mutual Funds are usually actively managed, where you pay for the services of a fund and manager, whereas ETFs are what is known as a passive investment. Passive investments track an index through a computer-generated market capitalisation strategy.

Most savings and retirement plans will give you access to a broad range of index funds. You can read more about them here.

Also, trading through a Lump Sum investment is very easy as investment platforms or portfolio bonds will give you access to a limitless amount of options. You can read about Lump Sum investing here.

Always check the historical performance of index funds and the fees charged. An Index Fund calculator is a useful tool. Speak to a professional, someone who is an expert financial advisor on index funds.

When investing offshore, you benefit from how tax-efficient index funds are and as you are now an expat, you should take full advantage of all the benefits of living overseas.

3 scales symbolising balancing indices

Calculating Financial Indices

There are three main methods of calculation:

  1. Price Weighting.
  2. Market Capitalization Weighting.
  3. Equal Weighting.

Price Weighting

This method involves calculating the index value based on the price of each component. The DJIA is an example of an index that uses this method. (The value of each holding is related to the price you pay for it)

Market Capitalization Weighting

Here, the index value is calculated based on the market capitalisation of each component. The S&P 500 uses this methodology. (The value of each holding is related to the overall holding it occupies in the index)

Equal Weighting

This method gives all components equal weight regardless of price or market capitalisation. (Every holding is equal to 1% if the index tracked 100 stocks)
