What is FTSE 100? Explaining to your kids and teens

Are you confused by stocks, shares, and the FTSE 100? If so, you’re not alone. Unless you work in finance, it can seem a daunting subject to unravel. The good news is that it’s simpler than you might think. Here’s the FTSE 100 explained.

What is the FTSE 100?

The FTSE 100 is an index of the shares of the 100 biggest companies by market capitalisation on the London Stock Exchange (LSE). You can trade the index's price movements, or buy, sell or short shares of the constituents of the index. 

 

Created in 1984, the FTSE 100 is the largest stock exchange in Europe and lists thousands of stocks from 60 different countries.

What does FTSE stand for?

The FTSE is an acronym for Financial Times Stock Exchange. It was initially owned by the Financial Times and the London Stock Exchange but is now owned by the London Stock Exchange.

How is the FTSE 100 calculated?

Companies on the index are ranked in terms of their company's market value, also known as market cap for short. The FTSE 100 is, therefore, a list of the top 100 largest companies in terms of their value. This is worked out by the index:

 

  1. Multiplying a company's current share price by the number of shares sold to and held by investors.
  2. Then this is multiplied by the number of shares still left to be traded (sold). 

The resulting figure shows you how much a company is worth according to the market.

What kind of companies are in the FTSE 100?

The top 100 includes multinationals such as Unilever, BP, and HSBC holdings, and British 'blue chip’ (high-value safe investment) companies like Prudential and Vodafone.

How do you read the FTSE 100 index?

It sounds complicated to hear news of the FTSE 100, but once you get to grips with the jargon, it's relatively simple. 

  • As a company's share price increases, so will its market value, which changes the FTSE index.    
  • This may be followed by mentions of specific shares or industries that caused a significant gain or loss, such as the sliding of mining stocks (loss) or the rising housing market (gains). 
  • As a company's share price changes, so will its market cap, and the overall index will change in value.
  • How much a company moves depends on the company's weight (strength) in the index.  
  • So price fluctuations in price either way, in, say, big weighted companies like AstraZeneca or Shell, will have a more significant effect on the overall index than a smaller company.

Why is the FTSE 100 important?

The FTSE is important because the index's performance impacts investments, like retirement funds. 

 

The FTSE is also a good indicator of the UK and international economy as it changes in response to political and economic events. This, in turn, affects the confidence of investors who, when nervous about the economic outlook, sell their shares, and, when confident, buy more shares.

How can you invest in the FTSE 100?

There are two ways to invest in the FTSE 100:

  • By opening a share dealing account (either online or through a broker) and then buying through a trading platform.
  • Or you can invest in the whole FTSE 100 using an Index Tracker Fund.

What are some of the other indices out there?

There are approximately 5,000 US indexes. The three most widely followed are the S&P 500, Dow Jones Industrial Average, and Nasdaq Composite. Other examples include the S&P 100, the Russel 1000, and the Wilshire 5000 (also known as the ‘total stock market index’, as it contains all publicly traded companies that have headquarters in the US that have readily available price data).  In the UK, there is also the FTSE 250 (also known as the UK 250) and the FTSE AIM (Alternative Investment Market). In Japan, there is the Nikkei 225 and Tokyo Stock Price Index, commonly known as TOPIX.

How can you explain the FTSE 100 to kids and teens in simple terms?

The above may seem a dry subject for kids and teens, but you'd be surprised at how much kids and teens already know about investments and shares. Our latest Youth Economy Report found that 27% of US kids currently invest in cryptocurrency alone.

 

The best way to talk about the FTSE 100, investing, and shares is to make it age-appropriate and relevant to your child's life. For example, explain that anyone can own a little bit of their favorite company, be it Apple, Nike, or Netflix by buying shares in the company—and if you invest at the right time, you can grow your money. Shares are bought and sold at a stock exchange (a marketplace) via apps or through a broker.

 

An excellent example of how shares can make you money is Netflix. Their shares are currently worth $213 each. However, if you had been clever and bought Netflix shares twenty years ago, you would have paid 35¢ a share.

This means 100 shares in 2002 would have cost you $35.00, and today those same shares (had you kept them) would be worth $21,300!

 

However, be sure to explain that shares also go down. Especially if you invest in a company that doesn't do well, in which case you can lose all your money.
