10 Biggest Companies in the FTSE 100 List in Terms of Market Capitalization

FTSE 100 List| 10 Biggest Companies in Terms of Market Cap
The Financial Times Stock Exchange 100 index, also known as the FTSE 100 or more intimately termed the “Footsie," is a stock index that is comprised of the top 100 companies in the London Stock Exchange. The total capitalization of these companies is about 80% of all listed companies. Below, we'll take a look at a few of the most important and largest constituents of the FTSE 100 list of companies in terms of market capitalization. The FTSE index shows how successful top companies in the United Kingdom are. Although, part of the FTSE 100 comprises other global companies, which is why it is wrong to use the FTSE 100 as an indicator to ascertain the current state of the United Kingdom economy.

What is Market Capitalization?

First of all, let’s look at what market capitalization (or market cap) is all about. Market cap is the overall value of a company’s outstanding shares. Market cap is calculated by taking the outstanding shares of the company and multiplying it by the current price of its share. Additionally, a company’s market cap is what determines whether it will be included in the FTSE 100 list or not.

For instance, if a company has 2 million shares and is selling each for $20, it means each of the shares will have a market capitalization of $20 million. In other words, you can purchase such a company for $20 million if you have such money, and the stockholders are willing to sell their shares.

About the FTSE 100

The FTSE 100 index is made up of the top 100 LSE companies in terms of market cap as calculated on December 31 of the year. Operating since January 3, 1984, the index is run by a subsidiary of the London Stock Exchange Group, termed the FTSE Group. During its inception, it began with a value of 1000 and has experienced changes beyond recognition, such as disappearing companies, takeovers, and mergers.

However, in 2000 the FTSE 100 index increased to 7103.98 in terms of value. Notwithstanding, due to the financial crisis in 2007 – 2010, the index value got to its lowest level of 3500. Then in March 2017, it got to its highest value in intraday trading with a record of 7777.62 points.

Price changes are calculated in real-time and, when the market is open, they are published every second. While many index funds give a glimpse into the health of a particular economy, this is not true of the FTSE 100. That is because the FTSE is made up of many globally focused companies and additionally because it is significantly affected by exchange rates.

The FSTE index price is affected by various things such as economic shifts, politics, news, etc. that take place in Europe. However, announcements from the United Kingdom that affects FTSE include UK inflation rates, manufacturing numbers, GDP statistics, and Interest rate announcements.

FTSE 100 Trading Strategies

One of the efficient ways to start trading the FTSE100 is to use technical analysis patterns. It helps to identify turning points in the market and therefore areas for buying and selling. A popular price action pattern is the engulfing candle pattern, which comes in two types: a bearish pattern and a bullish pattern. Candlestick combinations can give powerful BUY or SELL signals. There are patterns indicating trend prolongation or reversal. The taken signals must be correlated with other data. For example, with the same indicators.

The traders commonly use the following strategies to deal with FTSE 100 blue chips:

  • trading using technical (graphical) analysis;
  • trading using reversal candlestick patterns: Hammer, Hanging Man, Inverted hammer, Shooting star, Doji, and Engulfing;
Trading hours are daily from 8:00 to 16:29 GMT (closing deals) and the closing of trades itself takes place at 16:35. All daily data on the index is published in the Financial Times from the day the index was calculated.

What moves the FTSE 100’s price?

The FTSE 100 rate is primarily influenced by factors related to the economy of Britain and the EU:

The pound rate, interest rates of the Central Bank; reports on GDP, production indices, inflation; as well as the political situation (Brexit), changes in tax legislation, export volumes, etc.

Bad data usually negatively affect the FTSE and lead to its fall and vice versa.

Much also depends on the specific composition of the FTSE index and its constituents at the current moment, for example, the more oil companies there are, the more the index is exposed to events affecting the hydrocarbon market, etc.

Even many British companies still receive the largest share of profits from exports to other countries, so their revenues are usually indicated not in a local currency, but in USD.

If you are an individual, there are two ways of investing in the FTSE 100 companies. The first method is by trading, while the second is by investing in this company.

Can you buy FTSE 100 shares? 

The FTSE market comprises the top 100 largest companies in the London Stock Exchange, including companies such as Barclays, HSBC, Sainsbury, BP, and Unilever. Although you can invest directly in the FTSE, however, you can also buy the shares of these companies through an exchange-traded fund that records the performance of the stocks in the market.

What is the difference between FTSE 100 and 250? 

The FTSE 100 is a list of the biggest 100 companies on the London Stock Exchange. Its total index value is placed at £1.3 trillion.
