View of London

The largest companies of the United Kingdom greatly impact the British and world economy. The UK’s top 30 publicly traded companies, major components of the FTSE index, are presented here together with their activities, logos, sectors, and useful links.

London Stock Exchange logoIn the United Kingdom, companies become publicly listed companies – PLC – to get listed on the London Stock Exchange – LSE. Though they have to follow the rules of the British Financial Conduct Authority, companies that become publicly listed on the LSE can then gain access to capital from investors who acquire their stocks.

The FTSE 100 Index

To ease the understanding of the evolution of the British stock market and the broader UK economy, the stocks of the 100 largest companies listed on the London Stock Exchange are aggregated in the FTSE 100 index. Meaning “Financial Time Stock Exchange 100”, and often more simply referred to as FTSE, the FTSE 100 index is widely recognized as the benchmark index of the British stock market.

Calculated from the stocks of the 100 largest corporations by market capitalization listed on the LSE, the FTSE is a capitalization-weighted index where larger companies are weighted more heavily in the index. It represents around 70% of the total market capitalization of the companies listed on the London Stock Exchange.

  1. The list certainly goes a long way to explaining Brexit. Many of the companies are in the business of exploitation of others’ resources while the rest are mostly consumer oriented. Only one, (Rolls Royce) is a manufacturer. Almost all have a worldwide reach so they are unlikely to be disadvantaged by a hard Brexit.

    Over the last several years manufacturing in the UK by indigenous companies has been gutted. Steel is the last bastion and it’s going under as there are no few, if any, local customers. High paying manufacturing jobs have been replaced by service ones. These are disdained by all except even worse off immigrants from the poorer parts of Europe.

    Most companies that now make things in the UK are foreign owned, attracted there because of the economics. They seem to be able to run their factories far better than UK managers ever did (remember British Leyland?). When Brexit happens this will change. All will eventually leave throwing even more workers on the dole. European service workers will also depart and their payments into the welfare system disappear. With less income, Government will reduce welfare payments even further.

    The few that will not suffer are the rich landowners (the aristocracy owns 30% of UK land and over 50% is owned by 3,600 individuals, 0.6% of the population).

    It is not unremarkable that many Tory MPs are spearheading Brexit. After all, they are the traditional party of the landowners (remember corn laws?) and many of them are independently wealthy (champagne reception anybody?).

    It is interesting to note that Germany, France and Italy have all rid themselves of a rich landowner class and consequently have more equal societies. All have strong manufacturing bases. An excellent way of giving constituents purpose and benefits. For example in the auto industry, Germany has 3 champions, France 2 and Italy 1. The UK has none, despite of the fact that they excel at design. Most Formula 1 development is done there. Jet engines, radar, DNA are other examples of lost opportunity. It is also depressing that ARM, one of the most innovative computer chip designers saw fit to sell designs rather than manufacture them. They are now owned by the Japanese and their technology is going into Japan’s next supercomputer.

    Meanwhile back in the UK the unemployed in many parts of the country are without hope. They and pensioners are now clinging to the illusion of past glories (we won the war, didn’t we?) and have been bamboozled into thinking that Brexit is the cure for all their ills. Presumably they are comforted by the spectacle of an aristocratic tribe turning up for royal christenings, marriages and funerals dressed in 300 year old fashions draped with long dead animal fur. I wonder how long a deprived populace without much hope will be diverted by images of those ceremonies and a charming old lady being paraded through London streets in a 200 year old gilded horse drawn cart.

    Educated youth, most of whom are against Brexit will do as I did 50 years ago, simply leave. The rest of the world is crying out for skilled personnel they’ll have no trouble finding jobs elsewhere.

    PS I’m not suggesting the guillotine. UK society must become somehow more equal. I was born there but left after a small taste of working in British industry. I found the US and Europe working conditions far more welcoming and equitable.

    1. Thank god you left Philip, the last thing the U.K. needs are ignorant negative people such as yourself. I unfortunately read what you wrote and all I could think of was, this guy just lives in a world full of assumptions.

  2. What an interesting article. Found you by accident whilst checking FTSE.

    For someone like myself it has to be interesting to receive a response at this early hour. That sums up the Brits down to a Tee (never had to type down to a T before) of which I am one. It is as if we are constantly hypnotised. I always vote Tory because the others would take all I have got, which though more than well off that does not count as rich. Never think about the Royals very often since giving up newspapers but live near Blenheim and often think of the unfairness of one person fighting a battle gets all that when others can’t get a postage stamps worth. As with all wars many fought in the same battle. People pay them to get in and I have worn fur coats and been to Champagne receptions so am not thinking of myself. We don’t as you say manufacture anything we are really floating in a bubble.

    The Royals are very clever at contriving to be caring people. The aristocracy is technically broke but being kept by idiots who pay to see their houses and walk round their parks. Often wonder how we could have a fairer society is to be truly Christian read Chesterton. He calls it Distributism which is not socialism, founded on good intentions but is now politics of envy. Nor is it capitalism as we know it. It is founded on a strong family with enough resources to own some property and small business with a very limited role from the interfering state.

    The $64,000 question is how to achieve this without a violent revolution. I had a fairly privileged life and never had to work (but I am a woman) men should have the best jobs and mum look after the family. Can just remember when we had the butcher the baker the candlestick maker etc. My husband a doctor is a slave of the state and the non-professionals are wage slaves of big business. So strong families with proper values and government more localised and big business small and many again.

    However I fear we have all been sedated by something. The English are the sweetest but most stupid because they do not use their brains. Everyone knows something is wrong but they can’t see what it is. If you are a very wealthy man you won’t like what I’ve said but this would not be a rob everyone just a plan which Chesterton saw a hundred years ago. He prophesied all that has come to pass. I always said Germany won the Peace the war itself is irrelevant now and in a hidden way we in the west is practicing a type of eugenics. Women have been conned into thinking they can do everything when Like the Aristocracy only a few have really succeeded big time. Well you’ve woken me up. Thank you

  3. Phillip Hughes, spot on. 12 years ago I advised my daughter to leave this country as I considered it was doomed by Class, Conservatism and Apathy. She took my advice and has been living and working in New Zealand for 11 years. She has a better lifestyle and better pay now. The doom I foresaw for this country is accelerating: the rich are richer, the poor poorer. Apathy has lead to Brexit which will finish off this country completely.
