Investments in a currency other than sterling are exposed to currency exchange risk. Currency exchange rates are constantly changing, which may affect the value of the investment in sterling terms. You could lose money in sterling even if the stock price rises in the currency of origin. Stocks listed on overseas exchanges may be subject to additional dealing and exchange rate charges, and may have other tax implications, and may not provide the same, or any, regulatory protection as in the UK.

The stock market may seem overwhelming when you first start looking at it. There are so many companies listed on it! It can help to break it down into stock market sectors.

Generally, there are 11 main UK stock market sectors. 

Splitting the stock market into these sectors can make it easier to compare companies with similar business models. It can also make it easier to spot companies in the sectors you are most interested and/or comfortable with. This can help you decide what to invest in.

So, how do you establish what makes a stock market sector? Let’s take a look.

What is a stock market sector?

A stock market sector is a group of companies on the stock market that share similar qualities.

The Global Industry Classification Standard (GICS) was designed in response to the need for accurate and uniform definitions across the stock market.

The GICS has split stock markets into 11 sectors. These can be further divided into smaller categories. But, for the purpose of this article, we will focus on the 11 main sectors.

Frequently Asked Questions

A stock market sector is a group of listed companies that share similar business activities, or sell similar types of products and services.

Following the GICS principles, there are 11 stock market sectors. However, some have subdivided these into as many as 37 market sectors in the UK.

There is no one sector that is better than the others on the stock market. At times different sectors will outperform the others.

For example, in recent years information technology stocks have performed incredibly well, but now these stocks are falling while commodities are rising. 

As it is near impossible to predict market movements, it is generally recommended to have a diversified portfolio and invest across a range of sectors.

Most research platforms allow you to sort companies by market sector. This means, for example, you can view all companies in the healthcare sector at once. 

This way you can compare key metrics - like market cap, share price, etc. - easily and see which companies are outperforming their competitors. 

You can also look for common trends and themes impacting the specific sector. For example, rising interest rates will have an impact on financial services companies. This will give you an idea of how the sector is performing as a whole - not just individual companies.
