Platform and SIPP provider AJ Bell has added the Aquis Stock Exchange (AQSE) to its online trading platform to expand the investment choices available for clients.

AQSE provides access to about 90 listed growth companies.

Companies listed include a number of UK and European firms including Arbuthnot Banking Group.

The stocks are available to retail investors via AJ Bell Youinvest and to investors that use a financial adviser via AJ Bell Investcentre.

AQSE stocks are available for online trading via AJ Bell’s ISAs, SIPPs and Dealing / General investment accounts.

AJ Bell says the companies quoted on AQSE are divided into two segments 'Access' and 'Apex'. The Access market focuses on earlier stage growth companies, while Apex is the market for larger, more established businesses.

The average market capitalisation on Apex stocks is £80m and includes names such as Chapel Down, KR1 and Samarkand Group.

Andy Bell, CEO at AJ Bell, said: “Our goal is to make investing easy for our customers, whether they are managing their investments themselves or with the help of a financial adviser. Many of them have told us they want to be able to trade stocks listed on Aquis Stock Exchange and we are pleased to make this available to them.”
