How to trade AIM

AIM Shares

Buying shares in AIM companies, investors can own a tiny fraction of the business.

Due to the smaller size of most AIM companies, your risk and reward are amplified and the share prices can react accordingly.


When the business grows you can take advantage of any rise in the share price, however, the chances of the business failing are just as likely thus causing the price to fall or even drop to zero.



AIM CFDs and
Spread betting

CFDs and Spreadbetting are used to achieve leverage. 

Rather than pay the full value of a transaction, investors only need to pay a percentage of the whole trade value when opening the position.

What this means to investors is that they have to generally commit circa 25% (£2,500) margin to purchase £10,000 worth of shares. This is referred to as the ‘Initial Margin’.


The key point is that the margin allows leverage, so that investors can access a larger amount of shares than they would be able to if buying or selling the shares themselves, and allowing the opportunity to amplify returns either positively or negatively.

Spread bets and CFDs are complex instruments and come with a high risk of losing money rapidly due to leverage. 76% of retail investor accounts lose money when trading spread bets and CFDs with this provider. You should consider whether you understand how spread bets and CFDs work, and whether you can afford to take the high risk of losing your money. Professional clients can lose more than they deposit.


All trading involves risk.

The value of shares, ETFs and ETCs bought through a share dealing account, a stocks and shares ISA or a SIPP can fall as well as rise, which could mean getting back less than you originally put in. Past performance is no guarantee of future results.
